Frequently Asked Questions

Everything you need to know about our AI Text Humanizer — answered clearly and honestly.

An AI text humanizer rewrites AI-generated content so it reads like it was written by a real person. It does this by varying sentence structure, replacing repetitive vocabulary, adjusting rhythm and pacing, and introducing natural imperfections that human writers use — making the text undetectable by AI content detection tools.
Yes. Our tool achieves a 99% bypass rate on Turnitin's AI writing detection. We run thousands of automated tests weekly against Turnitin, GPTZero, Originality.ai and others to ensure our output consistently achieves human-level scores. However, no tool can guarantee 100% results in every case, so we recommend always reviewing the output yourself before submitting.
No. Our humanizer is specifically designed to preserve 100% of the original meaning, arguments, and key information. It only changes how ideas are expressed — not what is being said. The Academic mode is particularly careful to retain technical terminology and scholarly tone while restructuring sentences.
Our humanizer works on text generated by any AI tool — including ChatGPT (GPT-4, GPT-4o), Claude (all versions), Google Gemini, Microsoft Copilot, Llama, Mistral, Perplexity, and any other language model. The source of the AI text makes no difference to the effectiveness of the humanization.
Free users can humanize up to 1,500 words per session with unlimited sessions. For longer documents like full dissertations, simply split your text into sections. There is no limit on how many times you can use the tool — it will always be free and unlimited.
Never. Your text is processed entirely in memory and deleted immediately after humanization is complete. We do not store, log, analyse, share, or use your content in any way. Your academic work remains completely private and confidential.
Light mode makes subtle vocabulary and minor structural changes — best for text that is only mildly flagged. Medium mode (our recommendation) provides thorough rewriting while maintaining readability. Aggressive mode performs deep structural reconstruction — ideal for heavily flagged AI content, but the output should always be reviewed for natural flow before submission.
