"You can summarize many types of web content, including:

Text web pages, articles, and forum threads PDF documents PowerPoint documents (.pptx) Audio files (mp3/wav) YouTube URLs"...

It doesn't actually state video, do you know if it's summarizing the actual YouTube video, or the subtitles?

Whilst they may seem the same, I can see the former being able to be refined over time based on e.g. in scene visual context

It appears to summarize the subtitles alone. I asked it to summarize a video that didn’t have subtitles (silent film) and it refused.

Edit: I missed some of the context, comment above is re you-tldr, not kagi which I haven’t tried.

if it is based solely on subtitles it would seem that those with conversations between characters would get very confusing summaries.
