Why we exist

Most revision tools hand out answers. We build ones that teach.

Students spend hours rereading notes and copying worked solutions, and very little of it sticks. The research has been clear for years: people learn by doing, by getting feedback, and by coming back to things at the right time.

Prismwell exists to put that into products students actually want to open. Yumio is where we start.
