Artificial intelligence is supercharging the threat of election disinformation worldwide, making it easy for anyone with a smartphone and a devious imagination to create fake – but convincing – content aimed at fooling voters.

It marks a quantum leap from a few years ago, when creating phony photos, videos or audio clips required teams of people with time, technical skill and money. Now, using free and low-cost generative artificial intelligence services from companies like Google and OpenAI, anyone can create high-quality “deepfakes” with just a simple text prompt.

A wave of AI deepfakes tied to elections in Europe and Asia has coursed through social media for months, serving as a warning for more than 50 countries heading to the polls this year.
