Obsidian Wiki

Obsidian Wiki: Framework for AI agents to build and maintain a digital memory system through an Obsidian wiki.

Obsidian Wiki is a digital brain that grows with your AI agent by compiling knowledge into interconnected markdown. It works by pointing at a folder and using markdown skills that agents like Claude Code, Cursor, Codex, Windsurf, and Gemini CLI read and run. Users can feed it docs, PDFs, chat exports, meeting transcripts, screenshots, and URLs, then ask questions to receive answers with wikilink citations. The vault is stored as plain markdown on disk with no runtime, API keys, or vendor lock-in required. It is designed for developers and users who want to give their AI agents persistent cross-session memory and fast structural querying. What sets it apart is that it compiles knowledge instead of accumulating it, keeping files clean through built-in linting, deduplication, and atomic writes.
