i want to move away from using discord as a place to store and organise all kinds of links, text and images. its just come to me how easily i could lose access to it, not just by being offline.
ideally, said program has to:
-work offline
-have android and pc support, especially linux.
-have ability to export data into easily viewable formats
if something satisfies most but not all requirements, please still write about it, it can still be useful.
I use syncthing + Joplin for this. I haven’t looked into exporting data but I’d be surprised if it couldn’t. Otherwise it checks your boxes. Joplin also supports encryption, which wasn’t on your list but is a great feature.
Joplin supports a handful of sync methods but using a file based sync with syncthing is nice because it’s less effort and maintenance to run than self hosting nextcloud, for example. And since it’s purpose is to sync as opposed to remote access, you still have access to a copy your data even if you can’t reach any of your syncthing nodes for whatever reason. Though to be fair you can do that with nextcloud as well.
