UndetectedGPT

Getting AI drafts to read like a person wrote them is the main use of UndetectedGPT, an AI humanizer and detector that works on text from ChatGPT, Claude, Google Gemini, Llama and other major writing tools.

UndetectedGPT is built for people who want AI text to pass checks from detectors such as GPTZero, Turnitin and Originality.ai.

It has three parts.

The AI Humanizer takes existing AI text and reworks it with added details, tone changes and smoother flow.

The Stealth Writer starts from a prompt and generates new content meant to keep a distinct voice.

The AI Detector lets you check text before you use it.

You can set the tone to suit your audience and purpose, and results come back quickly.

Pricing needs a careful read.

The site is labeled free, but the core humanization and stealth writing features appear to sit behind a subscription, with word and daily credit caps on lower plans and extra cost beyond them.

Treat any promise of complete undetectability with caution, since detectors keep changing.

Check results yourself, especially for academic work.
