Chess Helper

About Chess Helper

Chess Helper is a Chrome extension for players who want more insight while playing on Chess.com and Lichess. It is aimed at learners and club players who want to understand tactics better during their games and puzzles.

The extension shows attackers for each square, highlights possible checks, and flags hanging and pinned pieces so you can spot threats at a glance. You can draw arrows on the board and see how the position changes after your planned moves, which helps when exploring tactics or complex positions.

A built-in chess engine suggests the top moves in real time, shown as arrows with evaluation scores. Every feature can be turned on or off, and evaluations can be delayed until after you move. The site says the full feature set works the same on both platforms, including with bots and puzzles. A 7-day free trial is offered before purchase.
