I've got a Boox Note Air and it has AI handwriting recognition of handwritten notes made on the device, next to general handwriting recognition when responding to for example e-mail or writing in apps.
Totally, the reMarkable has handwriting recognition as well — this project was partially borne of the workflow of "write text, auto transcribe, send to a computer, copy paste into an email." How do you like the Boox? My friend loves his!
I love it as well, care it with me everywhere, with termux and a bluetooth keyboard use it as little programming machine and second i make notes, and during a dzogchen teaching yesterday use it to branch into different questions and topics while notetaking with claude sonnet. it's mind expanding, of course I could also use an ipad with apple pen for this, but this has a more natural screen and longer lasting battery.
Android apps are also a killer feature, my phone ran out of battery, so I just listened to podcasts and e-books on the boox.
