AI Essay Grader for Teachers

Automatically grade student essays with detailed, growth-oriented feedback. Get rubric-aligned scores, specific sentence-level revision suggestions, and strengths analysis — all in seconds. Use on single essays or grade your entire class at once.

Example Feedback

Strengths

Your opening "uniforms strip away individuality" is a strong hook. The counterargument in paragraph 3 shows sophisticated thinking.

Areas for Growth

Paragraph 2 needs a topic sentence before jumping into evidence. Conclusion restates your thesis but doesn't extend the argument — answer "so what?"

Revision Example

Original: "Uniforms cost money and students don't like them."
Revision: "Research shows uniforms reduce behavioral issues, even though students initially resist the change."

Frequently Asked Questions

How does the AI essay grader work?
Paste your student's essay and optionally provide a rubric or grading criteria. Claude analyzes the work against standards or your custom criteria and provides detailed feedback with specific quotes from their writing, sentence-level revision suggestions, strengths, and growth areas.
What makes this different from ChatGPT?
LessonDraft's grading tool is built specifically for classroom feedback with growth-oriented language, detailed quotes from student work, actionable revision suggestions, and support for multiple essays at once. It's designed for teachers, not general text analysis.
Can I use my own rubric?
Yes. Paste your rubric or grading criteria and the AI will score each criterion individually and align all feedback to your specific expectations and standards.
Can I grade multiple essays at once?
Absolutely. Use our Bulk Essay Grading tool to grade an entire class at once — just paste all essays separated by '---' and get detailed feedback for each student in one generation.
Does the AI replace teacher grading?
No. The AI generates draft feedback that you review and edit before sharing with students. It saves you hours on the initial feedback draft while you maintain full control over the final grade and comments.
Is the essay grader FERPA-compliant?
Yes. Student work you submit is processed through Claude (Anthropic's API) and not stored by LessonDraft. We recommend using student ID numbers instead of names for additional privacy. Never include sensitive health or discipline information.
What grading scales are supported?
The grader supports A-F letter grades, percentages, points-based systems, standards-based grading (1-4), pass/fail, and feedback-only modes. Choose what matches your classroom.
How long does it take to grade essays?
Single essays are graded in 30 seconds. Bulk grading an entire class (20-30 students) takes about 45 seconds. Time varies with essay length and rubric complexity.
Is the essay grader free?
Yes, and it's incredibly generous. Free users get 15 generations per month. A bulk grading session counts as 1 generation, even if you're grading 30+ essays. It's our way of putting your time back in your hands.
What file formats are supported?
Paste text directly, or attach PDFs and images. The AI reads handwritten essays from photos and typed work from any format.
