What ChessIQ is for
Review completed games, keep useful positions, and spot recurring patterns. Free, independent, and no ChessIQ account required.
One review loop
ChessIQ is a free, independent chess review tool built around one loop: review a completed game, understand the costly moments, and revisit useful positions from your own games.
Stockfish 18 analysis runs in a browser worker after the engine assets load. Review history, saved-position state, and Insights data are stored in this browser by default.
Username and game-link imports pass through ChessIQ server routes before reaching public Chess.com or Lichess services. Hosting, rate limiting, and privacy-friendly page analytics have separate, limited boundaries described in the Privacy Policy.
Good fit
- You want to review your own games after they are played.
- You want saved follow-up positions from real mistakes and missed chances.
- You prefer review history and saved positions to stay in your browser by default.

Not built for

Focused guides
Independent and free
ChessIQ is an independent project by Jeromy Mobley. It is not affiliated with Chess.com, Lichess, or the Stockfish project.
The web app is available now and is permanently free to use. A native ChessIQ app is not currently available for download; current availability is listed on the Apps page.
The app is built with Next.js, React, TypeScript, browser Stockfish 18, chess.js, and public Chess.com/Lichess imports. Stockfish source and license details are available in the bundled engine notice.
