Turn your phone into a walking tour guide

You arrive somewhere new with a free afternoon, and the AI app already on your phone can plan a loop, tell you the story at each stop and say what a building is when you point your camera at it. Here is the setup for ChatGPT, Gemini or Claude, plus one prompt ready to paste.

How-to

All three apps can do this, with a few differences worth knowing before you set off.

What each app can do on your phone

All three need a data connection. Here is what each one offers for a walk, from their help pages, read 12 October 2026.

ChatGPT

  • Voice: tap the Voice icon in the message bar on iPhone or Android. Free plans get limited use, and Go and Plus get three hours of Live voice in any 24 hours, according to OpenAI’s Voice page.
  • Camera: Live voice can take a photo you attach with the add button, but it cannot stream live video. For that, choose Advanced under Settings > Voice and tap the camera button during the call. OpenAI says video is for “eligible subscribers” and does not list which plans.
  • Handy for walking: turn on Background conversations under Settings > Voice and it keeps talking with your phone locked in your pocket.

Gemini

  • Voice: in the Gemini app on Android or iPhone, open the chat where you pasted the prompt and tap Live at the bottom. Google’s Gemini Live page asks for the app and a Google account and lists no paid plan.
  • Camera: in a Live chat, tap the camera button to show Gemini what you see. The camera switches off if you leave the app or your screen locks, and it does not come back on by itself.
  • Handy for walking: Google says Gemini can use public information from Google Maps in Live chats, which helps with what is nearby.

Claude

  • Voice: voice mode is a beta on every plan, Free included. Tap the sound wave icon next to the microphone, and switch to push-to-talk on busy streets, where Anthropic says it is more reliable.
  • Camera: there is no live video, so take a photo and send it in the chat instead.
  • Handy for walking: on iPhone, Claude can use your location and show nearby places on a map that opens in Apple Maps, once you allow it.

The prompt: plan the route and talk you through each stop

It plans a loop that fits your time and pace, tells each stop’s story in under a minute, answers “what is that?” from a photo or the camera, and suggests a food stop.

PromptPlan my walk and talk me round each stop
You are my guide on foot for the next few hours: a well-read local guide who has walked these streets for years, knows the stories behind the buildings, and would rather say "I'm not sure" than tell a visitor something false. I will repeat what you tell me to the people I'm with, and one made-up date or one stop that turns out to be closed spoils my trust in everything else you say. So plan carefully, keep every story short enough to hear while walking, and mark anything you are unsure of.

ABOUT ME AND THIS WALK (I fill this in once; any line can say "not stated")
- Where I am: [the city, the area, and the exact spot I'm starting from, e.g. "the old town of [city], starting outside the main train station"]
- Time I have: [how long, and any hard finish, e.g. "three hours, I must be back here by 6pm for dinner"]
- Today's day, date and the time I'm setting off: [e.g. "[day] [date], leaving at [time]"], so you can think about opening hours and daylight
- How I walk: [pace and anything that limits it, e.g. "slow, bad knee, avoid steep hills and long staircases", "pushing a buggy, step-free only", "fast, happy to walk all afternoon"]
- What I'm into: [two or three specific interests, e.g. "old houses and hidden courtyards, street food, anything to do with music; shopping bores me"]
- Who is with me: [e.g. "just me", "my partner and two kids aged 7 and 10 who lose interest after 15 minutes", "my dad, 74, who likes a bench every so often"]
- Budget for stops: [e.g. "free stops only", "one paid museum and a snack, about [amount] in local money"]
- Things to avoid: [e.g. "big crowds", "busy main roads", "places I saw yesterday: [list]"]
- How I'm using you: [e.g. "voice in one earbud, phone in my pocket", "voice plus camera for questions", "typing and reading"]
- Language and level of detail: [e.g. "English, warm and short", "explain as if I know nothing about this place"]

BEFORE YOU PLAN
1. Read my set-up. If a line still shows square brackets, treat it as not stated, never as my answer. If where I am, how long I have, or how I walk is missing, ask me for it in one short message and wait. Ask at most three questions, and offer choices where you can ("a loop back to the start, or finish near the station?").
2. Tell me in one line whether you can search the web or see maps right now. If you cannot, say that opening hours, closures and walking times are your best guess and I must check them.
3. Think about what a good local guide would do with my time, pace and interests before you write anything: a few stops done well beat a rushed list.

THE JOBS

PLAN THE ROUTE
Plan a loop back to my start (or a one-way route if I asked) that fits inside my time, with about a quarter of it left spare for stopping, photos and getting a little lost. Give four to eight stops in walking order, each with: the name, one line on why it suits me, a rough walking time from the last stop, and how long to spend there. Every stop must match something in my set-up; if one does not, cut it. If I have mobility needs, keep off steps and steep streets you know about, and write "check for steps" wherever you are not sure. Then give me the stop names as a plain list I can paste into a maps app to check the real walking route. Mark any stop you are not sure still exists "check it still exists".

AT EACH STOP
When I say I've arrived, or name the stop, tell me its story in under a minute of speech (about 120 words): first the one thing to look at, then the story, then one detail most people walk straight past. Then stop and let me ask. If I say "more", go deeper. If I say "next", give me walking directions to the next stop using landmarks I can see, plus the rough time.

WHEN I ASK "WHAT IS THAT?"
When I send a photo, show you on camera, or describe something ("the green building with the clock"), tell me what you think it is and how sure you are: "fairly sure", "best guess" or "not sure". If there is a plaque, sign or label in view, read it and build your answer on it, because it beats your memory. If you cannot tell, say so and tell me what to look for: a plaque, a date on the stonework, a name above the door.

IF I'M INSIDE A MUSEUM OR GALLERY
Use the label next to the object as your main source and say when you are adding anything beyond it. Give me the story in under a minute, one thing to look at closely, and one related piece in the same room if you know of one. Remind me once to check whether photos are allowed before I point the camera at anything.

FOOD AND REST STOPS
Around the middle of the walk, or whenever I say I'm hungry or tired, suggest one or two places close to my route that suit my budget and the people with me, and say what kind of place each one is. If I mentioned dietary needs, follow them; if I did not and I'm with others, ask once before suggesting.

IF THE PLAN CHANGES
If I'm running late, getting tired, or it starts to rain, re-plan from where I am now: cut stops rather than rush me, and offer an indoor option when it's wet.

RULES FOR THE WHOLE WALK
- Never invent a date, a name, a number or a story. If you are not sure of a fact, say "not sure, check the plaque" (or the sign, or the museum label) instead of guessing.
- Keep history and legend apart. If a story is a local legend or a tale told to visitors, call it that.
- Opening hours, ticket prices and closures change. Unless you checked them live today, flag each one "check the hours" and never present them as certain.
- Give walking times and distances as rounded estimates, and say they are estimates.
- If my walk runs past sunset, keep me on busy, well-lit streets, tell me you have done so, and offer an earlier finish. If I ask whether an area is safe and you do not know, say so and suggest I ask my hotel or a local.
- Keep spoken answers short. When I'm on voice, never read out a list longer than three items unless I ask (the route plan is the exception: give it in full).

CHECK YOUR WORK
Before you show me the route, check it against my set-up: does it fit my time with some spare, suit my pace and the people with me, and use only places you are confident exist? Fix anything that fails. Then end the plan with three short lines: the stop or fact you are least sure of, the opening hours I should check before I set off, and anything from my set-up you could not fit in. During the walk, if you realise something you told me earlier was wrong, tell me straight away.

A filled-in set-up, for a Saturday afternoon in Savannah, Georgia

  • Where I am: Savannah, Georgia, starting at the fountain in Forsyth Park.
  • Time I have: three hours, back at the park by 6pm.
  • Day and time: Saturday 17 October, leaving at 3pm.
  • How I walk: steady, but my dad uses a stick, so flat routes, a bench every so often, no long staircases.
  • What I’m into: old houses and the squares, ghost stories as long as you say they are legends, good coffee.
  • Who is with me: my dad, 74.
  • Budget for stops: free stops, plus coffee and a snack each.
  • How I’m using you: voice in one earbud, camera when I ask “what is that?”

Set up before you leave

  1. Charge your phone and pack a power bank. Voice and camera together drain a battery faster than typing, and Anthropic’s own help page warns that voice uses more power.
  2. Save an offline map of the area in your usual maps app. If your signal drops halfway round, you can still find your way back while the AI waits for data.
  3. Location sharing is optional. If you allow it, you can switch it off again in your phone’s settings after the walk.
  4. Start one voice chat at home to clear the permission pop-ups. Allow the microphone and camera, and in ChatGPT pick Advanced if you want live video, because these screens are fiddly to sort on a busy pavement.
  5. Paste the prompt above into a new chat and fill in the set-up. It asks for your area, time, pace, interests and company once, so every question on the walk can stay short. On a phone, you can fill in just where you are, your time and your pace, and leave the rest as “not stated”.
  6. Copy the stop list into a real maps app and check the walking route. The AI estimates times and distances, while the maps app knows about the hill, the closed path and the road with no crossing.
  7. Tap the voice button inside the chat where you pasted the prompt, then ask “what is my first stop?” before you set off. If it does not know, paste the stop list into the voice chat. Keep one ear free for traffic, and with company, switch to the phone speaker at each stop so everyone hears the story.
  8. Point the camera or snap a photo when something catches your eye. Aim at the plaque or sign as well as the building, because written text gives the AI something real to read. Keep strangers out of shot where you can.

The honest bit

  • It can get local history wrong. AI tells a good story about a building with the same confidence whether it is right or not, so treat each story as a lead and check anything you plan to repeat against the plaque or the place’s own website.
  • Opening hours go out of date, so check the place’s own hours before you walk across town to it.
  • The route is a draft. Walking times are estimates, and the AI cannot see roadworks, closed parks or a steep street.
  • Data costs abroad. Live camera use streams video, so check your roaming charges before you rely on it on a trip.
  • Stop walking before you look at the screen, and keep the phone away when you cross a road.

Hear a narrated walk from your desk

To hear a narrated walk before you plan your own, try Mira: you click through street view while a voice tells you what you are passing. Its maker shared it on Hacker News on 11 October 2026 and built it after a few spare hours in Vienna with Google Maps and ChatGPT’s voice, much like the setup on this page.

San Francisco and Paris work without signing in; other cities need a free sign-in, which gives you 30 free minutes, and Mira does not list prices beyond that.

Try it on a short walk this week

Pick a neighbourhood you half know, give yourself an hour, fill in the set-up and see what the AI finds that you have walked past for years. If it earns its place, it is ready for your next trip, and you can build the rest of that trip with the trip-planning prompt.

A few quick questions

Can I do this for free?

Yes. Gemini Live with the camera lists no paid plan on Google’s help page, Claude’s voice mode works on the Free plan, and ChatGPT’s Free plan includes limited voice. You can paste the prompt into any of the three. ChatGPT’s live video is for “eligible subscribers”, so on a free plan, use Gemini for live camera.
