I'm organizing myself more and more using emacs's org-mode—It's an emacs major mode, it's plain text, it's customizable and extensible like no other thing, it's great, check it out. I try to use concepts from the GTD method, one of which being the capture part of the process: put the ideas or pieces of information into an "inbox" when they come up. But that sometimes happens when I'm not in front of a computer. There are a number of android apps that interact with org-mode files, but for some reason or another, it's never been ideal. Plus, I just want to jot in new headlines in a "inbox.org" file, maybe attach a picture or a vocal note, nothing more. I've wrote something in the past that would listen to incoming emails and add their content to a "inbox.org" file, so I could essentially email stuff directly to my org-mode inbox, but it didn't stick because the resulting program was a bit convoluted and not super reliable.
Enters Deltachat. It's a good decentralized messenger, that has bots which are pretty quick and straightforward to write and host. So I wrote the Deltachat inbox bot. Every message (and its attachments) sent to it are added as a new headline in my inbox org-mode file. The computer that hosts the bot needs to have access to the inbox file of course, which I do using Syncthing. You can check out the bot and its code here:

The ratio of I much code this is to how much I use and rely on it is pretty high. Adding a task on the go has now very low friction: you just write it to the bot's conversation (to which you can set a shortcut on your homescreen).
This is a very niche bot that is useful for the 10 people who live at the intersection between Deltachat and org-mode users. If you happen to be one of them, feel free to try the bot out and send any comment you might have.
