Rubric AI is a grading tool built for teachers, not students. You upload a rubric, paste in a student’s essay, and it drafts scores and rubric-aligned feedback for you to review and edit before anything reaches the student. This guide covers how it works, what it costs, and what to check before you rely on it for real grading.

TL;DR: Rubric AI drafts essay scores and feedback based on a rubric you provide, and it’s explicitly built around teacher review rather than fully automated grading. Pricing starts at $9 one-time for 5 essay grades, with monthly and annual plans for higher volume. Note that a few similarly named domains exist in this space; confirm you’re on rubricai.app before you sign up or pay anything.

What Is Rubric AI?

Rubric AI lets a teacher upload a grading rubric, paste in a student’s essay, and get back an editable score and written feedback that follows that specific rubric. The core idea is teacher control: the AI drafts the comments and score, but the teacher reviews and edits everything before it goes to the student. It’s positioned as a time-saver for grading load, not a replacement for a teacher’s judgment.

Key Features

Rubric-based grading: upload your own rubric and get feedback that follows its specific criteria, not a generic essay checklist.
Editable AI feedback: every comment and score can be reviewed and changed before a student sees it.
Revision suggestions: the tool also generates suggested next steps for the student’s revision.
Specialized graders: beyond general essays, it offers tools for AP essays, contract review, business proposals, and grant applications.

Pricing

Rubric AI’s published plans on rubricai.app are a $9 one-time Starter option for 5 essay grades, a Monthly plan at $19 for 150 grades, and an Annual plan billed at $12 a month for 1,800 grades a year, a savings of about 35% over monthly. A custom-priced School plan is available for institutions and programs grading at larger scale. Since pricing tiers can change, confirm the current numbers on the pricing page before you commit to an annual plan.

A Note on Similar Domain Names

Searching for Rubric AI turns up a few different domains using close variations of the name. We researched rubricai.app specifically, since it had the clearest product description and pricing page. If you land on a different “Rubric AI” site while searching, double-check it’s the same product and company before entering payment details, since grading tools in this niche aren’t all run by the same team.

Frequently Asked Questions

Is Rubric AI free?

There’s no free tier listed. The lowest-cost option is a $9 one-time Starter plan covering 5 essay grades.

Does Rubric AI grade essays automatically without a teacher?

No. It drafts a score and feedback based on your rubric, but it’s built around a teacher reviewing and editing that output before a student ever sees it.

Can Rubric AI be used for things other than essays?

Yes. Beyond general and AP essay grading, it also offers rubric-based tools for contract review, business proposals, and grant applications.

Is my rubric data private?

Check the current privacy policy on rubricai.app directly before uploading student work, since specific data-handling terms can change and weren’t detailed on the pricing page we reviewed.

Bottom Line

Rubric AI is built to save teachers time on grading, not to remove them from the process. The teacher-review step is the main safeguard here, and it’s a real one, since the AI never sends feedback to a student directly. If you’re grading at real volume, the annual plan is the better value, but start with the $9 Starter tier to see if the feedback quality matches how you actually grade.
