Academic integrity is under pressure as students increasingly submit AI-generated work. Teachers need practical tools to review AI-written essays, reports, and assignments without spending hours manually analyzing each submission. But many detectors are expensive, opaque, or aimed at institutional buyers rather than day-to-day classroom use.

Coda One's AI Detector for Teachers starts directly in the browser, so you can review a submission without waiting on account setup or institution-level onboarding. Paste any student submission to get an overall AI probability score, per-sentence breakdown with color-coded highlighting, and pattern analysis showing which writing characteristics influenced the result. The multi-model approach (statistical, pattern, and ensemble) is meant to give a broader view than a single-score detector.

The per-sentence analysis is particularly valuable for educators. Instead of a simple "AI or not" verdict, you can see which specific sentences show AI patterns and which appear genuinely human-written. This helps you have informed conversations with students about their work rather than making blanket accusations based on a single score.

Frequently Asked Questions

How should teachers read the results?
Use the detector as one signal, not a final verdict. The per-sentence analysis can help highlight sections that deserve a closer look, but you should still weigh the student's writing history, drafts, and assignment context before drawing conclusions.
Can students beat this detector with AI humanizers?
Humanized AI text is harder to detect, but our multi-model approach catches many humanization attempts. Look for inconsistencies: if some sentences score very differently from others, or if the writing quality varies significantly throughout, these can indicate partial humanization of AI text.
Is it free for student submissions?
Yes. The detector is free to use. The analysis flow starts in your browser, and student text is not uploaded to our servers during detection.
How should I use AI detection results with students?
Use detection results as a conversation starter, not as proof of cheating. If a submission scores high, discuss it with the student. Ask them to explain their writing process, provide drafts, or answer questions about their content. High AI scores are an indicator, not a conviction.
Can I check papers in languages other than English?
The detector is optimized for English text and is most useful on English submissions. It may work with other Latin-script languages, but results can be less consistent there.
