An AI-powered oral exam simulator designed to help college students prepare for high-stress viva and defense-style exams through timed, spoken practice. The platform allows users to upload lecture slides, including PDF and PPTX files, which are parsed locally to reduce costs before generating primary and adaptive follow-up questions. Using Gemini-powered AI, stern text-to-speech audio, voice transcription, and a 30-second countdown, the product replaces passive reading with active exam-style drills. Built as a mobile-first EdTech product with a React/Vite and TypeScript codebase, Cloudflare Workers, D1 Database, Firebase Auth, and Stripe subscriptions, the platform offers a low-cost infrastructure setup and a clear path for marketing-led growth.
