Hi Brad, the site is down right now but this looks really interesting.

From the video, it seems like you are also using some visual recognition to match the correct answers on the scan. How are you doing this?

Are you calibrating the position of the sheets with some markers or are you expecting specific coordinates? Is there some AI involved? How accurate is your technique with real-life students filling in the boxes?

Is there some way to correct individual answers (and is there some feedback mechanism involved to do better next time)?

Anyway, congrats on shipping, looks super interesting!
