GPT Zero: Your Free ChatGPT Detector
ChatGPT is now part of everyday drafting in school, work, and publishing. A detector can help identify passages that deserve a second read, but it cannot settle who wrote them.
This checker looks at statistical patterns in a passage, including word predictability, sentence variation, and structure. Those signals can be helpful, but they are not a fingerprint and can change when a draft is edited.
Use the result to guide an editorial conversation, to review your own draft, or to decide where more context is needed. Do not use it alone to accuse a student, reject a writer, or make a hiring decision.
How ChatGPT Detection Technology Works
The checker compares several linguistic signals. One is how predictable the next word tends to be. Another is how much sentence length and structure vary across the passage. Neither signal is decisive by itself.
People and models can both write in many styles. A short sample, technical prose, a translation, or a heavily edited draft can create a misleading result. More complete passages give the checker more context, not certainty.
Why Detection Accuracy Matters
False positives can have real consequences in school and at work. That is why a score should begin a review, not end one. Look at the passage, compare it with prior work when appropriate, and give the writer a chance to explain the context.
ChatGPT Detection for Academic Integrity
Universities and schools worldwide are grappling with the impact of AI writing tools on academic honesty. Our free detection tool helps educators quickly assess student submissions, while students can use it to verify their own work reads authentically before turning it in.
Detection for Content Creators and SEO
Search engines increasingly evaluate content quality signals. While AI-generated content is not penalized outright, text that lacks the natural variation and depth of human writing may underperform. Our tool helps content teams audit their output and ensure it meets quality standards.
