How accurate is Scribbr’s AI detection software?

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.
