How it works

Your games become your training plan

No generic curriculum. What you train next comes from the moves you actually played, so the work goes where your points are lost.

01

Import your games

Enter your Chess.com or Lichess username, no password. Your recent games come in first, your history follows, and new games are picked up when you come back.

02

Every game reviewed

Stockfish scores each move: accuracy, blunders, mistakes and the better move you missed. A weekly report shows how your games went.

03

Your mistakes, back as positions

Each mistake becomes a position from your own game. Spaced repetition brings it back until the right move comes without thinking.

04

Five minutes a day

The Daily 5: five due positions, about five minutes, with a reminder at the hour you pick. Your progress page shows what is sticking.

Game review

See where the game turned

Stockfish 18 checks every move in your browser: accuracy for both players, each mistake marked, and the evaluation graph that shows the moment it slipped.

Opening explorer

Find your best openings and the leaks to fix

Every game you played with a colour, merged into one opening tree. Follow a line move by move: how often you reach it, how you score in it, and what the engine thinks of your choice.

Your score, opening by opening
Games, wins, draws and losses on every branch, for the lines you choose and the replies you meet.
Where you lose points
Your main line, your best line and your biggest leak are picked out for you, so you know where to look first.
The move you keep playing
Each of your moves sits next to the engine's evaluation, so a habit that costs you games stands out.
