Most AI models (like ChatGPT, Claude, and Gemini) embed invisible Unicode characters and hidden watermarks into the text they generate. You can't see them, but they can track your content or cause bugs in your code. Detect AI Watermarks is a free, privacy-first tool that reveals what's hiding in your text. Why use it? • Local Processing: We scan text directly in your browser. Nothing is ever uploaded to a server. • Instant Detection: Highlights zero-width spaces and hidden markers immediately.
