LangChain introduced OpenWiki Brains, a framework that lets agents build proactive memory by connecting to sources such as Gmail, Notion, and git repositories. The system generates and maintains a local Markdown-based wiki that agents can reference, automatically pulling in relevant context rather than relying solely on reactive built-in memory. It ships with two initial modes, a Personal Brain for general work context and a Code Brain for repository documentation, with plans to add further connectors and full-text and semantic search.
