Sometime i want to send small messages between devices, such as a url, a note, a id, a token, a piece of code, a picture Especially send between phone and laptop.

Some chatting app have self messages such as telegram saved messages, slack (you), Microsoft team...

However i don't want a bloated chat app that would took few hundred mb on phone, or required to install an app on my pc (linux which make many app broken). I don't want work chat app too, because self messages can be seen and scanned by employer (yes, a security add on chatbot on slack warm me because i send something like password to myself on slack)

Something like Opera Flow would fit perfectly, but i don't want opera browser.
