Play Smarter Chess with AI-Powered Insights

ChessHelper.ai operates as a browser extension that reads the board position and provides analysis in a separate overlay. While the extension itself is not detectable by the chess platforms, using external assistance during rated games violates the terms of service of most chess websites. We recommend using ChessHelper.ai for learning, analysis, and casual unrated games only. Always play fair in competitive matches.

You can set the engine strength anywhere from 800 to 3200 ELO. Lower settings give you suggestions that match how real players think at that rating — perfect for training against realistic opponents. Higher settings provide grandmaster-level precision for deep analysis. This range covers everything from beginner-level play to super-grandmaster strength.

Human-Like Play mode automatically varies the suggestion strength at configurable intervals during your game. Instead of every move coming from the same engine depth, the strength fluctuates naturally — just like a real player who doesn't find the best move every time. You control how often and by how much the strength varies.

Autoplay lets the AI make moves on your behalf automatically. You can configure the delay between each move to match your preferred time control — from fast bullet-style play to slower, more deliberate classical timing. This is great for studying how different strategies unfold over a full game.

Yes! Your dashboard stores all your games with move-by-move analytics. You can review each game, see where you made strong or weak moves, and track your improvement over time with rating progression charts.

ChessHelper.ai currently supports Chess.com and Lichess, the two most popular online chess platforms. The extension automatically detects when you're on either platform and seamlessly integrates with the board interface. We're actively working on adding support for additional platforms based on user feedback and demand.

You can cancel your subscription at any time from your dashboard. Simply go to your account settings and click 'Manage Subscription' to access the Stripe customer portal. From there, you can cancel, upgrade, or downgrade your plan. If you cancel, you'll retain access to your current tier until the end of your billing period. There are no cancellation fees or hidden charges.
