Looking for advice on an app I’m thinking about

Hey yall I am a game dev and I am thinking about some projects and a buddy of mine said that an app that helped people learn what they want to would be amazing. I would want to not only help people learn academic topics but also day to day knowledge. Maybe courses on how to be a better person(improving social skills and patience). I would also like to help with sciences, math, history and language skills to help people out that may still be in school or learning for fun.
