Travie.ai – AI-Powered Travel Planning Platform
Inspiration
Planning a trip should be exciting—but in reality, it’s stressful. People juggle dozens of tabs, outdated blogs, and scattered recommendations.
We asked ourselves:
“What if planning a trip could be as easy as getting all the planning and booking details in seconds?”
That vision inspired us to create Travie.ai, an AI-powered travel planning platform that combines Google Gemini’s intelligence with Google Maps data for accurate, real-time travel experiences.
What it does
Travie.ai creates personalized, day-by-day itineraries in seconds using Google Gemini for AI-driven recommendations and the Google Maps Platform for precise, real-time data.
With Places API, we provide verified attractions, restaurants, and hidden gems. Users can:
- Plan and customize their trips
- Access real-time location details like hours, ratings, and directions
- Book everything—flights, stays, and activities—all in one place
Our goal: make travel planning effortless, smart, and inspiring.
How we built it
AI Engine

Key Formula:
$$ \text{User Experience} = \text{AI Intelligence (Gemini)} + \text{Google Maps Accuracy} + \text{One-Stop Booking} $$
Challenges we ran into
- Performance: Initial generation took ~22 seconds; optimized to ~5 seconds using caching and pre-fetching
- Data Filtering: Places API returns many results; created custom ranking for relevance
- Route Optimization: Sequencing multi-day trips across multiple cities required advanced algorithms
- Fusion of LLM + Map Data: Ensuring AI-generated plans align with real-world data (locations, opening hours, distances)
Accomplishments that we're proud of
- Built an MVP combining Gemini and Google Maps in a real-world application
- Reduced itinerary generation time by 77%
- Delivered a user-friendly interface for end-to-end trip planning and booking
