What Tertiary Scanner does
Tertiary Scanner captures paper documents with automatic edge detection, perspective correction and multi-page scanning. Apply one-tap filters, rotate or refine each page, then recognise text and search your saved library by document name or content.
Export polished PDFs or JPGs directly from the app. Native SwiftUI and Jetpack Compose builds keep scanning, enhancement, OCR and document storage on the device, with no account, analytics or backend required.
