At a glance
Two useful reviews with different jobs
Chess.com documents its current Game Review workflow and notes that settings can change classifications. Its feature access can change, so check its current product page for account and membership details.
The important difference
The labels do not use the same scoring model
Chessdesk converts Stockfish evaluations into win percentage using the formula published by Lichess. It then applies the same fixed loss thresholds to every player: 5 win-percentage points for an inaccuracy, 10 for a mistake and 20 for a blunder. Chessdesk's brilliant and great labels also use explicit rules described in the move-classifications guide.
Chess.com's current Expected Points model combines engine evaluation with the player's rating. Chess.com publishes Expected Points loss bands for Excellent, Good, Inaccuracy, Mistake and Blunder, then applies extra rules to Great, Brilliant and Miss. Some of those special rules are more generous for newer players. Because the underlying models differ, matching labels or accuracy scores should not be expected.
Which should you use?
Choose for the workflow, not for matching labels
Use Chess.com Game Review when you want its guided Coach experience inside Chess.com. Use Chessdesk when you want a quick review without creating another account, need the same workflow for Chess.com and Lichess games, or want fixed thresholds you can inspect. For a second opinion, compare the turning points and engine lines rather than expecting identical badges.
FAQ
Questions about the alternative
Is Chessdesk affiliated with Chess.com?
No. Chessdesk is an independent chess workspace. It can fetch recent public games by Chess.com username, but it is not affiliated with or endorsed by Chess.com.
Can I review a Chess.com game without a Chessdesk account?
Yes. Enter your public Chess.com username, choose one of the five recent games shown and run the review. No Chessdesk sign-up or payment details are required.
Will Chessdesk give the same labels and accuracy as Chess.com?
Not necessarily. Chessdesk uses fixed win-percentage-loss thresholds based on Lichess's published model. Chess.com's Expected Points model also uses the player's rating, and analysis settings can differ. The same move can therefore receive a different label or score.
Does the alternative also work with Lichess games?
Yes. The same Chessdesk review accepts a public Chess.com or Lichess username, so you can use one review workflow for either source.
