Knowledge that compounds
Grow a tree of knowledge with your AI
MemTree is a shared knowledge base with a built-in MCP server. Claude and other assistants write structured markdown notes while they work with you, and you read, edit, and connect the same notes in the browser. All of it links into one knowledge graph.
Plain markdown, zero lock-in
Every note is markdown at heart. Observations, tags, and [[wiki links]] become graph structure automatically, export everything, any time.
One tree, many minds
Connect Claude, ChatGPT, Claude Code, or any MCP client. What one assistant learns in conversation, the next can recall, and so can you.
Built for teams
Shared projects with owner, editor, and viewer roles. Full-text search, version history, activity feeds, and public share links.
