Why does the AI put closed museums and restaurants in my plan?

It answers plausibly rather than accurately. Museums stop admitting 30 to 60 minutes before closing, markets shut in the late afternoon, and many of the best local restaurants serve dinner only. The builder makes the prompt verify hours for the exact arrival slot.

How do I get the itinerary as a Word file instead of chat text?

The prompt already asks for it. If the model still answers with text, follow up with: put this in a Word document and attach the file. ChatGPT builds it with its interpreter, Claude through file creation, Gemini exports to a document.

How many stops fit in one Google Maps link?

Google's documentation allows up to nine waypoints, and only three when the link is opened in a mobile browser, inside a 2048-character limit. That is why a long day is split into segments of three rather than crammed into one link.

Yes, free and without registration — the prompt is assembled in your browser. You may need to pay for the AI model itself, depending on the plan you use.

Itinerary Prompt Builder

Pick the kind of trip, fill a few fields, copy the prompt. The checks that keep a plan alive on the street — opening hours for your exact slot, arithmetic that adds up, a loop instead of a zigzag, maps links that actually open — are added for you, and the builder shows what it added.

Where to paste it

The prompt assumes a model with web access that can build a file: ChatGPT, Claude, Gemini. Without search the model recalls opening hours from memory, and that is the single biggest reason plans collapse on the street. If the model answers with text instead of a file, ask in a follow-up: "put this in a Word document and attach the file".

Why the prompt is long

"Plan me a day in Prague" gives a pretty list that dies at the second stop: the market closed at 17:00, the restaurant only serves dinner, the museum stopped admitting an hour before closing, and the way back crosses the same street twice. The length here is not decoration — it is a list of checks, each one closing a specific failure.

Maps links that open as a route

The builder asks for links in machine format: https://www.google.com/maps/dir/?api=1&travelmode=walking&origin=LAT,LON&destination=LAT,LON&waypoints=LAT,LON%7CLAT,LON

travelmode takes walking, driving, transit, bicycling. A transit leg left as walking shows a nine-kilometre hike.
The pipe between waypoints is encoded as %7C.
Google's own documentation allows up to nine waypoints, and only three when the link is opened in a mobile browser, inside a 2048-character limit. That is why a long day gets split into segments of three.
Coordinates beat names: "Chelsea" exists in both London and New York.
