About
SafePrompt - AI Prompt Injection Detector
Protect yourself from hidden text injection attacks that manipulate AI assistants like ChatGPT, Claude, Gemini, and Perplexity.
WHAT IS HIDDEN TEXT INJECTION?
Attackers embed invisible text on web pages using CSS tricks (white text on white background, zero opacity, tiny fonts). When you ask an AI to
analyze a page, it reads this hidden text and follows the attacker's instructions instead of helping you.

• White-on-white hidden text

• Off-screen positioned content
• Microscopic font sizes
• Display:none elements with suspicious content
