There are many commercial YouTube summarizers, but I couldn't find an open-source one that truly fit my needs. So, I built YouTubeTLDR: a simple, self-hostable solution that uses the Gemini API without much bloat.

I went with a synchronous approach + threading which was a nice break from Tokio.

It is Bring Your Own Key, but the key is sent to the server for each request, which is something I might revise in the future.

There is a demo on https://youtubetldr.onrender.com/
