AI Tutor is a Next.js 16 learning workspace that turns chat into a guided study loop. The UI blends chat, document editing, quizzes, and flashcards, while the AI layer is routed through a shared prompt registry that chooses between OpenAI, Anthropic, and Google models.
The app separates auth and chat flows, persists history through Drizzle on Neon, and runs NextAuth with Google/Resend/Keycloak providers. Voice sessions run on LiveKit with transcript syncing and noise filtering, so the same study flow works in text or audio mode.
