Remove AI Watermarksfrom ChatGPT Text

AI watermarks are invisible characters (like zero-width spaces) that AI tools like ChatGPT insert into generated text. These hidden markers help identify AI-generated content but don't affect readability.

Our tool scans your text for invisible characters commonly used as AI watermarks, such as zero-width spaces and ASCII control characters. It then highlights these markers and can remove them completely while preserving your original content.

No. All text processing happens directly in your browser. We don't store, log, or transmit your text anywhere. Your privacy is our priority.

We detect various invisible characters including zero-width spaces, zero-width joiners, soft hyphens, word joiners, and ASCII control characters that AI tools might use as watermarks.

No. The tool only removes invisible characters used as watermarks. Your visible text, formatting, and meaning remain exactly the same.

Yes, the free version currently has a 500-character limit per operation. Signed-in users get 1,500 characters. This helps ensure fast processing and optimal performance.

Yes! You can upload Word (.docx) documents directly to our tool. We'll scan and remove invisible watermark characters from all sections including main content, headers, footers, footnotes, and comments—all while preserving your document's formatting and layout. Processing happens entirely in your browser, so your documents remain private.

Yes! You can upload Apple Pages (.pages) documents directly to our tool. We support both modern and legacy Pages formats. We'll scan and remove invisible watermark characters from your entire document while preserving all formatting, styles, and layout. All processing happens locally in your browser, ensuring your documents stay completely private.

Your documents are 100% secure and never leave your device. All document processing happens entirely in your browser using JavaScript. When you upload a Word or Pages document, it's read and modified locally on your computer—we never send your files to any server. This means your sensitive documents, personal information, and private content remain completely confidential. Even we can't see what you're processing. This client-side approach ensures maximum privacy and security for your documents.

If you clean a document using our document uploader and then copy-paste the text into the text detection area, you might see watermarks detected. This is normal and doesn't mean the cleaning failed. Here's why: Document cleaning preserves all formatting (bold, italics, spacing, etc.) to keep your document looking identical. When you copy this formatted text, some harmless formatting characters (like special spaces or unicode formatting marks) come along. Our text detection tool, which is designed to be more aggressive, might flag these formatting characters as potential watermarks. The document itself is clean—these are just formatting artifacts from the copy-paste process, not actual AI watermarks. For best results, use the cleaned document directly rather than copy-pasting its content.
