How It Works

1

Paste

Paste AI-generated text from ChatGPT, Claude, Gemini, Copilot, or any other AI tool.

2

Clean

The tool strips hidden whitespace, normalizes quotes, removes zero-width characters and tracking parameters.

3

Copy

Cleaned results are auto-copied and ready for immediate use. No trace of AI fingerprints.

What It Cleans

Hidden Characters

Zero-width characters, soft hyphens, directional marks, and non-breaking spaces that AI tools embed invisibly.

Smart Quotes & Dashes

Normalizes curly/smart quotes to straight quotes, converts em dashes and en dashes, and fixes Unicode ellipses.

Tracking Parameters

Removes AI-specific URL tracking parameters like source=chatgpt, utm_source=openai, and similar markers.

Homoglyphs & Artifacts

Detects and replaces suspicious homoglyph characters and Unicode artifacts that fingerprint AI-generated content.
