This gets a transcript for this one https://tactiq.io/tools/run/youtube_transcript?yt=https%3A%2...
Or I tend to just click transcript on the youtube page and copy and paste all into my text editor. It's not a very good transcript though like just the words, not who said what.
Dunno if there's an AI version that's better?
