I made a telegram bot for my mother that takes yt urls and downloads stuff to my jellyfin directory so she can download it from jellyfin. She downloaded like 2 tb of audio books the last 3 years.

First I had a simple script. Now I use a little more complex approach with queuing, mqtt and direct replies with wormhole codes so one can download it directly.
