files.md is a free, open source, local-first note-taking and life management app that stores everything as plain Markdown files, usable directly in a browser via app.files.md.

It supports notes, documents, journals, habits, checklists, and tasks with predefined folder structure, hotkeys, offline use, simple deployment, and optional sync via a single server binary or cloud storage. The project emphasizes thinking over complex “second brain” systems, encouraging simple, linked notes to deepen understanding rather than deferring thought.
