Obsidian
Obsidian gives away the whole app, keeps your notes as plain Markdown files on your own device, and lets thousands of community plugins bend it to any workflow. It asks for patience in return: setup is confusing, there is no web app and no built-in AI, and collaboration needs paid Sync or third-party tools.
- Plain-text Markdown files open in any editor, which lowers lock-in risk
- Stores notes locally and works offline, so it is fast and private
- Confusing onboarding (vault creation) and a steep learning curve
- No built-in AI, and collaboration depends on third-party tools
