Chess Title Simulator

Simulate a chess title or rating on Chess.com. Locally modifies the UI for fun and aesthetic purposes.

Add a chess title and a rating beside your username on Chess.com. Chess Title Simulator is a small extension for players who want that look while streaming, taking screenshots, or playing for fun. Choose a standard title, or type your own badge of up to 8 letters and numbers. You can also type a rating of up to 4 digits. That rating stays after a refresh until you turn it off. The change happens only in your browser. It follows your username in the sidebar, in games, and on your profile. Other players are left unchanged. Nothing is sent to a server, and your settings stay on your device. Switch the title, edit the badge, or turn the rating on or off from the popup. The page does not need a reload. The title and rating keep up as Chess.com updates the page during a live game. This extension is for entertainment only. It does not change your real rating, your official title, or anything stored by Chess.com.
