Does Turnitin Detect AI? How It Works & How to Pass

Does Turnitin Detect AI?

Yes. Turnitin’s AI detection, launched in 2023, analyzes submissions for patterns typical of AI writing—low perplexity, uniform burstiness, and formal transitions. Unedited ChatGPT, Claude, or similar output is often flagged.

How Turnitin Detects AI

Turnitin uses machine learning trained on large datasets of human and AI text. It measures:

• Perplexity: How predictable each next word is. AI tends to be more predictable.
• Burstiness: Variation in sentence length. AI is often more uniform than human writing.
• Transitions and phrasing: Overuse of formal connectors (“Furthermore,” “Moreover”) and similar markers.

If your text matches “AI-like” patterns, Turnitin shows a percentage of content likely AI-generated. Humanized or heavily edited AI often scores lower because those patterns change.

How RealTouch AI Helps You Pass Turnitin

RealTouch AI is an AI humanizer built to change the same patterns Turnitin uses:

• Raises effective perplexity so text looks less “predictable”
• Adds natural burstiness (short and long sentences)
• Reduces robotic transitions and phrasing
• Keeps your meaning and academic tone

Many users report high pass rates when they humanize with RealTouch AI and then submit. Results depend on your original text and Turnitin’s current model—always use in line with your school’s rules.

Frequently Asked Questions

Does Turnitin detect AI?

Yes. Turnitin’s AI detection flags unedited AI content using perplexity, burstiness, and phrasing. Humanized or edited AI text can pass.

Does Turnitin detect ChatGPT?

Yes. Unedited ChatGPT output is often flagged. Humanized ChatGPT text often passes when it matches human statistical patterns.

How does Turnitin detect AI?

Turnitin uses machine learning on patterns like low perplexity, uniform burstiness, and formal transitions to classify text as AI or human.

Can humanized AI pass Turnitin?

Yes. Tools like RealTouch AI change those patterns so text scores more human. Many users report high pass rates when used correctly.
