Aimchess alternative: Aimchess vs Peekchess

Daniel Kozusek13 Oct 2026 · 3 min

A good Aimchess alternative should do more than find your weak spots: it should train the calculation and visualization that fix them. Aimchess reads your games and tells you where you lose rating, then gives you drills for it. That's useful when your rating is stuck and you can't tell why. I'm a chess coach and I built Peekchess, so read this knowing that. I've tried to be fair.

1. Does the board move for you?

In most Aimchess drills you play on against the engine and the board moves with you. In Peekchess the board freezes and the moves land as arrows: you calculate the whole line without moving a piece, the way a game asks you to. The method, step by step
