Chessr Review Unlocker

Chessr.io - Review Unlocker gives you full game review on chess.com without a Diamond subscription.

One click from any finished chess.com game and the extension unlocks a detailed review powered by chessr.io:

• Accuracy for both players across the full game
• Move-by-move classification: brilliant, great, good, inaccuracy, mistake, blunder, missed win…
• Effective Elo estimated for the game, for White and Black
• Visual summary right inside the popup, plus a link to the full review on chessr.io (evaluation graph, variations, move-by-move comments)

How it works: open a finished game on chess.com (or its analysis page), click the chessr.io icon, then hit "Unlock review". The analysis runs and appears in a few seconds. Already-analyzed games are saved — one click reopens them instantly.

Who it's for: chess.com players who want to understand their mistakes and improve without paying for Diamond.

Free account with a daily review quota, or Premium for unlimited analyses. The extension only runs on chess.com pages and never reads data outside the game you're viewing.
