Chess Helper

Chess Helper is your personal, game-changing assistant that transforms how you learn, analyze, and play chess online. Designed to unlock the strategic potential within every player, it seamlessly integrates directly into the world's two largest chess platforms: Chess.com and Lichess.org. This powerful browser extension acts as a real-time coach, providing immediate visual and analytical insights that were once the exclusive domain of advanced software or grandmaster intuition. Whether you're a beginner struggling to see the board clearly or an intermediate player aiming to eliminate costly blunders, Chess Helper bridges the gap between your current skill and your aspirational mastery. Its core value proposition lies in demystifying complex positions, revealing hidden tactical opportunities, and providing engine-powered guidance—all without ever leaving your game. By instantly highlighting attackers, visualizing entire sequences, and suggesting the strongest moves, it empowers you to make confident, informed decisions and accelerates your learning curve like never before.

Real-Time Board Analysis

This foundational feature revolutionizes your perception of the board. At a single glance, you can see all attackers and defenders for any square, instantly identify hanging pieces, and spot potential checks. It eliminates the mental strain of manually calculating trades and piece safety, providing a clear, color-coded visual overlay. This immediate awareness helps you secure your position and capitalize on your opponent's weaknesses, effectively training your eye to recognize critical patterns and dramatically reducing simple oversights.

Tactical Visualization & Move Preview

Unlock the power to see several moves ahead without making a single commit. This feature allows you to draw arrows directly on the board to plan out attack lines and complex tactical sequences. As you visualize your moves, the board state updates in a preview pane, showing you the resulting position. This is transformative for exploring sacrifices, planning combinations, and understanding the concrete consequences of your ideas before you play them, turning abstract calculation into a tangible, visual process.

Engine-Calculated Best Move Suggestions

Harness the analytical power of a built-in chess engine that works in real-time during your games and analyses. When you're uncertain, the engine provides top move suggestions displayed as arrows on the board, complete with numerical evaluation scores. This offers a direct line to strategic understanding, explaining why certain moves are strong and helping you learn the principles behind master-level play, effectively giving you a grandmaster's second opinion at your fingertips.

Fully Customizable Experience

Chess Helper is designed to adapt to your unique learning journey and preferences. The extension is fully customizable, allowing you to tailor its assistance to your exact needs. You can choose to disable engine suggestions if you want to train purely on visualization, configure when evaluation scores appear, or adjust which visual highlights are active. This ensures the tool supports your development without becoming a crutch, providing a personalized experience that grows with you.

Accelerating Beginner & Intermediate Improvement

For players moving beyond the basics, Chess Helper acts as a constant training partner. By instantly revealing threats and opportunities that are often missed, it provides immediate feedback that accelerates pattern recognition. Beginners can avoid fundamental blunders like leaving pieces undefended, while intermediate players can deconstruct why a move is good or bad, building a deeper, more intuitive understanding of positional and tactical chess principles much faster than through solo study alone.

In-Depth Game Analysis & Post-Mortem

After a game, whether a win or a loss, Chess Helper transforms the review process. Instead of guessing, you can use the visualization and engine tools to explore alternative lines, understand critical turning points, and pinpoint exact mistakes. This allows for a thorough and educational post-mortem analysis, helping you learn concrete lessons from every game and identify recurring weaknesses in your play, turning every match into a valuable learning session.

Mastering Puzzles and Tactical Training

When working on chess puzzles on Chess.com or Lichess, Chess Helper supercharges your tactical training. The visualization tool lets you test different candidate moves and sequences without giving up, deepening your calculation skills. The attacker highlights can also provide subtle hints, guiding your thought process toward the correct solution and helping you internalize complex tactical motifs like pins, forks, and skewers more effectively.

Enhancing Play Against Bots and in Casual Games

Use Chess Helper as a supportive guide when practicing against computer bots or in unrated casual games. It provides a safety net that allows you to experiment with new openings and strategies without the fear of instant punishment for a oversight. You can test the viability of aggressive plans with the move preview and verify your positional ideas with the engine, creating a low-pressure, high-learning environment to expand your chess repertoire.

On which platforms does Chess Helper work?

Chess Helper is designed to work seamlessly on the two most popular online chess platforms: Chess.com and Lichess.org. It provides its full suite of features across both sites, including during live games, correspondence games, bot games, puzzles, and analysis boards. This ensures a consistent and powerful assisting experience regardless of which platform you prefer to use for your chess activities.

Does using Chess Helper violate terms of service on Chess.com or Lichess?

No, Chess Helper is designed as a legitimate learning and analysis aid. It does not automate moves or play the game for you. The extension provides visual insights and suggestions, but the final decision and move execution remain entirely with the player. It is intended for use in casual games, analysis, and puzzles. However, you should always avoid using any assisting tools during rated games where they are prohibited, as this would be considered cheating.

Is there a free trial available?

Yes, Chess Helper offers a full-featured 30-day free trial when you add the extension to Chrome. This allows you to experience all its transformative features—real-time analysis, visualization, and engine suggestions—across Chess.com and Lichess.org with no commitment. After the trial period, a subscription is required to continue using the service.

Can I customize the features I see?

Absolutely. A core philosophy of Chess Helper is personalization. The extension includes a comprehensive settings panel where you can toggle individual features on or off. You can disable the engine suggestions, configure how and when board highlights appear, and customize the display of evaluation scores. This allows you to tailor the tool to your specific training goals and desired level of assistance.
