Optical Character Recognition (OCR) is the technology that converts images containing text into actual, editable, searchable text. Without OCR, a scanned document is just a picture—you can see the text, but you can't select it, copy it, or search for specific words.
ScanLens uses advanced neural network technology to analyze the pixels in your scanned images and identify individual characters. Unlike older OCR engines that relied on rigid pattern matching, our AI-based approach understands context, recognizes various fonts and sizes, and handles real-world imperfections like skewed text, poor lighting, and paper textures.
The result is remarkably accurate text extraction that transforms your paper documents into truly digital files. Search through hundreds of scanned pages in seconds, copy text into emails or documents, or let your computer read documents aloud. Once text is extracted, the possibilities are endless.
When you scan a document, ScanLens runs a sophisticated processing pipeline that happens entirely on your iPhone:
All OCR processing happens locally using Apple's Neural Engine. Your documents never leave your iPhone, ensuring complete privacy even for sensitive materials.
ScanLens OCR handles a vast range of languages and scripts, making it useful for international documents, academic research, and multilingual workflows:
For documents containing multiple languages—like a English textbook with Japanese annotations—ScanLens automatically detects and processes each language appropriately without manual configuration.
ScanLens achieves professional-grade accuracy on printed documents. In standardized testing against common document types, our OCR engine correctly recognizes 99.5% of characters on clean, well-lit scans of printed text.
For handwritten text, accuracy varies based on legibility. Clear handwriting typically achieves 85-95% accuracy, while messy handwriting may require manual review.
Once ScanLens extracts text from your documents, you can:
OCR (Optical Character Recognition) is AI technology that converts images of text into machine-readable text. ScanLens uses neural networks trained on millions of documents to recognize characters. The process involves image preprocessing, layout analysis, character segmentation, and deep learning recognition, achieving 99.5% accuracy on printed text.
ScanLens OCR supports over 50 languages including English, Spanish, French, German, Chinese (Simplified and Traditional), Japanese, Korean, Arabic, Hebrew, Russian, and many more. It handles both Latin and non-Latin scripts, and automatically detects multiple languages in the same document.
Yes, ScanLens can recognize handwritten text. Accuracy depends on handwriting legibility—clear handwriting achieves 85-95% accuracy, while printed text reaches 99.5%. For best results with handwriting, use good lighting and write clearly.
Yes, ScanLens embeds OCR text invisibly within PDFs, making them fully searchable. The visual appearance remains unchanged, but you can use Ctrl+F (or Cmd+F) in any PDF reader to search for any word or phrase in your scanned documents.
Yes, all OCR processing happens locally on your iPhone using Apple's Neural Engine. No internet connection is required, and your documents never leave your device. This ensures complete privacy even for sensitive documents.
