It helps you assess whether a piece of text was likely generated by AI, so you can make faster, higher-confidence decisions before publishing or submitting content.

Core Features & Use Cases

  • AI Authorship Scoring: Computes an overall 0–100 likelihood score plus multiple supporting metrics to interpret the result.
  • Granular Readability & Pattern Signals: Provides perplexity, burstiness, readability, and n-gram statistics to understand why the text is flagged.
  • Use Case: Before posting or submitting an article, essay, or report, you can run it through the skill to identify mixed or highly AI-likely drafts.

Quick Start

Run /detect-ai on the text you plan to submit or publish, and review the score.overall and verdict to decide whether the content should be humanized.

FAQPage Schema
How do I detect AI writing in an essay before submission?

To detect AI writing, submit your text to calculate an overall 0–100 authorship likelihood score and review the verdict to determine if the draft is AI-generated before submission.

What readability metrics help identify AI-generated text?

Readability metrics like perplexity, burstiness, readability scores, and n-gram statistics are analyzed to provide granular linguistic signals that explain why text is flagged as AI-generated.

Can I check article authorship likelihood for content moderation?

Yes, you can check article authorship likelihood for content moderation by generating a 0–100 score and linguistic metric breakdowns to validate written materials before publication.

What is the best way to review text perplexity before publishing?

The best way to review text perplexity is to analyze the text to extract supporting linguistic metrics, including perplexity and burstiness, to understand pattern signals prior to publishing.

Do I need an API key to run an AI authorship check?

Yes, you need an Authorization bearer token to make a POST request to the HumanizerAI API endpoint, which returns the overall score, wordCount, verdict, and metric breakdowns.

What should I do if my content receives a high AI likelihood score?

If your content receives a high AI likelihood score, the skill exposes supporting linguistic metrics so you can decide whether the flagged draft should be humanized before finalizing.
