Common questions
A few practical details for players comparing the experience with Chess.com.
Is ChessIQ a replacement for Chess.com?
No—ChessIQ is an analysis tool, not a place to play. It's designed to work alongside Chess.com: you play your games there, then bring them to ChessIQ for deeper analysis. Think of it as your private analysis lab.
Can I analyze my Chess.com games in ChessIQ?
Yes. Just enter your Chess.com username on the Review Games page. ChessIQ fetches your recent games via the Chess.com public API and analyzes them locally with Stockfish 18.
How deep does ChessIQ analyze compared to Chess.com?
ChessIQ offers depth presets from 13 (fast) to 50 (maximum precision). Chess.com's free tier analysis runs at a limited depth. ChessIQ's Balanced preset (depth 18) matches or exceeds what Chess.com offers free users.
Why does ChessIQ have no paywall?
Because Stockfish runs on your device via WebAssembly, there are no server computing costs for ChessIQ to cover. That's what makes unlimited free analysis possible.
