FYI if you have a video you can't be bothered watching but would like to know the details you have 2 options that I use (and others, of course):

1. Throw the video into notebooklm - it gives transcripts of all youtube videos (AFAIK) - go to sources on teh left and press the arrow key. Ask notbookelm to give you a summary, discuss anything etc.

2. Noticed that youtube now has a little Diamond icon and "Ask" next to it between the Share icon and Save icon. This brings up gemini and you can ask questions about the video (it has no internet access). This may be premium only. I still prefer Claude for general queries over Gemini.
