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).
Choose Living Brain if
Developers and AI-heavy teams who use several models and agents and want one portable memory layer behind them.
- Model-independent memory that follows you across AI tools
- Pay-as-you-go API with a $5 minimum and no subscription
- Many access routes: API, SDKs, CLI and MCP
Look elsewhere if: Teams that just need a note-taking app or a proven enterprise knowledge platform (Notion, Obsidian, Context Engine).
