Engines calculate. Coaches raise rating.
An engine finds the truth of a position. A coach turns that truth into a habit you can reuse next game.
What an engine does
Deep search, evaluations, and best moves. Outstanding at calculating a single position.
What an engine doesn't do
It won't remember you hang bishops after captures, or ask a clear question at your level.
Our split
The engine finds the truth. Your coach explains the habit, builds today's lesson, and tracks whether the mistake actually disappears.
FAQ
Do you still use an engine under the hood?
Yes — for accurate evaluations and move quality. You see the coaching, not the plumbing.
Can I see the evaluation?
Every review includes evaluations, move labels, and a coach narrative on top — in plain language. Switch on Engine mode when you want classic terms.
