Yes — you can play the engine, solve puzzles, train openings and endgames, and use the coach without paying. Create a free account to save your games and track your progress across devices.

No. You can play and train as a guest straight away. A free account just means your games, puzzle history and coaching are saved and synced rather than living only in your browser.

The coach watches the games you play and the puzzles you miss, then tells you — in plain language — what to work on next: the weakest phase of your game, the tactics you keep dropping, and a focused plan to fix them. During a game you can ask it for the reason behind a move, not just the move.

The engine ranges from a gentle beginner to a strong opponent, with playing styles from balanced to aggressive or positional. Start where you're comfortable and step it up as you improve — the goal is games you can actually learn from, not ones you're crushed in.

Yes. In Analysis you can paste a PGN or pull your recent games from your Chess.com or Lichess username, then step through them and run the engine to see accuracy, mistakes, and the moment the game turned.

Puzzles are real tactical positions filtered to your level, and the ones you miss can come back as targeted practice — so you drill the exact patterns you blunder rather than random positions.
