Congratulations!
I created an "Augmented Layer" on YouTube called CASCDRVision which allows you to get transcripts and do different kinds of analysis on videos. We allow users to summarize videos, obtain & search the transcript, highlight text to create clips and even use AI to search for top quotes or "fuzzy search".
All of these are lightning enabled services. Happy to collaborate with you to make those available in your application. DM me on nostr if interested and we could work out a plan (video demo links to our profile).
