Grading Accuracy

Grades like an experienced AP reader

We publish how the grader is measured — side-by-side comparisons against experienced AP teachers, per rubric row, updated with every model release.

Benchmarked against AP teachers — less than 4% variance from human grading across 1,000+ essays, including AP Lang FRQs.

Scored per rubric row — thesis, evidence & commentary, sophistication each reported separately, not one blended number.

Re-tested continuously — every model update re-runs the full benchmark on College Board rubrics before release.

Fair for every student — bias-checked across writing styles, grade levels and English-learner status.

What AP teachers are saying

Dana T. Bedden

Superintendent of Schools, Centennial School District, Pennsylvania

This is our first year using Essay Grader, and we have been SO happy with every aspect of this program. Many of our teachers were very skeptical about using AI to grade essays. Now that we are all using it, they absolutely LOVE it! The true beauty of this product is the immediate feedback you can give your students when they complete an essay.

EssayGrader.AI has transformed my classroom. My students can write essays, receive feedback overnight, and revise their work based on detailed and helpful suggestions. The feedback is strictly aligned with the AP rubric (manually uploaded), breaking down scores by each category and offering specific advice on how to improve.

Is EssayGrader free?

EssayGrader offers a free plan that lets you get started without a credit card. Paid plans unlock higher volumes, bulk grading, advanced rubrics, and Google Classroom integration.

Does EssayGrader detect AI-written content?

Yes. EssayGrader includes an AI Content Detector as part of its grading workflow, so teachers can detect and grade in one platform without switching tools.

Can I use EssayGrader and GPTZero together?

Yes, many teachers do. They use GPTZero to flag academic integrity concerns and EssayGrader for the actual grading workflow. That said, EssayGrader includes its own built-in AI Content Detector, so you may not need both.

Does GPTZero grade essays?

No. GPTZero detects whether student writing was generated by AI. It does not apply rubrics, assign scores, or generate feedback. For grading, you would need a separate tool like EssayGrader.

Is EssayGrader better than GPTZero for teachers?

Yes — if your goal is grading essays. EssayGrader is purpose-built for rubric-based scoring, structured written feedback, and classroom management. GPTZero focuses exclusively on AI content detection and does not provide grades or feedback.

EssayGrader is blocked on my school network. How do I enable it?

Ask your IT team to whitelist the following domains:

essaygrader.ai
app.essaygrader.ai

If they need any help, feel free to contact us by sending a quick note to support@essaygrader.ai and we’ll be happy to assist.

Does EssayGrader integrate with Schoology?

We are working on a Schoology integration and we should release that by September 2025.

Faster Grading. Better Feedback. More 5s in July.
