Questions? Answered
Everything you need to know about HumanAI and how it works.
How accurate is HumanAI's AI detector?
Our detector achieves 98% accuracy by analyzing multiple signals: perplexity scores, burstiness patterns, semantic coherence, and structural markers. We continuously train on the latest AI models including GPT-4, Claude, and Gemini.
Will the humanizer produce awkward or grammatically incorrect text?
No. Unlike Undetectable.ai or StealthWriter, which often produce stilted text, our humanizer uses advanced rewriting that preserves meaning while adopting natural human writing patterns — varied sentence length, conversational phrasing, and contextual flow.
Can HumanAI detect text from all AI models?
Yes. We support detection of text generated by GPT-3.5, GPT-4, GPT-4o, Claude 2/3, Gemini, LLaMA, and other major LLMs. We update our models regularly as new AI models are released.
Is HumanAI free to use?
Basic detection and humanization are free with generous limits (10,000 characters per check). Premium unlocks all 15 tools, unlimited text length, multi-language support, batch processing, and API access for $9.99/month.
Does it work with languages other than English?
Yes. HumanAI supports 27+ languages including Spanish, French, German, Arabic, Chinese, Japanese, Portuguese, and more. Most competitors only support English.
Can I integrate HumanAI into my own application?
Yes. Premium subscribers get access to our REST API for both AI detection and humanization. The API supports batch processing, detailed reports, and webhook callbacks for async processing.
