The AI essay grader evaluates your document across six dimensions. It returns a letter grade, a score out of 100, and a full report in under 10 seconds.
Work through the Fix List
The Fix List ranks every issue by grade impact versus time to fix. The My Essay tab highlights problem sentences directly in your text. The Structure tab maps your argument from hook to conclusion. The Feedback tab explains each dimension score in full. Start at the top of the Fix List and work down before you revise.
What our AI essay grader evaluates
Our AI evaluates six key writing dimensions, providing scores, inline feedback, and prioritized improvements.
Thesis & Argument
Evaluates the clarity and strength of your thesis and how well your evidence supports it. Highlights vague claims, weak arguments, and unsupported positions.
Evidence & Support
Assesses whether your claims are backed by credible evidence, citations, or relevant examples. Flags unsupported statements that need stronger proof.
Structure & Flow
Analyzes essay organization, paragraph order, and transitions. Identifies logical gaps and suggests ways to improve the overall flow.
Citations & References
Reviews APA, MLA, Chicago, and Harvard citations for accuracy and consistency. Detects formatting errors, missing references, and citation issues.
Clarity & Style
Measures readability, academic tone, sentence variety, and word choice. Highlights wordy, repetitive, or informal language with clear revision suggestions.
AI Detection Risk
Estimates the likelihood that your writing may be flagged as AI-generated. Highlights high-risk passages so you can revise them before submission.

AI essay grader for every grade level
The grading criteria adjusts to your level. Select the correct level before grading.
Middle School
Evaluates clear topic sentences, basic paragraph structure, and a developed central idea. Scoring is calibrated to middle school marking standards. Vocabulary and sentence complexity are weighted at an age-appropriate level.
High School
Assess for a defensible thesis, organised argument, supporting evidence, and consistent academic tone. Select High School for any class from grade 9 through 12, including AP Lang and AP Lit assignments.
Undergraduate
Checks citation accuracy, argument depth, engagement with counterarguments, and quality of evidence. Citation accuracy and engagement with counterarguments carry the most weight at this level. This is where most students use the rubric upload feature.
Graduate & PhD
Reviews scholarly rigour, specificity of claims, quality of sources, and argument sophistication. Set Grading strictness to Strict to reflect demanding examiners. PhD-level scoring expects every major claim to be traceable to a peer-reviewed source.
Essay Types Our AI Essay Grader Supports
Select your document type before grading so the AI applies the right criteria.
Argumentative essays
The argumentative essay grader checks whether your position is clearly stated, whether you address counterarguments, and whether your evidence actually supports your claims rather than just illustrating them.
Analytical essays
Analytical grading looks at how well you interpret and break down a text, idea, or dataset, not just whether you describe it. Depth of analysis and use of textual evidence are weighted heavily.
Research papers
Research paper grading checks citation accuracy, source quality, argument coherence across a longer piece, and whether your introduction and conclusion properly frame your findings.
College application essays
Personal statement grading focuses on voice, specificity, narrative structure, and whether the essay answers the prompt. Generic language and clichéd openings are flagged as issues.
Grading with a custom rubric
Paste your professor's rubric into the advanced options and the AI grades against your specific criteria rather than generic academic standards. This is the most accurate way to predict your actual grade.
Tools to Use Alongside the AI Essay Grader
Use these tools alongside the AI essay grader to improve originality, clarity, grammar, and overall writing quality.
Frequently asked questions
An AI essay grader analyzes your essay against academic writing standards rather than checking grammar alone. It scores your thesis, structure, evidence, citations, readability, and writing quality before generating a detailed report with actionable feedback and an overall grade.
Yes. You can grade three documents without creating an account. No email address, no credit card, no sign-up required. The free report includes the letter grade, score out of 100, all six category scores, inline annotations, and the Fix List. A free account gives you five grader reports every month permanently. Paid plans start at $8.99 per month.
An essay grader returns a letter grade and scores your writing across argument, structure, evidence, and citations. An essay checker flags grammar mistakes, spelling errors, and punctuation issues. An essay grader will not fix a comma splice. A grammar checker will not tell you your thesis is too vague to argue. Run the grader first, then run a grammar check on the revised draft.
The grader has a 93% accuracy rate against human graders for objective criteria including citation format, argument structure, unsupported claims, and academic tone. For subjective criteria like originality or personal voice, treat the output as a strong directional signal. The more context you give such as grade level, document type, and rubric, the more accurate the result.
The AI detection risk rating shows as low, medium, or high on the free tier, and as a percentage on paid plans. It estimates how likely your document is to be flagged as AI-generated by tools like Turnitin, based on writing patterns including sentence uniformity and hedging language. A medium or high rating does not mean your document is AI-generated. The My Essay tab highlights the sentences most likely to trigger a flag. This rating is separate from plagiarism detection, which checks for copied source material.
Yes. Open the Advanced options panel and paste your rubric criteria into the Rubric field. The AI weights its scoring toward your rubric rather than generic academic standards. Rubric upload works on all tiers including the free tier. You can also paste your assignment prompt into the Assignment question field so the grader checks whether your document answers the question set.
Yes. The grader accepts .pdf, .docx, .doc, and .txt file uploads in addition to pasted text. Click the Upload file button above the input to attach your document.
Most documents are graded within 10 seconds. Pro and Premium plan holders receive 2x faster output.
No. Using an essay grader before submission is equivalent to asking a tutor or peer to review your draft. The grader does not write your document. It evaluates what you have written and tells you where to focus your revision. The final work is entirely yours. Check your institution's academic integrity policy if you are unsure about AI tool use in your specific context.
