Paper is everywhere
A signed contract on the desk. A receipt in your wallet. A page from a book you need for tomorrow.
And "Can you send me a copy?" usually means a blurry photo, a crooked page and a file nobody can find later.
Now picture this instead: point your phone, snap, done. ✅ A clean, cropped PDF, ready to share.
That's what Scan Documents in ScanMint AI is for.
How to scan a document with ScanMint AI: step by step
1. Open ScanMint AI and tap "Scan Documents"
You'll find Scan Documents under Quick Tools on the home screen. Tap it to open the scanner.
2. Point your camera at the document
Hold your phone flat above the page so the whole page is in view. Turn on Flash in low light, and use Filters to choose a colour mode.
3. Tap the shutter and let the app find the edges
ScanMint AI detects the edges of the page and crops away the background, such as the desk, keyboard or table. To add more pages, keep snapping: the scanner stays ready for the next one.
4. Adjust, filter or rotate the page
Review each page and polish it:
Adjust: moves the corners of the page. Use it when the crop missed an edge.
Filters: improves contrast and colour. Use it when text looks grey or faded.
Rotate: turns the page. Use it when the page is sideways or upside down.
Retake: shoots the page again. Use it when a page is blurry.
Delete: removes a page you don't need.
5. Tap Done to save it as a PDF
ScanMint AI turns your pages into a high-quality PDF and confirms: "Document scanned and saved as PDF." You'll see the file name, number of pages, scan date and file size.
6. Share it to any app
Tap Share to send the PDF to WhatsApp, Mail, AirDrop, Gmail or any app on your phone.
7. Find every scan in your History
Every document appears under Recent History on the home screen, and the Analytics Overview shows your scans over time. Tap a scan to see its preview and details, or to Copy, Share, View or Delete it.
8. View, print or download your PDF
Open the PDF to Print, Download or Delete it. Downloaded files are saved to the ScanMint AI/PDFs folder, and all your files are in the PDF Workspace.
💡 Tips for a sharper scan - Put light paper on a dark surface so the edges stand out. - Use daylight or Flash, and avoid shadows from your phone or hand. - Hold the phone parallel to the page, not at an angle. - Flatten folded pages before you snap.
