ChessVault started as a personal project — a simple trainer to drill opening lines without cluttered interfaces or paywalls. It worked so well, we made it free for everyone.
The best chess training tools cost money. Subscriptions, premium features, locked content — the chess industry has decided that serious improvement requires a monthly fee.
We disagree. The knowledge of how to play a Scotch Game correctly, or why the Caro-Kann's bishop development matters, belongs to everyone. Not just people willing to pay.
ChessVault is our answer: a fully-featured, scientifically-sound opening trainer that is completely free, requires no account, and stores nothing about you on our servers. Your progress lives in your browser. Your improvement is yours.
"Chess openings are not about memorizing 20 moves of theory. They are about understanding three things: what pawn structure results, which pieces belong on which squares, and what the plan is for the middlegame. Learn those and the moves fall into place naturally."
— The ChessVault training philosophy
You can read about the Scotch Game all day. You won't remember it at the board. Playing through the lines hundreds of times — with the consequence of restarting on a wrong move — builds the kind of memory that holds under pressure.
Every wrong move you make in ChessVault is recorded in your Chess Report. Most trainers ignore this. We surface it. Knowing you mess up the Nimzo-Indian Classical on move 8 every time is the most valuable information you can have for targeted improvement.
Pure drilling gets repetitive. That's why ChessVault has six modes. The core repetition engine is surrounded by Chaos Mode for competitive pressure testing, Learn Mode for deep understanding, Famous Games for inspiration, and Blindfold modes for visualization training.
We store your progress in your own browser. Not our servers. Not a database. We don't know your email address. We don't know your rating. We don't know anything about you — and we prefer it that way. If you clear your browser, your data is gone. That's the trade-off for privacy, and we think it's worth it.
ChessVault will always be free. We support the site through non-intrusive display advertising. That's the deal. No subscriptions, no premium locks, no "train 3 lines free then pay." Every opening, every mode, every feature — free forever.
Open the trainer, pick an opening, and play your first move. It takes 10 seconds to start. No signup required.
