Glean is a work AI platform that builds a unified search index across every tool in your company: Slack, Google Drive, Confluence, Salesforce, Jira, GitHub, and 100+ others. Ask a natural language question and Glean retrieves relevant documents, conversations, and data from wherever they live, then summarizes an answer with source citations. Beyond search, Glean includes an AI assistant that can act on company knowledge: draft emails grounded in your CRM data, summarize a project's Slack history, or pull competitive intel from your internal wiki. It also generates knowledge graphs of your organization to surface who knows what and how information flows between teams. Glean is used primarily by enterprises (500+ employees) and has raised over $1 billion in funding at a $4.6 billion valuation. The setup requires an IT admin to connect your apps via OAuth, and personalization improves over time as Glean learns what's relevant to each employee's role.

What the community says

Glean gets consistently strong reviews from enterprise IT admins and knowledge workers who say it solves the 'search across everything' problem better than anything else at scale. Employees at large tech companies praise the cross-app recall and the fact that results improve over time. Common complaints focus on the high price (enterprise-only contracts, no SMB tier) and the setup complexity that requires IT involvement. Some users note that search quality depends heavily on how well your apps are indexed, which can vary.
