The Problem
Office workers and students need to quickly digitize paper documents. Standard scanning apps only take photos without recognizing text, making it difficult to search and edit content afterward.
The Solution
PDFAI Scan combines camera scanning with AI OCR to recognize text in documents, supporting export to multiple formats (PDF, DOCX, PPTX). Automatically detects document edges, corrects perspective, enhances image quality, and recognizes content accurately.
Technology Used
- Frontend: Native iOS (Swift)

- Camera: AVCaptureSession with auto-detect document edges
Results
