The Future Together

Getting stronger together

AI isn't perfect — it can hallucinate now and then, especially when the lighting is poor or your pieces look a little different from what it has seen before. When that happens, you can correct the AI right inside the app and send the true position back to our server.

Correction screen: white knight on b1 detected as a black knight
1 · In the starting position, the AI read the white knight on b1 as a black knight.
Tapping the white knight icon and dropping it onto b1 to fix the detection
2 · We tap the correct white-knight icon and drop it on the square, replacing the mistake.
Pressing Send to share the corrected position with the server
3 · Press Send to share the corrected position with us.
Please be very careful with corrections. Every position you send is examined by hand. A wrong correction doesn't just get ignored — it can make the AI worse. So only send positions you're sure are right.

Once verified, your corrections become training data for the next model — so every careful correction helps VisionChess get stronger and more accurate for everyone.
