Chess Masti

ChessMasti is a free online tool that acts as a smart chess coach. It helps players improve their game by explaining moves in simple language while using powerful computer engines to check for errors. The platform was created by a high school student named Aayan Hetamsaria. His goal is to make top-level chess training available to everyone without any cost or hidden fees. The software runs entirely in your web browser, meaning you do not need to install anything on your computer. All your data stays on your device and never leaves your computer. This ensures your privacy is completely protected.

Benefits

ChessMasti offers several unique advantages over other chess training apps. First, it uses a strict engine-first system. Instead of guessing with artificial intelligence, it uses Stockfish 17 to analyze positions and then translates the results into plain English. This prevents the coach from making up facts or giving wrong advice. Second, the tool provides personalized puzzle training. It looks at the mistakes you made in your last game and finds specific puzzles to help you fix those exact errors. Third, it supports interactive analysis. You can click on moves in the chat to instantly jump to that spot on the board and explore different lines. Fourth, it respects opening theory. Unlike some engines that criticize every move, ChessMasti knows when a move is a standard book move and explains the theory behind it. Finally, the entire process is free and requires no subscriptions or credit cards.

Use Cases

ChessMasti is designed for players of all skill levels who want to improve their chess game. It works best when you have just finished a game on a site like Lichess or Chess.com. You can install the Chrome extension and simply drop it onto the chess site. After the game ends, the tool automatically analyzes your game and gives you feedback. It is also useful for practicing tactics. The system can pull puzzles from a large database that match the specific type of error you made during your game. Players can use the scouting feature to study opponents by looking at their opening choices and psychological profiles. The Twin Bot feature allows users to play against an opponent that mimics human blunders, which is great for learning from real mistakes. Advanced players can use the what-if analysis to see how the game would have changed if they had played a different move.

Pricing

ChessMasti is completely free to use. There are no monthly fees, no subscriptions, and no paywalls. Users can access all features without creating an account or entering payment information. The platform is supported by donations and is currently prioritizing users in India and Southeast Asia.

Vibes

Users have praised ChessMasti for making complex engine analysis easy to understand. One player named Alex said that the clickable moves in the chat are a game-changer because they allow him to jump directly to positions he is curious about. Another user, Priya, noted that being able to play on Lichess and then analyze with the AI coach in the same app is a huge improvement. She appreciated that the coach makes engine output readable for intermediate players. Marcus, who plays at a higher level, mentioned that the tool finally understands opening theory and does not unfairly criticize standard moves. Raghav loved that the coach explains why a move is bad instead of just saying it is bad. He found the what-if exploration very helpful for seeing lines he would never have considered.

Additional Information

ChessMasti was founded by Aayan Hetamsaria, a high school student, with the belief that elite chess education should be free. The platform is currently focusing on growing its user base in India and Southeast Asia. The team is actively hiring for an internship program in areas like engineering, content creation, growth, and research. The technology behind the tool is impressive because it runs Stockfish 17 directly in your browser using WebAssembly. This means there are no server limits or rate caps on the analysis. The system also includes a validator that checks every piece of advice against the actual game state to ensure accuracy. The puzzle database contains over 100,000 quality-filtered puzzles organized into 46 tactical themes and four difficulty levels.
