How it works
The app is endlessly customisable through community plugins: daily notes, spaced repetition, kanban boards, calendars, and more. Because your notes are local files, they work offline, last forever, and are never locked into a proprietary format.
Obsidian is free for personal use, with optional Sync at $4 a month on annual billing. It is a favourite of writers, researchers, and knowledge workers who want a private, permanent home for their thinking.
