Thanks, I was only aware of being able to download auto subtitles from yt-dlp and downloading description into a text file. Is it possible to download comments too? Depending on what kind of video you watch, like if you are watching a video about grammar on foreign languages, sometimes there are people giving good advices in approaching it in a more simplistic way or easier to remember.

e: apparently there’s --write-comments for that to save into a json file

I am aware of there existing desktop-first open-source like PrimeOS and fydeOS for low-end computer/notebook but since it’d only be used for that I don’t think it’d be worthy having an extra device exclusively for that, if I end up having another use cases restricted to Android maybe I’d have the more reasons to try such approach. I’ll sure keep it in mind though, I really appreciate your suggestion, thank you!

Thanks, pinchflat might help!

Thanks. Is there a self-hosting PWA for Grayjay?

TIL of TubeSync, thanks, I’m looking into it!

Thank you for clarifying

A web browser which puts everything in a cache, so you can continue to read, if offline.

Ceno does that but it’s for mobile

Maybe I misunderstood but what OP means (that I understood) are softwares that you don’t need to rely on internet connection to use it, probably ones you need 0 need at all of internet connection but I assume OP may also be accepting suggestion of ones you can open while without internet connection but also be able to download data for offline use (maybe like Language Transfer).

For language learning there’s Language Transfer (it’s also open source)
