Clever AI Humanizer vs NeuralWriter

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.

NeuralWriter is a set of writing, image, and text-analysis tools available on the web, through a Chrome extension, and by API. Its writing tools cover paraphrasing, prompt generation, translation, summarization, word counting, and headline generation. The paraphraser has Light, Medium, and Hard modes and accepts up to 10,000 characters; its API page lists 30 supported languages. The prompt generator creates prompts for ChatGPT and GPT models with the same character limit and language count. Summarization accepts up to 10,000 characters and allows output from 20% to 90% of the source. The word counter accepts up to 25,000 characters and reports readability measures. An AI detector compares five engines, highlights sentences, and gives a consensus verdict without sign-up. Image tools include generation and upscaling, with listed resolutions through 8K and 4K respectively. The free online tools plan costs nothing.
