What HumanizerAI is
HumanizerAI rewrites AI-generated text from tools such as ChatGPT, Claude and Gemini to read more naturally while preserving meaning. Its Light, Medium and Bypass modes offer different degrees of rewriting; the site notes that Bypass may substantially shorten and simplify text. Other listed tools include an AI detector, paraphraser, grammar checker, summarizer, word counter, plagiarism checker and paragraph rewriter. The features page says quotations, citations, dialogue, formulas and LaTeX notation are preserved. HumanizerAI cautions that detector results differ by text type and detector and does not promise a particular result. It is available on the web, as an extension and through an API. API keys require a Pro or Business plan, and API requests can process up to 10,000 words subject to plan-specific rate limits. The free Chrome extension offers 50 daily scans for AI-generated posts on X and can hide AI content from the feed. Paid plans start at $10 a month, billed $120/year, for 10,000 words/month. Submitted text may be temporarily stored and processed by third-party AI services.
