AIHumanize.com addresses a narrow but persistent problem: content drafted by language models that reads flat or gets flagged as machine-written. The interface is a plain text box with a file upload option, two model families shown on the page (Falcon and Maestro, each in multiple versions), and a writing-style selector. After rewriting, you can run a built-in checker that reports signals such as perplexity, sentence-length variation, and length normality — the same statistical traits detectors use to judge whether text is human. The company has since launched a Version 2 of its models and claims a 99.8% detector pass rate across more than 1.28 billion words processed monthly.
The product bundles two jobs that usually require two subscriptions. The humanizer rewrites your text, and the checker estimates how AI-like it still looks, supporting PDF, Word, and plain-text inputs and claiming coverage of output from ChatGPT, GPT-3.5/4, and Gemini. The site also emphasizes SEO friendliness — it keeps important keywords rather than substituting odd synonyms — and avoids introducing grammar errors or misplaced vocabulary, which are the two things that tend to expose machine-rewritten copy in a search context.
On pricing, there is a genuine free entry point: the site states you can rewrite up to 400 words at no cost, and the input field accepts up to 21,000 words per run. Paid plans are promoted on the Pricing and Earn pages for heavier volume and additional models. Because the model lineup and credit structures change quickly, treat specific prices as something to confirm on the site rather than a fixed figure.
