## Problem

Planning an itinerary by hand is slow. The agency wanted a planner that turns a traveller’s preferences into a plan they can refine, without inventing places that do not exist.

## What we built

- An intake wizard for destination, number of days, interests, budget and pace, with AI-suggested destinations and filters
- An agentic planner that calls a place-search tool, up to six steps per plan, so activities come from real search results
- Itineraries streamed into the page as designed components (trip header, day headers, activity cards, notes) rather than a wall of text
- Chat to refine the plan, saved trips, and a read-only share page with a preview image
- Sign-in and a waitlist for early access

## Outcome

- Working end-to-end product, from intake to shareable trip page
