FYI for others - it works but the extension button doesn't give any feedback (no confirmation messages, no change of colour/appearance, no sound) so it isn't clear that it's worked. You just click the button while the transcript section is open, and then the transcript has been copied. Does what it says it does, thank you for making this :)

It works but instructions aren't clear from the start

no sirve

Does the job, thank you. I was able to turn off the time stamp.

The copy of transcript automatically has the time-stamp even when you toggle time stamp off in the transcript area. It should not copy the time stamp if it has been disabled.

Fonctionne bien. Il a extrait le texte de la video et l'a copié dans le press papier
