Short, citation-ready explanations for AI detection and writing-integrity questions.
What does burstiness mean in AI detection?
Burstiness describes variation in sentence length, rhythm, and structure across a passage. In AI detection, burstiness can be one signal because some generated text appears unusually even, but it should never be used alone to decide whether writing is human or AI-assisted.
Is low burstiness always a sign of AI-generated writing?
Low burstiness is not always a sign of AI-generated writing. Formal essays, business reports, legal documents, templates, translated text, and carefully edited prose can all have consistent sentence patterns, so reviewers need additional signals and writing context.
How should burstiness be interpreted in an AI detection report?
Burstiness should be interpreted as one explanatory signal inside a broader AI detection report. Reviewers should compare it with sentence-level evidence, document length, genre expectations, revision history, and other originality signals before drawing any conclusion about authorship.
FAQ

No. Formal writing, templates, and edited prose can also have low variation.
Does WriteGo only use burstiness?
No. It should be one signal among many in the report.
