What it does
This bill sets up a one-year test at NIST. The test studies how AI companies tell people when they use AI. It also studies how companies tell people when AI made or changed content. NIST will write guidelines based on what it learns. NIST must report findings to Congress within 180 days.
Who it affects
People who use AI systems gain information about when they interact with AI. AI companies take part in the voluntary test.
One thing to notice
Companies choose whether to follow the guidelines. The bill does not say what happens if companies do not follow them.
