Pi Scanner is a fast, private document scanner for paper you need to keep, share, or search.
Point the camera at a page. Pi Scanner finds the edges, waits until the shot is steady, and captures automatically. Skewed or angled photos are flattened into a clean, top-down scan. Scan many pages in a row into one PDF without breaking your flow.
