Best Chess Analysis App
About this site
Who runs it, why it exists, and the conflict of interest you should know about.
Best Chess Analysis App is a comparison site about the apps and tools you can use to analyze your own chess games. It is published by the team behind ChessHelper (chesshelper.ai), a Chrome extension and website for chess analysis.
Our relationship with ChessHelper
ChessHelper is our own product. We make money when people subscribe to ChessHelper Pro. That is a material connection, and under the US Federal Trade Commission's rules on endorsements and reviews (including 16 CFR 465.6 on insider reviews) you should know it before you read any of our rankings. Every page on this site repeats the disclosure in its header and footer.
We rank ChessHelper first for one specific need: analyzing your own games at your own level, with a history of your games kept for you. We do not claim it wins everything. Our pages name the tools that do better in other categories, such as the free Lichess analysis board for full-strength analysis and opening research, Chess.com Game Review for players who play on Chess.com, and ChessBase for database work.
Why the site exists
Search results for analysis apps are full of lists that copy each other's feature claims. We wanted one place that states, for each tool, exactly what its own website and help center say, including prices as listed and the actual rules platforms use to call a move a blunder. We also wanted guides that teach a review routine rather than just naming products.
How we write
We compare published features and pricing. Facts about other products come from those companies' own websites, help centers or source code, checked on the date shown on each page. Where a company does not publish a detail, we say so instead of guessing. We do not publish user reviews, star ratings, invented testers or invented statistics.
Every chess move, line and evaluation on this site was checked for legality with chess.js and evaluated with the Stockfish engine. Evaluations are given with the search depth, because they change with depth and engine version. Details of our criteria are on the how we compare page.
Fair play
We write about analysis of finished games, study, and practice against bots or in analysis mode. Chess.com, Lichess, FIDE and US Chess forbid outside help during games against people, and Chess.com's policy covers unrated games too. We never recommend engine help in such games.

If a price, feature or chess line on this site is wrong, email [email protected] with the page address and what you found. We check reports against the vendor's own site and correct confirmed errors, updating the date on the page. Details are on the contact page.
