For teachers

Grade with evidence, not suspicion

Review AI-writing signals with highlighted passages, score bands, and downloadable reports — so classroom conversations stay fair and documented.

Automatic flags feel unfair

Scores are probabilistic starting points. Reports show why a passage was flagged so you can judge in context.

Students deserve clarity

Plain-language explanations and appeal-friendly PDFs support honest writers without hiding the evidence.

Paper trails take time

Export branded reports in one click instead of stitching screenshots together for records.

Common questions

No — we focus on AI-writing signals, not source matching. Use reports alongside your existing integrity workflow.
