This is killer. Love it! Are you planning to monetize it or keeping it as is?

The videos are all created with AI. It’s a pipeline of Flux (images), Kling (video), and mmaudio (audio). The videos aren’t always historically accurate to the last detail. They might incorporate elements of folklore or have details from popular beliefs about the way things looked rather than the latest academic research on how they looked.
I’m thinking a lot about how to make the game more interactive. One thing that makes Geoguessr so fun for me is that you can move infinitely and always find more details to help you pinpoint the location. I want Time Portal to have a similar quality. I have a few ideas to try soon that will hopefully make the game more interactive and infinite.

Edit: dang suggested we should add more about the link to our startup, so here's more if anyone's interested:
Originally, we were making an AI video creator tool with a focus on character consistency in long videos (https://news.ycombinator.com/item?id=39853474). A year ago, character consistency was a big problem and we developed a solution for it in AI videos. Now though, a lot of other AI video creator tools have come out, and 1) character consistency has been solved in other ways 2) the other tools just make better quality videos than ours.
So we decided to pivot from building video creator tools to building apps with AI video as the core format. When I say that we plan to sell apps like Time Portal, it's still pretty open ended. First, we just want to build an app/apps that people really like using for free and figure out the best way to monetize them later. Time Portal is not for sale right now. It's free to play on the web and there is a free app in the App Store.
