Voyage Virtuoso
Intelligent, AI-powered itinerary generation and trip management for Android.
Project Idea & Overview
An AI-powered travel planning application that generates personalized itineraries using Gemini AI. Built with Jetpack Compose using MVI architecture and Ktor for networking.
The Problem
Travelers often spend hours research destination activities, budgeting, and organizing daily schedules across multiple browser tabs and notes apps. Existing travel apps lack personalized real-time AI adjustments based on user preferences, time constraints, and destination dynamics.
The Solution
Voyage Virtuoso leverages Google's Gemini AI combined with a modern MVI Android architecture to transform plain-text travel prompts into structured, multi-day itineraries. Users get tailored day-by-day schedules with activity recommendations, maps integration, budget breakdowns, and instant AI re-planning.
Architecture & Patterns
- MVI (Model-View-Intent) architecture for unidirectional data flow and predictable UI states.
- Ktor Client for lightweight asynchronous HTTP networking with Kotlin Serialization.
- Kotlin Coroutines & StateFlow for non-blocking asynchronous operations and reactive UI updates.
- Clean Architecture layers (Domain, Data, UI) enabling testability and separation of concerns.
Key Features & Capabilities
Personalized AI Itineraries
Generates custom day-by-day trip schedules based on budget, travel style, companions, and trip duration.
Dynamic Smart Re-planning
Allows users to modify plans on the fly — ask the AI assistant to substitute activities or adjust schedules dynamically.
Reactive Compose UI
Built with Material Design 3 and smooth Jetpack Compose animations for fluid navigation and dark mode support.
Offline Sync & Local Caching
Stores generated itineraries locally so travelers can access schedules even without active cellular data.
Technologies Used
