Top 21 AI Enterprise Search Tools

Facts and pricing verified September 8, 2026.

Glean tops this ranking and still won't tell you what it costs. That single fact is the shape of the whole category.

Glean earns first place on permission-aware search across 275+ connected apps, and on a compliance stack that runs to ISO 42001, ISO 27001, SOC 2 Type II, HIPAA, GDPR and TX-RAMP Level 2. Its official pricing doc describes a per-seat fee with no dollar figure attached.

Ten more tools here also route pricing through a sales call. Mindbreeze is the only one of them that publishes a plan price, exactly one of its four tiers, at EUR 83,000 per year.

So what if you need a number before a sales call? Nine of these twenty-one publish one of some kind. Narrow that to per-seat pricing under $25 a head and five survive.

Dashworks at $12 per seat per month, or $10 billed yearly. Onyx at $20 per user per month, with an MIT license if you'd rather host it yourself. GoSearch with a genuine free plan and a $20 per user per month Pro tier. Microsoft 365 Copilot at $18 per user per month annual, a promotional rate through Dec 31, 2026 against a regular $21. And Atlassian's Rovo Dev at $20 per developer per month.

Copilot is your default if most of your corpus already sits in Microsoft 365.

Here's the tension that makes this category hard. Eight of these twenty-one carry a public review base you can actually read. Three of the eight document accuracy that needs work: Guru's reviewers describe relevance degrading as the knowledge base grows, Coveo's say relevance isn't accurate out of the box without tuning, and Dashworks' report occasional accuracy issues.

The other five break somewhere else entirely. Cluster configuration and ongoing shard and replica work at Elastic, cost at Glean, setup at Moveworks, documentation and support at Kore.ai, support and billing at Algolia. Either way you learn what breaks before you sign.

Now the turn that matters to you. The three tools that ride on suites you may already run, Copilot, Rovo and Gemini Enterprise, carry no reachable independent review base at all. The standalone vendors you'd have to justify to procurement carry the volume instead: Guru at 2,957 reviews, Elastic at 525, Glean at 162, Coveo at 142.

The boldest numbers in this guide sit outside any review base. Support deflection climbing from 33% to 95%, EUR 7.2M saved at a central bank, a 299% return on investment. Each one comes from the company selling the product.

In fact there's a third unknown, and it's newer. Two of these twenty-one changed owners recently: Moveworks now ships under ServiceNow, whose acquisition closed December 15, 2025, and Sana is now part of Workday. Your decision is less about which product is best and more about which kind of unknown you can defend to procurement.

Quick picks

Best for enterprise: Microsoft 365 Copilot. Pick it because your corpus already lives in Microsoft 365 and Microsoft is already an approved vendor. Licensing runs from commercial plans through E7, plus GCC, GCC-High and DoD government clouds and Education, with Enterprise Data Protection, an EU Data Boundary and Microsoft Purview classification behind it.
Best integrations: Guru. Your people live in Slack and a browser, and Guru puts the answers there. 25+ native connectors including 25+ HRIS (human resources information system) platforms, plus Zapier, Workato and Prismatic, a REST API, and MCP (Model Context Protocol) compatibility with Claude, Copilot and Cursor.
Best value: GoSearch. A route to proof on your own content before you spend anything, with no credit card asked for and no clock running on it. A free plan, then $20 per user per month for unlimited search and AI answers, with SOC 2 Type II, GDPR compliance and a stated zero-data-retention policy.
Most dependable: Moveworks. When the security questionnaire is the hard part of your buy, this one arrives with the answers pre-filed. FedRAMP authorized, plus ISO 27001, SOC 2, HIPAA and GDPR, now owned by ServiceNow.
Best for power users: Glean. For knowledge scattered across dozens of systems, with a budget to match. 275+ connectors, a knowledge graph, no-code agent building and 40+ supported models, rated 9.5/10 for ease of use across 162 G2 reviews.

Four routes, and how to pick yours

Those five picks answer five different questions, and which one is yours depends on the route you're on. Twenty-one products is an unreadable list. Four decisions is not. Before you read a single entry, work out which route you're on, because the route eliminates more vendors than any feature comparison will.

Route one: buy a per-seat assistant you can price today. Four of the nine tools that publish a price are standalone per-seat products: Dashworks, GoSearch, Onyx and Sana AI. You can build a budget line this afternoon, take it to finance, and know within a rounding error what 400 seats costs.

Is that worth ranking a vendor higher for? On this route, yes. A number you can defend beats a demo you can't price. The alternative is a quarter of discovery calls.

Route two: turn on the search you already pay for. Buy the bundled tool because it's cheap and already approved. Don't buy it expecting it to reach whatever part of your corpus lives outside its own walls.

Microsoft 365 Copilot, Atlassian Rovo and Gemini Enterprise attach to suites many companies already run, so you are extending an existing vendor relationship rather than opening a new one. Only Rovo is included in that subscription: Copilot is a paid add-on from $18 per user per month on an annual commitment, and Gemini Enterprise is quoted separately.

Now look at the connector spread. Rovo lists 40+ and Gemini Enterprise names four (Confluence, Jira, SharePoint, ServiceNow), against Mindbreeze at 490+, Glean at 275+ and Sinequa at 200+. Is your knowledge split across two suites, SharePoint here, Confluence and Jira there? Then the bundled route is ruled out as a complete answer, and you'll be shortlisting a standalone vendor alongside it.

Route three: run a full enterprise procurement. Eleven vendors here want a conversation before a number. Ten of them publish no plan price, and Mindbreeze publishes one tier of four.

You get depth, connector breadth and certifications. You also get a sales cycle, and no way to compare cost until you're deep inside one. So cut that group down before you book anything. Gemini Enterprise is one of the eleven and route two already put it in front of you. Each of the other ten has a single condition that puts it on your list.

Moveworks if you have a FedRAMP requirement, or if you're already a ServiceNow shop.
Mindbreeze above 10 million documents.
Sinequa for the largest document estates.
Lucidworks for Reddit-scale query volume.
Hebbia only if you're in finance or legal.
Squirro for on-premises in a regulated shop.
Kore.ai if you already run its conversational stack.
Coveo for customer service and commerce.
Guru for knowledge management, with the largest review base in this ranking behind it.
Glean for connector reach across 275+ apps and a certification stack that runs from ISO 42001 to TX-RAMP Level 2.

Then price the ownership question into any multi-year deal you sign on this route, because Moveworks now ships under ServiceNow.

Route four: build it on infrastructure. Elastic, Algolia, Vectara and Dust hand your engineers the retrieval layer instead of a finished search box. Powerful, and it makes your team the owner of relevance quality forever.

Rule of thumb: if nobody on your team owns search after go-live, route four isn't for you, no matter how good the demo looks.

Which of the 21 does your route point at?

You have your route. Now spend it here. Which column do you read first? The one your route turns on. On route one that's Entry price. Route two, Connectors. Route three lives in the last two columns, Compliance highlights and Independent reviews.

One reading rule before you scan. In the compliance and reviews columns, a dash is an open question, not a zero. Treat it as the first item on your call agenda rather than a mark against the vendor.

The entries below tell you what each of those rows will cost you in practice.

Ranks 1 to 5: where most shortlists start

1. Glean, best for power users

Glean is what you buy when you want search to become workflow. The platform unifies retrieval across 275+ work apps and builds a knowledge graph on top. Add vector semantic search and a chat assistant. Then your non-engineers assemble agents without writing code, across 40+ models alongside Glean's own Waldo.

The trust stack runs deep. ISO 42001, ISO 27001, SOC 2 Type II, HIPAA, GDPR and TX-RAMP Level 2, with permission-enforced read and write plus end-to-end audit logging. Booking.com, Zillow, Samsung, Databricks, Reddit and Canva are named customers.

Across 162 G2 reviews, Glean scores 9.5/10 for ease of use, 9.2/10 for support quality and 9.0/10 for integrations, with reviewers naming the easy interface and simple app connections. The recurring gripe is cost: pricing needs a quote, and advanced model usage bills separately.

The bill: a per-user, per-month seat fee with no published amount. Then Model Hub usage charged at model-provider API rates, where Waldo runs $0.50 per million input tokens and $2.50 per million output tokens. Then a Flexible Model Management fee levied as a percentage of total LLM usage. Three moving parts, and only the token rates carry a published number before the call.

Vendor's own numbers: 3+ billion searches powered, 110 hours saved per user, 96.9% accuracy on prompt-injection detection, all self-reported.

2. Dashworks, the cheapest paid seat

Dashworks publishes the lowest paid per-seat price in this list, below Copilot's $18 and the $20 seats at GoSearch and Onyx. It answers your questions by live-querying your connected apps rather than holding an index of its own.

You pick the model too: GPT-4o, Claude, Gemini Pro or Llama 3. Connectors number 60+, across wikis, project management, CRM, messaging, code, HRIS and support.

That no-index architecture is also the security pitch. A stated zero-data-retention design, backed by SOC-2 Type 2 and HIPAA Type 1 attested by an independent auditor, with AES-256 at rest and TLS 1.2 in transit.

Capterra reviewers rate it 4.3/5 across 39 reviews, with 92% positive sentiment. They praise "quick, relevant results with source attribution" and "smooth onboarding and intuitive interface". They flag occasional accuracy issues, limited control over which sources get indexed, and trouble connecting less common proprietary systems.

The bill: Team is $12 per seat per month, or $10 billed yearly, with no seat minimum. Business is $15 per seat per month, $12 yearly, and carries a 10-seat minimum. Enterprise adds SSO, SCIM provisioning, API access and an uptime SLA by quote. A 14-day trial needs no credit card.

3. Elastic, for engineering teams

Elastic is the infrastructure answer. One API gives you BM25 keyword matching, vector search and semantic search together. The built-in ELSER model, retrieval-augmented generation (RAG) tooling and an Agent Builder for context-aware agents come with it.

Ingestion runs through OpenTelemetry, Logstash and Beats, with model connectors for OpenAI, Cohere, LlamaIndex, Amazon Bedrock and Anthropic Claude. Everest Group named it a Leader in its Enterprise Search Products PEAK Matrix 2026. Its Trust Center documents ISO 27001, ISO 27017, ISO 27018, SOC 2 Type II, PCI-DSS and HIPAA.

525 verified G2 reviews average 4.4 stars. Reviewers rate speed at scale and relevance tuning highly, with synonyms scoring 92%. They also say plainly that this is not plug and play: cluster configuration takes learning, and shard and replica tuning stays an ongoing job as data grows.

The bill: Cloud Hosted, priced on a 120GB two-zone baseline.

Standard: $99 a month.
Gold: $114 a month, adding reporting, Watcher and business-hours phone support.
Platinum: $131 a month, adding machine-learning anomaly detection and the 99.95% uptime SLA.
Enterprise: $184 a month, adding Agent Builder and SAML SSO.

Usage-based storage, data transfer and snapshot charges stack on top of whichever tier you pick.

4. Guru, best integrations

Nothing else here has a review base like Guru's: 2,957 reviews, 4.7/5 across 2,317 on G2 and 4.8/5 across 640 on Capterra. It's a knowledge-management platform first, with AI search layered over cards that carry verification badges, so your people can see what's current.

The integration list is why it wins this segment. 25+ native connectors cover Slack, Teams, Google Drive, Confluence, OneDrive, Salesforce, Jira, GitHub and 25+ HRIS systems. Plus Zapier, Workato and Prismatic, a REST API, and MCP compatibility with Claude, Copilot and Cursor.

Founded in 2013, $70.7M raised per its funding announcements, Shopify and SeatGeek among named customers.

What Guru's reviewers keep returning to: the interface is genuinely easy and onboarding is fast, the Chrome and Edge extension puts answers where work happens, and search accuracy degrades on larger knowledge bases, sometimes demanding exact terms. Filtering and findability get cumbersome as the base scales, and the content editor frustrates people who reorganize often.

So the condition is knowledge management. If that's the job you're hiring for, and you want the biggest pile of independent evidence behind your choice, Guru is your entry.

The pricing page won't help you get there. It offers "your investment is tailored to your organization's scale" and a call to book, with no free plan. Read the "10x AI workflow performance" headline as the vendor's own figure.

5. Microsoft 365 Copilot, best for enterprise

Is this the most capable search engine in the list? That's the wrong question. It's the one your security team has already approved. Copilot Search works as a universal search layer across Microsoft 365 apps and connected non-Microsoft sources, grounded by semantic indexing over Microsoft Graph.

Enterprise Data Protection extends Exchange and SharePoint-grade contractual commitments to prompts and responses, with an EU Data Boundary, Purview classification and data loss prevention, and permission-scoped results. Licensing reaches from Business through E7, into GCC, GCC-High and DoD government clouds, and Education.

Now the honest part. Microsoft's own guidance recommends running SharePoint Advanced Management and Restricted Content Discovery first, to declutter Copilot's data sources and improve the quality of the responses.

So what does that cost you before anything works? A decluttering pass that Microsoft's docs put ahead of deployment, on a timeline that guidance doesn't quantify. Budget for it before anyone judges answer quality. Note too that free Copilot Chat (Basic) is web data only, with no automatic access to your organizational content.

Everything above comes from Microsoft's own documentation, with no third-party review base reachable to check it against.

The bill: the Copilot Business add-on is $18.00 per user per month annual, a promotional rate through Dec 31, 2026 against a regular $21.00. Month to month it's $25.20, and it stacks on an existing Microsoft 365 Business subscription. Bundled options run $23.50 (Business Standard with Copilot) and $32.00 (Business Premium with Copilot) per user per month annual. A 1-month free trial is offered.

Ranks 6 to 10: strong products, one condition each

6. Moveworks, most dependable

Moveworks is built for the buy where the security review is the hard part. FedRAMP authorization, ISO 27001, SOC 2, HIPAA and GDPR, with Moveworks reporting 350+ customer organizations including 10% of the Fortune 500, and 6M+ employee users.

The Reasoning Engine performs hybrid retrieval, indexed and live API, across 50+ integrated apps with permission-aware results and inline citations. There's a Content Gateway for the systems that aren't on the list.

But the ownership question rides along with it. ServiceNow completed a $2.85 billion acquisition on December 15, 2025, so what you sign for now ships under ServiceNow's roadmap. The vendor puts typical time to value at 8 weeks.

125 G2 reviewers praise the natural-language handling of complex, multi-step requests and call support responsive. Their loudest complaint is setup: integration work is complex and time-consuming, and integration is reportedly harder for organizations that are not already on ServiceNow.

Two things put Moveworks at the top of your list. A FedRAMP requirement, or a ServiceNow estate you already run. Either one is worth accepting a sales quote for.

If you carry neither, you're opening a sales cycle for a quote you can't compare, and the priced entries above let you test on your own content first.

7. Coveo, for service and commerce

Coveo was named a Leader in the 2026 Gartner Magic Quadrant for Search and Product Discovery, and its feature depth backs that up. You get generative answering, conversational and product-discovery search, agentic retrieval through an MCP Server, a Passage Retrieval API and seven platform APIs.

Connectors are named and deep, covering Salesforce, ServiceNow, Sitecore, Adobe, Shopify, SAP Commerce and Zendesk. If your team wants to build the front end itself, you get developer libraries (Atomic, Headless, Quantic, Relay) and a CLI. G2 rates it 4.3/5 across 142 reviews, 52.4% of them from enterprise users.

Reviewers call the initial implementation "fairly simple and straightforward". Then they warn that relevance is not always accurate out of the box and needs tuning, and that "package/version upgrade is sometimes hard and require a lot of time/money investment". Documentation gaps and API rate limits create friction along the way.

Buy Coveo for the use case, not for the org chart. Customer service and commerce are where it earns its keep, and that's where you should test it.

On cost, plan for a metered line. Pricing runs in units of 100,000 queries per month for search, with separate Generative Queries per Month pricing on top. There's a free trial, and no lasting free plan.

8. Atlassian Rovo, already in your Atlassian bill

If your work already lives in Jira and Confluence, Rovo arrives with your subscription rather than a purchase order. Search, Chat and Agents run over the Teamwork Graph. Smart Answers come with source citations and follow-up prompts, and Knowledge Cards surface live project context instead of a list of blue links.

The connector list is genuinely broad at 40+ apps: Salesforce, ServiceNow, GitHub, GitLab, Bitbucket, Azure DevOps, Slack, Teams, Google Drive, SharePoint, Dropbox, HubSpot and Workday among them. Reddit, Cisco, Mercedes-Benz through the Atlassian Williams F1 Team, HarperCollins, Procore, Datasite and Sprout Social appear as customers.

What you can't do is check any of that against an outside reviewer base, because none is reachable for Rovo. Your trial is the evidence.

The bill: credits, pooled across your organization.

Plan	Credits per user per month
Jira and Confluence Standard	25
Jira and Confluence Premium	70
Jira and Confluence Enterprise	150
Teamwork or Service Collection Standard	250
Teamwork or Service Collection Premium	700
Teamwork or Service Collection Enterprise	1,500

Overage runs $0.01 per credit, $10.00 per 1,000, with admin alerts at 80% and 100% of the limit and spending caps available. Rovo Dev is separate at $20 per developer per month with 2,000 Rovo Dev credits included, and there's no standalone permanent free tier, only time-limited trials.

9. GoSearch, best value

GoSearch is the entry that respects your time. The free plan asks for no credit card and gives you 10 searches a day, 3 GoAI queries a day and one 5 MB file upload. That's enough to see whether the thing works on your content before anyone signs anything.

Underneath sits semantic search, an AI chat assistant, role-based custom agents and no-code multi-step workflows over 100+ connectors delivered three ways: indexed, federated and MCP. SOC 2 Type II, GDPR compliance and a stated zero-data-retention design round it out.

It's YC-backed and part of the GoLinks and GoProfiles suite, with HPE, Incode, Tonal and Camber Health named.

Worth knowing before you get attached: GoSearch carries no independent rating on record at G2, Capterra or Trustpilot. So that free plan is how you generate your own evidence rather than borrow someone else's.

The bill: Free is $0. Pro is $20 per user per month for unlimited searches, unlimited GoAI conversations and unlimited AI answers. Enterprise adds SSO, SAML, SCIM, the GoSearch API and bring-your-own model and cloud.

Vendor's own numbers: a Model N case study reports a 47% productivity boost in support operations, $400k in savings, 80% daily-active-user adoption within three months and a 49% reduction in ticketing backlog. Self-reported, and worth testing on the free plan rather than believing.

10. Sana AI, the Workday question

Who owns Sana now? Workday does. That cuts both ways for you: a large, financially stable owner behind the product, and open questions about roadmap and support continuity for the standalone tool you'd be signing for.

What you get today is Enterprise Search across 100+ integrated applications, including Salesforce, SharePoint, Confluence, ServiceNow, Slack, Workday, Jira, Dropbox and the Google suite. Add a Knowledge Assistant for real-time answers and meeting recaps, agents for multi-step automation, live dashboards, contract drafting and RFP responses.

Compliance is thorough: SOC 2 Type 2, ISO 27001, GDPR, SAML SSO, AES-256 with TLS 1.2+, custom roles and audit logging. Strava, Robinhood, Asics, Polestar, Brex, Truecaller, Merck and Electrolux are named customers.

No outside reviewer base is reachable to weigh any of it, so the free tier is where you'd form your own view.

The bill: Free is genuinely $0 but tightly capped at 10 meetings a month, 5 workspace members and 1,000 documents per integration. Team is $30 per user per month for up to 50 members and 10,000 documents per integration. Enterprise is custom, with unlimited members and documents and an MCP client for custom connections.

Ranks 11 to 15: platform buys and suite plays

11. Mindbreeze, above 10 million documents

Is a published six-figure price bad news? For you, it's one of the most useful numbers in this guide. Mindbreeze lists EUR 83,000 per year (USD 103,700) for its xM tier, and that one figure tells you what "contact sales" tends to mean at this end of the market.

InSpire is built for large regulated organizations. You get 490+ ready-to-use connectors, 500+ document, image and video filters, and applied AI services (entity recognition, classification, natural language processing, RAG) included across all tiers.

The certification stack is among the deepest here. SOC 2 Type II under ISAE 3000, audited by PricewaterhouseCoopers GmbH for the period January 1 to December 31, 2025. Plus ISO 27001, ISO 27018, ISO 20000-1, ISAE 3402 Type 2, ISO 9001 and BSI C5.

If your security review is the hard gate, that paperwork is what puts Mindbreeze on your list.

The customer list says who has already walked it. Wells Fargo, Freddie Mac, Deutsche Telekom, Lufthansa and FANUC are named customers, out of a base Mindbreeze puts at 3,000+ worldwide alongside roughly 170 partners.

The bill: four tiers sized by corpus.

1M: up to 1,000,000 documents or information objects. Quote only.
5M: up to 5,000,000 documents or information objects. Quote only.
xM: more than 10,000,000 documents or information objects. Starts at EUR 83,000 per year (USD 103,700).
Infinity: unlimited documents or information objects. Quote only.

No trial, no free tier, so count your documents before you call.

12. Kore.ai, for its conversational stack

Already running Kore.ai for conversational AI? Its Enterprise Search module extends what you have, with agentic RAG over your structured and unstructured data and role-based access enforced at retrieval. You also get a customizable extraction, enrichment and retrieval pipeline, plus multi-vector and multi-modal retrieval.

It ships 100+ pre-built connectors across CRM (Salesforce, Dynamics, SAP), HR (Workday, ADP), ITSM (ServiceNow, Jira), marketing platforms and code repositories. Morgan Stanley, Deutsche Bank, Johnson & Johnson and Pfizer are named customers, and Kore.ai publishes customer results including 74% first-call resolution at one and a 60-agent enterprise deployment at another.

16 PeerSpot reviewers rate it 3.9/5, with 93% willing to recommend it. They value the low-code approach, usable without deep AI expertise, and the Agent Desktop and Co-pilot tooling. For instance, several credit its training programs and certifications for getting teams productive.

The same group reports documentation gaps that force trial-and-error troubleshooting, post-implementation support that lags peers, and Azure scalability limits against a smoother AWS deployment.

You already know whether this one is yours. If Kore.ai runs your conversational stack today, search is an extension you can negotiate into a relationship you have.

If it doesn't, every path on the site leads to a contact form or an RFP, and you'd be starting a full procurement to buy a module.

13. Lucidworks, for extreme query volume

Reddit's search runs on Lucidworks, at up to 301,000 searches per minute at peak. That figure comes from an independent reference entry rather than from Lucidworks itself. If your worry is whether a platform holds up under load, start there.

A deployment like that needs a vendor that sticks around. Nineteen years old, $179 million raised across six rounds, including a $100 million Series F in 2019 led by Francisco Partners and TPG Sixth Street Partners.

The product is Neural Hybrid Search plus RAG, with pre-trained and custom embedding models, query vectorization and generative AI query stages. Around it sits a multi-studio architecture: Commerce Studio, Analytics Studio, UI Studio and Agent Studio. Data enrichment covers summarization, keyword extraction, named-entity recognition and classification.

Connectors number 20+, the smallest published count in this ranking, though a REST V2 connector covers what the list misses. Check your top ten systems against it before you go further.

The Trust Center is where this entry earns its rank. SOC 2 Type 2, issued June 4, 2026. ISO/IEC 27001:2022, issued August 7, 2026. Data Privacy Framework certifications for the EU, Switzerland and the UK, plus CSA STAR, the CISA Secure-by-Design Pledge and a stated 24-hour recovery time objective.

Current, dated, specific: take those dates straight into your security review.

Query volume is what puts Lucidworks on a shortlist. At Reddit scale you buy it and negotiate. Below that, you're paying for headroom you'll never touch, and the pricing URL is a Contact Sales form: no plans, no tiers, no figures.

14. Onyx, the exit route

Want an exit route written into the license? Start here. Onyx is MIT-licensed with 32,000 stars on its GitHub project, which means you can read the code, host it yourself and leave whenever you want.

Connectors number 40+ on the pricing page and 50+ on GitHub, and you choose the model: OpenAI, Anthropic, Gemini, or self-hosted Ollama, LiteLLM and vLLM. The Business plan bundles chat and search, custom agents, web search, deep research, code interpretation and image generation.

Security covers SOC 2 Type II, GDPR compliance, RBAC, permission inheritance and secret encryption, with OIDC and SAML SSO plus on-premises deployment at the Enterprise tier. Ramp is a named customer reporting 30x return on investment, and the vendor says 1,000+ enterprise teams use it as their primary AI interface.

Vendor's own numbers: a 64% win rate against ChatGPT and 68.1% against Claude, across 99 real workplace questions over 220,000 internal documents. That's Onyx's own benchmark, on Onyx's own corpus. Read it as a promise to test, not a result to cite.

The bill: Business is $20 per user per month billed annually, with a free trial and community support. Enterprise is custom.

15. Gemini Enterprise, for Google Cloud shops

Google Cloud's entry is described in its own docs as an intranet search, AI assistant and agentic platform. You get permissions-aware multimodal search, with prebuilt connectors named for Confluence, Jira, Microsoft SharePoint and ServiceNow.

Compliance rides on Google Cloud's program: SOC 2, SOC 3, ISO 27001, ISO 27017, ISO 27018, HIPAA, FedRAMP and PCI DSS. Like the other bundled defaults, it comes with no reachable reviewer base, so your pilot carries the whole burden of proof.

The catch is the edition matrix. Read it before you read the marketing.

Sales handles the price. What's published is the quota table, edition by edition, and it's where your real constraint lives.

Edition	Assistant queries per day	Storage	Agents created per day	Price
Standard	160	30 GiB pooled per user	1	Contact sales
Plus	200	75 GiB pooled per user	10	Contact sales
Business	-	25 GiB pooled	-	Contact sales
Pay-as-you-go	No feature quotas	Billed at $5 per GiB-month	No feature quotas	Usage-based
Frontline Starter and Worker	20 to 40	2 GiB pooled	-	Contact sales

Three conditions to carry into the negotiation. Business covers 1 to 500 users. Pay-as-you-go requires an invoiced Cloud Billing account. And Frontline can't be bought standalone: your organization needs 150 or more Standard or Plus seats first.

Ranks 16 to 21: specialists, and the layer underneath

16. Sinequa, for vast document estates

If your document estate is large enough that procurement wants references at comparable scale, this is the tier of vendor you're shopping in. Sinequa reports 200,000+ users, 400 million documents and 50 billion records under management across its whole install base. Cummins, Pfizer, ExxonMobil, Siemens and Airbus are named customers, and the company is part of ChapsVision.

The retrieval stack is hybrid neural search: keyword plus deep-learning and LLM-based semantic reranking. You get vector, keyword, graph and structured methods, with advanced RAG and agentic orchestration over 200+ pre-built connectors and MCP integration.

Security is thorough. SOC 2 Type II, ISO 27001, HIPAA, GDPR and CCPA, with document-level role-based access control, end-to-end encryption and continuous audit logging. Analysts have noticed too: a Leader placement in the SPARK Matrix Enterprise AI Search Q4 2025 report, and Representative Vendor status in a Gartner Market Guide.

Vendor's own numbers: a commissioned Forrester Total Economic Impact study found 299% ROI, and a Siemens case study reports 30% faster insight discovery. One study, one customer story, both cited by the vendor.

Scale is the whole argument here, and you already know whether you clear it. If your corpus sits in the tens of millions rather than the hundreds, you're overbuying. The only pricing-adjacent page is a form offering a conversation with an expert.

17. Squirro, for on-premises deployments

Wrong fit first. If you want to sign up this afternoon and search by dinner, keep moving. Squirro sells a consultative rollout, puts deployment at 2 to 10 weeks depending on the use case, and frames its own approach as "land small, prove fast, expand".

For a compliance officer in banking, insurance, healthcare or government, the feature list reads like a wish list. A Privacy Layer that avoids storing personally identifiable information. AI Guardrails, role-based access, Knowledge Graphs, a Classifier and an Expert Finder.

Then the paperwork: ISO 27001 certification, GDPR compliance and regular third-party penetration testing, with on-premises deployment when the cloud is off the table for you.

Connectors cover Confluence, SharePoint, Jira, Salesforce, Microsoft Dynamics, ServiceNow and Tableau. The Agent Catalog ships 14 pre-built agents spanning finance, HR, legal, sales, IT and R&D.

Squirro names Henkel as a customer running it with 3,300 users, alongside Siemens, OCBC Bank, Bertelsmann, ZwickRoell and Candriam, and its case study puts one central bank customer's annual savings at EUR 7.2M.

None of that is corroborated by a reachable independent reviewer base, so your 2 to 10 week pilot is the evidence you'll be presenting internally.

Deployment shape decides this one. If regulation puts your data on your own hardware, Squirro belongs on your list, and you'll be asking sales for a figure because the pricing page is a contact form.

18. Hebbia, for finance and legal

Hebbia is the vertical specialist here, and it barely pretends otherwise. Two products: Max, an AI analyst agent that produces spreadsheets, slides and reports, and Matrix, a table-based document-reasoning tool positioned to trace every finding back to its source.

The integrations tell you exactly who it's for. FactSet, S&P Capital IQ, PitchBook, SEC filings and European filings, alongside Salesforce, Snowflake and Databricks.

The company says it has been deploying at top firms for 5 years, has processed 2T+ tokens for investors, and puts its client firms at $30T in assets under management across 1000+ use cases in production. Backing comes from Andreessen Horowitz, Index Ventures, Google Ventures and Peter Thiel.

Security covers SOC 2 Type II and ISO certification, AES-256 at rest, TLS 1.3 in transit and GDPR compliance, and Hebbia states a policy of never training on your data.

Your industry decides this one, and the answer is binary. Investment bank or law firm? Hebbia belongs on your list, and the pricing page routes you to a demo request either way. Manufacturer trying to find HR policies? Skip it.

19. Algolia, the free door

Algolia is search infrastructure with a real free door: 10,000 search requests a month and 50,000 records at $0.

Above that sit NeuralSearch, AI Mode natural-language search, RAG-based generative experiences, Agentic Commerce, and AI Ranking and Personalization. Gartner has named it a Leader in the Magic Quadrant for Search and Product Discovery for three consecutive years through 2026.

Algolia puts its own scale at 1.75+ trillion searches annually for 18,000+ customers across 150+ countries, and cites a Forrester study crediting it with $3.1M in net present value over three years.

Against numbers that big, the reviewer base is tiny. 7 Trustpilot reviewers split sharply on it, and that's a small sample to lean on. They call the interface "super clean and intuitive" and the API easy to integrate.

The same group reports customer support backlogs running weeks. They flag pricing they consider expensive, with undisclosed cost drivers such as crawler traffic counting against limits. They report reliability incidents too, including unexpected disconnections and disappeared indexes.

The bill: four tiers, three of them priced.

Free: $0, with 10,000 search requests a month and 50,000 records.
Grow: pay-as-you-go at $0.50 per 1,000 extra requests and $0.40 per 1,000 extra records, with 100K records included and a 50-index maximum.
Grow Plus: $1.75 per 1,000 extra requests and $0.40 per 1,000 extra records, adding AI Ranking, Advanced Personalization and AI Synonyms.
Elevate: a custom annual contract carrying NeuralSearch, AI Collections, a 99.99% availability SLA and SSO.

20. Dust, a build-it platform

Dust is an agent-building platform, and its search comes from RAG retrieval and structured table queries across your connected systems. So you assemble search here rather than buy it finished.

Its connector list is the reason it earns a place. 25+ native integrations cover Google Drive, Notion, Dropbox, SharePoint, OneDrive, Slack, Microsoft Teams, Gmail, Salesforce, HubSpot, Snowflake, Databricks, BigQuery, Zendesk, Jira, GitHub, Confluence and Power BI. Custom connections run through Zapier, Make.com, n8n and Power Automate.

Beyond retrieval you get reusable "skills", structured output formatting, context compaction for long conversations, knowledge bases and audit logs. Your admins get SSO and role, group and permission-based workspace governance.

Model access is tiered through Basic, Standard and Premium presets that draw on OpenAI, Anthropic, Google and Mistral rather than locking you to one provider.

Appetite for building is what separates a fit from a mistake here. If your team wants to assemble search and agent workflows on top of the SaaS stack you already run, Dust fits. If you want a finished search box on Monday, look higher up the list.

Either way, Dust has no confirmed plan pricing you can carry to finance.

21. Vectara, for hallucination control

Vectara aims squarely at what happens when the answer is confidently wrong. It ships a Hallucination Corrector and an Open Eval Framework for hallucination evaluation, layered into the RAG pipeline rather than bolted alongside it.

Deployment options run from SaaS to customer-managed virtual private cloud, on-premises and air-gapped, with SOC 2 Type II and HIPAA compliance, audit trails and role-based access control. Integration is developer-facing: a REST API, a Python SDK, LangChain and an Airbyte connector.

Broadcom is a named case study, with support-ticket deflection reported rising from 33% to 95%. Those are Vectara's numbers to publish, and no reviewer base was reachable to argue with them.

The bill: six figures before you start. SaaS begins at $100,000 per year, VPC at $250,000 and on-premises at $500,000, each covering one deployment. A 30-day free trial includes all features. There's no permanent free tier.

Nine questions to answer before the first demo

That's all twenty-one, from a $12 seat to six-figure annual floors. Run your shortlist through these. Which one cuts fastest? Number one, every time: a FedRAMP or air-gapped requirement empties most of this list in a single sentence, and the rest of the questions get easier once it has.

Do you have a FedRAMP or air-gapped requirement? If yes, your list starts at Moveworks, Gemini Enterprise on Google Cloud, Microsoft 365 Copilot's government clouds and Vectara's air-gapped option, and most of the rest fall away.
Does your corpus sit inside one suite, or two? One suite, price the bundled route first, but check what "bundled" costs: only Rovo is included in an existing Jira or Confluence subscription, while Copilot is a paid add-on and Gemini Enterprise is quoted separately. Two or more, treat the bundled tool as partial coverage and shortlist a standalone vendor alongside it.
Can finance absorb a metered, usage-variable line item? Rovo bills credits with $0.01 overages, Coveo sells in units of 100,000 queries, Elastic stacks storage and transfer charges, and Glean layers model usage on top of the seat fee.
Do you need a price before the first sales call? Nine publish a number you can work with: Dashworks, GoSearch, Onyx, Sana, Copilot, Rovo, Elastic, Algolia and Vectara. Mindbreeze publishes one of its four tiers and quotes the other three. Ten more route every cost question through sales, and Dust has no confirmed plan pricing to budget from.
Who owns the permissions and SharePoint cleanup, and when does that work start? See the Copilot entry above: Microsoft's own docs put it before deployment, and permission-aware search will expose every access-control mistake your organization has ever made.
Would you deploy self-hosted to keep an exit route? Onyx is MIT-licensed and self-hostable, Vectara offers VPC and on-premises, Squirro offers on-premises, and Lucidworks covers self-hosted Fusion in its SOC 2 scope.
How many connectors do you actually need on day one? Published counts range from Lucidworks' 20+ to Mindbreeze's 490+, several vendors name individual systems instead of a count, and the number that matters is how many of your top ten systems appear on the vendor's list.
Are you willing to buy on vendor-reported figures? Several of the boldest claims here come from the companies selling the products: deflection rising from 33% to 95%, EUR 7.2M in annual savings, 299% ROI, 64% and 68.1% win rates. If that's uncomfortable, weight the eight tools with a public review base more heavily.
Are you buying a product or a roadmap? Moveworks answers to ServiceNow now, Sana to Workday, and Moveworks' reviewers already report that integration is harder for organizations not on ServiceNow. On a multi-year contract, ask who sets the roadmap before you ask what the seat costs.

Frequently asked questions

Is there a genuinely free enterprise search tool, or are they all trials?

Three are real. GoSearch offers a no-credit-card free plan with 10 searches and 3 GoAI queries a day. Sana AI's free tier covers 10 meetings a month, 5 workspace members and 1,000 documents per integration. Algolia's free plan allows 10,000 search requests a month and 50,000 records.

Microsoft's free Copilot Chat (Basic) is included with eligible subscriptions, but it's web data only, with no automatic access to your organizational content.

Everything else is time-boxed. Dashworks runs 14 days without a card, Vectara 30 days, and Coveo, Onyx and Elastic offer trials rather than permanent free plans. Onyx is a separate case, since its MIT license lets you self-host without paying for seats.

Will enterprise search be accurate on day one, or does it need tuning and data cleanup first?

Expect tuning. The tools with the largest review bases say so directly. Guru's reviewers report search accuracy degrading on larger knowledge bases, and Coveo's report relevance that isn't accurate out of the box. Elastic's describe cluster configuration and ongoing shard and replica work, and Dashworks' cite occasional accuracy issues.

Copilot buyers carry a SharePoint cleanup first, per Microsoft's own docs. On timelines, Moveworks reports an 8-week typical time to value, and Squirro describes 2 to 10 week deployments depending on the use case. So budget for the cleanup, and put a relevance owner on the project plan.
