Obsidian is a local-first notes app for people who want privacy and speed. Your notes live on your device in open file formats, so you own your data, can work offline, and are never locked in. No one else can read your notes, not even the makers.
It helps you think better by connecting ideas. Create links between notes, visualize relationships with a graph view, and use Canvas for wide-open brainstorming, research maps, and diagrams. Thousands of plugins and themes let you shape the app to match your workflow.
When you need reach and collaboration, Obsidian offers end-to-end encrypted Sync, selective device syncing, version history, and team sharing. With Publish, turn your vault into a fast, customizable site for wikis, docs, or a digital garden.
