Alternatives to Frizzle

Frizzle is an AI-powered grading tool that uses computer vision and large language models to grade handwritten math work with 97% accuracy. It provides teachers with standards-level formative analytics aligned to Common Core State Standards, showing which standards each student and class has actually mastered. The system includes a confidence-interval mechanism that flags uncertain grades for human review, ensuring reliability.

Frizzle is designed for math teachers, instructional coaches, and school districts looking to reduce grading time and improve data-driven instruction. It is currently live in over 30 schools and districts, including college math pilots at Vanderbilt and Arizona State University. The platform serves both K-12 and higher education settings where handwritten math work is common.

Key features include 97% accurate AI grading of handwritten math, a confidence-interval system that flags uncertain answers for human review, and standards-level analytics mapped to CCSS. The workflow allows students to write on paper while teachers photograph or copy the work, with results returned within hours. This replaces the 10-15 hours per week teachers typically spend grading by hand.

Frizzle is built for use in schools and districts, which typically require compliance with student data privacy regulations such as FERPA. The platform processes handwritten math work and returns analytics without storing unnecessary personal data. As a tool used in multiple districts and university pilots, it follows standard educational data security protocols.
