Grade more.
Stress less.

One grade = one student submission graded by the AI. Whether it's a 500-word essay or a 3-page lab report, it counts as one grade. Batch uploads (30 essays at once) count as 30 grades toward your monthly quota.

Every teacher plan comes with 250 base grades/month. At the end of each month, any unused grades are automatically saved to your Grade Bank — up to 750 grades maximum. When you've used your base quota, GradingPen pulls from your bank automatically. Nothing expires, nothing resets to zero at midnight. Read the full story →

All of them. GradingPen was built to grade any written assignment — English essays, history papers, science lab reports, math explanations, foreign language writing, social studies reports, coding documentation, and more. If a student wrote it, GradingPen can grade it.

Both. Individual teachers can purchase GradingPen on their own — paying out of pocket or through a classroom fund (it's an eligible classroom expense in most districts). School and District plans are available for institutions that want site-wide access, admin controls, and a single invoice.

You'll get a warning at 80% usage so you're never surprised. If you hit your limit, GradingPen checks your banked grade balance first — unused grades from previous months roll over automatically (up to 750 saved). If you've used those too, you can instantly buy an add-on pack: 50 grades for $4.99, 100 for $8.99, or 250 for $19.99. You're never hard-blocked mid-semester.

GradingPen works for K–12, college, and graduate-level writing across every subject — English, history, science, social studies, foreign language, philosophy, law, medicine, and more. You set the grade level and rubric, and the AI calibrates its feedback accordingly. Elementary essays and graduate dissertations both get appropriately leveled feedback.

Yes! GradingPen connects directly to Google Classroom. Teachers authorize their Google account once, then import student submissions directly from any assignment — no copy-pasting, no manual uploads.

For most essay types, GradingPen's AI grades correlate strongly with experienced teacher scores — within 5–10% on most rubric dimensions. The AI evaluates thesis strength, argument structure, evidence quality, writing mechanics, and critical thinking, just as a teacher would. Crucially, you always have final say: every grade is reviewable, editable, and overridable before it reaches a student.

Both. You can paste in your existing rubric exactly as-is, build one from our library of 500+ templates, or create one from scratch using our AI Rubric Builder. The AI grades against whatever criteria you define — and you can save and reuse rubrics across assignments and classes.
