Detect AI Watermarks

Detect AI Watermarks is a free, powerful, and privacy-first online tool designed to scan your text for hidden AI watermarks, invisible Unicode characters, and zero-width spaces. As AI models increasingly embed concealed markers into generated content, these invisible characters can easily break database inserts, corrupt JSON payloads, disrupt website layouts, and cause accessibility issues. Our tool helps you identify and clean these hidden elements instantly. Why You Should Choose Our Tool: 100% Browser-Based & Private: All scanning and cleaning happen entirely on your device. We never upload or store your text on our servers, ensuring complete data privacy. Instant Detection: Simply paste your text from any AI tool (like ChatGPT, Claude, or Gemini) and our scanner immediately highlights all hidden characters. One-Click Cleaning: Easily remove all detected invisible elements to get a clean, safe version of your text ready for publishing or coding. Comprehensive Unicode Scanning: We check for over 30 types of hidden characters, including zero-width spaces, special spaces, byte-order marks (BOM), and directional marks. Image Metadata Stripping: Beyond text, our platform also allows you to strip EXIF, XMP, and GPS metadata from your images. Who is it for? Developers: Debug and prevent API errors or database issues caused by invisible characters. Publishers & Content Creators: Ensure your articles are clean and properly formatted before publishing. Educators & Students: Check documents for hidden text or maintain academic integrity. Security Professionals: Inspect documents and text for hidden steganography or tracking markers.
