PaperBleach is a free AI humanizer that helps you humanize AI text — turning AI-generated drafts (essays, papers, articles) into writing that reads naturally and passes AI detectors like Turnitin, GPTZero, and Originality.ai, while keeping your meaning intact. Use it to humanize AI text from ChatGPT, Claude, Gemini, and other models, and check your AI-detection score before and after you humanize.
