My weirdest idea for this kind of transfer is to have it transmitted through high-frequency soundwave, and there would be a PSK modulator on the sending side and a matching demodulator on the receiving side. Making one would probably be a project too complex to manage, especially since I don’t know how you would demodulate PSK in the first place
Then I realized JAB Codes exists so I use that now (though it would be better if I didn’t have to open a browser to make one)
I’ve yet to find something I can use to transfer text (and just text) from my phone to my laptop without the struggle (and memory) of making a file and moving it to my laptop
Bonus points if it’s all local and I don’t have to transfer it through “the cloud”
