Comments about Obsidian as an Alternative to Notion
I like Obsidian as the best Notion alternative because it's totally free, you can use almost every feature of it without paying a dime, and while there are AI user plugins, it's not integrated into Obsidian like it is with Notion.
For what I use these applications, Obsidian would be my go to if they didn’t lock cross device syncing behind a paywall.
Almost everyone thinks Obsidian is a great Notion alternative.
Obsidian is the most popular Windows, Android, Mac & iPhone alternative to Notion.
Obsidian is the most popular free alternative to Notion.
- Obsidian is Freemium and Proprietary

Just an amazing free note-taking app where you own your data. The only issue is it's not open source.
