AI text humanizer that rewrites AI-generated content to bypass detection tools
What is Undetectable AI?
Undetectable AI is a web-based platform that detects AI-generated text and transforms it into human-sounding content. Founded in 2023 by Bars Juhasz, Christian Perry, and Devan Leos, the bootstrapped company has grown to over 18 million users since its public launch in May 2023, making it the most widely used AI humanizer tool on the market.
The platform works in two stages. First, it analyzes submitted text and provides detection scores across multiple AI detection engines including GPTZero, Copyleaks, Originality.ai, and Turnitin. Then its humanizer engine rewrites the flagged content to read more naturally. Users can choose between "More Readable" and "More Human" modes and select purpose-specific settings for General, Essay, Email, or Marketing content. Independent testing shows bypass rates between 72-87% depending on the detector, with strongest performance against GPTZero.
Beyond the core humanizer, Undetectable AI bundles several productivity tools including an AI Essay Writer, AI SEO Writer, AI Job Application Bot, and Human Typer. The platform supports multilingual detection and humanization, though English content produces the most reliable results.
Pricing starts at $9.99/month for 10,000 words after a free 250-word trial. Higher-volume plans scale up to $49/month for heavier usage, with custom options available for enterprise needs. The company offers a money-back guarantee if humanized content gets flagged as AI-generated.
