Don't just hear it — check if it stuck
After each summary, a short quiz and a few takeaways. The point isn't the badge. It's being able to explain the idea later without opening the app again.
- A short quiz after every book
- Takeaways saved in your library

From early readers
What people tell us
I used to buy books and never open them. Now I finish one on the train ride home. Not every day — but enough that the pile on my nightstand finally got smaller.
The quiz at the end is what sold me. I used to forget summaries by Friday. Now I can bring up a point in a meeting without scrambling.
I turned on the step unlock mostly as a joke. Then I started walking more so I could unlock Deep Work. Weirdly motivating.
