Skyguy - Your Travel Buddy

Inspiration

Trip planning is a tab nightmare. Flights here, hotels there, a spreadsheet to track which combo fits the budget. We wanted to kill that completely. Describe your trip in one message, get a real bookable plan back. That's Skyguy.

What it does

Skyguy is a conversational travel agent that handles the full pre-booking flow in one shot:

  • One sentence, full trip. "5 days in Tokyo in April for two, around €3k" returns flights, hotel, and a rental car as one priced bundle.
  • Parallel search, unified reasoning. Flights, hotels, and cars are fetched together. Swap the hotel neighborhood and it knows the car pickup might need to move too.
  • Persistent preferences. Cabin class, hotel stars, bags, transmission, avoided airlines. Set once, applied everywhere.
  • Saved trips and conversations. Pick up last week's half-planned trip exactly where you left it.
  • Voice input for planning on the go.

How we built it

  • Frontend: React 18 + Vite + TypeScript, Fully themed with CSS variables, no hardcoded colors. Built with partially coding assistant for frontend.
  • Backend: Supabase for auth, Postgres, RLS, and edge functions. Conversations, messages, favorites, and travel preferences all live in typed tables with row-level security.
  • Travel data: Skyscanner API handles flight search. Hotels and car rentals run through a seeded catalog with real-shaped availability data so results always feel complete.
  • AI orchestration: A travel-chat edge function with tool-calling across flights, hotels, and cars. The model decides which tools to call, we execute them server-side, then stream a structured bundle back to the chat.
  • Voice: A transcribe-audio edge function handles speech-to-text in the composer.

Challenges

  • Bundling async results. Flights, hotels, and cars return with different shapes and currencies. Collapsing that into one trip card with a single total was harder than expected.
  • Currency handling. Every supplier returns its own currency. We convert on the fly to the user's preferred one.
  • RLS without recursion. Roles in a separate table with a SECURITY DEFINER has_role() function keeps policies clean.

What we're proud of

  • A full Tokyo trip (flights + hotel + car, €2,765) generated from a single chat message.
  • Zero hardcoded colors anywhere. Light and dark mode just works.
  • Typed, CORS-strict edge functions with graceful fallbacks.
  • Preferences that actually change results. Set "direct flights only" once and every future search respects it.

What's next

Real bookings, group trip planning, price drop alerts, day-by-day itineraries, and more transport types like trains, ferries, and transfers. All in the same bundle.
