Understand the signals.
Keep the final say.
Writing can feel formulaic without being AI-generated. Our free AI text classifier makes the patterns visible, so you can review your draft with context instead of relying on a percentage.

GOOD TO KNOW
A few clear answers.
What this tool does.
And what its results mean.
What is an AI text classifier?
An AI text classifier examines writing for patterns associated with AI-generated text. CocoHumanizer’s free tool checks sentence rhythm, stock phrases, formal transitions and repeated openings. It is a transparent style review, not a trained authorship detector.
Is the AI text classifier completely free?
Yes. No account, subscription or credits are needed. Check up to 2,500 words and 25,000 characters at a time, as often as you like. These checks do not use your AI Humanizer word allowance.
Can this tell me for certain whether text was written by AI?
No. Both people and AI use similar language, so style patterns cannot prove who wrote a passage. This tool does not provide an AI probability or a verified accuracy score. Do not use its results alone to make academic, employment or disciplinary decisions.
Is my text uploaded or saved?
The classifier runs in your browser. It does not upload your passage for analysis or save it in an account. Closing or reloading the page clears the text. Standard site analytics, where enabled, do not receive your passage.
Which languages and text lengths are supported?
This version is designed for English prose. Use at least 50 words; 100 or more words and five complete sentences give a more useful review. Other languages, code, lists and very short passages can produce misleading signals.
Does a low result mean my text will pass other AI detectors?
No. Few formulaic patterns does not mean human authorship, and this result does not predict scores from Turnitin, GPTZero or other detectors. Each tool uses its own methods.
How is this different from the AI Humanizer?
The classifier reviews writing patterns without changing your text. The AI Humanizer rewrites a draft for a more natural voice. It is a separate tool with its own Free and Pro word allowances.
