Tactical Trade & Line Visualization

Visually analyze the consequences of any move before you play it. Chess Helper highlights winning and losing trades in clear colors, so you can instantly assess material exchanges. Furthermore, you can draw arrows on the board to visualize entire attack lines and sequences, updating the board state in real-time to plan complex tactics and combinations several moves ahead with confidence.

Engine-Powered Move Suggestion & Evaluation

Access a powerful chess engine directly within your game interface. When you're unsure, the extension suggests the top best moves, displayed as arrows on the board, along with their precise numerical evaluation score. This provides an immediate, objective assessment of the position and guides you toward the strongest continuations, turning every moment of doubt into a learning opportunity.

Full Platform & Game Mode Compatibility

Chess Helper delivers its complete, powerful feature set seamlessly across both Chess.com and Lichess.org. It works flawlessly in live games, against bots, during puzzle training, and in game analysis. This consistent experience means you have a reliable assistant wherever you play, ensuring your training tools are always available without platform limitations or interruptions.

Accelerating Beginner Development

For new players, Chess Helper is an indispensable training wheel. It instantly visualizes threats like attacks on the queen or checkmate patterns that beginners often overlook. By showing hanging pieces and safe squares, it teaches fundamental board awareness and helps build good habits from the start, dramatically reducing frustrating blunders and making the learning curve much more manageable.

Intermediate Tactics Training

Intermediate players can use the extension to deeply analyze their own games and puzzles. The ability to visualize attack lines and see engine evaluations in real-time allows for exploring "what-if" scenarios thoroughly. This deep, interactive analysis is crucial for understanding why certain moves are strong or weak, cementing tactical patterns, and improving calculation skills faster than passive study.

In-Game Decision Support During Live Games

During a tense live game, time is critical. Chess Helper provides instant tactical oversight, highlighting critical trades and threats at a glance. This allows you to make more confident, accurate decisions under time pressure, avoid oversights, and capitalize on your opponent's mistakes instantly, effectively giving you the strategic depth of a much higher-rated player.

Analyzing Puzzles & Bot Games

When practicing with puzzles or bots, the extension transforms these sessions into hyper-efficient training. You can test different puzzle solutions visually before committing, and against bots, you can use the engine suggestions to understand the optimal response to difficult positions. This turns every practice session into an active learning dialogue with immediate feedback.

On which websites does Chess Helper work?

Chess Helper is designed to work seamlessly on the two largest online chess platforms: Chess.com and Lichess.org. It is compatible with all types of games and features on these sites, including live games, daily games, bot games, puzzles, and analysis boards, providing a consistent experience across your entire online chess activity.

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

No, Chess Helper is designed as a learning and analysis aid. It does not automate moves or play the game for you. The extension provides information and suggestions, but the player must still choose and execute every move themselves. It is analogous to having a coach watching your game and giving advice, which is permitted for training purposes.

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 features—square attack analysis, trade evaluation, move previews, and engine suggestions—across both supported platforms to see how it transforms your game before making any commitment.

Can I customize the features I see?

Absolutely. Chess Helper is fully customizable through its settings panel. You can choose to turn specific features on or off based on your needs. For example, you can disable engine suggestions if you only want visual threat analysis, or configure when evaluation scores are displayed. This ensures the tool adapts to your skill level and training focus.
