Magpie - YouTube Summarizer

Like probably everybody else, I spend a ton of time on YouTube watching all sorts of videos, and the idea of summarizing them came pretty naturally. I tried several summarization tools, but none of them clicked with me. So in the era of Claude and Codex, I vibecoded my own. I built Magpie on top of the OpenRouter API, which is great because it gives you access to hundreds of models (some of them even free). You can use any OpenRouter model you have access to to generate the summary. I also made the summarization prompts configurable, so you can find the best one just by experimenting. It’s free and open-source (MIT license). The only thing you need is an OpenRouter API key.
