Everything you need to know about GradingPen's AI essay grading platform — how it works, what it costs, and how to get started.
GradingPen uses large language model AI to read each student essay and evaluate it against your specific rubric criteria. You define the grading criteria and point values; the AI applies them consistently to every submission, generating criterion-by-criterion scores and detailed written feedback.
The teacher then reviews, personalizes, and approves the AI-generated grades before returning them to students. GradingPen is designed to augment teacher judgment — not replace it. You remain the final authority on every grade.
Research shows that well-configured AI grading tools align with human teacher scores within one grade band approximately 85-90% of the time on rubric-based analytical assessments. GradingPen is most accurate when rubric criteria are specific and well-defined.
Teachers review all AI grades before returning them to students. Most teachers find the alignment strong enough to trust after a brief calibration period — and the best workflow is "AI grades, teacher reviews" rather than "AI grades, teacher accepts blindly."
GradingPen accepts PDF files, Microsoft Word documents (.doc and .docx), Google Docs (via Google Classroom integration), plain text files (.txt), and RTF files. For handwritten essays submitted as photos or scanned PDFs, GradingPen's OCR technology extracts the text — accuracy depends on handwriting legibility.
Batch uploads of entire class sets are supported — you can upload 30 files at once and grade them all simultaneously.
AI grading processes one essay in approximately 15-30 seconds. A full class set of 30 essays is typically graded in 5-8 minutes. Teacher review of AI-generated feedback averages 60-90 seconds per essay, bringing total grading time (including review) to roughly 2-3 minutes per essay.
Compare this to traditional manual grading, which typically takes 15-20 minutes per essay. Most teachers report saving 70-80% of their grading time after switching to AI-assisted grading.
Yes. GradingPen's batch grading feature lets you upload an entire class set of essays simultaneously and grade them all at once. You can also import directly from Google Classroom, which automatically pulls all student submissions for a given assignment.
After AI grading completes, you work through a review queue to approve, edit, and personalize each grade before publishing to your gradebook or back to Classroom.
GradingPen works for any written essay or text-based assignment across all grade levels (K-12 and college) and subjects — English/ELA, history, social studies, science (including lab reports), philosophy, economics, ESL/ELL writing, and more.
You define the rubric criteria for your subject; the AI applies them. GradingPen includes rubric templates for common assignment types and supports AP, IB, Common Core, and state standards alignment.
GradingPen offers several plans for individual teachers, starting at approximately $12/month for 150 essays per month. Annual plans offer a significant discount compared to monthly billing. School and district plans are available with volume pricing.
See the full pricing breakdown at gradingpen.com/pricing — all plans include a free trial period with no credit card required to start.
Yes. GradingPen offers 15 free essay grades with no credit card required. You can sign up at gradingpen.com/register and start grading immediately.
The free trial gives you enough essays to test with a real class assignment and evaluate whether the time savings work for your teaching workflow before committing to a paid plan.
Grade banking is GradingPen's unique feature that lets teachers save unused monthly essay grades and carry them forward to future months — up to 750 banked grades. Most grading tools reset your monthly grade count on the 1st, even if you only used half your grades.
GradingPen's grade banking is built around how teachers actually work: lighter grading months in the middle of a unit bank grades for finals week and end-of-semester crunch time. Learn more about grade banking →
Yes. There are no long-term contracts or cancellation fees. Monthly subscribers can cancel at any time and retain access until the end of the paid billing period. Annual subscribers can cancel to prevent auto-renewal.
Your grading data remains accessible for 90 days after cancellation, giving you time to export any records you want to keep.
Yes. GradingPen offers school and district plans for 5 to 500+ teachers, with centralized billing, admin dashboards, usage reporting, and volume pricing. School plans typically run $8-10 per teacher per month at 10+ teachers.
Contact GradingPen for a custom quote for your district. Dedicated onboarding and professional development support is available for school accounts.

Department and university pricing is also available — contact GradingPen for academic institutional rates.
Yes. GradingPen is designed for FERPA compliance. Student essay data is processed securely, not shared with third parties, not used to train AI models, and can be deleted on request. GradingPen's data processing agreement is available for district review.
Schools can use GradingPen as a "school official" under FERPA's legitimate educational interest exception. Always verify compliance requirements with your district's legal counsel. Read our full FERPA guide →
No. GradingPen does not sell, share, or license student data to any third party. Student essay content is used only to generate grading feedback for the teacher who submitted the assignment.
Data is not used to train AI models. Full details are in GradingPen's privacy policy at gradingpen.com/privacy.
GradingPen stores data on servers located in the United States, using enterprise-grade cloud infrastructure with encryption at rest and in transit. Teacher accounts, rubrics, and grading records are retained for the duration of the subscription.
Student essay content is processed for grading and stored in the teacher's account. Teachers can delete student data at any time from the GradingPen dashboard.
Parents do not have direct access to GradingPen. Student work and feedback are visible to the teacher and, when published, to the student through whatever channel the teacher uses (Google Classroom, email, etc.).
FERPA governs parental access rights to student education records — this is managed at the school/district level, not by GradingPen. Schools should follow their standard FERPA procedures for parent record requests.

Yes. GradingPen includes an AI Tutor feature that students can use to get feedback on their own writing, ask questions about their feedback, and get step-by-step guidance on improving specific aspects of their essays.
The AI Tutor works as a writing coach — it explains why something isn't working and guides students through revision strategies without writing the essay for them. Visit gradingpen.com/tutor to try it.
GradingPen's AI Tutor is a conversational writing assistant for students. Students can paste their essay or assignment, ask questions about their teacher's feedback, request explanations of specific writing concepts, or get step-by-step revision guidance.
The AI Tutor is designed to teach, not to write for students — it provides explanations and strategies, not completed paragraphs. It's available at gradingpen.com/tutor.
Yes — GradingPen works on any modern mobile browser on iOS and Android. The full grading workflow (upload, grade, review, publish) is accessible on mobile.
However, the review queue is optimized for desktop use — reading and editing detailed feedback on a small screen can be tedious. Most teachers prefer to do the review step on a laptop or tablet and use mobile for quick checks or publishing grades.
In GradingPen, go to Rubrics → Create New Rubric. Add your criteria (e.g., Thesis, Evidence, Organization, Mechanics), set the point value for each criterion, and write descriptors for each score level. You can also start from a template and customize it, or paste an existing rubric and let GradingPen's AI format it automatically.
Rubrics are saved to your library and reusable across any assignment. Learn more about rubric building →
When you reach your monthly grade limit, you can upgrade your plan to a higher tier, wait for your monthly grade count to refresh, or draw on banked grades if you have them saved up.
GradingPen's grade banking feature lets you carry forward unused grades from lighter months to use during high-demand periods. You'll receive a notification before running out so you can plan ahead.
Yes. GradingPen is effective for SAT essay prep, ACT essay prep, AP Language and Composition, AP Literature, and state ELA standardized writing assessments. Build a rubric that mirrors the official scoring criteria for the specific test (College Board publishes AP rubrics; most state assessments publish scoring guides), and GradingPen will evaluate student practice essays against that standard.
Many AP teachers use GradingPen specifically for this use case — it's particularly effective for DBQ and LEQ prep in AP History courses.
GradingPen support is available by email at support@gradingpen.com and through the in-app chat widget. Response time is typically within 24 hours on business days.
A help center with tutorials, rubric-building guides, and troubleshooting articles is also available. For school and district accounts, dedicated account support is included.
