An AI Detector for Teachers Who Need Answers, Not Just a Score
Paste a student essay or assignment and see exactly which sentences read as AI-generated — built for classrooms, not just compliance.
Generic plagiarism checkers were built for a world before ChatGPT — they compare text against a database of existing sources, which does nothing when a student's essay was never published anywhere. An AI content detector for teachers works differently: it analyzes how the text was likely produced, looking at word predictability, sentence rhythm, and structural patterns that large language models like GPT-5 and Claude leave behind, even in original, never-before-seen writing.
ContentScan gives educators a free way to run that check on individual essays or a full stack of submissions, without an LMS integration or a paid seat. You get a sentence-level breakdown instead of a single percentage, so you can see which specific parts of an essay triggered the flag and make an informed judgment call — because no detector, including this one, should be the final word on academic integrity.
Built for how teachers actually grade
Sentence-level evidence
See exactly which sentences read as AI-generated instead of trusting one opaque score for the whole essay.
No AI humanizer blind spot
Our classifier is trained to catch AI text that has been run through "humanizer" tools to dodge simpler detectors.
Free, no LMS required
Paste text directly — no Canvas, Moodle, or Google Classroom integration needed to get started.
Fair to ESL and formal writers
Style-metric-aware scoring reduces the false-flag risk that trips up non-native English speakers and highly formal writing.
