# Sing Chess

> Sing Chess provides chess game review, puzzles, a chess Coach, and online Play through a connected Lichess account.

Browser reviews and puzzles can be used without an account. Sign-in is required for saved account progress and Lichess Play. Analysis and coaching are paused during active online games. Ratings and move classifications are estimates; imported provider ratings and reviewed-game statistics have different scopes.
