How does the chess analysis work?

We use Stockfish 17, the strongest open-source chess engine. Analysis runs on our servers at depth 15+, with many positions pre-analyzed at depth 20+ from the Lichess database. We provide centipawn evaluations, move classifications, accuracy ratings, and opening detection.

Can I analyze multiple games at once?

Yes, you can import and analyze multiple games at once. We also offer batch analysis features to identify patterns across your recent games.

Can I analyze chess games for free without Chess.com premium?

Yes! While Chess.com limits free users to 1 game analysis per day, alternatives like chess.koz.tv and Lichess offer unlimited free analysis. chess.koz.tv requires no account and provides full Stockfish 17 analysis.

What is the best free chess analysis website?

For unlimited free analysis with no signup, chess.koz.tv is an excellent choice. It offers Stockfish 17 analysis, accuracy ratings, move classifications, and supports imports from Chess.com, Lichess, and PGN files.

Is Lichess analysis really free?

Yes, Lichess is completely free and open source. However, it requires an account for some features and doesn't show accuracy percentages by default. chess.koz.tv shows accuracy ratings similar to Chess.com.

How can I analyze more than 1 game per day on Chess.com for free?

You can export your Chess.com games as PGN and analyze them on chess.koz.tv for free. Simply enter your username and we'll import your games automatically — no limits, no subscription needed.

Free Chess Analysis Alternatives - Chess.com vs Lichess vs chess.koz.tv

The Problem with Chess.com Free Tier

Chess.com is the most popular chess website, but their free tier has significant limitations. Free users can only analyze 1 game per day — and that analysis runs in your browser, making your computer slow and draining battery.

Want to review multiple games from today's session? You'll need to pay for premium (starting at $7/month) or wait until tomorrow. For active players who play 5-10 games daily, this is frustrating.

The good news: there are completely free alternatives that offer unlimited analysis with no restrictions.
