# Frizzle > Frizzle is the operating system for math classrooms. Students keep working on paper; teachers snap a stack of worksheets with a phone, document camera, or scanner, and Frizzle reads every page — grading handwritten K-12 math work step by step, surfacing misconceptions, and turning paper into live class and student analytics. - Grades handwritten math work, including multiple valid solution paths, and gives step-level feedback rather than a single score. - Reads a full class in roughly eight minutes; capturing a stack takes about thirty seconds. - Tracks named misconceptions and prerequisite gaps across a class, so teachers can see who is stuck and why. - Aligns to standards frameworks including CCSS, TEKS, and 30+ state frameworks, and to common curricula such as Eureka, Illustrative Math, Saxon, Big Ideas, and enVision. - Free forever for individual teachers, with no credit card required. Paid plans add higher worksheet volume, analytics, and school/district administration. - Student work is never used to train models. Frizzle is FERPA and COPPA compliant, with AES-256 encryption at rest and TLS 1.3 in transit. ## Plans - Free: $0 forever, up to 50 worksheets per month (one worksheet = one student page). - Pro: $24/month, or $200/year (about $16.67/month), up to 1,000 worksheets per month. Adds class and student analytics, misconception tracking, and custom rubrics and grading scales. - Institution: custom pricing, unlimited worksheets, admin dashboards, Google Classroom and Canvas integrations, SSO/SAML/Clever/ClassLink, and a custom DPA. ## Pages -
