Chessou

What Chessou does.

Chessou is a chess training platform. It connects to your Lichess or Chess.com account, imports the games you actually played, analyzes them move by move, and turns your recurring mistakes into puzzles and drills you can train against.

How it works

  1. You connect your Lichess or Chess.com username, or upload a PGN file. Chessou imports your games automatically.
  2. A chess engine reviews every game and marks the critical moments: the tactics you missed, the blunders you played, and the strategic ideas you overlooked.
  3. Those exact positions become your training material. You replay them as puzzles and drills until the pattern sticks, with spaced repetition bringing each one back right before you would forget it.

What you get

  • Game reviews with comments on every critical moment, tactically and strategically.
  • Targeted training built from your own mistakes rather than from random puzzle databases.
  • Personalized training plans that adapt as your games change and as you improve.
  • Reports on your progress, plus fresh insights from every new game you play.
  • Custom drills that turn a recurring blind spot into a focused exercise whenever you want one.

Signing in with Google

Chessou offers Google as one way to sign in. When you choose it, we ask Google only for your basic profile information and your email address. We use them for a single purpose: to create your Chessou account, to recognize you when you come back, and to send you service messages such as password or billing notices.

We do not request access to Gmail, Google Drive, your contacts, your calendar, or any other Google service. We do not sell your data, and we do not use it for advertising. You can also create an account with an email address instead, without involving Google at all. Full details are in our privacy policy.
