A static, rule-based scanner for indirect prompt-injection payloads concealed inside PDF documents — micro fonts, off-page text, white-on-white, hidden layers, metadata exploits, and more. Everything runs in your browser. Files never leave this tab.
Heuristic, not ground truth — a clean report is not a safety guarantee. False positives possible with academic watermarks or tiny footnotes. Encrypted PDFs have limited coverage. Color detection is approximate. Overlap detection only handles solid fills, not images.
