BUILT AROUND YOUR ORIGINAL

The Document filter is applied to new imports to improve readability. Your original image remains available, so you can revisit filter, brightness, contrast, rotation, and handwriting-removal edits. Handwriting removal runs only when you request it. Results depend on the source, and Erase and Restore tools let you adjust the removal area.

Documents are stored on your device. After importing or scanning, cleanup, OCR, editing, search, and export work offline. No account, sync feature, or in-app purchase is included.

PRIVACY

Image processing, handwriting detection, and OCR run locally on your device. Imported images, PDFs, and recognized text are not uploaded to an external server for processing. The app does not include tracking or analytics.
