Kumbukum is an open-source, team-shared memory layer that connects your notes, decisions, emails, links, and Git context to Claude, Cursor, ChatGPT, and any MCP-compatible tool.
Kumbukum fills a real gap: AI tools forget everything between sessions, and teams waste time re-explaining context. If your team uses Claude, Cursor, or ChatGPT heavily, a shared memory layer that works across all of them is genuinely useful. Self-hosting is free; what you pay for cloud access is unclear until you sign up.
One shared library — notes, memories, URLs, emails, decisions, Git threads — readable and writable by any MCP tool your team uses
44 MCP tools connect it to Claude Desktop, Cursor, ChatGPT, Windsurf, Zed, VS Code, and more in one integration
Email Command Center triages incoming email against your team's knowledge and drafts replies that sound like your team
Self-hostable under AGPL-3.0 with zero per-user fees; 400+ commits and 31 public releases
