Four AI essay graders for teachers in 2026, and how to choose
Teachers who grade essays by hand spend hours on each class set. An AI essay grader cuts that time by scoring student writing against a rubric and drafting feedback. The tools differ in what they are built for, which learning management systems they connect to and how they are priced.
This list covers four AI essay graders for teachers. Every fact comes from the vendor's own website and was checked in October 2026. Prices and features change, so confirm on each site before you choose.
What to check in an AI essay grader
- Is grading student writing the main job or one feature among many?
- Does it score against a rubric you control?
- Which learning management systems does it connect to?
- Does it publish accuracy research and a data policy?

How to choose
If grading essays is most of your workload, pick a tool built for grading, with rubrics you control. If you want one platform for lesson planning and some grading, a broader suite fits. Whichever tool you pick, run a small class set you have already graded, compare its scores with your own and read what the vendor publishes about accuracy and student data. A free plan, such as EssayGrader's Basic plan with 100 essays a month, lets you run that test before paying.
