SummarizeYT
SummarizeYT is a Chrome extension that adds YouTube video summaries while you browse. Click a thumbnail and it returns a ChatGPT-generated recap of the video so you can skip long intros and get to the main points faster.
Unlike standalone summary websites where you paste a link, SummarizeYT works directly on YouTube pages as you scroll. It targets viewers who research tutorials, lectures, and reviews but do not have time to watch every upload end to end.
The extension is powered by OpenAI GPT-3 and ChatGPT, lists about 1,000 Chrome Web Store users, and carries a 3.4 out of 5 rating from 527 reviews. The developer states it does not collect or sell user data.
