I have something ridiculously overengineered for this. An ios shortcut that you can call on a webpage, that puts the webpage url onto a queue; a worker on my home server pulls these urls from the queue and calls yt-dlp on em, downloading the urls to Plex.

Mainly used for allowing my kids to view some content I can screen for appropriateness, that also gets rid of the ridiculous ads.

A thing yet to do is to use a LLM to automatically categorize these downloads into folders
