⚠️ The Truth About “False Positives”
No AI detector is 100% perfect. A “false positive” happens when a tool incorrectly flags human writing as AI-generated. This creates panic for students.
How we minimize this:
- We tuned our threshold to favor “Human” when in doubt. We’d rather miss an AI essay than accuse an innocent student.
- We recommend using our tool as a “probability indicator”, not a final judge.
If you get a high AI score but wrote it yourself:
Try rewriting sentences with more variety (burstiness) or adding personal anecdotes. Highly formulaic or repetitive writing often triggers detectors.
