X, the website where you post messages, has a new button that lets you choose if your posts can be used to teach a special computer called Grok.
Grok is super smart and learns from all the things people write, but you can turn that off if you want.
The people who make sure everyone's data is safe are asking X some questions about this new button.
They want to make sure X is using your information in a way that's safe and fair for everyone.
