WriteHuman
AI humanizer that rewrites machine-generated text in a more natural style, with a built-in AI detector.
WriteHuman is an AI humanizer that rewrites text produced by chatbots so that the rhythm, vocabulary and sentence structure vary more, while the meaning stays the same. WriteHuman also scores text for AI probability. WriteHuman is used by pasting a draft into the web editor, the Chrome extension or the mobile apps.
Best for Marketers, freelancers and agencies who edit AI-assisted drafts and want rewriting and detection checks in one account.

What is WriteHuman?
WriteHuman is a rewriting tool that takes text from assistants such as ChatGPT, Claude or Gemini and restructures it so it reads less mechanically. Rather than swapping individual words, it changes sentence length, phrasing and cadence; the site's own example splits one long sentence into two shorter ones and replaces inflated wording with plainer terms. More than forty languages are accepted. A detector is included that assigns an AI probability to every sentence, and a separate checker examines images. Beyond the website there is a Chrome extension that also offers spelling, grammar and style suggestions, apps for iPhone, iPad and Android, a REST API and an MCP connection for AI agents. Plans are named Free, Basic, Pro and Ultra and differ in monthly requests, words per request and output variations.
