AI Content Detector
Last updated: May 26, 2026AICheck if text reads as AI.
The AI Content Detector estimates how likely a piece of text was AI-generated and shows a 0–100 score with the signals behind it — instantly, free, with no sign-up or word cap. Treat it as a guide, not a verdict: AI detection is probabilistic and no detector is 100% accurate, so weigh the score alongside your own judgment rather than treating it as proof.
How to use AI Content Detector

Check if text was written by ChatGPT
Paste a passage you suspect came from ChatGPT, Claude or Gemini and get a likelihood score with the patterns behind it. It is a fast first read on whether writing looks machine-generated — not a definitive answer.
Get a quick read on submitted work
Editors and educators can use the score as one early signal among many. It should never be the sole basis for an accusation — pair it with context like drafts, version history and a conversation, since detectors can misjudge honest writing.
Sanity-check your own writing
Writers can check whether a draft reads "too AI". If the score is high and you want it to sound more natural, run it through the AI Humanizer, then re-read it yourself.
Understand the score and its limits
The estimate reflects patterns like low perplexity and uniform sentence rhythm that are common in AI text. Short passages, heavily edited text and writing that mixes human and AI input are the least reliable to judge — so read the number as a probability, not a fact.
AI Content Detector — frequently asked questions
How accurate is the AI content detector?
It estimates the likelihood that text is AI-generated and shows the signals behind the score, but no detector is 100% accurate. Treat the result as a helpful guide rather than definitive proof, and use your own judgment.
How do AI detectors work?
They look for statistical patterns that are more common in machine writing than human writing — such as low "perplexity" (how predictable the next word is) and low "burstiness" (how much sentence length and rhythm vary). Those are signals, not certainties.
Can the detector be wrong or give false positives?
Yes. Genuine human writing — especially from non-native English speakers or in a plain, formal style — can be misjudged as AI, and edited AI text can read as human. Never use the score alone to accuse someone of using AI.
What does the score mean?
The score reflects how strongly the text shows patterns common to AI writing. A higher score means it more closely resembles AI-generated content, while a lower score suggests it reads more like human writing.
Is it free and private?
Yes, it is free with no login or word cap. Your input is sent securely to Cloudflare's edge AI and is not stored.
