It’s coming along nicely, I hope I’ll be able to release it in the next few days.

How It Works:
I am a bot that generates summaries of Lemmy comments and posts.
- Just mention me in a comment or post, and I will generate a summary for you.
- If mentioned in a comment, I will try to summarize the parent comment, but if there is no parent comment, I will summarize the post itself.
- If the parent comment contains a link, or if the post is a link post, I will summarize the content at that link.
- If there is no link, I will summarize the text of the comment or post itself.

Prompt Injection:
Of course it’s really easy (but mostly harmless) to break it using prompt injection:
It will only be available in communities that explicitly allow it. I hope it will be useful, I’m generally very satisfied with the quality of the summaries.
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.
Ah yeah looks good. I mean V4 is definitely better, but if someone could write a bot for the V3.5 version it would still be better than nothing I guess.
For videos without transcriptions you could also use whisper to transcribe the videos first. But that would probably be way to expensive and all.
Still nice to see it would be possible.
Yes, I also realized Whisper could be used for this (see sibling comments, I guess they didn’t show up in your inbox).
Oh, I’ve just realized that it’s also possible if the video doesn’t have a transcript. You can download the audio and feed it into OpenAI Whisper (which is currently the best available audio transcription model), and pass the transcript to the LLM. And Whisper isn’t even too expensive.
Not sure about the legality of it though.
If you want it to be really good, you can transcribe the audio even if the YouTube video already has a transcript. Whisper is much better than whatever YouTube uses for the subtitles. Of course it will be more expensive this way.
