Mark Zuckerberg, the boss of Facebook, showed off a cool new tool that can see what's happening in videos.
This tool, called Segment Anything 2, is like a super smart detective that can spot things like fish swimming in the ocean or people dancing.
It can even help scientists study animals in the wild or create digital copies of popular people on the internet!
This new tool is really amazing and will help us understand the world around us even better.
