How this works
The four corners define a perspective transform that flattens the board into a clean 8×8 grid. The scan samples frames, finds moments when the board is still (no hands), and compares square colours between consecutive still moments. It never tries to identify piece types — it only asks which squares changed, then picks the legal move that best explains the change. Anything it gets wrong is fixable on the Review screen.
Detected moves — check & correct
Each row is one move the scan found. Low-confidence rows are highlighted — click the move dropdown to pick the right one. Everything after an edit is re-checked automatically.
| # | Board | Move | Confidence | Time | Squares that changed | Fix |

Drag or click pieces to play any legal move from the current position — it becomes a branch you can explore, and the real game stays intact. ← → navigate, F flips, Backspace takes back.
