CoGrader
What is CoGrader?
CoGrader is an AI-powered grading and feedback platform for educators evaluating essays, quizzes, and other open-ended assignments. It uses teacher-selected or custom rubrics to generate suggested scores, comments, and writing feedback that educators can review before sharing. The platform supports K-12 teachers, schools, districts, and test-preparation programs with rubrics aligned to standards such as AP, STAAR, CAASPP, and other state assessments. CoGrader integrates with classroom workflows including Google Classroom, Canvas, Schoology, and manual uploads. Its main differentiator is combining automated rubric-based assessment with teacher approval, academic-integrity checks, class insights, and education-focused privacy controls.
How to use CoGrader?
1. Create a free CoGrader account and import student work from a supported classroom platform or upload files manually. 2. Select an existing standards-aligned rubric or create your own, then run the AI grading workflow. 3.
