Fianchetto: Chess Analysis

Fianchetto is your personal chess trainer – with every engine running right on your phone.

Most chess apps make you study generic puzzles. Fianchetto does the opposite: it turns the games you already play into deep, engine-powered chess analysis and targeted training built from your real mistakes. No account, no sign-up – every analysis runs on your device, so your games stay private.

♟ GAME REVIEW & CHESS ANALYSIS
- Full engine analysis with every move classified: brilliant, great, best, excellent, good, book, inaccuracy, mistake, blunder, missed win
- Accuracy per color, ACPL, evaluation graph, key moments and brilliant-move detection
- Quick or Deep analysis – a fast blunder check or a slower, more accurate review
- Analyze one game or batch-analyze your whole library
- Share a reviewed game as an image

🧠 SEE WHAT HUMANS WOULD PLAY
- Maia-2, a neural network trained on millions of human games, shows the move players at your rating actually choose – next to the engine's best move
- Spot the natural-looking moves that are really traps
- Opening theory marked on every line, so you know when you've left the book

📖 ANALYSIS THAT TELLS A STORY
- Every game gets a plain-language narrative, divided into chapters – not just numbers
- Understand why a move was a mistake, in a popular or technical tone, in English or Polish
- The engine's plan drawn on the board as numbered arrows

🎯 TRAIN ON YOUR OWN MISTAKES
- Fianchetto auto-builds tactics puzzles from the blunders in your reviewed games
- Daily puzzles with spaced repetition (SM-2) and streaks to keep you sharp
- Hard mode: solve the full winning line, not just the first move

🤖 THREE OPPONENTS, THREE PERSONALITIES
- Maia-2 plays like a real human at the rating you pick – natural, solid, aggressive or wild
- Caissa (modern NNUE) for the objectively best move
- Arasan, a classic engine ready with no download
- Five levels, time controls, optional eval bar and hints
