How this AI detector works (and where it fails)
This detector reads surface signals, not provenance: uniform sentence rhythm, hedging patterns, formulaic transitions, generic phrasing where a human would be specific. Heavy AI editing passes blur those signals - which is the point of editing.
No detector can know where text came from. Scores are estimates, and short texts are unreliable - a 40-word paragraph barely has enough surface to read. That's why we show the individual observations: read them, agree or disagree, and treat the number as a hint rather than a verdict.
The useful move after detection isn't hiding anything - it's editing until the text is genuinely good. Run the AI humanizer next, then a human pass, then see whether answer engines cite you: that's what Sonarvue tracks.
