An important part of the Youtube content is the transcript at the bottom of the video description. There are some 3rd-party sites that collect and share the YT transcripts separately but then the naive admins put the service in Cloudflare’s walled garden, which is worse than YT itself and purpose-defeating to a large extent. (exceptionally this service is CF-free, but it says “Transcript is disabled on this video” in my test: https://youtubetranscript.io/)

Invidious should be picking up the slack here.

And Lemmy could do better by automatically fetching the transcript of youtube/invidious links and include it, perhaps spoiler style like this.
