About ZeroAliens

What it is

ZeroAliens is a free detector of AI-written text. It analyzes a text with statistical signals (sentence variation, repeated vocabulary, typical filler phrases) and returns an overall percentage, a paragraph-by-paragraph analysis and the signals that explain it.

How it works

The analysis runs on our own server, without sending your text to external AI services. It works in Spanish, English, French, Italian, Galician and Portuguese.

Its limits

It is an estimate, not proof. It can fail with short, very formal, translated or second-language texts. It should never be the only basis for penalising anyone.
