About

What ChessIQ is for

Review your games, keep suitable follow-up positions, and spot recurring patterns. No account required.

One review loop

ChessIQ is a local-first chess review utility built around one loop: review a game, understand the costly moments, and revisit suitable follow-up positions from your own games.

Core analysis runs with browser Stockfish 18, and core review history, saved-position state, and statistics live in local browser storage.

Public imports and analytics have narrower boundaries: username lookups call public chess APIs, while ChessIQ analytics events avoid usernames, PGNs, FENs, and move text.

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 core review history and statistics to stay in your browser.
  • You want a simple alternative when daily review limits get in the way.

Not built for

  • Live play, matchmaking, or social features.
  • Cloud sync across devices.
  • A generic tactics course or lesson library.
  • Measuring chess talent, potential, or identity.
