Built for fairness

More clarity,
less confusion.

Paraphrasers and grammar tools are ethical uses of AI. They help millions of non-native English speakers and writers refine their work.

But most AI detectors can't tell the difference between content generated by tools like ChatGPT and text that's been refined with assistive tools. That leads to false positives and cultural bias.

So we built a better AI detector.
