Show HN: Knowable, the AI tutor that follows your work on paper

https://knowable.ca/
1•samuelzxu•1h ago
I'm building the AI tutor that I wish I had when I was a kid. It's capable of following your thought process through the MacOS webcam as you do rough work and propose meaningful hints. You can download it on the Mac App Store for free, and use the free version without signing up for a free trial of a paid version.

Open sourced - note, readme's are out of date.

Ping me at `samuel at knowable dot ca` for suggestions and feedback!
