I think there's a lot of opportunity in this space with AI. It'd be interesting if you could take some metadata into account when organizing notes. For example, you might be able to guess when someone is home when they're accessing the site from a frequent IP address. This example is top of mind for me, as I just completed a move this weekend. I wish I had been better organized taking notes as I set up different home systems in the past, as it's now been a few years and I wish I had notes I could go look back on. Being able to filter my apple notes app by geolocation would be awesome.

I love the idea of not having to worry about tags to keep notes organized. Nice work!
