Octobrain

Octobrain is a persistent memory and knowledge management system for AI assistants, enabling them to retain and retrieve insights, architecture decisions, bug fixes, and other knowledge across sessions. It offers advanced semantic and hybrid search capabilities, automatic memory linking (Zettelkasten-style), and can ingest and index web content, documents, and files for effective retrieval. Octobrain can run as a command-line tool or an MCP server, allowing seamless integration with Claude Desktop and other MCP-compatible tools, making it suitable for developers, technical teams, and users wanting context-rich, long-term AI memory.
