More clarity, less confusion
Paraphrasing and grammar checking tools are ethical uses of AI writing technology. They help millions of non-native English speakers and writers refine their text and express their ideas fluently.
But most AI detectors can’t tell the difference between text that’s been generated with AI and text that’s been refined using these tools. This leads to false positives and cultural bias.
So we built a better AI detector.
