Academic integrity is under pressure as students increasingly submit AI-generated work. Teachers need reliable tools to identify AI-written essays, reports, and assignments without spending hours manually analyzing each submission. But most AI detectors are either expensive, inaccurate, or require institutional subscriptions.

Coda One's AI Detector for Teachers is completely free and unlimited. Paste any student submission to get a comprehensive analysis: an overall AI probability score, per-sentence breakdown with color-coded highlighting, and detailed pattern analysis showing exactly which writing characteristics triggered the detection. The multi-model approach (statistical, pattern, and ensemble) provides more reliable results than single-model detectors.

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 accurate is this for detecting student AI use?
Our multi-model detection provides reliable results for most academic content. The per-sentence analysis helps identify specific sections that show AI patterns. However, no detector is 100% accurate -- use results as one data point alongside your professional judgment about the student's writing ability and the assignment context.
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 unlimited student submissions?
Yes, completely free with no daily limits and no signup required. You can analyze as many student submissions as you need. No student data is stored or shared -- each analysis is processed and discarded immediately.
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 provides the most accurate results for English submissions. It may work with other Latin-script languages but with reduced accuracy. We recommend using it primarily for English-language student work.
