Burstiness
A measure of variation in sentence length and complexity within a text. Human writing naturally exhibits high burstiness — mixing short, punchy sentences with longer, complex ones. AI-generated text tends to be more uniform, which detectors use as a signal.
Understanding Burstiness
A measure of variation in sentence length and complexity within a text. Human writing naturally exhibits high burstiness — mixing short, punchy sentences with longer, complex ones. AI-generated text tends to be more uniform, which detectors use as a signal. This concept is central to understanding how AI-generated text differs from human writing and how tools like UnAIText help bridge that gap.
Why Burstiness Matters
Understanding burstiness is essential for anyone working with AI-generated content. Whether you're a student, content creator, or professional writer, knowing how this concept works helps you produce better, more natural content.

AI Detection
The process of analyzing text to determine whether it was generated by an artificial intelligence model such as ChatGPT, Gemini, or Claude. AI detectors use statistical patterns, perplexity scores, and machine learning classifiers to distinguish human writing from AI-generated content.
Perplexity Score
A statistical measure of how predictable a text is. AI-generated text tends to have low perplexity (highly predictable word choices), while human writing typically shows higher perplexity with more unexpected word selections and creative expressions.
