My go to way of taking notes is sending messages to myself. Previously with Signal’s “Note to self” and now with my own channel with Element. It is fast way of taking notes, but horrible in long run since you cannot group notes or add tags or anything else that you would expect from good note taking tool. I have Nextcloud notes, but I still do it since I am used to it and it is fast way of syncing notes with mobile and PC. Anyone else has interesting ways of keeping notes?
If you are interested try Localsend, its even less effort than sharing via a messenger and its peer to peer. You can enable auto downloads for trusted peers then it will be sent directly to a folder of your choice once you send from your phone.
