I built Focus2Flow because I was tired of watching 20+ minute videos for a single useful explanation.

What it does:

You type a study question like "What is the Lagrangian in physics?"

It analyzes YouTube

It returns direct links to the most relevant timestamps in videos, and code snippets

If nothing exists, it uses GPT to generate its own clear explanation

Bonus: it gives you AI-generated flashcards, a study playlist system, and lets you take timestamped notes

It now even lets you quiz yourself after each session

Works for any subject, not just STEM — law, medicine, finance, philosophy.

I’d love feedback from this community — and if anyone wants to help integrate more open educational data sources, I’m game.
