Could you build this?

Partial Rendering pages to images, OCR, and text search in the browser are buildable, but guaranteeing that redaction is actually secure requires careful verification that a vibe-coded tool may get wrong.

What it would actually take: The stack would use pdf.js or pdf-lib for rendering and page rebuilding, with a client-side OCR engine like Tesseract.js to scan the output for covered text. The hard part is proving the redaction is irreversible (no hidden text layers, metadata, or leftover objects) and testing against adversarial PDFs. This calls for security engineering and PDF-format expertise, and a rigorous test corpus.
