Content | Multilingual | API Support


Originality AI provides tools to detect AI-generated text and ensure content integrity.

Its AI Content Checker is intended for publication on the internet or in print, such as web content, blog posts, books, and news, rather than for academia. It can identify text generated by ChatGPT, GPT-4, Claude, and others.

Who Can Use It:

  • Publishers.
  • Marketing/Content Agencies.
  • Professional Writers.

How It Works?

It uses sophisticated machine learning models trained on massive datasets of human and AI writing samples. By analyzing the patterns differentiating the two, these models can detect telltale signs of whether new text originated from a human or an AI.

Key Features:

  • Industry-leading low rates of false positives where human-written text is incorrectly flagged as AI-generated.
  • Users can employ a browser extension to record and visualize the human writing process, proving content originality.
  • Enterprise-grade controls, security, team management, and API access for large-scale content operations.

Limitations and Considerations:

  • Cost barriers to access advanced capabilities.

While not officially stated, the free version allows you to check texts up to around 20,000 characters.
