Sizzle is an AI‑powered learning platform that extracts knowledge components from uploaded PDFs, slides, or text and automatically creates adaptive practice questions for each component. The system tracks real‑time mastery with spaced‑repetition scheduling and analytics, and recommends supplemental videos, syncing progress across web and mobile devices. It enables high‑school and college students, as well as educators, to generate personalized study material without manual question creation.

Problem
Students often face dense textbooks, lecture slides, or unstructured notes that are difficult to parse into actionable study items, leading to inefficient revision and gaps in understanding. Creating personalized practice questions and tracking mastery manually is time‑consuming and prone to bias. Consequently, many learners struggle to achieve consistent, measurable progress across subjects.
Solution
Sizzle is an AI‑driven learning platform that ingests user‑uploaded study materials—such as PDFs, slides, or typed topics—and automatically decomposes them into granular Knowledge Components (KCs). For each KC, the system generates bite‑sized, adaptive exercises that adjust in real time based on the learner’s performance, reinforcing concepts where needed and advancing when mastery is demonstrated. Progress is visualized through a dashboard that highlights mastered skills, identifies weak areas, and suggests supplemental videos. The workflow requires only a few clicks: upload, let the engine parse the content, and start practicing, enabling students to study more efficiently without manual question creation. All interactions are secured and synced across devices, allowing learners to study anytime, anywhere.
Target Audience
Primary users are high‑school and college students preparing for exams or seeking deeper mastery of course material, as well as educators who want to provide scalable, personalized practice resources for their classes.
