Features

Auto edge detection

AI finds the document boundary in the photo — even on cluttered desks — and crops precisely to the page edges.

Perspective correction

Tilted or angled shots are straightened automatically so the output looks like a flat scanner result.

Readability enhancement

Text and diagrams are sharpened, contrast is boosted, and shadows are reduced for a clean, legible output.

Works with any paper

Letters, receipts, whiteboards, books, ID cards, and handwritten notes are all detected and processed.

Faster than a flatbed scanner

Snap a photo with your phone and get a scannerlike result in seconds — no hardware needed.

Chain with OCR

Crop and enhance first, then run Image to Text to extract the content into editable text or a spreadsheet.
