AI detection just got a lot better: Announcing Checkfor.ai

NOTE: We've changed our name to Pangram Labs! See our blog post for more details.

Today, we are launching Checkfor.ai, a tool to detect AI-generated content with a simple copy and paste.

Our mission is to protect the digital world from low-quality AI-generated content that threatens authentic human voices. Our product allows content publishers, review platforms, educators, and creators to verify that their content was written by a real human being.

Why do we believe we can solve this challenging problem? We are a small team of experienced machine learning researchers and engineers who simply know how to bring working models into production environments. Our team has shipped real-world machine learning products at Google, Tesla Autopilot, and Nuro. We are obsessed with reliability and trust, and will not just stop when our test set accuracy hits 99%. Our goal is not just to be the best-in-class detector, but to be reliable enough for high stakes, real-world deployments that demand low false positive and false negative rates.

We’ve only been working on this problem for about a month, but have already made great progress. While our detector isn’t perfect, we believe it is already better than competitor detectors by a good margin, especially on creative writing and user-published online content. We’re looking forward to improving the performance of the tool and sharing some exciting results in the coming weeks.

Give it a shot at Checkfor.ai!
