I haven’t come across a FOSS scanner app that comes close to the performance abd features of the popular closed source ones. That’s why I use closed source ones that still work when I deny them internet access. Genius Scan and Microsoft Lens both work that way.

I’ve been using it for a while as well. I often put concert tickets and stuff like that there

If you haven’t used Linux before, just know that Garuda might not be the most stable. It wasn’t for me at least, I had to rescue it often. But that might have been because I didn’t use/update it regularly enough.
