5-Category Rubric Breakdown
Every student gets individual scores for Content & Ideas, Organization, Grammar & Mechanics, Style & Clarity, and Evidence & Support. The rubric breakdown shows exactly where each student excelled or struggled, making feedback and grade conversations objective.
CSV Export for Gradebooks

How to Use the AI Grading Tool
Grade a full class of essays in 4 simple steps
Paste Your Student Essays (Batch Format)
Copy all student essays into the batch input field. Use numbered format (1. John Smith, 2. Jane Doe) or separator format (Student: Name, --- divider). Include student names with each essay. The tool handles 1-25 essays per batch and auto-detects the format.
Configure Your Grading Rubric
Pick your grading scale (A-F, percentage, 10-point, 100-point), essay type, grade level, rubric weighting (equal, content-heavy, mechanics-heavy, style-heavy), and strictness (lenient, balanced, strict). Save the rubric with a custom name to reuse it later, or load a previously saved rubric.
Grade & Export to CSV
Click Grade All Essays and the AI processes each student sequentially with consistent rubric application. View all grades in a table with rubric breakdowns and justifications. Click Export CSV to download a gradebook-ready file with student names, overall grades, category scores, and justifications.
Who Uses the AI Grading Tool?
Teachers across all grade levels use the AI Grading Tool for fast, consistent, objective batch grading
High School English Teachers - Grade 5 Sections
High school teachers with 100+ essays per week use the batch AI grading tool to handle large stacks in hours instead of days. Grade one section (20-25 essays) at a time, save the rubric for that assignment, and load it for the next section. Consistent rubric application across all 5 sections means fair grading for every student.
College TAs - Intro Composition Sections
TAs grading 50-75 intro composition essays per week use the batch grading tool for first-pass scoring. The 5-category rubric breakdown identifies which essays need detailed manual review and which are clear A or C papers. Export to CSV and import grades into the LMS gradebook with one upload.
Homeschool Educators - Grade Multiple Students
Homeschool parents teaching 3-5 kids use the AI grading tool for objective scoring without bias. The rubric breakdown shows exactly where each child needs improvement. Save custom rubrics for each subject (argumentative essays, research papers, creative writing) and reuse them throughout the year.
Private Tutors - Batch Grade Weekly Assignments
Tutors working with 10-20 students per week use batch AI grading to handle weekly essay submissions in one session. Grade all students at once, export to CSV for record-keeping, and use the rubric justifications as talking points in one-on-one sessions. The consistent scoring helps track student progress over time.
Tips for Best Results
Get the most accurate and useful grades from the AI Grading Tool
Format Batch Input Correctly for Smooth Parsing
Use numbered format (1. Name) or separator format (Student: Name, --- divider) to ensure the tool parses every essay correctly. Include the full student name with each essay. Test with 2-3 essays first to verify the format works before pasting a full batch of 20-25.
Save Custom Rubrics for Recurring Assignment Types
Create and save rubrics for each assignment type you use regularly (argumentative essays, research papers, in-class writes). Load saved rubrics to grade future assignments with one click. This eliminates the need to reconfigure settings every time and ensures rubric consistency across the semester.
Start with Balanced Strictness, Adjust If Needed
Balanced grading strictness matches typical teacher standards and produces realistic grades for most assignments. Use Lenient for early-semester diagnostic essays or elementary students. Use Strict for AP, IB, or honors sections where high standards are expected. Stick with one strictness level across a grading period for consistency.
Use CSV Export for Gradebook Entry
After grading, click Export CSV to download a file with student names, overall grades, and rubric category scores. Open the CSV in Excel or Google Sheets, verify grades, and copy-paste into your LMS gradebook. The CSV format saves 10-15 minutes of manual data entry per batch.
Grade One Section at a Time for Best Results
Instead of pasting 100 essays at once, grade one class section (20-25 essays) per batch. This keeps the batch size manageable, makes it easier to review results, and lets you adjust rubric settings between sections if needed. Sequential batches also reduce API errors from oversized requests.
