About Our AI Detector

The AI Detector by SEOAegis is designed to identify whether text was written by a human or generated by artificial intelligence. Unlike simple classifiers, it combines multiple linguistic signals—such as perplexity proxy, burstiness, repetition patterns, and style uniformity—to deliver a clear confidence score. This transparency helps content creators, educators, and businesses make informed decisions about the authenticity of text.

Why Use an AI Content Detector?

With the rapid rise of tools like ChatGPT and other large language models, it has become harder to distinguish human writing from machine-generated text. Our detector gives you a reliable way to spot AI-generated patterns, safeguard originality, and maintain trust with your audience. Whether you’re reviewing student essays, auditing SEO content, or checking guest posts, this tool provides evidence-based analysis rather than a black-box guess.

How the AI Detector Works

  1. Paste your text into the input box and select your preferred sensitivity (Normal, Strict, Lenient, or Strict+).
  2. Enable optional highlighting to see which sentences appear most suspicious.
  3. Click Analyze to generate a Human-like vs AI score, supported by transparent evidence and a detailed breakdown of signals.

Key Features

  • Clear Human vs AI scores presented as both percentages and visual meters.
  • Evidence list showing repetition, lexical diversity, and other markers.
  • Multiple sensitivity modes for stricter or more lenient detection.
  • Downloadable reports in JSON or CSV for record-keeping.

FAQs

Is the AI detection result guaranteed?

No AI detector can be 100% accurate. Our results are probabilistic and should be used as one factor in a broader editorial or academic review.

What languages are supported?

English provides the strongest signals in this version. Other languages may work, but accuracy can be lower depending on text length and structure.

How are credits used?

Each analysis consumes 1 credit for logged-in users. Guests can try 5 free checks per day before needing an account.

Who should use this AI detector?

It’s useful for teachers checking assignments, publishers auditing submissions, SEO professionals reviewing content quality, and businesses verifying originality in reports or proposals.

Can AI writing ever be completely undetectable?

Advanced rewriting tools may reduce AI signals, but no text is entirely undetectable. This is why our detector focuses on multiple features, giving you a higher chance of spotting AI-generated passages.
