AI Text Detection API

Know if text was written by humans or AI. Our detection API helps you spot AI-generated content from ChatGPT, Gemini, Claude, and other AI models with reliable accuracy.

Detect AI-generated Content

Generative AI tools have completely changed how we create content. They’re amazing tools, but sometimes you really need to know that content is authentic:

  • Academic Honesty: We want to empower students to develop their own writing skills and critical thinking
  • Content Quality: Your readers trust that content comes from real human experience and expertise, while content generated by LLMs often contains inaccuracies or lacks depth
  • Brand Trust: Your audience expects you to be upfront about how your content is created
  • Legal Requirements: Some fields actually require proof that humans wrote the content

AI-generated text can look exactly like something a person wrote. Our detection API helps you tell the difference, so you can keep things authentic and trustworthy in a world where AI is everywhere.

Spot AI Content Reliably

Our detector has been tested by independent researchers and catches AI-generated text with excellent accuracy and very few false alarms.

Since the inception of LLMs we have been rigorously testing and improving our detection tools. The result is a powerful and flexible API which can be used with confidence. Our AI detection gives you all the details you need to make confident decisions about content authenticity.

AI Detection Logic

Our AI detection has been independently tested, both internally as well as by 3rd party researchers, and shown to have exceptional accuracy in identifying AI-generated text, with very low false positive rates. In addition, we are constantly updating our detection algorithms making sure we are up-to-date with the latest generative AI models.
