Answers.Body: <p>Yes, it does. It uses stockfish.js, the Javascript port of Stockfish, which can run on web browsers. You can see stockfish.js mentioned somewhere on the chess.com analysis board. Also, I can tell that the computer fan starts working harder when I run an analysis, and looking at the "top" command shows that the web browser is using 100% CPU.</p>
