IWE: An Open-Source Markdown Knowledge Graph for AI Agent Memory

tom_doerr · x · 2026-08-10

IWE is an open-source local knowledge management and AI memory tool that transforms directories of Markdown files into a queryable knowledge graph.

It allows users to perform database-style queries on their notes (e.g., "all accepted decisions in Q1") via an editor or command line. IWE operates entirely locally without relying on the cloud or a separate database, and all files can be version-controlled with Git.

Furthermore, the tool natively supports the Model Context Protocol (MCP), allowing it to act as a memory layer for external AI agents like Claude and Gemini to navigate and retrieve local knowledge.
