InfinityDB

InfinityDB is an open-source neurosymbolic memory engine for AI agents that runs locally on SQLite WAL mode. Unlike vector memory that relies on costly LLM extraction, InfinityDB provides sub-5ms hybrid recall, deterministic $0 fact extraction, dynamic persona conflict resolution, and SHA-256 audit proofs. Cuts agent prompt token overhead by 81.4%. Compatible with Python (PyPI), Node.js (NPM), LangChain, CrewAI, and Model Context Protocol (MCP) for Claude Desktop and Cursor.
