Real scenarios
What teachers actually run through AI Checker.
Lab report with mixed authorship — 60% score, sentence-level shows the conclusion section is the AI portion
Admissions essay coming back at 18% — likely human-written with light AI polish
Why this fits
The teachers use case, in detail.
Teachers are the largest user group for AI detection tools, and the workflow demands more nuance than other use cases. A high AI score is not, by itself, evidence of academic dishonesty — it's a signal to look more carefully. AI Checker's sentence-level breakdown is specifically designed for the teacher workflow: it lets you point to specific passages in a follow-up conversation rather than presenting the student with a single percentage. Best practices: pair the score with classroom context (Did the student turn in earlier work in their voice? Did they show drafts? Does the topic match their stated interests?), avoid using AI scores as the sole basis for any disciplinary action, and treat any score below 80% as ambiguous — the false positive rate on real human writing is approximately 1-2% even for our system. Teacher accounts on AI Checker include batch submission, gradebook export, and a privacy-first mode that doesn't log student text.
