CoGrader: the AI copilot for teachers.

You can think of CoGrader as your teaching assistant, who streamlines grading by drafting initial feedback and grade suggestions, saving you time and hassle, and providing top notch feedback for the kids. You can use standardized rubrics and customize criteria, ensuring that your grading process is fair and consistent. Plus, you can detect if your student used ChatGPT to answer the assignment.

CoGrader considers the rubric and your grading instructions to automatically grade and suggest feedback, using AI. Currently CoGrader integrates with Google Classroom and will soon integrate with other LMS. If you don't use Google Classroom, let your LMS provider know that you are interested, so they speed up the process.

Try it out! We have designed CoGrader to be user-friendly and intuitive. We offer training and support to help you get started. Let us know if you need any help.

Privacy matters to us and we're committed to protecting student privacy. We are FERPA-compliant. We use student names to match assignments with the right students, but we quickly change them into a code that keeps the information private, and we get rid of the original names. We don't keep any other personal information about the students. The only thing we do keep is the text of the students' answers to assignments, because we need it for our grading service. This information is kept safe using Google’s secure system, known as OAuth2, which follows all the rules to make sure the information stays private. For a complete understanding of our commitment to privacy and the measures we take to ensure it, we encourage you to read our detailed privacy policy.

CoGrader finally allows educators to provide specific and timely feedback. In addition, it saves time and hassle, ensures consistency and accuracy in grading, reduces biases, and promotes academic integrity.

Soon, we'll indicate whether students have used ChatGPT or other AI systems for assignments, but achieving 100% accurate detection is not possible due to the complexity of human and AI-generated writing. Claims to the contrary are misinformation, as they overlook the nuanced nature of modern technology.

CoGrader uses cutting-edge generative AI algorithms that have undergone rigorous testing and human validation to ensure accuracy and consistency. In comparisons to manual grading, CoGrader typically shows only a small difference of up to ~5% in grades, often less than the variance between human graders. Some teachers have noted that this variance can be influenced by personal bias or the workload of grading. While CoGrader works hard to minimize errors and offer reliable results, it is always a good practice to review and validate the grades (and feedback) before submitting them.

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.

Just try it out! We'll guide you along the way. If you have any questions, we're here to help. Once you're in, you'll experience saving countless hours and procrastination, and make grading efficient, fair, and helpful.
