AI Detectors vs. Plagiarism Checkers
AI detectors and plagiarism checkers are both used to verify the originality and authenticity of a text, but they differ in terms of how they work and what they’re looking for.
AI Detector or ChatGPT Detector
AI detectors try to find text that looks like it was generated by an AI writing tool, like ChatGPT. They do this by measuring specific characteristics of the text like sentence structure and length, word choice, and predictability — not by comparing it to a database of content.
Plagiarism Checker
Plagiarism checkers try to find text that is copied from a different source. They do this by comparing the text to a large database of web pages, news articles, journals, and so on, and detecting similarities — not by measuring specific characteristics of the text.
Scribbr & academic integrity
Scribbr is committed to protecting academic integrity. Our tools, like the AI Detector, Plagiarism Checker , and Citation Generator are designed to help students produce quality academic papers and prevent academic misconduct.
We make every effort to prevent our software from being used for fraudulent or manipulative purposes.
Your questions, answered
Scribbr’s AI Detector can confidently detect most English texts generated by popular tools like ChatGPT, Gemini, and Copilot.
Our free AI Detector can detect texts written using GPT2, GPT3, and GPT3.5 with average accuracy, while our Premium AI Detector has high accuracy and the ability to detect GPT4.
Our AI Detector is carefully trained to detect most texts generated by popular tools like ChatGPT and Bard. These texts often contain certain phrases, patterns, or awkward wording that indicate they were not created by a human. However, no AI model on the market can guarantee 100% accuracy, including ours. To get the best results, we recommend scanning longer pieces of text rather than individual sentences or paragraphs.
Our research into the best AI detectors indicates that no tool can provide complete accuracy; the highest accuracy we found was 84% in a premium tool or 68% in the best free tool.
The AI score is a percentage between 0% and 100%, indicating how much of the text contains content likely written or refined using AI tools.
No—Scribbr’s AI Detector will only give you a percentage between 0% and 100% that indicates the likelihood that your text contains contains AI-generated, AI-refined, or human-written content.
No—our AI content checker can only identify AI-generated, AI-refined, and human-written content. Our Plagiarism Checker can help prevent unintentional plagiarism in your writing.
Yes—our AI Detector can currently analyze text in English, Spanish, German, and French
