It's a real video with a false caption. Will it catch that?

Not on its own: the checks judge whether the picture and sound were made or altered by AI, so a real clip with a false claim can come back “most likely real”. The fact-check lookup helps when fact-checkers have already covered the claim; otherwise, look for the original source and date.

Do I need an X account?
