Quickly transferring files between PC and phone - SDF Chatter

Hey, I was wondering what folks use to quickly send a file or a link between your PC and android phone in a self hosted way. Currently I use syncthing to copy files around, but I’m looking for something more immediate, and quick than doesn’t involve searching for folders in a file manager. Example use case: Send a file from PC to phone. Notification pops up on phone, tap it to access. (PC runs OpenBSD) What do you guys use? Stuff I tried so far: - syncthing - xmpp - tox - scp and termux. - magic wormhole - telegram saved messages
