It does a pretty good job. But to be honest I don't use that feature often. I also have the keyboard for it but don't use that often, either. I really mainly use it as a notebook.

I don't know about reMarkable but LLMs are good at recognizing handwriting from photos. I wrote an iOS app to do this for my handwritten diaries, but it works for any handwritten paper: https://inksightful.app/
