Is WriteHuman’s AI humanizer free?

Yes. WriteHuman offers a free plan you can use without signing up, with a monthly word allowance. The free tier covers most casual users, and paid plans unlock higher monthly limits, longer inputs per request, and access to our advanced humanizer modes. You can try the humanizer at the top of the page without entering any payment details.

What kinds of writing does WriteHuman work best on?

WriteHuman handles long-form and short-form alike: blog posts, articles, marketing copy, landing pages, emails, newsletters, product descriptions, social posts, and reports. Longer inputs give the rewriter more rhythm to vary, so paragraphs and full pages typically read more naturally than one-line snippets. Formal and casual registers are both supported; the rewriter keeps your tone where you set it.

Which AI models does the humanizer work with?

All the major language models writers use today. That includes OpenAI GPT-5 and GPT-5.5, Anthropic Claude Opus 4.7, Sonnet 4.6, and Haiku 4.5, Google Gemini 3 Pro and 3.1 Pro, xAI Grok 4, DeepSeek V3 and V4, and Alibaba Qwen 3.6. Coverage extends to earlier versions of each family. As new models launch, the humanizer is retrained so the catalog stays current.
