Common questions
Is Chessomy a replacement for Chess.com?
No—Chessomy 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 Chessomy for deeper analysis. Think of it as your private analysis lab.
Can I analyze my Chess.com games in Chessomy?
Yes. Just enter your Chess.com username on the Review Games page. Chessomy fetches your recent games via the Chess.com public API and analyzes them locally with Stockfish 17.1.
How deep does Chessomy analyze compared to Chess.com?
Chessomy offers depth presets from 13 (fast) to 50 (maximum precision). Chess.com's free tier analysis runs at a limited depth. Chessomy's Balanced preset (depth 18) matches or exceeds what Chess.com offers free users.
Why does Chessomy have no paywall?
Because Stockfish runs on your device via WebAssembly, there are no server computing costs for Chessomy to cover. That's what makes unlimited free analysis possible.
