How tall do you think these men are? Women now using AI to catch men lying about being 6ft tall on dating apps - and here's how you can try it

ChatGPT has already been used to write essays, tell jokes and even write best man speeches. 

But it seems the helpful AI bot can even make sure people on dating apps aren't lying to you about their height.  

Women are screenshotting photos from dating app profiles, inserting them into ChatGPT and asking it to provide an estimate of how tall they are. 

Justine Moore, a venture capitalist in San Francisco, said the AI's estimates are accurate to within an inch – not just for men but for women too. 

So it may be a good tool to size up your romantic interest before you arrange to meet.

A tweet from Justine Moore, a venture capitalist in San Francisco, went viral when she posted her results from ChatGPT - from photos of both men and women

How to check your match isn't lying about his height

In her tweet, Moore said: 'Girls are using ChatGPT to see if men are lying about their height on dating apps. 

'Upload four pictures, it uses proportions and surroundings to estimate height. 

'I tested it on 10 friends and family members – all estimates were within 1 inch of their real height.' 

As long as you have a ChatGPT account, you can try out the nifty trick for yourself. 

Just take screenshots of your match from whatever dating app you use, whether it's Tinder, Bumble, Badoo or OKCupid.

If you only give it one photo to start with, ChatGPT may ask for more photos so it can make a more accurate assessment.

I tried it out by giving ChatGPT a photo of myself – but one photo wasn't enough and only after submitting a second photo did the AI give an estimation.

Only after submitting a second photo did the AI give an estimation - 'likely around 6 feet', which is a couple of inches off my actual height

So, how tall are the men in the photos?

A - 6ft 4 inches 

B - 6ft 1 inch 

C - 6ft 2 inches

It said: 'Based on proportions and typical height ranges, he seems to be relatively tall, likely around 6 feet (183 cm) or more.'

I'm about 6 feet 2 inches, so it wasn't a bad guess, although both photos were more or less full-body shots. 

ChatGPT struggles to give the best estimate when most of the person's body is not included in the photo.

It also needs distinctive features in the background, such as a car or street sign so it can put the body into proportion. 

Women especially are increasingly looking for ways to make sure they don't end up on a date with anyone shorter than their personal ideal. 

On dating apps such as Bumble and Badoo, people add personal details to their profile to increase chances of getting a perfect match – including their height. 

But men are becoming increasingly prone to add a few extra inches to their actual height to increase their chances of getting a date, according to analysis by OKCupid.

Some blokes are trying to make their height less obvious by making height ambiguous – deliberately opting for snaps of them sitting down, for example. 

One trick is standing on a crate and posing next to a car to boost relative height, with photos taken from below to make them look gigantic.

A fair height is generally a preferred trait; scientists think a taller man is perceived by a woman as someone who can protect them against danger or produce healthy offspring.

Studies have shown that women don't like to be taller than their man, so taller men are generally more desirable. 

Too busy to find love? Send a robot instead! 'AI dating concierge' could date hundreds of people for you, Bumble founder claims 

In the 2023 blockbuster, Robots, Shailene Woodley and Jack Whitehall star as singletons who send robot 'doubles' of themselves out on dates.

While this might sound far-fetched, it could soon become a reality.

That's according to Whitney Wolfe Herd, the founder of dating app, Bumble.

Speaking at the Bloomberg Tech Summit, Herd, 34, claimed that daters could soon use an 'AI dating concierge' to go out on hundreds of dates for them.

'If you want to get really out there, there is a world where your [AI] dating concierge could go and date for you with other dating concierge,' she said.
