What Sizzle AI does
Sizzle AI is a New York-based education technology company that developed a free AI-powered mobile and web learning application designed to help students solve academic problems step-by-step. The platform's core technical differentiator is a proprietary Knowledge Components (KC) architecture — grounded in learning science — that analyzes uploaded study materials such as study guides, lecture slides, and class notes, breaks content into the smallest units of understanding, and sequences adaptive practice exercises tailored to each learner's mastery state and knowledge gaps. The app serves individual students globally, with testimonial evidence spanning the United States, Switzerland, India, Ghana, Mozambique, Canada, and Nigeria, and primary use cases centered on STEM subjects including mathematics, physics, and chemistry.
The company operated on a product-led, freemium go-to-market motion, distributing the app free of charge through the iOS App Store, Google Play Store, and direct website downloads, supported by organic social channels (TikTok, Instagram, Facebook, Discord). No paid tiers, premium features, B2B pricing, or enterprise sales motion were disclosed. Founded by Jerome Pesenti — former VP of AI at Meta — Sizzle raised a $7.5 million seed round in August 2023 led by Owl Ventures and 8VC, grew to 1.7 million+ users, and was acquired by Campus, an online community college backed by Sam Altman and Shaquille O'Neal, on October 10, 2025. Following the acquisition, Pesenti transitioned to Chief Technology Officer of Campus and the founding team joined Campus's engineering function to integrate Sizzle's technology into the parent's online instruction platform.

Sizzle AI competitors and assessment
Company assessmentBroad incumbents
- Khan Academy (Khanmigo): Khan Academy is the largest free online education platform and launched Khanmigo, an AI tutor built on GPT-4 that provides step-by-step guidance across K-12 and early college subjects. It directly competes with Sizzle on AI-powered personalized tutoring for students and has Microsoft/OpenAI backing and a massive established user base.
- Chegg: Chegg is a publicly traded education technology company offering homework help, tutoring, and textbook solutions. It overlaps with Sizzle's exam prep and step-by-step problem-solving use cases and represents a broader incumbent monetizing similar student demand.
- Socratic by Google: Socratic is Google's AI-powered homework helper app that lets students upload questions and receive visual, step-by-step explanations. It is a direct free competitor in the mobile study-help category, backed by Google's search and AI infrastructure.
- Wolfram Alpha: Wolfram Alpha is a computational knowledge engine that solves math, science, and engineering problems with step-by-step breakdowns. It overlaps with Sizzle's STEM problem-solving use case and has a long-standing reputation as a learning tool among students.
Direct peers
- Photomath: Photomath is a mobile-first math solver that uses computer vision and AI to break down problems step-by-step, acquired by Google in 2023. It directly overlaps with Sizzle's core STEM problem-solving use case and shares the same mobile PLG distribution model.
