Built by chess players, for chess players.
CheckItApp is an independent project made to give every player access to serious analysis without paywalls.
Our Mission
Great chess analysis used to require expensive software or premium subscriptions. We think a strong engine and a smart coach should be one click away — for everyone, on any device.
How It Works
Stockfish 16 runs inside your browser using WebAssembly. Your PGN never leaves your device unless you explicitly share it. AI commentary is generated on demand for the specific position you're studying.
The Team
A small independent team of developers and chess enthusiasts based across Europe. Follow us on TikTok and Instagram @checkitapps for tips, position puzzles, and behind-the-scenes updates.
Roadmap
- Opening explorer with your personal repertoire
- Tactics trainer built from your own mistakes
- Cloud sync for saved analyses (optional, opt-in)
