AI trip planners are genuinely useful — for some things. Planning an accurate day on foot isn't one of them, and the reasons are specific and predictable. Here's where they break, and a free way to get a real route instead.
What AI is actually good at
Credit where it's due. A chatbot is a fantastic brainstorming partner. "What's this neighborhood known for?" "Give me a rough shape for three days in Lisbon." "Rewrite my list of places into a day plan." For ideas, framing, and a first sketch, it's faster than any guidebook.
The problem starts the moment you trust that sketch as a plan and start walking.
Where AI trip planners fall down
1. It invents places — and says them with total confidence
A language model predicts plausible-sounding text; it isn't reading from a verified database. So you get real-sounding restaurants that don't exist, addresses that are slightly off, and opening hours it simply made up. This is called hallucination, and in travel it isn't a minor bug: you build half a day around a place, walk twenty minutes to get there, and find a shuttered storefront. The more confident the chatbot sounds, the more places you have to quietly fact-check.
2. You get a wall of text, not a map
A walking day is a spatial problem — it's about where things are relative to each other. A chatbot hands you a numbered list. To find out whether that order makes any sense on the ground, you still have to drop every single pin into a map yourself.
3. It doesn't think about geography
AI tends to list places by fame or theme, not by location. So Day 1 sends you from the harbor to a temple across town and back to a market two streets from where you started — an hour of the day spent on backtracking instead of sights. A good walking plan keeps each day inside one area; a chatbot has no real sense of distance.
4. There's nothing to edit, share, or take with you
The answer is a one-shot blob of text. Want to swap two stops, move one to Day 2, share the plan with the person you're travelling with, or open it offline on the trip when your data drops out? You're back to copying text into another app and rebuilding it by hand.
5. It doesn't know what changed last week
Places close, hours shift, a street gets dug up. A model trained months ago has no idea — and won't tell you it doesn't know.
The honest comparison
| What you need on foot | AI chatbot (ChatGPT / Gemini / Claude) | A walking-route planner (CityWalk Plan) |
|---|---|---|
| Real, verified places | Often invents them | Hand-curated, with real coordinates |
| A map you can see | Text only | Day-by-day route on an interactive map |
| Sensible order | By fame, not by location | Grouped by neighborhood, less backtracking |
| Edit · share · export | Copy-paste by hand | Reorder, share a link, export offline |
| Effort to get one | Prompt, re-prompt, fact-check | Pick a city → done |
The lazy-but-accurate middle ground
This is the gap a catalog-based planner fills. Instead of generating an itinerary word by word, it assembles one from a hand-maintained list of real places. CityWalk Plan is built for exactly this: pick a city, the number of days, and a pace, and it returns a day-by-day walking route of real, verified spots — with real map coordinates, no AI-invented stops — grouped by neighborhood so you don't double back. You see it on a map, reorder it, share it, and export an offline copy for the trip. Free, no sign-up, no prompt-wrangling.
Call it the lazy way to plan a city walk. It just won't send you somewhere that closed two years ago.
Or — use both
If you like working inside a chat, you don't have to choose. CityWalk Plan is available as an MCP tool, so Claude or ChatGPT can call it and hand you a route built from the real catalog — the chatbot's ease, the planner's accuracy, in the same conversation. The AI does the talking; the catalog does the facts.
FAQ
Can ChatGPT plan a walking itinerary?
It can write one in seconds, but it often invents places, gets addresses or hours wrong, and gives you text instead of a map you can follow, reorder, or take offline. It's great for ideas — not for an accurate day on foot.
Why do AI trip planners recommend places that don't exist?
A language model generates plausible text from patterns, not facts from a verified database. So it confidently names a café, address, or opening time that's off, out of date, or made up. That's hallucination, and in travel it sends you to a shuttered storefront.
What's the best AI trip planner for a city walk?
For accuracy on foot, a catalog-based planner that uses real, mapped places beats a pure chatbot. CityWalk Plan is free, builds a day-by-day route from hand-verified places, groups them by neighborhood, and lets you edit, share, and export it offline.
Is there a free trip planner that doesn't make things up?
Yes. CityWalk Plan builds walking routes from a hand-maintained catalog of real places with verified coordinates — no AI-invented stops — and it's free with no sign-up. You can also have an AI assistant call it through MCP to get the same route inside a chat.
