Compare AI grading tools
Use the scorecard to compare any AI grading tools on what they grade, how scores reach your LMS, and whether you can review every score. Set your priorities, fill in what each tool offers and see which one fits.
Rename the tools, set how much each row matters, then choose Yes, Partly, No or Not sure for each tool. Find the answers on each vendor’s own website.
What should you compare in an AI grading tool?
What each criterion means
| Criterion | Why it matters | What to ask |
|---|---|---|
| Kinds of work graded | Some tools are built for essays only | Does it grade math, short answers, quizzes and projects too? |
| Handwriting | Much student work is still on paper | Can I upload scans or phone photos, and how accurate is it? |
| Your rubric or answer key | Grades should match your standards | Does it score against my rubric and show reasons for each score? |
| Review before posting | You stay responsible for grades | Can I change every score and comment before students see them? |
| LMS sync | Retyping grades wastes the time you saved | Which LMSs does it connect to, and is sync included in my plan? |
| Student data privacy | You must protect student information | Is there a data processing agreement, and how is data stored and deleted? |
| Price and free plan | Costs add up across a team | How many submissions are free, and what is locked behind the paid plan? |
Questions to ask every vendor
- Which of my assignment types does it grade, and can I see an example of my kind of work graded?
- Can I see how a score was decided, and edit it before it reaches students or the gradebook?
- Does it work with the LMS my school uses, and does the plan I would use include that sync?
- What happens to student work after grading? Can I delete it, and is it used to train models?
- What is the total cost for me, and for the school if my colleagues join?

FAQ
Is an AI grading tool only for essays?
No. Some tools grade essays only, while others also grade math with work shown, handwritten tests, short answers, quizzes and projects. Check the kinds of work each tool supports before you choose.
Which AI graders work with Canvas and Google Classroom?
Check each vendor’s integrations page, because support varies. Common integrations include Google Classroom, Canvas, Google Forms, Microsoft Teams and Schoology. Also ask whether sync is included in the plan you would use, or only in school and district plans.
Is there a free AI grader for teachers?
Several tools have a free plan or trial. Compare how many submissions are free, whether LMS sync is included, and which features need a paid plan.
What should teachers compare before choosing an AI grader?
The kinds of work it grades, whether it reads handwriting, how scores reach your LMS, whether you can edit every score before students see it, student data privacy, and cost. The scorecard on this page turns those priorities into a match score.
Can AI grade handwritten work?
Some tools can read handwriting from scans or phone photos, but accuracy depends on the writing and the tool. Test it on a few of your own students’ papers and read the results closely.
How accurate is AI grading?
It varies by tool, subject and rubric. A clear rubric improves consistency, but AI scores should be reviewed, especially for high-stakes work. Treat the tool as a first pass that saves time, not a final grader.
How does the scorecard work?
Each row has an importance from Not needed to Essential. A Yes counts fully, Partly counts half, and No or Not sure counts zero. The match score is your points divided by the points possible for the rows you marked.
Does the scorecard store my choices?
No. Everything runs in your browser and nothing is saved, so print or copy the scorecard before you leave the page.
