Scanning Documents With Your Phone
Turn your phone into a document scanner — auto-deskew, multi-page capture, server-side OCR, GPS-stamped provenance.
Scanning Documents With Your Phone
The Papyrus mobile app turns any modern phone into a competent document scanner. Useful for: field inspections, in-the-moment capture of paper documents, processing supplier invoices that arrive in physical form.
Quick scan
- Open the Papyrus mobile app
- Tap the camera (✚) button on the home screen
- Point at the document
- App auto-detects edges — green outline confirms good framing
- Tap the shutter
- Multi-page: tap “Add page” for the next side
- Tap “Done” when finished
- Review the deskewed result
- Configure: destination folder, tags, classification
- Tap “Upload”
The document queues for upload. If you're online, it starts immediately; if offline, it waits for connectivity.
What the app does to your photo
Before upload:
- Edge detection: finds the document boundary
- Perspective correction: makes the captured rectangle truly rectangular even if you tilted the phone
- Deskew: rotates to align horizontally
- Contrast normalisation: improves OCR readability
- Multi-page combine: merges multiple captures into one PDF
What it doesn't do:
- Erase visible marks (signatures, stamps, handwriting stay)
- Remove redacted content (you'd want a real redaction tool for that)
- Translate or summarise (the Copilot does that, later)
GPS and timestamp
By default, photos capture:
- GPS coordinates (with accuracy estimate)
- Device timestamp
- Device model fingerprint
- Your signed-in identity
This metadata is stored alongside the document. For field-officer workflows (NGO programme delivery, inspection records, county-level service evidence), this provenance is genuinely useful for audit.
If you don't want GPS captured for a specific scan, toggle GPS off in the camera screen (gear icon).
Multi-page documents
For a multi-page document:
- Capture page 1 (auto-detect, shutter)
- Tap “Add page”
- Capture page 2
- Repeat for as many pages as needed
- Tap “Done”
The pages combine into one PDF. Order matches the order you captured.
Reorder, retake, delete
After capture but before upload:
- Reorder: long-press a page thumbnail and drag
- Retake: tap a page → “Retake”
- Delete: tap a page → trash icon
Quality tips
- Hold steady: use both hands; rest elbows
- Even lighting: avoid hard shadows
- Plain background: the document on a contrasting colour helps edge detection
- Distance: fill the viewfinder with the document; not too close, not too far
- Glare: avoid shooting directly at glossy paper under bright light
OCR happens server-side
Once uploaded, OCR runs on the server (typically within 30 seconds). The on-device capture pipeline doesn't OCR locally — that keeps the app fast and battery-friendly.
If you want offline OCR (rare), the on-device classification feature is closer to what you want.
