Our analyzer evaluates thousands of linguistic signals to distinguish human-written text from AI-generated content. It examines:
- Repetitive phrase patterns — AI models often reuse similar word sequences; human writing tends to vary more
- Templated sentence structure — Exact or near-exact repeated sentences suggest AI generation
- Repeated sentence openings — AI output often reuses the same lead-in pattern across many sentences
- Lexical diversity — Human writers typically use a wider vocabulary range; AI output can be more constrained
- Sentence rhythm — AI tends toward uniform sentence lengths; human prose has more natural variation
- Generic phrasing markers — Overuse of boilerplate transitions and broad abstractions can signal generated text
