AI rewriter and humanizer with Basic and Stealth modes for different kinds of writing

## About AI Undetectable

AI Undetectable is an AI rewriter and humanizer designed to help AI-generated writing pass AI detectors. Paste a draft, choose Basic or Stealth, and select a writing type: general writing, essay, article, marketing material, or story. The editor keeps the original and rewritten text side by side for review. Text and image detection are separate tools, with access depending on the plan.

The humanizer accepts up to 750 words per request. Basic uses one credit per input word and Stealth uses two. The editor and selected full-essay examples are public without signup; running the tools requires a 3-day trial followed by a paid subscription. Monthly plans start at $9.99. Detector outcomes vary; no tool can guarantee every detector result.
