How it works
Three habits, built for short daily sessions.
Set your own daily practice time. Keystral picks the right questions, paces them to your child, and scores every answer.
Practise adaptively
The engine tracks what you already know and gives you more of what you don’t — no busywork, no time wasted.
Track real progress
Topic-level mastery, predicted grades and a short list of exactly what to revise next. No guesswork.
See it adapt live
Three questions. One personalised path.
Try it yourself. Each answer rewrites the next question and updates the mastery score on the right — exactly how Keystral works for every learner, every day.
