Everything You Need to Digitize Books
Smart Auto-Capture
Set your capture interval and let the app do the work. Edge detection ensures every page is framed perfectly, even at speed.

Fine-tune your crop rectangle to match any book size. Mirror symmetry ensures both pages are cropped identically — one adjustment, two perfect pages.
