Could you build this?
Partial Basic PDF viewing and annotation can be wrapped with open-source tools, but building a fully offline document processor with true text editing, redaction, and PDF-to-Word round-tripping requires complex layout engine work.
What it would actually take: A desktop shell built with Tauri or Electron integrating PDFium for rendering and Tesseract for local OCR, paired with a rich-text engine like TipTap or ProseMirror. The hardest challenge is building a true PDF layout reconstruction and patching engine that modifies existing text while preserving original fonts, encodings, and vector layouts. Requires expertise in the low-level PDF specification and native desktop file manipulation.
