Pay once.
Grade when you need to.

Start with your 2 free Starter gradings to see the results for yourself. For a few essays of your own, Individual (3 gradings) is enough. For a single class or course, Class (25 gradings) is usually the better deal. If you grade several classes or buy for a department, Max (150 gradings) gives you the lowest price per grading. Longer submissions use more than one grading (21–60 pages: 2, over 60 pages: 3). You can buy any package as often as you like—your gradings simply add up.

No. Gradings from packages, your free Starter gradings, and referral bonus gradings never expire. They stay in your account until you use them—whether that's next week or next semester.

Simply buy another package whenever you need more—there's no plan to upgrade and no billing cycle to wait for. New gradings are added to your existing balance. You can also earn bonus gradings by referring colleagues! We'll notify you when you're running low.

No. Packages are one-time purchases, not a subscription—there's no auto-renewal and nothing to cancel. You only pay again if you decide to buy another package.

Each grading isn't just a quick AI response—it's a comprehensive, multi-stage analysis that rivals expert human evaluation. Behind every grade is an orchestrated network of specialized AI agents: an Investigator that meticulously extracts evidence from every page, an Evaluator that scores against calibrated benchmarks, an Auditor that catches inconsistencies and potential errors, and a Coach that crafts personalized improvement recommendations. This architecture requires multiple premium AI model calls working in concert, which is why we achieve 90%+ alignment with human experts. You're getting the equivalent of 15-20 minutes of expert grading time—that's exceptional value for feedback you can trust and defend.
