Chess tools
Small, free tools that take your username and tell you something about your chess. Nothing to install, no account, and nothing about your games is stored.
Tilt Clock #
Answers one question: when should you stop playing?
It reads your game history and looks for the patterns people assume are there. Scores falling deep into a session, after a run of losses, late at night. Then it tells you which of them your own data actually supports. Often the answer is none of them, and it says so.
How this works #
Games come from the public Chess.com API through a small caching service, and every calculation happens in your browser. Nothing is sent anywhere else, no usernames are logged, and there is nothing to sign in to.
