What happens next
Claude will:
- Ask you just 5 questions to start — then build a rough Day 1 immediately so you can react to something real
- Refine progressively — one question at a time, each round deepening the plan based on your feedback
- Run a stress-test before finalising — jet lag, pacing, every person fed at every meal, single points of failure
- Show you its checklist at every transition — nothing moves forward until you confirm
- Build the app and walk you through publishing it for free
You can say at any point:
"Show me your checklist" — see exactly what Claude knows and what's missing
"What are you still missing?" — surface gaps before they become problems
"Check your list first" — if Claude tries to skip ahead
Claude will ask you questions one at a time — destination, dates, who's travelling, dietary needs, bookings — then build your itinerary for review, then build the app, then tell you exactly how to put it online. You don't need to know anything in advance.
Things to ask Claude
| When you want to… | Say this to Claude |
|---|---|
| Add another day to the trip | "Add a Day 6 to the app. Here's what we're doing that day: [describe your plans]" |
| Add a guide in another language | "Add a grandparent guide in Hindi. Keep it simple — just where to be and when, with one short note per activity." |
| Something isn't working right | "When I tap on Day 2 nothing happens. Can you fix it?" — Claude will ask for the file if needed. |
| Change how the app looks | "Change the colours to feel more like Japan — think cherry blossom pinks and deep indigo." |
| Add food and drink recommendations | "Add a food guide for Day 3 with the dishes we're planning to try, and flag anything that has nuts or dairy." |
| Update a booking or venue | "We changed our Day 3 dinner from Restaurant A to Restaurant B. Update everywhere it's mentioned." |
| Make a new icon for the app | "Make a home screen icon using a cherry blossom. Pink and white, simple and clean." |
| Make it work offline | "Make sure the app works without internet — pre-cache all pages so it works from the very first visit, even with no signal." |
