Is ClearCopy free?
Yes. The text-cleaning feature is free. There is no subscription, account, or AI API requirement.
Does this remove ChatGPT’s hidden textGrain watermark?
No verified claim can be made that it does. textGrain uses patterns in generated word choices, not Unicode spaces. ClearCopy removes or changes selected copy-paste characters and optional formatting.
Is invisible Unicode always suspicious?
No. Many invisible characters are legitimate parts of languages, emoji sequences, typography, and bidirectional text. That's why advanced cleanup is optional and some joiners are always preserved.
Is my text sent to an AI server?
No. The current cleaner runs entirely in your browser. The host can still receive ordinary website-visit data and may keep access logs.
Can I use it for ChatGPT, Claude, Gemini, or human-written text?
Yes, provided you are authorized to work with the material. The character cleanup is based on Unicode, not on which tool wrote the text.
Can this AI detector tell if ChatGPT wrote something?
No. Our free pattern checker flags explainable stylistic features, not validated AI-authorship predictions. It does not run a trained classifier and gives no AI percentage. Read why.
Will it improve an AI-detection score?
We cannot predict or promise that. AI detectors and provenance watermark detectors use different techniques. This is primarily a formatting and text-hygiene tool.
Will I lose paragraphs, formatting, or special characters?
Paragraph breaks are preserved for the basic options. Some spacing changes and advanced controls may affect meaning. Compare the original and result before using your text.
Can I clean a PDF or a Word document?
Not directly in this version. Paste the text or upload a small .txt or .md file; PDF and Word file upload are not supported.
Can I use this for school or professional work?
Use it only on content you may edit. Follow your school’s, employer’s, publisher’s, or platform’s AI-use and attribution rules. Cleaning does not remove disclosure obligations.
