What is AI Humanize?
AI Humanize is a web tool that rewrites machine-generated text so it reads more like something a person wrote. You paste text, try a sample or upload a .txt, .md, .pdf or .docx file of up to 10 MB, then pick a mode and a style. Basic mode performs one rewrite per request, while Autopilot repeats the rewrite several times. Style presets include General, Academic, Blog, Formal and Informal, plus options to expand or simplify the passage. Two locks protect parts of the input: one keeps chosen SEO keywords unchanged and the other preserves quoted material. The site also has an AI Detector that returns a score, a rewrite history, an API and an interface translated into more than twenty languages. Without a subscription each request is capped at 200 words; paid plans raise monthly and per-request limits.
Key Features
Basic and Autopilot Modes
Runs a single rewrite in Basic mode, or rewrites repeatedly in Autopilot mode; Autopilot Pro is listed among the paid plan features.
Writing Style Presets
Adapts the output to General, Academic, Blog, Formal or Informal registers, and can lengthen or simplify a passage.
Keyword and Citation Locks
Leaves the SEO keywords you list untouched and keeps quoted content as written during a rewrite.
File Upload
Imports text from .txt, .md, .pdf and .docx files up to 10 MB instead of pasting.
AI Detector
Scores a text for how likely it is to be AI-written; plans set how many detections are allowed per day.
