Chess.com Game Review Exporter

WHAT IT DOES

Chess.com Game Review Exporter helps you save and share your Chess.com game analysis by exporting move-by-move reviews to multiple formats. The script extracts player names, ratings, game result, accuracy scores, move-by-move analysis, and computer evaluations from any Chess.com game review page. A floating export button appears on game review pages—click it to download the analysis as a PGN file (with analysis comments), formatted text, or Markdown table. The dashboard shows a summary of key game statistics including accuracy, best moves, inaccuracies, mistakes, and blunders. Move annotations include computer evaluations and quality labels. You can choose to include or exclude analysis comments, accuracy scores, and computer evaluations. A quick copy button lets you copy the PGN with analysis comments directly to your clipboard. The move list can be filtered by move quality (all, blunder, mistake, inaccuracy).

WHERE IT RUNS

This script runs on Chess.com, specifically on game review pages, analysis pages, and completed game views. It works on both desktop and mobile views, automatically detecting game data and analysis results.

HOW TO USE

After installing through the BotGentz extension, navigate to any Chess.com game review page. A floating export button appears on the page. Click it to download your game analysis. Use the configuration panel to customize your export: choose the export format (PGN, Text, or Markdown), toggle analysis inclusion on or off, toggle accuracy inclusion on or off, toggle comment inclusion on or off, and filter moves by minimum quality (all, blunder, mistake, inaccuracy). The panel displays a summary of the game—players, ratings, result, accuracy, and statistics. Use the "Scan Game" button to manually re-scan, "Export" to download the analysis, or "Copy PGN" to copy the PGN with analysis comments to your clipboard.

GAME REVIEW DATA EXTRACTION WITH MOVE-QUALITY CLASSIFICATION AND MULTI-FORMAT EXPORT

This script implements a game review extraction engine using DOM traversal with platform-specific selectors for Chess.com's game review elements. The engine extracts player names and ratings using pattern matching, accuracy scores from accuracy elements, and moves from move list containers. Each move is classified by quality (best, good, inaccuracy, mistake, blunder) using CSS class detection and text pattern matching. The PGN generator produces standard PGN format with analysis comments in curly braces. The text generator produces a formatted plain-text report with statistics. The Markdown generator produces a table-based report. The quality filter allows users to show only moves of a certain quality or worse.

THE PANEL

The configuration panel is fully draggable and remembers its position per-site using GM_setValue. It snaps to screen edges when dragged near them, collapses to a compact bubble when minimized, and supports Escape key for quick collapse. All settings—including button visibility, export format, analysis inclusion, accuracy inclusion, comment inclusion, and minimum quality filter—are persisted across sessions.

PLEASE NOTE

This script requires the free BotGentz extension to run. The script runs on Chess.com and reads game review data from the page. It does not capture, store, or transmit any personal information. All game data is processed locally in your browser and never transmitted to external servers. The script reads only publicly visible game review information displayed on the page. Due to Chess.com's page structure, some analysis data may not be available for all games. The export format options allow you to save your analysis for offline review, sharing, or import into other chess analysis tools. This tool is provided for informational and entertainment purposes only.
