Frequently Asked Questions

Is this as good as a real scanner?

For typical documents like receipts, contracts, and notes, the results are comparable to a flatbed scanner. For archival-quality scans of photographs or artwork, a dedicated scanner is still recommended.

Does it work with handwritten notes?

Yes. The contrast enhancement makes handwritten text more legible. For extracting text digitally, use our OCR tool after scanning.

What about whiteboards?

Whiteboard photos work great. Perspective correction straightens angled shots, and contrast enhancement makes marker text stand out clearly.

Are my documents kept private?

Yes. Documents are processed entirely on your device and are never sent to any server.
