AI detector

Check whether text was written by AI. Our detector gives a 0–100 liveliness score and shows the concrete markers of AI — clichés, bureaucratese, repeats, flat rhythm — with their exact spot in the text. Free and unlimited, online, no signup. We don't store your text.

What the AI checker looks for

We don't guess “AI or human” — we count concrete markers of careless machine text. Well-written text passes, even if a model wrote it.

Clichés and filler

“In today's world”, “it's important to note” — phrases models repeat automatically.

AI traces and markers

Bureaucratese, obsessive word repeats, monotone rhythm, “not X but Y” antitheses — each shown in place.

Score and AI percentage

A 0–100 liveliness score and a verdict. The lower the score, the more AI traces in the text.

Found AI? Humanize the text

The check shows what's wrong. Humanization fixes it: it rewrites the flagged spots in living language, keeping meaning and voice. The before/after score is measurable.

FAQ

How do I check text for AI for free?
Paste text and hit “Check”. A liveliness score, a verdict and a marker breakdown — no login, no limits. We don't store your text.
What are the signs of AI-written text?
Clichés (“in today's world”), bureaucratese, obsessive repetition, monotone rhythm, “not X but Y” antitheses. The detector counts them and highlights each.
How accurate is the AI detector?
It's deterministic: it counts concrete markers rather than guessing. Clusters of findings decide the verdict, so a single word never sinks a text.
Is it a free AI content detector, like Copyleaks or GPTZero?
Checking is free and unlimited, no signup. Unlike a plain verdict, we show the concrete markers and their spot, so the breakdown is useful even for human text.
