ScanJá transforms your cell phone into a document scanner. Point the camera, and the app finds the edges, straightens the page, and generates a clean PDF, ready to send via WhatsApp or email.
It's useful for everyday use:
• ID cards, driver's licenses, CPF (Brazilian tax ID), and proof of address for banks, registrations, or job applications
• Contracts, receipts, and invoices
• Prescriptions and medical exams
• School and college work, notes, and books
📸 Automatic scanning
Edges are detected automatically, perspective is corrected, and filters make the paper white and the text sharp. Scan multiple pages in a row and combine them into a single PDF. You can also import photos from your gallery and PDFs.
🖋️ Sign PDFs on your phone
Draw your signature, position it in the right place on the document, and share it in seconds.
📁 Everything organized
Folders and search to find any document instantly. It has a dark mode.
🔒 True Privacy
No registration or login required. Taking photos, cropping, filtering, signing, and generating PDFs happens 100% on your phone and even works in airplane mode. Your documents are stored only on your device.

How Text Reading works: when you tap the button, the image of that page is sent over the internet to our server, which checks the signature and uses Google's Gemini AI to read the text. The image is not saved: it only passes through the server and is discarded as soon as the text returns. Without internet, the app reads the text using the phone's own engine.
