AI Grading for Teachers

Frizzle uses AI to grade handwritten math assignments for teachers and transform them into rich analytics and differentiated assessment to help personalize instruction for every student. Teachers spend over 10 hours a week or 25% of all their work grading - Frizzle does it in minutes. Frizzle is the most valuable piece of software for teachers ever, as it eliminates the most time-consuming part of their workflow so they can focus on teaching. Frizzle was named an official White House AI Education Partner alongside OpenAI and Meta: https://www.whitehouse.gov/edai/. Frizzle was co-founded by Abhay Gupta and Shyam Sai, who met in high school over 10 years ago.

❌ The Problem

Teaching is one of the most important jobs in society, yet teachers are among the most overworked professionals. Many work 50–70 hours a week, often grading late into the night and on weekends.

Across the U.S., there’s a national teacher shortage where 1 in 8 teaching roles remain unfilled. Superintendents and principals consistently mention that teacher time is now their most valuable resource. But teachers lose 10+ hours every week just grading math assignments, time that could be spent supporting students. 25% of all their work is spent grading!

Existing grading tools handle essays or multiple-choice questions, but fail with math, especially handwritten step-by-step work. Classrooms are also moving back to pen and paper, but teachers are left with more paperwork than ever and no scalable way to manage it.

This has created a massive bottleneck in the classroom, adding to burnout and pushing talented teachers out of the profession.

Until now…

✅ Our Solution

At Frizzle, we’re a team of former math nerds and AI experts building the first system that actually handles math grading at scale.

Teachers simply upload or snap a photo of student work and instantly get back:

  • Accurate grading ✏️: Every step graded in seconds, whether it’s handwritten or typed.
  • Actionable insights 📊: A class dashboard highlighting where each student is struggling across assignments.
  • Student-friendly feedback 🧑‍🏫: Clear explanations that help students learn from their mistakes, not just see a score.

Frizzle eliminates the 10–15 hours a week teachers lose to grading, giving them time back to focus on what matters most - teaching.

🙏 Our Ask

If you answer “yes” to any of these, we’d love your help:

  • Do you know any math teachers that would benefit from an extra 10 hours in their week?
  • Do you know any schools or districts that would benefit from saving their teachers 10+ hours a week?
  • Have you scaled B2B SaaS into K–12 districts or worked closely with educators?

Your help can make a huge difference in bringing Frizzle to more teachers. Thank you!
