What is Undetected?
Undetectable AI is an AI-powered paraphrasing and detection tool that transforms machine-generated text into natural, human-like writing—making it undetectable by common AI content detectors. Beyond paraphrasing, it offers a built-in AI detector and a “Humanizer” mode to subtly adjust tone, syntax, and structures for enhanced authenticity .
Who can use Undetected & how?
Who Can Use It?

  • Students & Academics: Avoid false positives in AI writing detection while preserving clarity and originality.
  • Content Marketers & Bloggers: Generate SEO-optimized, authentic content that passes AI detector checks.
  • Writers & Professionals: Refine drafts for natural tone and fluency.
  • SEO and Compliance Teams: Ensure human-like text for digital visibility and regulatory alignment.

⚙️ How It Works?

  • Paste or Upload Text: Submit your AI-generated content.
  • AI Detect Mode: Scan the text using multiple detector engines (e.g., GPTZero, Quillbot, Copyleaks).
  • Humanize/Paraphrase: Click to rewrite text, adjusting tone and complexity with “Humanizer” settings.
  • Export Results: Copy or download the adjusted text.
What's so unique or special about Undetected?
  • Combined Detection & Humanization: Offers a full workflow—detect, paraphrase, and humanize in one place.
  • Multilayer Detector Integration: Checks content against multiple detectors at once.
  • Human-Like Refinement: Adds subtle errors and stylistic shifts for natural texture.
  • Free and Freemium Options: Basic use is free; premium plans offer expanded limits and advanced modes .
Things We Like
  • Fast, one-click processing with no sign-up required.
  • Freemium model offers generous access before upgrade is needed.
  • Effective at bypassing detection tools like GPTZero and Copyleaks.
Things We Don't Like
  • Over-humanization may introduce grammar or clarity trade-offs.
  • Ethical and academic misuse concerns could arise.
