Getting Started

How to Use the AI Detector

Three simple steps to verify the authenticity of any document.

Why It Matters

Benefits of AI Detection in Academia

Uphold Academic Integrity

Ensure assignments, assessments, and research submissions are genuinely student-authored, protecting the value of academic credentials.

Enable Fair and Consistent Assessment

Create fair, consistent evaluations by holding every student to the same standard of original work.

Promote Meaningful Learning

Encourage critical thinking and original writing by discouraging over-reliance on AI-generated content.

Common questions

How accurate are AI detectors for student work?
Detection accuracy depends on the model version, text length, language, genre, and how much the text was edited, so no single percentage describes every case. AI Sentinels returns an overall pattern score plus paragraph-level indicators, and treats the result as a review signal rather than proof. An educator reviews the evidence before any academic decision, which is why the report shows which passages carry the strongest indicators.
Can teachers check essays for AI writing for free?
Yes. The free tier never expires and includes 3 scans in total, not per month, with up to 10,000 words per scan, and no credit card is required. Paid plans raise the monthly word allowance and add priority processing, and the same allowance is shared with auto-marking. Institutions can request a scoped pilot when they need higher volume or LMS integration.
What does an AI detection score actually mean?
The score summarises how closely the writing matches statistical patterns common in AI-generated text. It is a review signal, not a calibrated probability or a verdict, and a high score is a prompt to look closer rather than a finding of misconduct. Paragraph-level indicators show where those patterns concentrate so a reviewer can compare the passage with the student’s previous work and draft history.
Does the detector work on languages other than English?
Detection quality varies by language, because pattern models are trained unevenly across languages and shorter or translated passages carry weaker signals. Treat non-English results as a weaker indicator and rely more on the paragraph-level evidence and the student conversation.
