AI Content Checker
Paste text to see how much it reads like AI writing. Free, no login.
What was measured
Flagged sentences
Highlighted sentences look most AI-written.
Your text is sent to a free public AI service (Pollinations) for checking, so do not paste private content. The percentage is an AI model's estimate, not a guarantee. No detector is 100% accurate, and results can be wrong both ways. Formal or edited human writing can score high, and lightly edited AI text can score low. Do not use it alone to accuse anyone.
What is an AI content checker?
An AI content checker estimates how much of a piece of writing reads like it was produced by an AI tool such as ChatGPT. It looks for patterns that are common in AI text: generic wording, very even sentence rhythm, stock phrases and a polished but impersonal tone. This free tool gives you an AI-written and human-written percentage and highlights the sentences that look most AI-like.
What the tool looks for
- Generic wording: template-like or marketing-style sentences that could describe anything.
- Even rhythm: balanced sentence lengths, parallel structures and lists of three.
- Stock AI phrases: words such as "delve", "leverage", "seamless" and "tailored".
- Missing personal voice: no first-hand experience, opinions or specific details.
- Over-polished tone: text that is perfectly smooth with no quirks.
How to use it
- Copy the text you want to check. You need at least 50 words.
- Paste it into the box above and click Check.
- Read the AI and human percentages and the verdict.
- Review the highlighted sentences, rewrite them in your own words, and check again.
How to read the result
A score of 60% or more is labelled likely AI-written, 35% to 59% is mixed, and below 35% is likely human-written. Treat the result as a signal, not proof. Formal or heavily edited human writing can score high, and lightly edited AI text can score low.
Frequently asked questions
Is this AI content checker free?
Yes. It is free and needs no login.
Is my text sent to a server?
Yes. Your text is sent to a free public AI service (Pollinations) for checking, so do not paste private or confidential content. If that service does not respond, the tool switches to a basic check that runs in your browser.
How accurate is an AI content detector?
The percentage is an AI model's estimate, not a guarantee. No detector is 100% accurate and results can be wrong both ways: formal or edited human writing can score high, and lightly edited AI text can score low. Do not use the result alone to accuse anyone.
What does the AI percentage mean?
The tool shows an AI-written percentage and a human-written percentage that add up to 100. A score of 60 or more is labelled likely AI-written, 35 to 59 is mixed, and below 35 is likely human-written.
How much text do I need to paste?
You need at least 50 words. Results are more reliable with 100 words or more, because very short text gives the tool little to measure.
