Frizzle

Frizzle is the operating system for math classrooms, designed to transform how teachers understand and respond to student learning. By combining advanced computer vision and large language models, Frizzle reads handwritten student work from paper, analyzes every step of the problem-solving process, and delivers granular, standards-aligned insights in real time. This product is built for K-12 math teachers, instructional coaches, and school or district administrators who want to move beyond simple answer checking and into deep, actionable understanding of student thinking. Frizzle works seamlessly with existing classroom workflows. Students continue writing on paper with pencils, no tablets or logins required. Teachers simply photograph a stack of papers or run them through a copier. Within minutes, Frizzle processes the work, automatically links each page to the correct student, and generates live dashboards showing who is stuck, which misconceptions are spreading across the class, and exactly what each student needs to learn next. The core value proposition is reclaiming time and unlocking data. Teachers spend 10 to 15 hours each week grading by hand. Frizzle eliminates that burden, giving educators back their evenings and weekends while providing a level of insight into student thinking that has never been possible at scale. It identifies 147 named misconceptions across K-12 math, maps student performance to standards like CCSS and TEKS, and provides confidence-interval grading that flags uncertain results for human review, achieving 97% accuracy. Frizzle is already live in over 30 schools and districts, including a college math pilot at Vanderbilt and Arizona State University. It is FERPA and COPPA compliant, with end-to-end encryption, and student work never trains the model. For teachers, it means ending the Sunday grading grind. For coaches, it means having specific, standards-level conversations instead of generic ones. For districts, it means cutting math screen time without losing the classroom-level data they need to drive improvement.

Handwriting Recognition and Step-Level Analysis

Frizzle reads any handwriting, from neat print to messy cursive to scribbled sideways notes. It does not just check final answers. Its computer vision parses every step of a student's work, understanding multiple solution paths and giving partial credit where it is due. For example, if three students solve an equation in three different ways, Frizzle credits all three approaches, recognizing that different brains can arrive at the same correct answer. This step-level feedback pinpoints exactly where thinking went off track, turning a simple "wrong" into a specific, teachable moment.

Real-Time Misconception Detection

Frizzle surfaces what is really happening in the classroom by identifying 147 named misconceptions across K-12 math, each mapped directly to educational standards. When a student makes a sign error or struggles with the distributive property, Frizzle flags it immediately. It also performs prerequisite tracing, recognizing when a seventh-grade error is actually a gap from fourth grade. Teachers see which misconceptions are spreading through the class in real time, allowing them to intervene before small misunderstandings become large learning gaps.

Standards-Aligned Formative Analytics

Instead of waiting for spring assessments to understand student progress, Frizzle delivers live, standards-level formative analytics every time a teacher snaps a stack of papers. Performance is automatically mapped to CCSS, TEKS, and over 30 other state frameworks. Teachers, coaches, and administrators can see exactly which standards each class and each student has mastered, which are developing, and which are at risk. This granular data transforms coaching conversations from generic check-ins into specific, data-driven discussions about what to reteach and how to improve.

Confidence-Interval Grading and Human Review System

Frizzle achieves 97% accuracy in grading handwritten math, but it is designed to be transparent about uncertainty. Every grade comes with a confidence interval. When the system is less certain about a particular response, it flags that paper for human review. This ensures that teachers maintain oversight and can make the final call on ambiguous work. The system shows its work by linking every flag back to the exact stroke on the page, so teachers can see exactly what Frizzle saw and make informed decisions quickly.

Reclaiming Teacher Time from Grading

A middle school math teacher spends every Sunday afternoon grading a stack of 120 quizzes. Each quiz takes about two minutes to check for correct answers and partial credit. That is four hours of repetitive work every weekend. With Frizzle, the teacher photographs the entire stack in about 30 seconds. Within eight minutes, Frizzle has read every page, graded each problem, and identified which students made sign errors and which struggled with factoring. The teacher now spends Sunday planning targeted interventions instead of marking papers, reclaiming 10 to 15 hours per week for lesson design and student support.

Providing Real-Time Intervention for Struggling Students

A high school Algebra I teacher notices during a lesson that several students seem confused about solving two-step equations. Instead of waiting for the unit test to confirm her suspicion, she collects the day's exit tickets and snaps a photo with her phone. Within minutes, Frizzle's dashboard shows that 40% of the class made the same distributive property error. The teacher immediately adjusts tomorrow's lesson plan to include a targeted mini-lesson on distribution, addressing the misconception before it solidifies. Students who showed mastery receive enrichment work, while those flagged as at risk get small group support the next day.

Driving Data-Driven Coaching Conversations

An instructional coach visits a middle school math department. Instead of a vague conversation about how things are going, the coach pulls up Frizzle's school-level dashboard. She can see that Period 2 is struggling with linear equations while Period 5 has mastered them. She can identify that a specific misconception, combining like terms incorrectly, is appearing across three different teachers' classrooms. The coach now has concrete data to lead a professional learning community session focused on strategies for teaching combining like terms, making the coaching conversation specific, actionable, and directly tied to student work.

Enabling District-Wide Curriculum and Equity Analysis

A district curriculum director wants to know if the new Eureka Math curriculum is working better than the previous Illustrative Math adoption. With Frizzle deployed across multiple schools, she can aggregate anonymized data to see which standards students are mastering and where they are struggling across the entire district. She can also run equity dashboards to spot performance gaps that emerge between different demographic groups, allowing the district to allocate resources and support where they are needed most. This live nervous system for math replaces waiting for end-of-year test results with immediate, actionable data.

Frizzle is free for individual teachers. There is no credit card required to start. For schools and districts, custom pricing is available based on the number of students and the specific needs of the institution. Frizzle is already live in over 30 schools and districts, including a college math pilot at Vanderbilt and Arizona State University. To get started, teachers can sign up for free on the Frizzle website, and school or district leaders can contact the sales team for a personalized quote and demonstration.

How does Frizzle work with my existing classroom workflow?

Frizzle is designed to slot into the way teachers already teach. Students continue to write on paper with pencils. There are no tablets, no student logins, and no migration to a new digital platform. Teachers simply collect the papers, photograph them with a phone, document camera, or scanner, and upload them to Frizzle. The system automatically reads the handwriting, links each page to the correct student, and begins processing. The entire process for a class of 28 students takes about 30 seconds to snap and eight minutes for Frizzle to return results. Your classroom routine does not change, but the data you get from it transforms completely.

Is Frizzle accurate, and what happens when it is unsure?

Frizzle grades handwritten math with 97% accuracy. It uses a confidence-interval system to assess its own certainty for every response. When the system is highly confident in a grade, it records the score automatically. When it encounters ambiguous handwriting or an unusual solution path that lowers its confidence, it flags that specific paper for human review. Teachers can then quickly look at the flagged work and make the final determination. This system ensures that teachers maintain full control and oversight while still saving massive amounts of time on the vast majority of grading that Frizzle handles correctly.

How does Frizzle protect student privacy and data?

Privacy is foundational to Frizzle's design, not an afterthought. The product is fully FERPA and COPPA compliant, and it undergoes SOC 2 Type II audits annually. All data is encrypted with AES-256 at rest and TLS in transit, ensuring end-to-end security. Critically, student work never trains Frizzle's model. The data belongs to the school or district and stays under their control. This commitment to privacy allows schools to adopt Frizzle with confidence, knowing that their students' sensitive academic information is protected by the highest industry standards.

What curriculum and standards does Frizzle support?

Frizzle is curriculum-agnostic, meaning it can read and analyze student work from any math program. Whether your school uses Eureka Math, Illustrative Mathematics, Saxon, or a custom district curriculum, Frizzle adapts to the content. For standards alignment, Frizzle supports CCSS, TEKS, and over 30 other state frameworks. It automatically maps student performance to the relevant standards, showing exactly which skills have been mastered and which need reteaching. This flexibility makes Frizzle a valuable tool for any school or district, regardless of their chosen curriculum or state standards.

How fast does Frizzle process a stack of papers?

The speed is one of Frizzle's most transformative features. Snapping a stack of papers with a phone or scanner takes approximately 30 seconds for a typical class of 25 to 30 students. Once uploaded, Frizzle processes the entire stack and returns results in about eight minutes. This means a teacher can collect papers at the end of a period, snap them during a passing period, and have complete, standards-aligned analytics ready before the next class begins. The speed enables truly formative assessment, where data from today's lesson can inform tomorrow's instruction without any delay.
