Partial The page-level tools (merge, split, compress, sign, redact) are standard and wrap existing libraries, but true in-place text, image and table editing of existing PDFs is a hard layout-fidelity problem.
What it would actually take: Build on PDFKit or PDFium for rendering and page operations, Apple Vision or Tesseract for OCR, and an on-device model for scan cleanup. The hard part is editing content streams while preserving fonts, text reflow, and layout in arbitrary PDFs, which needs a PDF internals specialist and extensive edge-case testing.
