AI Coach

Train with a coach that explains every move

Play against the Cyber Chameleon and get live coaching notes as you go — why a move worked, what you missed, and what to try next.

Full-strength Cyber Chameleon

AI Coach is a training game against a coach that talks while you play. After each decision you get a short note on the board: what changed, what the stronger idea was, and how to think about the next few moves.

Mid-game you can ask why something happened. The chat stays tied to the position on the board, so the answer is about this game, not a generic tip.

Credits, not another subscription wall

Sparring bots are free for signed-in members. AI Coach games use credits: free members get a monthly allotment, and Unlimited gets more. Top-ups are available when you want extra coached games in a busy month.

  • Signed-in members unlock AI Coach.
  • Free plan: monthly coach credits.
  • Unlimited: a larger monthly allotment, with optional top-ups.

When you want practice without the lecture

If you want volume without coaching notes, open Sparring instead. Same board, styled opponents at set Elo bands, and no credit cost for members.

FAQs about ai coach

Do I need an account for AI Coach?

Yes. Sign in to unlock AI Coach and use your monthly credits. Guests can still browse the rest of the site and solve puzzles without an account.

How is AI Coach different from Sparring?
