Glean's $7B valuation in 2024 set the price for enterprise AI search, and the rest of the knowledge-management market is now organizing around it. Notion AI is the dominant cross-functional workspace play with $343M raised; Sana Labs targets organizational learning and internal training at $73M. Mem and Coda push self-organizing personal and team workspaces, while Mintlify owns AI-ready documentation for developer products. Pylon brings the same pattern to B2B support knowledge bases. Dosu and DeepJudge specialize in autocapture from engineering and legal workflows respectively. Buyers compare on connector breadth (Slack, Drive, Notion, Confluence, Salesforce), permission-aware retrieval, and whether the answers cite sources cleanly.

FAQ
Frequently asked
Glean vs Notion AI vs Microsoft Copilot for enterprise search?
Glean is the standalone search layer for companies with 50+ SaaS apps and strict ACL needs. Notion AI is best when Notion is already the workspace. Microsoft Copilot wins inside Microsoft 365-heavy environments but lags Glean on third-party connector depth.
How do AI knowledge tools handle source-of-truth conflicts?
Best-in-class tools surface conflicting answers with timestamps and authors, rather than picking one. Glean and Mem both expose source documents inline. Buyers should test with intentionally contradictory documents during proof-of-concept to see how each system reasons across stale and fresh content.
Is llms.txt actually being adopted by knowledge-base vendors?
Mintlify auto-generates llms.txt for hosted docs, and several developer-tool companies publish it manually. Adoption inside corporate intranets is still early. Expect it to become standard for public docs in 2026 and for internal vector-indexed wikis to keep using their existing connectors.
