My wife often writes groceries lists using her phones note app, and sends it to me if I’m doing the shopping. Each item in the list is in it’s own line.

I use Nextcloud Notes, I’m pedantic and want to use a markdown checkist for shopping lists (also bad at shopping). I wrote a Matrix bot, or rather added a feature to an existing one, that adds - [ ] in the beginning of each line of a received message and sends the result back. I then copy-paste the response into NC notes.
