If you aren't opposed to Google, "Keep" seems to be fairly well suited for this kind of thing. You can share to it easily on android, it supports a bunch of organizational things (labels, colors, archiving) but they're not in the way if you want to ignore them, and the browser version works great. If you're attached to the chat style, then it might not be perfect, but it's easy to use it as a continually appended log style experience.
Thank you! I can really relate to that habit. Unfortunately, I haven’t started working on an Android version yet, so it doesn’t seem likely to be available soon. Sorry about that.
I abuse the telegram "Saved" channel to send myself thoughts, notes, reminders, pics, etc as if I'm chatting to the me who's back at his desk.
I wanted to get away from that and not rely on telegram.
Unfortunately I'm an android user so I'll probably have to keep using Telegram for the time being. Is there an android client in the works?
