For parents
- What it practices: spotting mistakes, explaining why, finding rules in patterns, and the habit of thinking first and then checking. It builds thinking skills with short, regular practice.
- What it is not: a test, a diagnosis, or a score that labels your child. We make no claims about IQ or school admissions.
- Private by design: no ads and no tracking. Guest play is never saved. If you sign in and pick a child profile (a nickname and grade band, never a real name), only that child's practice results are saved to your account, and you can delete them any time. The pretend "AI" answers are written by people, and no chatbot talks to your child.
- Try it together: every activity works well as a conversation. Ask "how did you decide?" more than "did you get it right?"
