Note-taking apps compared: prices and price hikes
Note-taking and personal knowledge apps for capturing ideas, organizing research and building a second brain, compared on what it costs to sync your notes and add AI, and on how each app links, searches and protects what you write.
Prices at 1 user with synced notes
- Microsoft OneNote: free · last hike Jan 2025
- Obsidian: $10/mo
- Evernote: $24.99/mo · last hike Sep 2025
Prices are for one person on monthly billing (annual-only plans divided by 12): the cheapest plan that keeps about 2,000 notes synced between a computer and a phone with no caps, and the cheapest plan that also includes the app's own AI. A free plan counts as $0 only when it covers the scenario without note, device, upload or storage caps.
