What this AI text detector checks

The checker reviews predictability, repeated phrasing, sentence rhythm, stylistic uniformity, and other patterns associated with AI-generated text. It returns an estimate with an explanation instead of a simple accusation.

How to check for AI writing

Paste a meaningful sample, run the check, then read both the probability and the cited signals. Longer, coherent passages usually provide more context than a headline, list, or isolated sentence.

How to interpret an AI text checker score

Treat the result as a screening signal. A high or low score cannot establish authorship by itself, so compare it with drafts, sources, edit history, and direct conversation before making a consequential decision.

Common limits of AI writing detection

Human editing, translation, formulaic writing, short samples, and mixed human-AI drafts can all change the result. The tool is useful for deciding what deserves review, not for proving who wrote a passage.

AI Text Detector FAQ

Practical answers about the check, its results, and its limits.

How can I check if text is AI generated?

Paste the passage into the AI text detector and run a check. Review the probability together with the explanation, then verify against drafts and source material if the decision matters.

Is this AI writing detector free?

Yes. A visitor can run one free check, and signing in with Google adds three more free checks under the current launch allowance.

Can an AI generated text detector be 100% accurate?

No. Every detector can produce false positives and false negatives. Results should be treated as evidence for closer review, not conclusive proof.
