Could you build this?
Partial The browser wrapper and UI are straightforward, but running offline client-side PDF rendering, docx conversion, and OCR requires complex compiled WebAssembly binaries.
What it would actually take: Requires compiling existing C/C++ or Rust libraries (such as Poppler, MuPDF, Tesseract for OCR, or pdfium) into WebAssembly via Emscripten or wasm-pack, paired with web workers to prevent UI thread blocking. The hard part is managing WebAssembly memory limits, optimizing conversion performance for multi-megabyte PDFs on client hardware, and accurately mapping complex PDF layout geometries back into structured DOCX XML. Specialized expertise in document layout heuristics, WebAssembly compilation, and PDF specifications is essential.
