What it does
AI assistants such as Claude Code, Codex and Gemini usually forget everything when a session ends. This project connects them to Obsidian, a note-taking app, so they can save and recall information as plain text notes in your vault (your folder of notes).
It adds dozens of commands. For example, one saves the people, decisions and tasks from a conversation into the right notes, one searches your notes, and one turns voice memos, photos, documents or videos into notes. Its makers say new sources update existing pages rather than just adding new ones, and that scheduled agents can tidy and summarise the vault overnight.
A feature called Crew lets several AI tools (Claude Code, Codex, Cursor and Grok Bot) share one logbook in any folder, so each knows what the others did. Some research commands use online services like Perplexity and Grok.
Who it's for
People who already use Obsidian and AI command-line assistants like Claude Code or Codex and want those assistants to remember past work. The makers mention developers, founders, writers and researchers.
