ChatGPT watermarks are invisible characters or patterns that AI providers may embed in generated text to identify it as AI-created content. These can include zero-width spaces, zero-width joiners, and other non-printable characters that are invisible to the human eye but detectable by software.
This tool identifies and strips non-printable characters, zero-width spaces, and other invisible markers from your text. The "Clean Text" tab provides a version of your content with these characters removed, effectively eliminating potential watermarks while preserving the visible content.
This tool is for educational and analytical purposes. While removing watermarks from text is generally not illegal, you should always respect the terms of service of the platforms you use. This tool should be used responsibly and ethically. Always ensure you have the right to use and modify content as needed.
The usage rights for the content itself are determined by its source. If you're using AI-generated content, check the terms of service of the AI provider to understand your rights. This tool only helps you analyze and clean text - it doesn't change the underlying ownership or usage rights of the content.
No. This tool operates entirely in your browser. Your text is never sent to our servers or stored anywhere. The analysis and cleaning happen locally using JavaScript, ensuring your content remains private and secure.
Copy text from any source and paste it into the text area. The tool works best with content that might contain hidden characters, like text from ChatGPT, Claude, or other AI systems.
Click the "Analyze Text" button to see a detailed breakdown of all characters in your text. Hidden characters will be highlighted and shown with their Unicode values for easy identification.
Use the "Copy" buttons to save the clean version of your text or the Markdown content to your clipboard. The copied text will be free from invisible watermarks and ready to use.
Hover over any character in the analysis view to see detailed information about it, including its Unicode value and hexadecimal representation.
ChatGPT and other AI models may include invisible watermarks in generated text. These watermarks are subtle patterns in word choice or invisible characters embedded within the text that can identify content as AI-generated, even when not explicitly stated.
According to recent research, ChatGPT models seem to insert specific patterns that function as "signatures" in the text they produce. While OpenAI has not officially confirmed all watermarking techniques, analysis suggests multiple methods are in use.
AI text watermarks typically work in two main ways:
These watermarks use predictable patterns in word choice. The AI may slightly favor certain words over others in a way that's imperceptible to humans but detectable with statistical analysis. RumiDocs researchers found evidence suggesting ChatGPT models may select certain tokens in a way that creates a statistical fingerprint.
Some watermarks use zero-width spaces, zero-width joiners, or other invisible Unicode characters inserted between visible characters, creating a pattern that serves as a digital signature without being visible to human readers.
According to Medium's AI Disruption publication, these watermarking techniques can persist even after text has been rewritten or edited, potentially allowing tracing of AI-generated content across multiple versions.
Recent investigations have revealed interesting insights about ChatGPT watermarks:
These watermarks can be detected through:
The implications of these watermarks are significant for users who rely on AI-generated content for legitimate purposes. Schools, employers, and publishers increasingly use AI detection tools that may flag watermarked content, potentially causing issues for users even when the use of AI assistance is permitted.
While watermarking serves legitimate purposes like combating misinformation, there are valid reasons why users might want to remove these watermarks:
