I found this free tool that uses AI to create then and now images from your text instructions. GliF: Then and Now You can sign in for a free account using Google.
There are two text boxes - Then and Now. You enter your instructions and in a few seconds you get the image.
For example: I created the image above with:
Then: 19th century peasant immigrant family in Eastern European traditional outfits exiting boat on dock in front of Statue of Liberty. sepia tone
Now: Color image in the same location. Same dock structure and Statue of Liberty in alignment.
You'll see that the product lacks historical accuracy - but I think it could be a fun activity starter. Try it out and leave some comments or samples and let's see if we can figure out some good lesson ideas
Here's another one I made. AI "hallucinated" some strange bikes and an inaccurate White House with a rather low fence.
Then: 19th century cyclists - male and female riding historical bikes in historical attire in front of White House
Now: Color photo of White House from same perspective. Make sure then and now White House line up.
