Office & Productivity

Obsidian is a note-taking and personal knowledge management app built around plain markdown files stored locally on your device. Rather than a rigid folder hierarchy, Obsidian encourages a networked structure through bidirectional links, backlinks, and an interactive graph view that visualizes how notes connect. Because notes are just markdown files on disk, Obsidian is fast, works fully offline, and keeps your data portable - there is no proprietary lock-in. A large community plugin ecosystem extends the core app with everything from spaced-repetition flashcards to kanban boards and calendar views. Obsidian Sync and Obsidian Publish are optional paid add-ons for cross-device syncing and publishing notes as a website, but the core app is free for personal use.
