The use of in Brazilian politics began in a shy, almost craft way. In 2022, it was still difficult to produce credible deepfakes. Nevertheless, false videos circulated in which the progressive field and audios attributed to.
In last year’s municipal elections, it arrived more strongly to the electoral dispute. An example is the campaign that they sexualized their image, marking the use of AI as an instrument of direct political attack. In May this year (2025), Buenos Aires was the scene of one of the most emblematic episodes so far: a video supporting Javier Milei candidate viralized the eve of the elections and helped Milei’s coalition win the Argentine capital for the first time.
So far, the political use of AI seemed experimental and punctual. This changed this week when, for the first time, which not only viralizing, but began to play narrative hegemony in the networks.
The most striking example is the video of “Boteco do Brasa”, published by the Instagram profile. The play simulates a bar conversation between rich and poor discussing who should pay the bill, alluding to the billionaire taxation proposal, banks and bets – called “BBB taxation”. The video has exceeded 20 million views, a colossal leap against the average party reels, which usually is around 50,000.
More than one exception, videos like “Boteco do Brasa” were the first explicit goal of the left in the field of AI political content. Then came other pieces: parodies with the mayor, luxury scenes, accessible language videos about tax justice. All with synthetic aesthetics, popular itineraries and massive range.
What seems to explain this new moment is, in part, technology. The recent launch of the, dramatically reduced the technical barrier to producing sophisticated AI videos. With subtitles, scenarios, voiceovers and automated editing, Veo facilitated the production of impacting videos and began to be explored as a tactical tool.
The structural advantage in the digital war has been on the right. With more engaged, more defined aesthetic networks and a well -organized content production machine, the right knew how to occupy the networks with efficiency and speed. The expected seemed to be that the advance of AI would amplify this advantage. But the effect may be the opposite.
By automating and radically cheapering content creation, AI models reduce the cost of entry into the narrative game. Now anyone with an idea and a prompt can create an impact audiovisual piece. “Boteco do Brasa” shows that a video generated by AI, with accessible aesthetics and aligned speech, can compete in volume and range.
This does not mean, however, that the game is tied. AI can balance the production dispute, but the field of distribution remains widely dominated by the right. Monitoring over 100,000 WhatsApp groups made by Palver shows that among the most viral messages about the government this week, 57% are unfavorable. The left digital offensive went viral on open platforms, but has not yet broken the barrier of everyday conversations – where the opposition remains majority.
What we can learn from this left victory is that the symbolic dispute is open. But winning this dispute requires consistency, frequency and network distribution capacity.
