The Challenge
Planning a trip is often stressful and fragmented across dozens of tabs (flights, hotels, maps, blogs). The founders wanted to solve the "Paradox of Choice" in travel. The technical challenge was to take unstructured, vague user intent (e.g., "I want a romantic trip to Italy") and convert it into a deterministic, bookable itinerary data. Existing AI models would often hallucinate non-existent hotels or illogical routes, leading to user frustration.
Our Solution
We built a sophisticated "Reasoning Engine" using OpenAI's GPT-4, wrapped in a Next.js application. We engineered a prompt chain that first validates constraints, then generates a skeleton itinerary, and finally cross-references every suggestion with Google Places API to ensure the location exists and is open. The UI presents the plan as an interactive timeline on a map, not just a text list. We also built a "Collaboration Mode" using websockets, allowing friends to edit the itinerary together in real-time like a Google Doc.
Key Features
- AI-Powered Trip Generation
- Interactive Map View
- Save & Share Itineraries
- Budget Estimation
The Result
The app went viral on Product Hunt, gaining 10,000 active users in the first week. The "Hallucination Rate" (fake places) dropped to near zero due to our verification layer. User retention is 45% (exceptionally high for travel apps), and the "Share Itinerary" feature has created a viral loop of organic growth.
