Rubric-based AI essay grading for teachers
Reviewed by the the30top research team · Last reviewed 2026-10-27
Overview
CoGrader is an AI grader for essays and written work that scores against a rubric, writes personalized feedback and flags originality concerns. It integrates with Google Classroom, Canvas, Schoology, Brightspace, Microsoft Teams and Blackboard, and the site says teachers review and sign off before anything reaches students. The Starter plan is free forever with 150 free essays a month, but paid plan prices are not published and the product is aimed at US teachers.
Our verdict
A solid grading assistant with a real free tier and a human-in-the-loop design. It saves teacher time but does not tutor students directly.
Best for
Teachers who grade a lot of written work and want rubric-based feedback drafts.
Avoid if
You want a student-facing tutor rather than a grading assistant.
Pros
- Free forever starter plan
- Teacher review before grades are released
- Wide LMS integration list
Cons
- Paid prices not published
- US teacher focus
- SOC 2 Type 1, not Type 2
