Reviewing 30 essays a week is tedious; reviewing them for AI use on top of grading is overwhelming. The detector gives you a fast first pass — a probability score and a sentence-level breakdown — so you can flag submissions that need closer attention without reading every essay through an AI lens.
Sentence-level scoring is the actionable signal
An overall score tells you something is off. A sentence-level breakdown tells you *where*. That's the difference between a vague concern you can't act on and a specific finding you can raise with a student.
False positives hurt students unnecessarily
The detector has a 2% false-positive rate in our 2026 testing — the lowest of the major tools. That matters because flagging legitimate human writing as AI is the most damaging mistake a detection tool can make.
The score is one signal, not a verdict
Detection is probabilistic. Use the score alongside your knowledge of the student, the writing context, and any other evidence. The tool exists to support your judgment, not replace it.

Teachers FAQs
Common questions about using the detector for teachers.
- How accurate is the detector for educational use?
- Our 2026 testing showed 96% true-positive and 2% false-positive rates across 200 documents — competitive with Originality.ai and stricter than GPTZero. No detector is infallible; treat the score as a strong signal, not a verdict.
- Can I review multiple submissions in batch?
- Free accounts handle one document at a time. Pro lifts the per-request limit and adds document history, which makes back-to-back reviewing faster.
- What about non-native English writers?
- Detection accuracy is somewhat reduced for non-native English writing across all major detectors — non-native rhythm patterns can resemble AI-shaped prose. Treat scores from non-native writers with extra context, and weight your judgment accordingly.
- Is student data shared or used for training?
- Submitted text is used only to return the detection result. We do not train models on user-submitted content. Review your plan and policy details for the latest retention terms.
