What is CoGrader?
CoGrader is an AI-powered, rubric-based grading and feedback platform specifically designed for written assignments like essays and open-ended tasks. It helps teachers provide quality feedback on essays in 80% less time while maintaining high educational standards. The tool combines advanced AI technology with educator expertise to streamline the grading process, allowing teachers to focus on what truly matters—helping students succeed through tailored instruction and individualized support.
Key features include: importing assignments directly from Google Classroom, Canvas, and Schoology; creating or uploading custom rubrics aligned with state standards (including Common Core, TEKS, Florida B.E.S.T., California Smarter Balanced, STAAR, NY Regents, and AP/IB rubrics); generating detailed, personalized feedback and justification reports for each student; reviewing and adjusting grades before finalizing; accessing class-level analytics to identify learning gaps; and detecting potential AI-generated content to uphold academic integrity. The platform grades each submission automatically in under 2 minutes and shortens feedback turnaround to 1-2 days instead of weeks.
CoGrader is designed for K-12 teachers, AP/IB exam scorers, higher education educators, school administrators, and district leaders who want to reduce grading workload without sacrificing feedback quality. It supports differentiated learning by tailoring feedback to each student's diverse needs, ensures equity through objective rubric-based grading that minimizes human bias, and can assess assignments in any language while the interface remains in English. The tool is used by over 1,000 schools nationwide and pledges to impact five million students.
Privacy and security are top priorities, with CoGrader being FERPA, COPPA, SOPIPA, and Ed Law 2D compliant, holding SOC 2 Type 1 attestation, and following the NIST 1.1 framework. Only de-identified student work and rubrics are shared with AI models, and student data is explicitly not used for training purposes.

How does CoGrader protect student privacy?
Privacy is CoGrader's top priority. They maintain strict data protection standards including SOC2 Type 1 Compliance, FERPA compliance, and adherence to the NIST 1.1 framework. The system uses OAuth2 authentication through Google's protected systems and collects minimal data, using only anonymized student identifiers to match assignments. Only anonymized names and submissions are stored, with all content securely stored and encrypted. Detailed information is available in their Privacy Policy, Terms of Use, AI Transparency Note, and Third-Party Cybersecurity Assessment.
Can CoGrader detect cheating?
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 due to the complexity of human and AI-generated writing, CoGrader helps teachers by flagging possible academic dishonesty to inform follow-up conversations with students and uphold the school's policy.
How reliable are CoGrader's grade suggestions?
CoGrader's grade suggestions offer strong reliability with lower variance than the usual variance between human graders. The AI system uses advanced algorithms and extensive testing to ensure consistent grading, but 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.
Who is responsible for final grades with CoGrader?
The teacher. CoGrader is designed to assist educators by streamlining the grading process with AI-driven suggestions, but 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 grades and feedback before finalizing results. The final grading decision always rests with the educator, and CoGrader expressly disclaims liability for errors or inconsistencies.
Can CoGrader grade assignments in multiple languages?
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.
Do you train models using student data?
No, CoGrader does not use student PII to train their AI models. Additionally, their 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. Only de-identified student work and rubrics are shared with AI language models, and those models cannot use student data for training purposes.
