Frequently Asked Questions

Whitespace fingerprinting refers to the practice of AI systems embedding invisible Unicode characters (like zero-width spaces, non-breaking spaces, or BOM markers) into generated text. These invisible markers can be used to identify AI-generated content or track its origin, even though they are not visible to humans.

Simply paste your ChatGPT-generated text into CopyCleanse and click "Clean Text". Our tool automatically removes hidden whitespace characters, normalizes smart quotes to standard quotes, converts em dashes to regular dashes, removes AI tracking URL parameters, and fixes other telltale signs of AI generation. The cleaned text is then copied to your clipboard.

Yes, CopyCleanse is completely free. There are no hidden fees, subscriptions, or premium tiers. All features are available to everyone at no cost.

No. CopyCleanse processes all text entirely in your browser using JavaScript. Your text never leaves your device and is never sent to any server. We have no ability to see, store, or access any content you paste into the tool.

CopyCleanse works with text from all major AI platforms including ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Copilot (Microsoft), Bard, and others. Our cleaning algorithms detect common patterns across all these platforms.

AI systems may add invisible characters for several reasons: to aid in formatting and word-wrapping, as artifacts of their tokenization process, for potential watermarking purposes, or as byproducts of Unicode normalization. Regardless of the reason, these characters can make text look unprofessional and may trigger AI detection tools.

Smart quotes (also called curly quotes) are the curved quotation marks instead of straight quotes. While aesthetically pleasing in documents, they can cause issues in code, databases, and some platforms. They're also a common sign of AI-generated text since AI models often use them.

CopyCleanse detects URLs in your text and removes tracking parameters that identify AI sources. This includes parameters like source=chatgpt, utm_source=openai, ref=claude, and similar tracking codes. The rest of the URL remains intact, preserving any legitimate query parameters.

Yes! CopyCleanse is fully responsive and works on mobile phones and tablets. Simply paste text into the input field, tap "Clean Text", and the cleaned result will be ready to copy.

While CopyCleanse removes many technical artifacts that AI detectors look for, no tool can guarantee your text will pass all AI detection systems. AI detectors also analyze writing style, patterns, and statistical properties of text. CopyCleanse focuses on removing the invisible technical fingerprints that are dead giveaways of AI origin.
