I'll definitely take a look at it tomorrow.
I'm impressed that AI is that good.
Would be interesting to see how well it would fare on five photos from different years, using pictures that have never previously been uploaded anywhere.

They also got Worldle which was covered on hn - https://news.ycombinator.com/item?id=30367906

Make the logo clickable so it goes to the homepage
On the sharing stats page, add a link to start the game, e.g. if I send the link to someone to challenge my score, there needs to be an easy way to start the game.
Below my points, and how many avg years off, I got a dartboard, then "6", "3", emoji of a blind man walking, then "6".
As for some (hopefully constructive) feedback: I think the year selection slider could benefit from a few adjustments. If an image is from the distant past—say, pre-1950s—it might make more sense to use decade-based precision rather than individual years. For example, a black-and-white photo had me way off that caused me to lose 20 years of my life :). It would be helpful if such images were categorized more broadly, something like “191x”.
For mid-century images (roughly 1960–1990), a 5-year interval could strike a better balance. I came across one from that era and was six years off. And for more recent images, say post-2010, a one-year precision feels reasonable.
Of course, this suggestion mainly applies if we're deducing the year based on visual cues like clothing, hairstyles, and the environment. If the game is intended more as a quiz based on the text descriptions under the images, then it shifts more into trivia territory—and that’s a different type of challenge altogether.
Also, older photos are scored more generously, so being a few decades off won’t tank your score nearly as much as it would on a newer one.
Edit: I had seen the photo in the subway before, or something very similar. It's an interesting decision to use photos from big events that people might recognize. (Not inherently bad IMO, just not what I would have intuitively chosen)
Do you think it's more satisfying to guess based on clues like tech, clothing, and photo quality, or when you recognize the historical event or era (assuming it’s something a little less recognizable than that subway photo)?
Probably didn't help that I'm not American so the cultural references aren't there.
Might have gotten lucky but zooming in on clothing got me to 1.8 years off on average (top 2%).
> obviously towards the end of disco
What is the end of disco?
More seriously I often wonder how this works in the brain when there is no obvious historical clue. Is it akin to guessing a numerical quantity (like when seeing a crowd) ?
Same can't really said about someone from 1955 and 1975, 1980 - 2000, etc.

If you don't think the younger generation dress crazily then fashion didn't change. Every previous generation thought the next generations clothes were crazy.

Discussed on HN a couple of years ago too: https://news.ycombinator.com/item?id=37203511
edit: found another game like OP in the linked thread https://www.chronophoto.app/game.html
One thing though, the url in the share text doesn't start with https:// so it doesn't turn into a clickable link when posted in some chat clients.
Great game though, really good idea!
