Kostenloser KI-Humanisierer und Detektor.

Included in every plan, free and anonymous access too. Detector and humanizer share the same daily character quota, so you can analyze before, after or any time without paying extra.

We do not train models on your text. With Core (default), text is processed on our servers and not sent to an external AI. If you choose the optional AI model, text is sent to an external provider for rewriting — we warn you first. With an account, we only keep history items you choose to save.

Vortixy Core applies a single deterministic analysis at constant depth to any text, no matter the length or complexity. It reviews rhythm, meaning, coherence and linguistic patterns, and shows a short summary of the change while it works. Ideal for everyday use as well as academic essays or content you're about to publish.

No—and be wary of any tool that promises this. Detectors like Turnitin, GPTZero or Originality keep changing their models. What we do guarantee is meaningfully reducing the linguistic signals associated with AI and giving you text that reads like a human wrote it.

Vortixy humanizes text in 14 languages including Spanish, English, Portuguese, French, German, Italian, Dutch, Polish, Russian, Japanese, Chinese, Korean, Turkish and Arabic. Each language has its own linguistic transformation rules.

Without an account you can process up to 8,000 characters per day (maximum 3,000 per text). With a free account that rises to 15,000 characters daily (up to 10,000 per text). Pro and Max plans offer much higher limits. Full details are on the pricing page.

You need internet. Core runs on our servers without calling an external AI. If you pick the AI model, an external provider is used and the UI marks it clearly. Offline use is not supported.

Yes. Vortixy Core applies the same in-depth analysis to any text, including essays, articles, reports and professional content. Choosing the Academic or Professional tone helps you maintain the right register while removing AI markers.

Vortixy differs in three ways: 1) Core is our own local deterministic engine, not a silent GPT wrapper. 2) Built-in detector. 3) The AI model is optional with a privacy notice, not the default. Core protects sensitive data patterns during transforms.

Yes — only if you choose it on purpose. Core stays in Vortixy. The AI model uses an external provider (don’t send passwords or personal data). It’s mainly for clearer, more natural writing; we try to lower AI%, but it won’t always hit the lowest score. Free includes a daily try allowance.
