I'm not sure it will work with my handwriting. can i order it, do a test (on normal paper, without using the enclosed notebook) and if necessary return it, with complete, intact and complete packaging? does the handwriting digitisation really work? in all languages? do i then have to pay for a subscription to the service? what software/app is needed to digitise notes and then correct them, colour them, highlight them? Does anyone know it? Does anyone use it?
