Why AI Detectors Flag Your Content?
AI Detectors Flag Your Content Because AI's Write in a Pattern!
Predictable Patterns
AI content is easy to spot because it has a pattern. It is the same type of pattern every time.
Similar Structure
Sentences are very close to each other in how they are laid out.
Straightforward Words
The words are often very straight forward. They sound like someone talking in a formal way.
Pattern Detection
That pattern is what all these detectors look for. They do not look for if the content is true or not.
The Problem: They look for the way the content was made with a machine. Even good content written by a machine can be flagged.
