Seems okay for short notes. QR code gets a little cut off in Firefox. Seems like you would quickly hit usability limits after a small amount of notes.

You might be able to squeeze more out with a of video-QR codes to sync all notes, but that adds a lot of complexity:

i had a plan to do this to sync all notes , but dropped it as it will take more time, thanks for pointing it out

Hi HN, Paper is a simple tool that i made to easily share small text from mobile to laptop, it converts your text/note to qr code and with the same app in pc, it can transfer the note to pc through camera. it is pwa based and stores data in localstorage. please note that this app wont work for larger character texts.
