FAQ

What is the best free AI note-taking app?

Notion has a solid free tier with basic AI features. Obsidian is free for personal use, and with free AI plugins, it’s the most powerful free option (though you’ll need API keys for advanced AI features).

Is Notion AI worth paying for?

If you already use Notion and attend multiple meetings per week, Notion AI pays for itself quickly. The Q&A feature alone, which lets you ask questions across your entire workspace, saves hours of searching weekly.

Can AI note-taking apps replace human note-takers?

For routine meetings and straightforward information capture, yes. For complex strategic discussions where nuance matters, AI works best as a supplement to human judgment, not a replacement.

Which AI note-taking app is best for students?

Notion AI offers an education discount and has great features for organizing course notes. Obsidian with AI plugins is excellent for research-heavy work. Both allow you to build a connected knowledge graph across multiple courses.

How does Rewind protect my privacy?

Rewind processes all recordings locally on your device. Data never leaves your computer unless you explicitly share it. You can exclude specific apps, websites, and time periods from recording, giving you granular privacy control.
