Analysis Details

How this works: This tool uses statistical text analysis — measuring burstiness (sentence length variation), vocabulary richness, repetition patterns, and transition word frequency. AI text tends to have low burstiness, high repetition, and formulaic structure. Results are probabilistic, not definitive. A score above 70% suggests likely AI content; below 30% suggests likely human content.

Burstiness Analysis

Measures sentence length variation — AI text is typically uniform.

Vocabulary Richness

Type-token ratio reveals word diversity patterns.

Repetition Detection

Identifies repeated phrases and structural patterns.
