Microsoft Quietly Used Generative AI in a Surface Ad

Microsoft has revealed that it used generative AI to help create a minute-long advertisement for its Surface Pro and Surface Laptop — but the surprising part is that the ad has been live for nearly three months without anyone realizing it.

The ad first went up on YouTube on January 30th. While it isn’t fully AI-generated, Microsoft confirmed in a recent Design blog post that AI played a significant role. Senior design communications manager Jay Tan explained that while some AI-generated “hallucinations” needed to be corrected, the final product blends AI output with real footage.

Tan detailed the creative process: shots involving detailed movement — like closeups of hands typing — were filmed traditionally, while quick cuts and simpler visuals were perfect opportunities for generative AI to step in.

Microsoft didn’t specify exactly which scenes were created with AI, but Tan outlined the workflow. AI tools helped generate the initial script, storyboards, and a pitch deck. The team then used text prompts, based on written ideas and sample images, to guide image generators. Those visuals were edited to fix errors before being fed into video generators like Hailuo and Kling — the only specific AI tools mentioned.

Creative director Cisco McCarthy described the iterative process as grueling: "We probably went through thousands of different prompts, chiseling away at the output little by little until we got what we wanted." Despite the effort involved, visual designer Brian Townsend estimated that using AI still cut time and costs by about 90%.

The project reflects comments from Microsoft’s design chief Jon Friedman, who recently told The Verge's Tom Warren that AI would enhance creative work rather than replace it, shifting the focus to "how do you edit?"

Even though the video has been public for months, few viewers noticed anything unusual. As of now, the YouTube ad has around 40,000 views, and none of the top comments mention AI involvement.

Knowing what to look for, you might now spot clues — like oddly rendered meeting notes or an oversized Mason jar — but for most viewers, the AI elements slipped by unnoticed. The rapid editing style helped conceal flaws, showing just how seamless AI-generated content can be when used skillfully.
