Why Do AI Detectors Flag Your Writing?
AI tools write in predictable patterns, and detectors are trained to catch them.
Predictable Patterns
AI-generated text follows the same patterns over and over. Detectors are built to recognize this.
Repetitive Sentence Structure
AI tends to build every sentence the same way, with similar length and layout.
Overly Formal Wording
AI writing often sounds stiff and formal. It lacks the casual flow that real human writing has.
What Detectors Look For
AI detectors scan for these patterns, not whether the content is accurate. Even good writing can get flagged.
The Problem: AI detectors don't judge quality. They look for machine-generated patterns. That means even well-written AI content can get flagged.
