Is using AI Grader free?

You can predict your grade and get three pieces of personalized feedback on your writing for free once per day. For unlimited grade estimates and detailed feedback on your entire paper, upgrade to Grammarly Pro.

How accurate is the AI Grader grade estimate?

The AI Grader agent is designed to help you align your writing with the assignment and grading rubric. It estimates your grade based on the information you provide, but it should not be taken as your actual grade.

Can AI Grader check for plagiarism?

No, AI Grader doesn’t check for plagiarism. Use our Plagiarism Checker agent and Citation Finder agent to make sure your work is original and thoroughly cited.

Will my school or professor know I used AI Grader?

AI Grader is designed for students to review and refine their assignments before submission. There is no instructor-facing component to it. Keep in mind, however, that AI generates the rewrite suggestions, so if you use them, your work could be flagged for AI use. We always recommend checking with your school’s AI policy before using AI features in any product. And when in doubt, you can use Grammarly’s AI Detector agent to check your work.

What are AI agents, and what do they do?

AI agents are smart digital helpers that take action for you, like providing expert feedback, predicting grades and reader reactions, or finding sources. Unlike the typical tools you’re used to, AI agents use your context to offer more useful writing support. You can try Grammarly’s agents anytime at app.grammarly.com, with more ways to access them coming soon!
