Transform AI-generated text into natural, human-sounding content that passes Turnitin, GPTZero, and other AI detectors.
UndetectedGPT is an AI content platform that transforms machine-generated text into natural, human-like writing. It offers three core tools: an AI Humanizer that restructures existing AI text, a Ghost Writer that generates original undetectable content from scratch, and a built-in AI Detector to verify results before publishing. The platform works with content from ChatGPT, Claude, Gemini, and other LLMs, targeting students, content creators, and professionals who need their AI-assisted writing to read naturally.
UndetectedGPT is an AI content platform with three core tools: an AI Humanizer that transforms AI-generated text into human-sounding writing, a Ghost Writer that creates original undetectable content from prompts, and a built-in AI Detector that checks your text against major detection systems before you publish.
The platform is designed to bypass Turnitin, GPTZero, Originality.ai, ZeroGPT, Copyleaks, Scribbr, and Grammarly's AI detection. However, no tool can guarantee 100% undetectability since detection algorithms are constantly updated.
UndetectedGPT works with content generated by ChatGPT (GPT-3.5, GPT-4, GPT-5), Claude, Google Gemini, Llama, and other major language models.
Yes. UndetectedGPT offers a free tier with limited daily usage so you can test the tool before committing to a paid plan. Paid plans start at $19.99/month for the Starter tier.
The platform supports humanization in over 100 languages, but it is optimized for English. Non-English content may see reduced quality and lower bypass rates, so testing with your target language first is recommended.
Most text is processed in 3 to 10 seconds. Longer documents may take up to 30 seconds but rarely longer.
The AI Humanizer takes existing AI-generated text and transforms it to sound human. The Ghost Writer generates new, original content from a prompt with human writing patterns already built in, so no separate humanization step is needed.
