Yes, many US schools now use AI detection tools like Turnitin's AI writing indicator.

These tools don't 'prove' AI use but provide a probability score based on writing patterns.

AI detectors analyze factors like 'perplexity' and 'burstiness'—how uniform or varied the sentence structure is.

Text written by AI often lacks a unique personal voice and specific, personal anecdotes.

Teachers also look for inconsistencies in style compared to your previous work.

Another clue is perfect grammar but a lack of deep, critical analysis.

Using AI to brainstorm and then writing in your own words is the safest and best approach.

Understand that these detection tools are new and can sometimes be inaccurate.

The focus should be on learning and developing your own skills, not trying to beat a detector.

The risk of getting caught and facing academic dishonesty charges is not worth it.
