Choose Glean if
Large companies with knowledge spread across dozens of SaaS tools that need permission-safe AI search and assistants.
- Among the most mature permission-aware enterprise search products
- Very broad connector library including code and ticketing tools
- Model-agnostic, so companies are not tied to one AI vendor
Look elsewhere if: Small teams or firms already standardized on one suite's AI (Microsoft 365 Copilot, ChatGPT Enterprise or Notion AI are simpler).
