Every week I build an app with a random coding tool – a wheel picks it, and I have to use whatever it lands on. This week: a YouTube Summarizer that pulls transcripts and generates AI-powered summaries, key takeaways, and timestamped moments.

The wheel landed on Cursor. I used Composer 2 for the core build and the new Agent Window to scaffold the project, pull YouTube transcripts, and wire up AI summarization via the AI SDK + OpenRouter.
