Cairn Drive
A drive your AI agents can find things in.
Cairn stores your files, indexes them by meaning, project and history, and stays connected to the myAI brain. An agent asks “where’s the signed SOW?” and gets the path back, without anyone telling it where to look.
Pre-release. macOS, Windows and Linux. One program, no Docker, no runtime.
Find
Full-text search over names, paths, tags and the text inside documents, code and PDFs.

Ask where
Ask in plain words and get the path back.
