Explanations

Youtube videos helped millions - but teachers don't get rewarded. Private tutoring is impactful - but it's expensive as hell. explanations.app is a middle-ground between Youtube & Tutoring. Lots of students pay $10/month to a Youtube Teacher, who creates videos based on the questions students ask. About 5 TAs, researchers & students from MIT have signed up to become teachers, but anyone can teach, anyone can learn, it's an open platform, and I think the real world has much better incentives than universities.
