Could you build this?

Partial A native Mac UI for filling forms, signing, and running OCR is buildable with Apple frameworks, but keeping PDF forms intact and digital signatures valid requires precise handling of the PDF spec that vibe coding is unlikely to get right alone.

What it would actually take: Build a native macOS app in Swift on PDFKit and Apple's Vision framework for on-device OCR. The hard part is editing PDFs without breaking AcroForm fields or existing cryptographic signatures, which means incremental-update writing and PAdES-compliant signing, possibly via a library such as pdfium or a commercial SDK. Testing against a large corpus of real-world PDFs and a developer who knows the PDF internals is what a robust version requires.
