The range of perplexity is unknown, although values closer to 0 are highly likely to be artificially generated, while values closer to 100 are more likely to be human-written.

Similarly, for machine-generated content, perplexity is uniformly distributed and consistently low. Because humans naturally include more variation in their writing, patterns are less likely to predict it. This is how the content is detected through burstiness.

  • Displays the sentence with higher perplexity
  • API is freely available to integrate it into any system
