Type anything you want to understand. Mull writes a short lesson as you read, with diagrams, quizzes and sources, and a tutor beside the text. Then it turns the key ideas into cards and brings them back right before you’d forget them.

Hey Product Hunt! 👋
I built Mull because I kept running into the same thing: I’d learn something, feel like I understood it, and a week later it was gone. Chat apps are great at explaining, but they explain once and that’s it.
So Mull does two things. First, you name anything you want to understand and it writes you a short lesson while you read. It isn’t a wall of text. There are diagrams you can step through, quizzes and real sources, and a tutor sits beside the lesson if something doesn’t click. If a lesson is too dense, tap Simpler and it rewrites from there.
Second, and this is the part I care about most, when you finish, the key ideas become cards, and Mull brings each one back right before you’d forget it. The gaps grow each time: 4 days, then 14, then 44.
It’s free to try with 5 lessons a day, and there’s a Pro plan if you want more.
I’d really love your honest feedback. Was your first lesson actually good? And would you come back the next day to review it? I’ll be here all day answering everything 🙏
