Educket explains the ideas everyone keeps mentioning (AI agents, RAG, credit scores, unit economics) in about 5 minutes. Each lesson gives you one picture you won't forget and real cases to try the idea on, then asks you to explain it back in your own words, so you know you actually get it. 300+ lessons across AI, money, business and security, each designed and reviewed by people. Pro members can request any missing topic. Free to try with no sign-up. On iPhone today, Android next.
