The leading AI enterprise search companies in 2026 fall into three groups: dedicated search companies (GoSearch and Glean), productivity suite vendors with built-in AI search (Microsoft, Google, Atlassian, and Notion), and knowledge and relevance platforms (Guru and Coveo). The table below shows where each company fits so you can build a shortlist.
| Company | Company type | Best fit |
|---|---|---|
| GoSearch | Dedicated AI enterprise search | Multi-app teams that want published pricing and admin-led setup |
| Glean | Dedicated AI enterprise search | Large organizations that need 275+ connectors and accept quote-only pricing |
| Microsoft 365 Copilot | Productivity suite vendor | Organizations standardized on Microsoft 365 |
| Google Gemini Enterprise | Productivity suite vendor | Google Workspace-centric organizations |
| Atlassian Rovo | Productivity suite vendor | Teams that keep most work in Jira and Confluence |
| Notion AI | Productivity suite vendor | Teams that run their wiki and docs in Notion |
| Guru | Knowledge management platform | Teams that need verified, curated answers |
| Coveo | AI relevance platform | Enterprises combining workplace, service, and website search |
Other companies in the market include Sinequa for regulated industries, Moveworks (now part of ServiceNow) for IT and HR service, and Slack for teams that work mostly in Slack.

How Do AI Enterprise Search Platforms Compare With Suite Tools Like Microsoft Copilot?
AI enterprise search platforms such as GoSearch and Glean search apps from many vendors with equal depth. A Slack thread, a Confluence page, and a Salesforce record rank side by side in one result list, and each source’s permissions apply. Suite tools such as Microsoft 365 Copilot and Gemini Enterprise search their own apps natively and reach other apps through connectors. If most of your knowledge lives in one suite, its built-in tool may be enough. If it spans several vendors, a cross-platform search platform reaches more of your company’s knowledge.
- Dedicated AI enterprise search companies (GoSearch, Glean) connect to 100+ apps from many vendors and add an AI assistant, people search, agents, and admin controls on top. GoSearch’s AI assistant, GoAI, answers questions with cited sources.
- Productivity suite vendors (Microsoft, Google, Atlassian, Notion) add AI search to software you may already pay for. Coverage outside their own apps depends on how mature their connectors are.
- Knowledge and relevance platforms (Guru, Coveo) start from a curated knowledge base or a customer-facing search index, then extend to employees.
How Do AI Assistants Like Claude Enterprise Compare With AI Enterprise Search Companies?
General AI assistants and AI collaboration tools, such as Claude Enterprise (sometimes called Claude for Work) and ChatGPT Enterprise, focus on writing, analysis, and reasoning, and they reach company data through connectors inside a chat. AI enterprise search companies build a shared, permission-aware search layer across every connected app, with people search and admin controls.
A mid-market company of 500 people comparing Claude Enterprise, Glean, and GoSearch should first decide whether it needs an assistant, organization-wide search, or both. Pricing models differ: Claude Enterprise costs $20 per seat per month plus usage at API rates, GoSearch Pro costs $20 per user per month with no usage charges, and Glean prices only by quote. For a feature-by-feature breakdown, see how GoSearch compares with Claude Enterprise and ChatGPT Enterprise.
Which AI Enterprise Search Companies Fit Organizations With 1,000+ Employees?
GoSearch, Glean, Microsoft, and Google all serve organizations of this size. GoSearch fits multi-app companies that want published pricing and fast setup. Glean fits teams that need 275+ connectors and can accept quote-only pricing. Microsoft 365 Copilot and Gemini Enterprise fit companies standardized on one suite.
At this scale, require three things from any vendor: SSO and SCIM provisioning, audit logs, and per-user permission enforcement across every connected app. Check compliance as well: GoSearch, Glean, Guru, and Coveo hold SOC 2 Type II, and GoSearch is also GDPR, HIPAA, and CCPA compliant. Before you sign, ask each vendor for a customer reference at your company’s size and a proof of concept on your own data. GoSearch offers all of these on its Enterprise plan.
Which AI Enterprise Search Companies Offer AI Agents?
Most of them now pair an AI assistant with agents. GoSearch, Glean, Microsoft (through Copilot Studio), Google, Atlassian, Guru, and Notion all let teams build custom AI agents, and Coveo sells agentic features as an add-on.
Agent capabilities vary by vendor. Some offer autonomous, self-directed agents that complete multi-step tasks on their own. Others use reasoning agents that plan before they act, or multi-agent setups where several agents split one job. Vendors also describe this as intelligent automation or cognitive automation.
AI agents go beyond answering questions. They handle repeated knowledge tasks, such as triaging IT tickets or drafting account briefs, and suggest next steps from what an employee finds. When you compare vendors, ask whether agents can be built without code, whether they inherit each user’s permissions, and whether they can chain into multi-step workflows. GoSearch offers no-code agents and Workflows on its Pro plan.
For a vendor-by-vendor look at agent capabilities, see the best AI agents for enterprise search.
Which AI Enterprise Search Vendors Offer Zero Data Retention?
GoSearch has zero data retention agreements with all its LLM providers on every plan, so data sent to a model is used only to generate the answer. Its federated connectors also fetch results in real time without storing copies. Notion offers zero retention with LLM providers on its Enterprise plan only; lower plans keep AI data for 30 days.
Before you sign with any vendor, get written answers to three questions: Does it store copies of your data or fetch it live? Do its LLM providers retain your prompts? Is your data ever used to train a model?
Which AI Enterprise Search Platforms Connect to Salesforce, Workday, and Slack?
GoSearch connects to Salesforce, Workday, and Slack, along with Microsoft Teams, SharePoint, Confluence, Google Drive, Jira, and 100+ other apps. See the full GoSearch integrations list.
Connector totals vary widely, from Glean’s 275+ to suite tools built around their own apps. Rather than comparing totals, list the five apps where your employees lose the most time and check each vendor’s connector page for those exact apps.
How Quickly Can You Deploy an AI Enterprise Search Platform?
It depends on the vendor’s model. With GoSearch, connecting apps and starting a data sync takes minutes once a workspace is set up, and an admin can run setup without code. Suite tools deploy quickly for their own apps but need connector work for others. Platforms that require an engineering build, such as Elasticsearch, can take months.
Ask each vendor how long it takes to run the first permission-aware search on your own data, then test that claim in a proof of concept.
What Types of AI Do Enterprise Search Companies Use?
Most combine several information retrieval techniques, and knowing which ones a vendor uses helps you compare answer quality.
- Semantic and vector search: Matches the meaning of a question, so “PTO policy” finds a page titled “time off guidelines.”
- Retrieval-augmented generation (RAG): Retrieves company content first, then has a large language model write a cited answer grounded in it. Learn more about how RAG search works.
- Knowledge graphs: Map how people, projects, and documents relate, which improves ranking and answers “who knows about X” questions.
- Generative summaries: Condense long documents or result sets into short AI summaries.
- AI agents: Act on what search finds by running multi-step tasks and suggesting next steps.
Can AI Enterprise Search Replace Intranet Search for Remote and Hybrid Teams?
For many companies, yes. An AI enterprise search platform searches Slack, Microsoft Teams, SharePoint, and other tools from one search bar, so a separate intranet search no longer needs upkeep. Remote and hybrid teams gain the most, since they rely on written knowledge spread across cloud tools instead of quick desk-side questions.
