Ailurn turns a topic, PDF, GitHub repo, or URL into a structured course you actually study — not a video catalog, and not another ChatGPT thread. You create the course, then take it in the same workspace. Built for people who already know the goal. Plan in chat. Get modules and ordered lessons. Read, Ask, quiz, listen, and run code in the page when the subject needs it — finance, design, interviews, math, or code. Start free. You own the material.
