What is XKeyscore?

XKeyscore is like having a super-cool detective who can read almost all the messages and websites people visit, but they do it without you knowing.

Imagine you have a big toy box full of different toys. Each toy represents a message, a website, or something else that someone uses online. Now imagine there's a robot that can look inside every single toy in the box, see what’s inside, and remember everything it sees, all day long, every day. That robot is kind of like XKeyscore.

Think of XKeyscore as a helper for spies or detectives who want to know what people are doing online. When you use your phone or computer, the internet helps you connect to websites and send messages. XKeyscore can watch that connection, it’s like having a little spy sitting on the line between your device and the internet.

It doesn’t just watch one person, it watches millions of people all at once. It’s like being able to read what every kid in your school is writing or drawing, without them knowing you're watching.

XKeyscore can remember everything it sees and even search through old messages later, like how you might look back at a diary from years ago. It helps detectives find clues about people’s online habits, all from behind the scenes, hidden from view.
