What it is

Clever AI Humanizer is a web-based tool for revising AI-assisted drafts, with controls for tone and length. Its Normal and Clear & Structured styles suit different kinds of writing, and the site lists English, Spanish, and Portuguese support. A free plan costs nothing, has no fixed monthly word allowance, and permits up to 3,000 words per request, subject to service availability. A free account stores results in content history. The site also offers an AI Detector, AI Paraphraser, and Grammar Checker; its free detector and humanizer widgets can be embedded on websites using a script or iframe and have light, dark, or automatic themes. The maker says those widgets work with WordPress, Webflow, Ghost, and plain HTML. Submitted text is sent to external AI and LLM providers for processing; the privacy policy says it is not used to train or fine-tune models and is kept, along with outputs, for 30 days. The service advises against submitting confidential or special-category personal data. Users must be at least 18, and public API access is listed as coming soon with a waitlist.
