Second brain, shared brain builder and memory layer for AI agents. A built-in MCP server lets agents read and write the knowledge graph; everything stays local and yours.
- Local-first, plain Markdown
- Shared Brain for teams

How it works in 3 steps
- Your notes and sources become a local, private knowledge graph in plain Markdown.
- A built-in MCP server lets your AI agents read and write that graph during live sessions.
- Shared Brain merges attributed contributions from a team into one collective wiki.
