Nomad

Describe your life, not a destination. Nomad uses Gemini to reason about constraints and decide the best trip for you.

Inspiration

Most travel platforms force users to start with destinations and dates. In reality, people usually start with constraints: limited time, budget, family needs, mobility, and uncertainty about where to go.

Nomad was inspired by this mismatch. I wanted to flip the model and ask:

What if an AI could reason from intent instead of filtering destinations?

What Nomad Does

Nomad is an intent-based travel decision engine powered by the Gemini API.

Instead of choosing a city and dates, users describe:

  • Time availability
  • Budget limits
  • Who they’re traveling with
  • Preferences and constraints

Gemini then reasons about:

  • Where to go
  • When to travel
  • Why certain options fit better
  • What tradeoffs the user is making

How I Built It

Nomad is built as a lightweight web app using:

  • Streamlit for the UI
  • Google Gemini API for reasoning and content generation

The user provides a natural language description of their travel intent. This input is sent directly to Gemini with a carefully designed instruction that emphasizes constraint-driven reasoning over keyword matching.

Gemini returns:

  • Identified constraints
  • A reasoning section
  • Ranked destination recommendations
  • Risks and tradeoffs

Challenges

  • Designing prompts that encourage reasoning, not just listing destinations
  • Preventing generic travel advice
  • Structuring Gemini output so it feels like a decision engine, not a chatbot

What I Learned

  • Gemini excels at multi-constraint reasoning when the prompt is framed correctly
  • Clear intent modeling is more powerful than traditional search filters
  • AI products feel stronger when they decide with the user, not just suggest options

What’s Next

Future versions of Nomad could:

  • Support visa constraints
  • Optimize for carbon footprint
  • Compare tradeoffs visually
  • Personalize recommendations over time

Nomad demonstrates how Gemini can power decision-making, not just answers.
