About Originality.ai's AI Detection

Originality.ai is widely used by content teams and publishers to detect AI-generated text. It analyzes writing patterns at the sentence level to identify machine-generated content.

GPTypo scans for the same signals — letting you identify and edit flagged sentences before your content goes through review.


What Originality.ai looks for

These are the types of signals that Originality.ai's classifier measures. GPTypo checks for the same patterns.

Sentence uniformity

AI text tends to produce sentences of similar length and rhythm. High variance is a signal of human writing.

Low perplexity

Predictable word choices with few surprises. Human writers are messier and less statistically smooth.

AI vocabulary

Overuse of phrases like "furthermore," "it is important to note," and "multifaceted" that appear far more often in AI output.

Structural repetition

Repeated paragraph openers, parallel sentence structures, and formulaic transitions between ideas.

Missing texture

Human writing has contractions, hedging, asides, and first-person markers. AI text tends to be uniformly polished.

Document coherence

AI text often has a narrow vocabulary range and smooth sentence-to-sentence flow that reads as artificially consistent.
