Show HN: Visual AI Tutoring in the Browser

https://useknowable.ai/
2•samuelzxu•54m ago
Been working on this full-time for a few months now. It's an AI tutoring application that takes in context on your page via Desk View, and responds like a real tutor would.

It only works in Safari on 2022+ Macbook Pros or 2023+ Macbook Airs. Very particular hardware requirements because it's a new kind of product.

Feedback welcome!
