Method note

How AI writing detection works

Plain English first: the model looks for clusters of machine-like writing habits. Formal terms second: it combines lexical and rhythmic signals into a bounded risk score.

Signal families

  • Lexical reuse: repeated stock transitions and high-frequency assistant phrases.
  • Syntactic uniformity: similar sentence templates repeated across paragraphs.
  • Rhythm compression: narrow sentence-length variance and low burstiness.

What this score means

A higher score means stronger overlap with known AI-typical pattern clusters in the submitted text sample.

What this score does not mean

The score does not prove who wrote the text. It is not an authorship verdict and should not be used as standalone evidence for accusations.

Reliability discipline

Interpret scores with context, revision history, and known detector failure modes. For real-world examples, see Do AI Detectors Work? and the False Positive Hall of Fame.

Anti-bypass boundary

WROITER is designed for diagnostic literacy and writing quality, not for evasion or undetectable output claims.
