ChatGPT Detector Online — Free Accurate AI Content & Plagiarism Scanner
With millions of essays, cover letters, and web articles generated using OpenAI's ChatGPT (including GPT-4o and o1 models), verifying whether text was written by a human or generated by an algorithm has become an everyday requirement.
How to Tell If Text Was Written by ChatGPT
ChatGPT has noticeable stylistic hallmarks that human readers and machine learning models can readily identify:
- Overuse of Symmetrical Transition Words: Frequent use of "Moreover", "Furthermore", "In conclusion", and "It is worth noting".
- The "Balanced Compromise" Syndrome: ChatGPT habitually provides balanced, neutral viewpoints with qualifiers like "On the one hand... on the other hand".
- Robotic Sentence Uniformity: Almost every sentence contains between 15 and 22 words, producing a flat, metronomic cadence.
