AI itinerary generator: what each tool checks, and how to use one well

An AI itinerary generator writes a trip plan from a few lines of input. That part is solved: every tool on this page will give you a tidy day-by-day plan in under a minute. What separates them is what happens to the facts in that plan, and most tools say surprisingly little about it.

So this guide compares what the makers actually claim, collects what the studies found when people checked AI plans, and shows the checks that catch the usual mistakes. It’s part of our guide to itineraries.

What does an AI itinerary generator do?

It takes your destination, dates, interests and pace, and asks a large language model to write a plan, usually morning, afternoon and evening for each day. Some tools stop there. Others then look things up: places on a map, live hotel or flight prices, opening hours, or the time between stops.

That second step is the one to care about. A language model writes what sounds right from what it has read, so it can recommend a café that closed last year or put a museum on its closing day with complete confidence. A tool that checks its plan against live data, and tells you what it checked, catches some of that before you do.

Which AI itinerary generators are there, and what do they check?

Here’s what each maker says its tool does, from their own pages and announcements, checked on 29 October 2026. “Not stated” means we couldn’t find the maker saying so, not that the feature is missing.

The pattern is clear enough. The big travel companies are adding AI to sell you the bookings they already sell. Very few tools say they check opening days for your dates or time the journeys between stops, which are exactly the two things that break most plans.

How often are AI itineraries wrong?

Often enough that you should assume at least one problem per plan. The studies we found, newest first:

The SEO Travel study is the only one that checked plans line by line, and it used an older model. But the 2026 surveys point the same way, and the failures in the news are the same kind. In 2025, two tourists in Peru set out for a “Sacred Canyon of Humantay” that an AI had described and that doesn’t exist, until a local guide stopped them. In January 2026, an AI-written tour company blog sent drivers in Tasmania looking for hot springs that had never been there.

For the longer version of this, with the 10-minute check, see can you trust an AI travel itinerary.

What should you type into an AI itinerary generator?

Your fixed times and your limits, as well as your interests. A generator can’t respect a 15:00 check-in it hasn’t been told about. This prompt works in any chat-based tool:

Plan [number] days in [city] from [weekday, date] for [who: two adults, or a family with children aged 4 and 8]. We land at [time] on day 1 and leave at [time] on the last day. Hotel check-in is [time], checkout [time], in [area]. We like [two or three interests]. Keep each day in one area, with no more than two main sights a day, lunch, and a break in the afternoon. For each sight, say if it needs a timed booking and whether it’s closed on any of our dates. Mark anything you’re not sure about.

Then push it with follow-ups:

• “Which of these places are closed on any of our dates?”
• “Move anything that needs a timed ticket to the morning.”
• “Make day 3 a slow day.”
• “Give me an indoor backup for each afternoon.”
• “What’s the walking time between each stop?”

Treat the answers to those follow-ups as claims to check, not facts. A model asked whether a museum is open will often say yes.

How do you check what an AI itinerary generator gives you?

Check every place exists, is open on that date at that time, and can be reached in the gap you’ve left. Those are the checks that catch most errors, and they don’t need an AI.

This is what Amicly’s checker does, in code, to every plan it writes and to any plan you paste into Check my itinerary:

When it can, Amicly fixes problems in code before you see the plan: it moves a whole day off a closing day, and reorders sights between meals when that saves at least a kilometre and a fifth of the distance. Anything it can’t check is labelled, and it never shows a confidence score. A checked plan still isn’t a booking, so confirm anything time-critical on the venue’s own site. How Amicly’s AI travel planner works explains each step and its limits.

When is an AI itinerary generator the right tool?

When you need a first draft for a place you don’t know, or a fresh order for a list you already have. It’s fast at grouping places by area and at suggesting what fits between two fixed points.

It’s the wrong tool for anything where a mistake costs money or strands you: entry rules, visa requirements, ferry and last-train times, or a booking you can’t change. For those, use the operator’s or the government’s own page. And if you’d rather build the plan by hand, how to make a travel itinerary takes about an evening, with checks built into each step.

Questions about AI itinerary generators

Is there a free AI itinerary generator? Several. Google’s Gemini app and AI Mode, Wonderplan, Tripadvisor Trips and Booking.com’s planner are free to use, and Amicly’s first plan is free with a free account. Free usually means the plan isn’t checked against your dates.

Can ChatGPT plan a trip? Yes, it writes a good first draft, and with the Expedia or Booking.com app it can show hotels and flights. Check opening days, journey times and every booking yourself, or paste the plan into a checker.

Are AI travel planners accurate? Not reliably on facts that change. In the one line-by-line study we found, 90% of 100 ChatGPT itineraries had at least one error.

Does Google have an AI trip planner? Yes. AI Mode in Google Search can build a trip plan in a side panel called Canvas, using Google’s flight and hotel data and Maps reviews, and the Gemini app plans trips too.

What’s the difference between an AI itinerary generator and an AI travel planner? Mostly the name. Some use “generator” for tools that only write the plan and “planner” for tools that also book or check, but the industry doesn’t use the words consistently.
