What is an AI Essay Grader?

An AI Essay Grader predicts your essay's grade — A-F letter, percentage, or point score — with a 5-category rubric breakdown and clear justification. It's built for two jobs: students who want to know their likely grade before submitting, and teachers grading at scale who need a consistent rubric-based first pass. Paste in your essay, pick a grading scale, and you'll get an objective grade in seconds with no sign-up.

Choose from 4 grading scales (A-F, percentage, 10-point, 100-point), 8+ essay types, all academic levels, customizable rubric weighting, and calibration against high school honors, AP/IB, college intro, college advanced, or graduate seminar standards. The grade comes with a rubric table, brief justification, and a clear explanation of where the score comes from. For revision feedback or sentence-level rewrites on the same draft, use the AI Essay Reviewer instead.

Key Features

Free Essay Grader - Multiple Scales

Grade essays free with 4 grading scales using our AI essay grader. Letter Grades (A-F) for traditional academic assessment, Percentage (0-100%) for numerical scoring, 10-Point Scale for simplified grading, and 100-Point Scale for detailed point-based evaluation. The rubric scoring adapts to whichever scale you choose so totals stay consistent.

Comprehensive Rubric-Based AI Grading

Our AI essay grader scores 5 rubric categories - Content & Ideas, Organization, Grammar & Mechanics, Writing Style, and Evidence & Support. You get an individual score per category plus a total grade, displayed as a clean rubric table. The breakdown shows exactly which categories pushed the grade up or down.

8+ Essay Type Support

The AI essay grader handles all academic essay types - Argumentative, Analytical, Narrative, Research, Persuasive, Comparative, Expository, and Personal Statements. Scoring criteria adapt automatically to match the genre, so an argumentative essay is scored on thesis and evidence while a narrative is scored on storytelling and arc.

Detailed Grade Justification

Every grade from our AI essay grader comes with two-paragraph justification quoting brief snippets from your essay. You see exactly why the score was assigned, which passages pushed it up, and which held it back. The result is transparent, evidence-based grading both students and teachers can defend.

Grade Prediction by Standard

Calibrate your predicted grade against high school honors, AP/IB, college intro, college advanced, or graduate seminar standards. The same essay grades differently at different levels — pick the one that matches your course and see the realistic score for that context.

Tips for Best Results

Select Correct Essay Type

Argumentative essays are scored on thesis and evidence, narrative on storytelling and voice, research on citations and analysis. Picking the wrong type causes misaligned rubric scoring. Pick the type that fits your writing for the most accurate predicted grade.

Match Academic Level Correctly

High school expectations differ from graduate level. The rubric standards adjust based on the level you select — what earns an A in high school may score lower at graduate level. Setting the right level ensures the grade is calibrated correctly.

Use Calibration Standard for Course Context

Pick the calibration standard that matches your actual course — AP/IB for AP exam prep, college advanced for major coursework, graduate seminar for grad school. The same essay grades differently at different standards, so calibration accuracy is what makes the predicted grade realistic.

Use Balanced Strictness First

Start with Balanced grading strictness. Lenient is too generous to be predictive, and Strict may understate the likely grade. Balanced reflects typical teacher standards. Adjust to Strict only if your professor is known for tough grading.

Focus on Lowest-Scoring Rubric Category

After grading, look at which rubric category scored lowest. Improving your weakest category yields the biggest grade jump. If you want sentence-level rewrites to improve that category, take the draft to the AI Essay Reviewer and come back here to re-grade.

Re-Grade After Revisions

Use the AI essay grader iteratively — grade, revise, then re-grade to measure score change. Scoring is consistent across attempts so you can track grade movement reliably. The fastest way to raise the predicted grade is Reviewer-then-Grader cycles.
