I paraphrased my content and tried the AI Detector, but it was still flagged as AI. Why?

QuillBot’s Paraphraser is built to enhance clarity, tone, and style—not to bypass AI detection systems. While it may make your writing sound more natural or polished, it’s not designed to alter text in a way that avoids detection.

Additionally, AI detection tools are not 100% accurate. It’s possible for paraphrased or even human-written content to be or even human-written content to be flagged as AI generated as AI detection models can give varied results at times.

We'd love to improve! If you're comfortable sharing the flagged text, our Research team can use it to enhance the accuracy of our tools. Please reach out to Customer Support if you’d like to help.
