Open source and BYO API key is the right approach. Getting transcripts and AI summaries right inside YouTube without leaving the page is super convenient for research.

No idea why YouTube hasn’t provided this within the app yet.

@sudshekharapps exactly a multi billions dollar company can’t seem to do that. Let alone have an option to provide feature update requests ..
