We built Kumbukum because team knowledge keeps getting scattered across chats, notes, URLs, and AI tools. Kumbukum is an open-source memory infrastructure for teams: a shared layer for notes, memories, URLs, and reusable context that remains inspectable and portable. Add and manage everything in the app or MCP server. Plus, add URLs and notes with a browser extension. Happy to answer questions.
