I've come across this tool on Twitter. It summarises a youtube video using GPT-3 and it works great. 🤯 This is going to be an absolute time saver. https://www.summarize.tech/. Tool creator: Pete Hunt

Interesting. How does it work? Does it identify/highlight any unique bits of info in the video, understand any nuances, or simply parrots the "lowest common denominator" populist text it is trained on? (i.e. is it another "uncle" that spreads fake-news?)

Not exactly sure about the implementation. Here is the product hunt page. Looks like he is using youtube video transcript for generating the summary. Check this thread
