Frequently Asked Questions

How accurate is the AI grading?

Our AI maintains a 95%+ accuracy rate compared to human graders. It uses advanced language models (Claude) that understand context, nuance, and subject-specific requirements. However, we always recommend reviewing AI feedback as a learning tool rather than a final grade.

What's the difference between Rubric-Based and AI Smart Grading?

Rubric-Based grading requires you to provide specific criteria and is best for structured assignments with clear requirements. AI Smart Grading uses natural language - just describe what you need graded, and the AI automatically generates appropriate criteria and provides feedback. Both are thorough and detailed!

What subjects can RubrifyAI grade?

RubrifyAI can grade virtually any subject! Our AI automatically detects whether your work is STEM (math, science, engineering), Humanities (English, history, social studies), or General (art, music, PE, etc.) and applies appropriate expertise.

Is my work kept private?

Absolutely! Your submissions are completely private and secured. We use industry-standard encryption and never share your work with third parties. You can delete your submissions at any time.

How much does it cost?

RubrifyAI offers a free tier with 10 gradings per month. Premium plans start at $5/month for unlimited gradings. We also offer special pricing for schools and educational institutions. Students can always access basic features for free!

Can teachers use this for their classes?

Yes! Many teachers use RubrifyAI to provide quick feedback on drafts, save grading time, and ensure consistent evaluation. We offer school licenses that allow entire classes to access the platform. Contact us for educational pricing.

How long does grading take?

Most assignments are graded in under 30 seconds! The AI analyzes your work, compares it to the rubric or generates criteria, and generates detailed feedback almost instantly. No more waiting days or weeks for grades!
