Project overview
second-brain stores notes, relationships, and distilled long-term memories as readable Markdown, with a rebuildable SQLite cache for full-text and graph queries. Use it as a Claude Code skill for capture and proactive recall, or run its zero-dependency MCP server so other clients can read and write the same data. It requires Python 3.8 or later, supports Git-based sync, and is intended for personal-scale knowledge rather than massive document collections or team wikis.
