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

A developer has released Knowable, a free AI tutor for MacOS that uses the webcam to follow a student's handwritten work on paper and provide contextual hints. The application is available on the Mac App Store without requiring sign-up or payment, and its code has been open-sourced on GitHub.

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Open sourced - note, readme's are out of date.
