Probability based on n-gram distribution and structural variance.

Expert Insight: AI writing often lacks "Burstiness"—the natural variation in sentence length that humans possess.

What This Tool Does

As AI tools like ChatGPT and Gemini become more popular, it's getting harder to tell what's written by a human and what's generated by a machine. Whether you're an editor checking a guest post, a teacher reviewing an essay, or a business owner verifying a freelancer's work, you need to know the origin of your content.

Our AI Content Detector analyzes the 'invisible fingerprints' of AI writing. It looks for 'Burstiness' (variance in sentence structure) and 'Perplexity' (predictability of words). Human writing is naturally messy and varied, while AI writing is often too perfect and consistent. Our tool gives you a probability score so you can make an informed decision about the integrity of your text.

How to use

  • 1Step 1: Paste at least 50 words of text into the scanner.
  • 2Step 2: Click 'Scan for AI Patterns'.
  • 3Step 3: View the 'AI Likelihood' score and the verdict (e.g., Highly Likely AI).
  • 4Step 4: Review the 'Detection Details' to see how the logic reached its conclusion.
  • 5Step 5: Use this data to start a conversation about originality or to prompt a rewrite.

Example Scenarios

Use Case 1:Content Editing: Verifying that your guest writers aren't just 'phoning it in' with AI-generated drafts.

Use Case 2:Academic Integrity: Helping educators identify work that doesn't match a student's usual voice.

Use Case 3:SEO Compliance: Ensuring your site doesn't have too much low-quality AI content that might be penalized by Google.

Use Case 4:Self-Check: Making sure your AI-assisted drafts have enough 'human' variance before you publish them.

Why It's Useful

Advanced Analysis: Uses statistical patterns that are much harder to 'trick' than simple keyword checks.
Fast Verdict: Get a probabilistic result in seconds, allowing you to filter through content quickly.
Transparency: We show you the logic (variance and diversity) behind the score.
Privacy First: Your sensitive documents are analyzed locally. We don't use your text to train our own models.

Tips for Best Results

Let's be honest: no detector is 100% perfect. Use this as a 'smoke detector' to find things that need a closer look, not as final proof.
Most people get this wrong: they think 'robotic' writing is always AI. Some humans just have a very formal style!
The more text you provide, the more accurate the result. A 500-word sample is much better than a 50-word one.
If you suspect AI but the score is low, look for 'hallucinations'—facts that sound true but are actually made up.

Frequently Asked Questions

How accurate is AI detection?

Detection is probabilistic. It looks for patterns common in AI writing. While highly effective, it can occasionally misidentify human writing as AI or vice versa.

Does it work with GPT-4 and Gemini?

Yes, our algorithm is designed to detect patterns from all major large language models, including the latest versions of GPT, Gemini, and Claude.

Is my text saved during detection?

No. All analysis happens entirely in your browser. We do not store or use your text for any purpose.
