In short

Video Mood is a BYOK (Bring your own key) AI YouTube video summarization tool that uses the Open AI API.

When I was in Thailand, I participated in a little challenge where 2 friends and I had to create an app MVP in 4 hours. It was really intense, but I managed to do it in 3h55! I then spent around 25 more hours over the next few weeks improving the product.

I don't think that I'll continue working on this project as Google Bard can now analyze YouTube videos, and I don't think that relying on this knowledge asymmetry is a solid way of building a sustainable business.
