Love that it uses my own key and skips the server stuff. One thing that would make it way more useful for me is timestamped chapters that link back to the exact moment in the video, so I can jump straight to the part a summary point came from.

@meryemuzuno5kq Thanks for the idea! I’ll check whether we can extract timestamps alongside the transcript, which would allow the summary to reference and justify itself with the relevant parts of the video.

One thing I'd love is the ability to compare summaries from two different models side by side, so I can quickly see which one pulls out better insights for the same video without having to switch tabs.

@iozamaratl92Thanks for the suggestion! I have a couple of questions:
Do you see this as something that should be behind a feature toggle? I imagine many users will only have one API key configured, and even those with multiple providers may not want to compare summaries for every video.
Would you expect both summaries to be generated automatically in one click, or would you prefer selecting a second model only when you want to compare?
