🚗 TravellerAI: Smart Road Trip Assistant

Inspiration

TravellerAI was inspired by my own experiences and challenges planning road trips across India.

As a solo developer and frequent traveler, I often found it difficult to:

  • Discover the best food stops, fuel stations, and hotels along unfamiliar routes.
  • Get real-time, actionable recommendations tailored to my travel style (family, speedy, relaxed).
  • Plan trips that adapt to weather, vehicle needs, and personal preferences.

I wanted to build an assistant that not only solves these problems, but also makes road trips more enjoyable, safe, and memorable for everyone.

What I Learned

  • Google Maps API: Deep integration for route planning, POI (Point of Interest) search, and real-time data.
  • React & TypeScript: Building a scalable, maintainable, and responsive frontend.
  • Smart Filtering: Aggregating, filtering, and ranking POIs for relevance and quality.
  • AI Chatbot Integration: Creating a conversational interface that provides actionable, context-aware travel advice.
  • Performance Optimization: Running multiple API calls in parallel, caching, and adaptive search strategies.
  • User Experience: Designing for both mobile and desktop, and supporting dark/light themes.
  • Full-Stack Ownership: Managing every aspect of the project, from architecture to deployment, as a solo developer.

How I Built It

🖥️ Frontend

  • Built with React and TypeScript for type safety and modularity.
  • Tailwind CSS for responsive, modern UI.
  • React Context API and hooks for state management.

🧠 Smart POI Engine

  • Uses Google Maps Places API to search for:
    • Restaurants 🍛
    • Cafes ☕
    • Hotels 🏨
    • Fuel Stations ⛽
  • Adaptive Search: Expands radius and relaxes filters when results are sparse.
  • Ranking Logic:
    • Relevance to route
    • Review count
    • Star rating

🤖 AI Chatbot

  • Integrated with Together.ai, Cohere, and Hugging Face.
  • Chatbot capabilities:
    • “How many fuel stops will I need?”
    • “Suggest cafés rated above 4.5 near my route.”
    • “What's the fuel cost for my trip?”
  • Returns route-specific, actionable results.
  • No OpenAI dependency for full control & cost-efficiency.

🌤️ Weather Integration

  • Uses OpenWeather API for:
    • Route-based forecasts
    • Rain prediction messages:
      > "You might get stuck in rain at 3PM — stop early?"

🚙 Trip Summary

  • Personalized based on:
    • Vehicle mileage
    • Tank capacity
    • Fuel type (petrol/diesel)
  • Shows:
    • Number of fuel stops
    • Estimated fuel usage
    • Fuel cost using live rates

🌍 Other Features

  • ✅ Dark & Light mode toggle
  • ✅ Fully responsive for mobile
  • ✅ IPFS support for saving & sharing trip plans
  • ✅ Sleek, minimal, emoji-enhanced UI

😮 Challenges Faced

API Limitations

  • Google Places API sometimes gave inconsistent results in rural areas.
  • Solved via adaptive search radius and relaxed filters.

Performance

  • Sequential API calls slowed things down.
  • Fixed by parallelizing trip, weather, and POI requests.

Chatbot Relevance

  • Initially chatbot gave general advice.
  • Refined to link AI chat with map/POI context for precise answers.

Voice Input

  • Removed voice feature for a more minimal UI and faster UX.

Solo Development

  • Managed everything from code to UI/UX to deployment alone.
  • Challenging but extremely rewarding.
