## 1. What is QuickScan?

QuickScan is a native iOS document scanner and PDF maker application developed by Das Group LLC. It converts physical documents, identification cards, receipts, contracts, and business cards into professional, high-resolution PDF and image files in approximately 3 seconds.

QuickScan operates on a strict **100% on-device processing model**. All edge detection, perspective distortion correction, shadow and background removal, OCR text recognition, document classification, and PDF compilation execute locally via Apple's native Vision, CoreImage, NaturalLanguage, and PDFKit frameworks. No document images, extracted text, or metadata are ever transmitted to external servers or cloud services.

## 2. Who is QuickScan For?

- **Consultants & Independent Contractors:** Quickly scan signed agreements, contracts, statements of work (SOWs), and invoices on-site to send clean PDFs immediately to clients.
- **Field Workers & Tradespeople:** Capture work orders, permits, receipts, and delivery receipts directly on job sites without requiring Wi-Fi or cellular service.
- **Legal & Compliance Professionals:** Digitize sensitive client documents, court forms, and identification with complete privacy assurance (zero third-party cloud exposure).
- **Business Travelers & Freelancers:** Digitize business cards at conferences, organize travel receipts for expense reporting, and sign agreements on the go.
- **Privacy-Conscious Individuals:** Users seeking an ad-free, account-free alternative to cloud-based scanner apps that monetize user data or upload documents to remote servers.

## 3. Key Problems Solved

1. **Eliminating Scanner Clutter & Slow Hardware:** Replaces bulky flatbed scanners and office multifunction copiers with a 3-second camera workflow.
2. **Preventing Blurry, Unprofessional Scans:** Traditional camera photos suffer from angled perspective distortion, desk clutter, shadows, and low contrast. QuickScan automatically straightens corners, crops out desk surfaces, removes shadows, and enhances text clarity.
3. **Protecting Document Privacy:** Unlike cloud-based document scanners that require accounts and upload scans to remote servers, QuickScan processes everything on-device.
4. **Instant Digitization & Searchability:** Scanned pages are made searchable and copyable via built-in Apple Vision OCR without requiring desktop software.
5. **Frictionless Document Signing:** Allows users to create, store, and position handwritten digital signatures directly on scanned contracts without third-party electronic signature subscriptions.

- **Perspective & Keystone Correction:** Corrects angled captures into flat, rectangular document pages.
- **Background & Desk Removal:** AI removes busy background surfaces (wood tables, countertops, carpets) cleanly around document borders.
- **Text Clarity Enhancement:** High-contrast filtering and adaptive binarization to make faint text, receipts, and handwritten ink legible.
- **Batch Scanning Mode:** Scan multiple pages sequentially in a single session and compile them into a single multi-page PDF.

### B. ID & Identification Mode
- Specialized preset for scanning driver's licenses, passports, health insurance cards, credit cards, and badges.
- Auto-aligns both front and back sides into clean single-page PDF or image records.

### C. On-Device OCR Text Extraction (Pro)
- Powered by Apple's native Vision framework.
- Extracts editable and copyable text from scanned documents, receipts, invoices, and business cards.
- Allows copying extracted text to the clipboard or searching within exported PDFs.

### D. AI Document Classification & Smart Entity Extraction
- Uses Apple's NaturalLanguage framework to automatically analyze OCR text and classify documents into 10 structured types:
  1. `Receipt`: Identifies store names, itemized lines, transaction dates, subtotal, tax, and total amounts.
  2. `Invoice`: Detects billing details, due dates, invoice numbers, remit addresses, and total amount due.
  3. `Contract`: Detects legal agreement terms, clauses, parties, effective dates, and signature lines.
  4. `ID Document`: Detects driver licenses, passport formats, date of birth, expiry, and ID identifiers.
  5. `Letter`: Recognizes correspondence, formal greetings, sign-offs, and dates.
  6. `Form`: Detects application forms, field layouts, checkboxes, and required signature zones.
  7. `Report`: Analyzes structured business reports, summaries, and bulleted findings.
  8. `Medical Record`: Identifies prescriptions, clinical notes, patient names, and clinic information.
  9. `Bank Statement`: Identifies account identifiers, deposit/withdrawal tables, and statement periods.
  10. `Tax Document`: Detects W-2, 1099, IRS forms, employer IDs, wages, and deductions.
- Automatically extracts structured metadata entities:
  - Dates (`NSDataDetector`)
  - Monetary amounts and currencies (`Regex`)
  - Email addresses (`Regex`)
  - Phone numbers (`NSDataDetector`)
  - Personal & organization names (`NLTagger`)
  - Street addresses (`NSDataDetector`)

### E. Digital Signatures
- Draw custom handwritten signatures directly on device with Apple Pencil or finger.
- Save signatures securely in local storage.
- Position, resize, and apply signatures anywhere on scanned PDFs before sharing.

### F. Multi-Format Export & Sharing
- High-quality PDF export (Standard, Compact, or Lossless).
- JPEG and PNG export options.
- Share via standard iOS Share Sheet: AirDrop, Mail, Messages, Files, Google Drive, Dropbox, iCloud Drive, or print via AirPrint.
