Fianchetto is your personal chess coach in your pocket. It combines playing against an engine, professional analysis of your own games, and personalized training built from your real mistakes - all fully offline, with no subscription and nothing ever sent to the cloud. TWO ENGINES, TWO PERSONALITIES • Caissa (modern NNUE) - shows the objectively best move. • Arasan - a classic engine with a more "human" playing style. Both are compiled natively and run 100% on your device. PLAY • Spar with the bot across five difficulty levels, from beginner to expert. • Choose your color, follow a live evaluation bar, and get engine hints. • Save any game to your Library and analyze it with a single tap. ANALYZE YOUR GAMES • Import games from Lichess and Chess.com (by username, from a link, or from a PGN file). • Every move classified: brilliant, best, inaccuracy, mistake, blunder, missed win. • Accuracy, ACPL, evaluation graph, and key moments of the game. • Quick and deep modes - catch the obvious errors first, then dig into the critical positions. ANALYSIS THAT TELLS A STORY • Every game gets a written recap split into chapters - not just numbers. • Arrows and highlights on the board, with detection of tactical motifs and opening plans. • Two narration tones: casual and technical. Available in English and Polish. TRAIN ON YOUR OWN MISTAKES • Daily puzzles generated automatically from your blunders - not from a generic database. • Smart spaced-repetition system (SM-2) and a daily streak to keep you motivated. • Train the openings you actually play: win rate, accuracy, and recurring mistakes. • Tactical stats, eval-loss heatmaps, and a ranking of your recurring weaknesses. • "Your game" dashboard: Game Score, a skill profile, and a weekly focus to improve. FREE POSITION ANALYSIS • Interactive board with a variation tree and MultiPV analysis. • Position editor, "threat goggles", arrows, and FEN/PGN paste. • Auto-saved sessions - jump back to the position you were analyzing yesterday. SCOUT YOUR OPPONENTS • Import a rival's games and prepare for the matchup. • Opening explorer, repertoire by color, and the opponent's recurring tactical weaknesses. PRIVACY FIRST • All analysis runs on your device - your positions never go to the cloud. • Your data (games, analyses, puzzles) is stored locally. You can wipe it anytime. Fianchetto is built for the club and amateur player who wants to improve systematically - with no subscription and no compromise on privacy. Install it, import your games, and start playing smarter.
