A clean, intuitive, and local-first interface for deep Stockfish analysis, local SQLite database management, and AI game reports. 100% free and open-source.
Load games from local PGN files, paste raw PGN text directly, or fetch your games history asynchronously from Chess.com and Lichess using their public APIs.
Run complete calculations locally using the Stockfish chess engine. Navigate through moves with the interactive evaluation graph and follow the real-time best lines on the live engine panel.
Tailor the application to your exact study workflow. Configure local engine threads, hash memory, search depth limits, customize piece/board appearance themes, and import Polyglot opening books (.bin) offline.
All analyzed games are stored locally in an SQLite database. Search, paginate, sort, and query your games history without uploading any information to cloud servers.
Sweating the details so you can focus on studying, not clicking.
One dialog for all sources: PGN files, pasted PGN text, Chess.com usernames/URLs, and Lichess usernames/links. Fetches asynchronously so the UI stays responsive.
Checks moves against the built-in SQLite opening database, Polyglot .bin books, or the Lichess Opening Explorer. Book moves are highlighted separately.
Choose your live accent color, piece set (Standard/Cburnett, Merida, Alpha, Cardinal, Chess7), and board theme (Green, Brown, Blue, Purple, Grey).
Navigate moves with arrow keys (←/→), jump to start/end with Home/End, open game with Ctrl+O, paste PGN with Ctrl+V, and run analysis with Ctrl+A.
CC0-licensed synthesized sound effects for moves, captures, checks, castles, and game results. Can be toggled on or off in Settings.
Configure CPU cores, memory limits, and analysis depth. Conservative safe defaults protect laptops from overheating during calculations.
Export your entire local game history to a CSV file for backups, and import it back on any device. Keeps your data portable without lock-in.
Board highlights last move, displays captured pieces with material balance counts, supports board flipping, and displays best-move arrows.
Checks GitHub releases once per day on startup and alerts you if a newer update is available, providing a direct download link.
Every detail, optimization, and integration built into Chess Analyzer Pro.
