Everything a chess improver needs, in one app

A quick tour of what's inside — from playing and analyzing to training and prep.

Every feature is free. A few actions (like full AI analysis) use credits — the Free plan includes 5 credits/month, and Pro includes 200.
Play Bots

Opponents that feel human — at your level

The Nova engine is a neural network trained on 500M human games, with rating and stylistic conditioning. It predicts human moves as accurately as Maia 3, and above 1900 it plays more truthfully to its stated rating than Maia does.

Face Legends like Morphy and Tal, plus a roster of bots with distinct playing styles. Players have already played 4,000+ games against the Nova engine.

Analyze

A fast study board with AI game review

Import your games from Lichess or Chess.com with one click and study on an interactive board. Stockfish runs on remote servers so it's quick — depth-30 on Pro, depth-20 on Free.

Run a quick review, or a full AI analysis built on a positional-features architecture — in the spirit of DecodeChess or pre-NNUE Stockfish — for reliable, readable move and position explanations.

Analyze
Player Insights

Understand your game at a glance

Scan up to 1,000 of your recent Chess.com or Lichess games to reveal your playing style and your biggest opportunities to improve.

Generate a full coaching report that works through your games and classifies the different types of mistakes you tend to make — so you know exactly what to work on.

Player Insights
Opening Explorer

Openings — and your own repertoire
