Monolithos is a personal AI app that stores its memory as Markdown and YAML files you can inspect, edit and take with you. The current release includes conversational recall that cites its sources, plus modules for task orchestration, capture, meeting records, writing, Markdown-to-slide decks, audio briefs and a visual library. It is available for macOS, Windows and iOS, and works with Obsidian vaults.
Monolithos is built around the idea that your AI memory should live in files you own. The team says a fuller personal agent is still in development.
