ChessKit is a free web application for analyzing chess games with an emphasis on clear, visual presentation of key moments. Upload a PGN or link a game from Lichess or Chess.com, and ChessKit runs engine analysis to identify brilliancies, blunders, inaccuracies, and critical turning points — then presents them in a visually appealing, shareable format.

The tool is particularly oriented toward highlighting the best moves in a game rather than just cataloging errors, making it useful for sharing impressive games with a wider audience who may not be familiar with engine notation. The annotated output can be shared as a link.

ChessKit is entirely free and requires no account. It sits in a similar space to Chess.com's game review but with a distinct focus on the storytelling of a game's key moments, and without requiring a premium subscription.
