This is wonderful. I made questionyoutube.com yesterday to solve a similar problem, I think this is better in the limit though.

If you can just get search time down, and make the summarization a little better, that would be amazing.

For instance, I tried this with 'what Toyotas should I avoid' and it found good relevant videos, but in the summary of 'Bad Toyotas you need to avoid' it misses that certain Toyotas from 2007-2009 had an oil burning issue, which was the main topic of the video. Querying the transcript of the video with 'what Toyotas do I need to avoid' gives a more complete answer. I'm curious how your handling the initial summary.
