1. Only on programming.dev, at least in the beginning, but it will be open source so anyone will be able to host it for themselves.
2. I set up a hard limit of 100 summaries per day to limit costs. This way it won’t go over $20/month. I hope I will be able to increase it later.

Thank you, that’s a reasonable suggestion, I added it to the comment template:

TL;DR: (AI-generated 🤖)

It doesn’t work yet, the screenshots are from a private test instance.

It is definitely possible, at least for videos that have a transcript. There are tools to download the transcript which can be fed into an LLM to be summarized.

I tried it here with excellent results: https://programming.dev/post/158037 - see the post description!

I used GPT-4 for this post, which is miles ahead of GPT-3.5, but it would be prohibitively expensive (for me) to use it for a publicly available bot. I also asked it to generate a longer summary with subheadings instead of a TLDR.

The real question is if it is legal to programmatically download video transcripts this way. But theoretically it is entire possible, even easy.
