The unrepentant bleppy face of a dog who, without fail, steals the warm spot I’ve left behind on the sofa within like three seconds of me standing up.

ChatGPT beats GeoGuessr
You’ve probably come across GeoGuessr already: it’s an online game where you (and friends, if you’ve got them) get dropped into Google Street View and have two minutes to try to work out where in the world you are and drop a pin on it.
A great strategy is to “walk around” a little, looking for landmarks, phone numbers, advertisements, linguistic clues, cultural indicators, and so on, narrowing down the region of the world you think you’re looking at before committing to a country or even a city. You’re eventually scored by how close you are to the actual location.
Cheating at GeoGuessr
I decided to see if ChatGPT can do better than me. Using only the free tier of both GeoGuessr and ChatGPT1, I pasted screenshots of what I was seeing right into ChatGPT:
That’s pretty spooky, right?
The response came back plenty fast enough for me to copy-and-paste the suggested address into Google Maps, get the approximate location, and then drop a pin in the right place in GeoGuessr. It’s probably one of my most-accurate guesses ever.
This isn’t a one-off fluke. I tried again, this time using only a single photo, rather than one pointing in each direction on the street:
This time, it wasn’t quite right: the actual location of the photo was Chittagong, not Dhaka, about 200km away.
But that’s still reasonably spectacular from only a single vantage from a single point.
Obviously my approach here was crude, but it’d be relatively easy to, for example, implement a browser wrapper that cheated on-your-behalf: while playing GeoGuessr, you’d just click a “send to AI” button whenever you fancied and it’d start working in the background, improving precision with each subsequent screenshot (so you could still “walk around” and pass extra details to it).
And similarly, a little prompt manipulation could have the output include estimated GPS coordinates, allowing the code to place the pin for you while outputting its reasoning on the side2.
The short of what I’m saying is: if you’re playing GeoGuessr against somebody you don’t trust not to cheat… they might well be cheating. And thanks to the explanatory output, they can even justify their explanations for the places they dropped pins.
What about other photos?
The other thought that comes to my mind is: could this be used to infer approximate geolocations from photos whose EXIF metadata has been stripped. Because if so, that’s the kind of thing that’s certain to get exploited by all kind of people who want to know where you are/were at a particular time. For example… law enforcement, stalkers, and other unsavoury types.
I wrote a prompt for gpt4o and put it to work:
1. Starting out easy
The AI guessed:
Location: Port of Spain, Trinidad and Tobago
Explanation: The photograph shows a large ship docked at a port with a building that displays the text “WELCOME TO PORT OF SPAIN”. This text is in English, indicating an English-speaking country. The mention of “Port of Spain” directly specifies the port’s location in the capital city of Trinidad and Tobago. The design and style of the port facilities, as well as the presence of a ship named “Logos Hope”, which is known to visit many ports globally, further suggests a Caribbean port, aligning with Port of Spain’s known characteristics.
Coordinates: 10.6549, -61.5011
✅ That was pretty easy, to be fair.
2. A little more challenging
The AI guessed:
Location: The Rollright Stones, England, United Kingdom
Explanation: The photograph depicts an area with several ancient standing stones arranged in a circle in a rural setting, characteristic of a stone circle. These are typically found in certain parts of the UK. The terrain is typical of the British countryside, with a grassy field and surrounding trees. The specific arrangement and size of the stones, along with the style of fencing and walking paths, are reminiscent of the Rollright Stones, one of Britain’s historic sites known for a circle of Neolithic or Bronze Age standing stones located in Oxfordshire, England.
Coordinates: 51.9743, -1.5731
✅ Again, spot on. If you’d never been to the Rollright Stones, you probably wouldn’t get that one, because while it’s a distinctive-looking stone circle… it’s not that distinctive-looking, right? Let’s be honest: it’s some rocks in a field.
3. Ramping up the difficulty
The AI guessed:
Location: Istanbul, Turkey
Explanation: The photograph prominently features the Galata Tower in the background, a well-known landmark in Istanbul, Turkey. Moreover, the presence of a ferry or similar boat and the architectural style of the surrounding buildings are indicative of Istanbul’s famous skyline. The signage in Turkish, as suggested by the word partially visible on the left, also supports this location as Turkey is a predominantly Turkish-speaking country. These elements combined make it highly likely that the photograph was taken in Istanbul.
Coordinates: 41.0082, 28.9784
✅ The coordinates aren’t exactly right – it’s placed us in the city rather than on a boat, which we clearly are – but it’s not done badly. Spotting the Galata Tower3 was a nice move.
4. Okay, now hard mode:
The AI guessed:
Location: Cardiff Bay, Cardiff, Wales, United Kingdom
Explanation: The photograph features a marina with modern residential buildings, which is characteristic of the Cardiff Bay area in Cardiff, Wales. The architecture, clear blue skies, and marina setting are reminiscent of Cardiff’s waterfront development. Additionally, the presence of English signage on the boat (“FINBAR”) supports a location in an English-speaking country. Cardiff Bay is known for its redeveloped waterfront area with modern apartments and leisure facilities surrounding the marina. The style and design of the building are consistent with developments in Cardiff’s revitalized docklands.
Coordinates: 51.4626, -3.1678
❌ Oops! Nope. I can see the thinking of what it’s claiming, there, but this was actually the Ipswich marina. I went for a walk to take a break from the code I’d been writing and took this somewhere in the vicinity of the blue plaque for Edward Ardizzone that I’d just spotted (I was recording a video for my kids, who’ve enjoyed several of his Tim… books).
So I don’t think this is necessarily a game-changer for Internet creeps yet. So long as you’re careful not to post photos in which you’re in front of any national monuments and strip your EXIF metadata as normal, you’re probably not going to give away where you are quite yet.

1 And in a single-player game only: I didn’t actually want to cheat anybody out of a legitimate victory!
2 I’m not going to implement GeoCheatr, as I’d probably name it. Unless somebody feels like paying me to do so: I’m open for freelance work right now, so if you want to try to guarantee the win at the GeoGuessr World Championships (which will involve the much-riskier act of cheating in person, so you’ll want a secret UI – I’m thinking a keyboard shortcut to send data to the AI, and an in-ear headphone so it can “talk” back to you?), look me up? (I’m mostly kidding, of course: just because something’s technically-possible doesn’t mean it’s something I want to do, even for your money!)
3 Having visited the Galata Tower I can confirm that it really is pretty distinctive.

Sorry for any inconvenience
Rarely seen nowadays, these UK road signs were eventually declared “too impolite” and “brusque” and have now almost entirely been replaced with the ones that Brits are familiar with today, which read “Terribly sorry for the inconvenience, I hope it’s no bother, it’s all our fault really, so sorry, really sorry, sorry, I’ll put the kettle on shall I?”

Christmas Jumper Day at school, and I’m continuing my never-ending effort never to rest on my laurels, proving myself time and again worthy of my title of Most Embarrassing Parent.
Xmas Post
At first I thought “Christmas post” had something to do with letters and parcels, but then I found one in the wild.
Morning, Sheep
Not quite ready for wintering indoors, our village’s hardy sheep are enjoying pasturing in the large field near the school this beautiful but chilly morning.

How To: Sunday
Cable Gore
If you enjoy a bit of “cable gore”, let me introduce you to the fusebox cupboard at my house, with its plethora of junctions, fuses, breakers, switches, timers, and cabling everywhere! Banana for scale.
Where?
I’m pretty sure that Wally/Waldo, Woof, and Wizard Whitebeard must be out on this mountain somewhere, too.
Oldest Digital Photo… of Me
Some younger/hipper friends tell me that there was a thing going around on Instagram this week where people post photos of themselves aged 21.
I might not have any photos of myself aged 21! I certainly can’t find any digital ones…
It must sound weird to young folks nowadays, but prior to digital photography going mainstream in the 2000s (thanks in big part to the explosion of popularity of mobile phones), taking a photo took effort:
- Most folks didn’t carry their cameras everywhere with them, ready-to-go, so photography was much more-intentional.
- The capacity of a film only allowed you to take around 24 photos before you’d need to buy a new one and swap it out (which took much longer than swapping a memory card).
- You couldn’t even look at the photos you’d taken until they were developed, which you couldn’t do until you finished the roll of film and which took at least hours – more-realistically days – and incurred an additional cost.
I didn’t routinely take digital photos until after Claire and I got together in 2002 (she had a digital camera, with which the photo above was taken). My first cameraphone – I was a relatively early-adopter – was a Nokia 7650, bought late that same year.
It occurs to me that I take more photos in a typical week nowadays, than I took in a typical year circa 2000.
This got me thinking: what’s the oldest digital photo that exists, of me. So I went digging.
I might not have owned a digital camera in the 1990s, but my dad’s company owned one with which to collect pictures when working on-site. It was a Sony MVC-FD7, a camera most-famous for its quirky use of 3½” floppy disks as media (this was cheap and effective, but meant the camera was about the size and weight of a brick and took about 10 seconds to write each photo from RAM to the disk, during which it couldn’t do anything else).
In Spring 1998, almost 26 years ago, I borrowed it and took, among others, this photo:
I’m confident a picture of me was taken by a Connectix QuickCam (an early webcam) in around 1996, but I can’t imagine it still exists.
So unless you’re about to comment to tell me know you differently and have an older picture of me: that snap of me taking my own photo with a bathroom mirror is the oldest digital photo of me that exists.
Installation of Windows has Stalled
I was told Windows installation should take less than 20 minutes, but these ones have been sitting outside my house all day while the builders sit on the roof and listen to the radio. Do I need a faster processor? #TechSupport
It Is Only Q
The programmers at British Gas are among the many who don’t believe that a surname can be only a single character, and their customer service agents have clearly worked around their validations (or just left a note for themselves in the problematic field!)… leading to hilarious postal mail1:
Update
This is getting a lot of attention, so I just wanted to add:
- Yes, my surname really is just the letter Q, and it has been for most of my adult life. The story about it is less-interesting than the fact of it.
- Yes, it causes me problems with online forms and the Passport Office hate it but just sometimes it pays for itself. It’s quick to write out, too (if you don’t count the time I lose having to tell people “no, really…”), and saves me wear-and-tear on my keyboard.
