Free AI essay grader.
Paste your essay and get a grade in about ten seconds: a score out of 100, marks for five criteria, what works, and the three fixes that will make the biggest difference, each pointing at your own sentences.
How it grades
Five criteria, the way markers read.
Most essay rubrics, from high school to postgraduate, come down to the same five questions. The grader scores each from 1 to 5, then gives an overall score out of 100 that reflects your level: a strong high school essay and a strong master's essay are held to different standards.
Thesis and focus
Is there a clear, arguable position that answers the prompt, and does every paragraph serve it? A 5 states the thesis early and keeps to it; a 2 drifts or never commits.
Structure and flow
Do paragraphs follow a logical order, each with one main point, linked by transitions? Strong essays move from claim to support to significance, then on to the next idea.
Evidence and support
Are claims backed by examples, data or sources, and are those sources cited? Sweeping statements ("everyone knows…") and uncited facts lose marks here.
Analysis
Does the essay explain why the evidence matters, deal with counterarguments, and reach conclusions the evidence supports? This is where good essays become strong ones.
Style and mechanics
Clear sentences, the right register for the level, and correct spelling, grammar and punctuation. Run-on sentences and slips like there/their are the usual culprits.
Scores
What your score means.
| 85–100 | Excellent | Ready to submit, with only polish left. |
|---|---|---|
| 75–84 | Strong | A good essay; one or two areas would lift it further. |
| 60–74 | Good | Competent; the fixes below are worth making before you submit. |
| 45–59 | Developing | The ideas are there, but structure or support needs work. |
| 0–44 | Weak | Rework the thesis and the paragraph plan first. |
Using the feedback
Turn the grade into a better essay.
- Start with the lowest criterion. A weak thesis or structure costs more marks than any typo.
- Work through the three fixes in order; each one quotes the passage, so you can find it fast.
- Fix the pattern, not just the sentence: if one claim lacks a source, check every claim like it.
- Proofread last, reading aloud, once the bigger changes are done.
- Grade it again. A rise in the weakest criterion tells you the change worked.
Limits
What the free grader doesn't do.
It gives one quick reading, so treat it as a second opinion rather than a final mark. It doesn't open the sources you cite, check for plagiarism, or predict AI-detection results, and it only knows your assignment if you paste the prompt or rubric. Your teacher's rubric and comments always come first.

FAQ
Essay grader questions.
Is the AI essay grader free?
Yes, with no account. You can grade up to 5 essays an hour and 10 a day, each up to 2,500 words. For longer essays, a rubric file and source checks, use AI Review inside EssayMate.
How accurate is the grade?
It's a careful estimate, not your teacher's mark. The grader is told to mark the way a fair marker at your level would, where most competent essays land between 60 and 80, and its feedback quotes your own sentences so you can judge it yourself. Pasting the assignment prompt or rubric makes it fairer.
Is my essay saved or shared?
It isn't saved to EssayMate or linked to you. It's sent to the AI model that grades it and the result comes straight back to your browser. Don't paste anything you're not allowed to share.
Does it check plagiarism or AI detection?
No. It grades the writing: thesis, structure, evidence, analysis and style. It doesn't compare your essay with other texts or predict what an AI detector would say.
Can it grade college application essays?
Yes. Choose "College application essay" as the type and paste the prompt. Personal statements are judged on focus, structure, specific detail and voice rather than on sources.
Does it check my sources?
It judges whether claims are supported and cited, but it doesn't open your sources. AI Review in EssayMate checks each reference and whether it supports what you cite it for.

Writing the essay too?
EssayMate finds real sources and cites them while it writes.
Give it the brief and it delivers a cited essay as a Word or PDF file, in APA, MLA, Chicago, Harvard or IEEE.
