Could you build this?
Partial While wrapping standard mobile OCR and PDF libraries is doable, production-grade 100% offline edge detection, perspective transformation, and multi-language OCR on diverse hardware requires non-trivial computer vision tuning.
What it would actually take: A production implementation requires native mobile apps (Swift/Kotlin or Flutter/React Native) leveraging OpenCV and ML Kit/Tesseract or Apple Vision for on-device document detection and OCR. The hard parts are real-time edge detection and perspective warping across irregular lighting/backgrounds, high-accuracy table and receipt key-value extraction completely offline on constrained mobile memory, and PDF generation with digital signature hashing. Achieving smooth 60fps camera feed processing and fast local inference requires specialized mobile computer vision and low-level performance optimization.
