I have tried Anytype, and I think the whole sets approach to databases as well as their version of the graph is pretty innovative. However, it just isn’t as robust as Notion or Obsidian yet, so I haven’t used it for anything. I tried to use it for school, but Obsidian was just so much more convenient, so I went with it instead.
I want to like it, I think it’s cool and innovative, but right now I think Obsidian wins. Everything Anytype does exists in Obsidian already as a core feature or plugin. There’s even a sets plugin based on Anytype being reviewed for community plugins right now.
