Version 1 focuses on clear 2D diagrams in screenshots and printed pages. Check the crop, every piece, and orientation before analysis. Unfamiliar or shaded piece designs can produce many errors and may need substantial manual correction. Reliable physical-board recognition is not promised in version 1. Try 10 free analysis credits with your own images before buying. A credit is used only when a scanned position produces its first successful engine solution. Failed or cancelled analysis does not use a credit, and analyzing the same scanned workspace again does not use another credit. Lifetime Pro is a one-time purchase that removes this limit—no subscription. Pro does not improve recognition accuracy.
