What if your mobile app could chat with AI in real time and generate a complete travel itinerary with beautifully structured cards?

In this practical, we're building an AI Travel & Itinerary Assistant App using React Native and modern AI SDKs!

Welcome to Lecture #34 of AI Mobile Engineer 2026 by The Techzeen, part of Phase 5: AI Mobile Engineering (Client Side).

WHAT WE BUILD
Vercel AI SDK: Streaming AI chat responses so users can see answers as they're generated.
OpenAI SDK + Zod: Generate structured itinerary data, including destination, trip duration and daily schedule, for rendering as app UI cards.
Modern UI/UX: A polished dark-themed interface using NativeWind and smooth animations with React Native Reanimated.
Physical Device Testing: Test the finished app on a real phone using Expo Go.

TECH STACK
React Native, Expo, Expo Router, Vercel AI SDK, OpenAI SDK, Zod, NativeWind and React Native Reanimated.
