how to plan a trip with AI.

The best AI trip plans begin with who you are, not where you're going. Before you type a single destination, jot down the shape of your ideal day: how you like to eat (street food or slow tasting menus?), how much culture you actually enjoy (a single museum vs. a whole afternoon of them), your walking tolerance, budget bracket, and rhythm — early bird or slow starter. This taste profile is the single most important input an AI travel planner has. Romi uses yours on every plan so two people asking for "three days in Lisbon" get two completely different days.

A vague prompt gets a vague plan. A great AI travel-planner prompt names the city, dates, home base or accommodation, mobility (walking, transit, mixed), what you've already done in this city, if anything, and one or two non-negotiables ("a really good coffee morning", "no lines", "one nature moment per day"). Keep it in plain sentences — modern models read intent, not keywords. Then ask for the day structured by time blocks, with walking times between stops. That last part is what makes a plan usable on the ground.

A list of ten places is a to-do list; a good travel day is a rhythm — walk, eat, culture, rest, repeat. This is where a wrist-first watch face beats a phone. On roam o'clock the day is a ring of colored arcs: lime for walking, pink for eating, lilac for culture, creme for rest. You glance and see the whole shape of the day. You don't have to remember what's next — the dial does. That's how locals move through their own city — to a rhythm, not down a list.

AI models hallucinate less than they used to, but venues genuinely close, change hours, and move. Any AI trip planner worth using should ground its output in real, current data. Romi cross-checks names, hours, and status against live web search and Google Maps before handing you the plan. On your side: skim opening hours for anything time-sensitive (that one restaurant that closes on Tuesdays), and book anything that needs a reservation before the trip. A brilliant plan full of places you can't get into is just a good story.

The single biggest failure of phone-based travel planners is that you have to open them. You end up head-down on a busy street, tapping into Google Maps, tapping back into notes, missing the city you came to see. A watch face fixes that: current stop, next stop, and when to leave, all in one glance. Even if you don't have a Wear OS watch, the same principle applies. Pin your plan to the lock screen. Widget-ify it. The goal is to look up more than down.

The best AI plans are drafts, not scripts. The weather turns, a museum has a queue, a coffee spot pulls you in for two hours. The right tool lets you replan the remaining day in one tap — same taste profile, same city, new starting point. Manual edits should be cheap: swap a stop, move a block earlier, drop the museum entirely. If your trip planner treats every change like a rebuild, it's fighting you. A good one rolls with you.

Two minutes at the hotel with the day still fresh does more for your next trip than any pre-planning ritual. Rate the stops. What did you love, what was mid, what would you cross the city for again? Good travel AI learns from this — Romi factors your past ratings into future plans in the same city and, over time, into your taste profile wherever you go. Reviewing is also how you earn credits back in the app. Do it after every trip and the plans keep getting better.
