This is a desktop application for managing Markdown knowledge bases. Each knowledge base is a Git repository, naturally having version history and change records. Notes are stored as Markdown files and can be migrated at any time. It also has a built-in MCP server, supporting AI tools such as Claude Code and Codex to directly read from and write to the knowledge base. It is suitable for building personal second brains, accumulating team documents, or serving as the long-term memory base for AI assistants.
