Glean Review: AI Enterprise Search That Connects Every Tool Your Team Uses

Glean is an AI-powered enterprise search and knowledge discovery platform that connects all your company tools through a unified search interface, using AI to surface the most relevant information regardless of which application it lives in.

Is it worth using? Yes for any organisation where employees regularly waste time searching across multiple tools or cannot find information they know exists somewhere in the company’s systems. Who should use it? Enterprise teams, knowledge workers, and organisations with complex tool stacks where information is fragmented across many applications. Who should avoid it? Small teams with a simple tool stack of three or fewer applications where basic built-in search across those tools is sufficient.

Quick Summary

Verdict Summary

Organisations wanting to build an AI assistant on top of their actual proprietary knowledge base

Not for

Small teams with simple toolstacks where built-in search within each tool is sufficient
Organisations with strict data sovereignty requirements that prevent connecting tools to a third-party search layer
Startups in early stage without significant accumulated knowledge to search across

Rating ⭐⭐⭐⭐½ 4.7 / 5

What Is Glean?

Glean is an enterprise AI search and knowledge management platform used by hundreds of enterprise customers including major technology, finance, and professional services organisations. It connects to over 100 enterprise applications including Slack, Google Workspace, Microsoft 365, Salesforce, Jira, Confluence, Notion, GitHub, Zendesk, and many others, building a unified search index across all connected tools.

Its AI layer does more than keyword matching. It understands the context of what you are looking for, the relevance of different results to your role and recent activity, and the relationships between documents, conversations, and people across your organisation. The result is an enterprise search experience that genuinely surfaces the right information rather than a list of keyword matches to sift through.

How You.com Works

Connect your tools. Your IT administrator connects Glean to your company’s applications using secure OAuth integrations. Glean indexes content from all connected tools while respecting existing permission structures.
Search across everything from one place. Employees access Glean through the web app, desktop app, or browser extension and search once to find results across all connected tools simultaneously.
Get AI-generated answers. For many queries, Glean goes beyond showing search results to generating a direct AI answer based on information found across your connected tools, citing the sources it used.
Discover people and expertise. Glean surfaces who in your organisation knows about a specific topic based on their activity, documents, and conversations across connected tools.
Use the AI assistant. Glean’s AI assistant can answer questions about your company’s own knowledge, draft documents drawing on existing content, and summarise threads or documents on request.
Receive personalised surfacing. Glean learns your role, team, and recent activity to proactively surface relevant information without you needing to search for it.

Final Recommendation

Glean solves one of the most consistently costly problems in enterprise organisations: employees unable to find information they know exists. For any organisation where knowledge workers regularly waste meaningful time searching across tools or recreating work that already exists somewhere in the system, Glean’s ROI is measurable and often substantial. The platform is worth a serious evaluation for any enterprise with more than 100 employees and more than 10 connected tools in regular use.
