CoGrader's AI Detection feature (available on School/District subscriptions) helps identify potential AI-generated content. While no tool can guarantee 100% accuracy in AI detection, CoGrader helps teachers by flagging possible academic dishonesty to inform follow-up conversations with students and uphold the school’s policy.

CoGrader's grade suggestions offer strong reliability, with typical grade variations of up to 5% - lower than the usual variance between human graders. While the AI system uses advanced algorithms and extensive testing to ensure consistent grading, it's designed to assist rather than replace teacher judgment.

Educators maintain control by reviewing and adjusting both grades and feedback before finalizing them, combining AI efficiency with human expertise.

We only collect information necessary to provide and improve our grading and feedback services. This includes assignment details, student work submissions, and metadata such as timestamps and assignment identifiers. We do not collect sensitive personal information.

The teacher.

CoGrader is designed to assist educators by streamlining the grading process with AI-driven suggestions. However, the final feedback and grades remain the responsibility of the educator.

While CoGrader aims for accuracy and fairness, it should be used as an aid, not a replacement, for professional judgment. Educators should review and validate the grades and feedback before finalizing results.

The use of CoGrader constitutes acceptance of these terms, and we expressly disclaim any liability for errors or inconsistencies. The final grading decision always rests with the educator.

Yes, CoGrader can assess and provide feedback on assignments in any language, while the platform interface remains in English. The system can evaluate student work and generate detailed feedback in the same language as the submitted assignment, supporting multilingual education environments.

We maintain a minimal data collection approach, gathering only the essential information required to provide and improve our grading and feedback services. This includes assignment details, student work submissions, and basic metadata such as timestamps and assignment identifiers. To protect privacy, we specifically exclude sensitive personal information from our collection processes.

When processing assignments, we send only anonymized data to our AI language models. This includes the text of student submissions and necessary context from assignment prompts, ensuring effective assessment while maintaining privacy.

No, we do not use student PII to train our AI models. Additionally, our agreements with third-party AI providers explicitly prohibit using shared data for model training. This ensures student privacy and maintains clear boundaries between assessment and AI development.
