Undetectable AI
Undetectable AI is a platform that humanizes AI-generated text so it passes major AI detectors while remaining high quality and legible. It combines an AI humanizer with an AI detector, writing level matching, and watermark and future-proofing features. Plans include unlimited detection, API compatibility, and an unlimited Human Auto Typer, with a small free trial and paid word-based subscriptions.
What is Undetectable AI?
Undetectable AI is a writing platform that solves a specific modern problem: AI-generated text is increasingly detectable by automated tools, which can cause problems for students, marketers, and professionals who rely on AI assistance. Undetectable AI combines two core tools in one service. The AI Humanizer rewrites AI-generated content so that it reads naturally and passes major AI detectors while keeping the meaning, quality, and legibility of the original text. The AI Detector checks content against leading detection models so users know whether text will be flagged before they publish it. The platform is rated number one on Forbes for AI humanizers and detectors, and it has been featured by major outlets including Business Insider, Fox, NBC, CBS, and Mashable, with more than 24 million total users and tens of thousands of new users joining weekly. Beyond the core humanizer and detector, Undetectable AI includes writing level matching so output can be tuned to a specific education or professional level, watermark and future-proofing that helps content stay undetectable as detection models evolve, and an unlimited Human Auto Typer that types humanized content automatically. All plans include unlimited AI detecting, and the platform is API compatible, which lets businesses integrate humanization into their own content pipelines. A Chrome extension brings the tools directly into the browser for on-the-go rewriting. Pricing is based on monthly word allowances, from a 10,000-word plan at $9.99 per month down to $5 per month when billed annually, up to 50,000-word plans and custom business pricing with non-expiring credits and white labeling. New users get a free trial limited to 250 words to test the service before committing. The platform's development is informed by continuous testing against the latest detection models, which is why the humanizer remains effective as detection technology evolves. For teams producing content at scale, the API and white-label options turn humanization into an automated pipeline step rather than a manual copy-paste workflow, and the business plans with non-expiring credits remove the monthly word-count pressure. The Chrome extension covers casual users who want to humanize text inside their browser, while the money-back guarantee de-risks the purchase decision. With millions of active users and features across major media outlets, Undetectable AI has established itself as the category standard for AI text humanization.
