From digital twins to virtual influencers, here’s how brands are testing synthetic media and where the ethical lines are being drawn in the era of AI-generated talent.
Virtual presenters, AI-generated spokespeople, hyper-realistic avatars that never break script. It sounds like science fiction, but in 2025, synthetic media has officially entered the marketing mainstream.
Brands aren’t just turning to video avatars for localization, they’re training custom AI agents to serve as virtual customer service reps, live content presenters and even shopping assistants. Powered by platforms such as Soul Machines, Meta AI Studio and Synthesia’s personalized video engine, these agents combine natural language, lifelike visuals and brand-trained tone to deliver always-on performance at scale.

Following Klarna’s test of an AI shopping assistant powered by OpenAI that does the equivalent work of 700 full-time agents, other brands have followed suit, putting synthetic talent to work in very different but equally strategic ways.
Unveiled at VivaTech 2025, L’Oréal announced an expanded collaboration with Nvidia to supercharge its AI ecosystem, spanning everything from 3D product rendering to the launch of Noli, a first-of-its-kind AI-powered beauty marketplace. Through Creaitech, L’Oréal is scaling its use of generative AI and digital twins to create hyper-personalized, on-brand content across e-commerce, social and influencer channels – streamlining production and boosting engagement.
Meanwhile, H&M is pioneering the use of AI-generated ‘model clones,’ creating digital versions of 30 real-life models for campaign and social use. Each clone is watermarked and fully licensed, demonstrating how brands can responsibly scale synthetic content while respecting talent rights.
Both brands signal a broader shift: AI avatars and agents are no longer novelty acts, they’re being built into the brand system itself, trained on tone of voice, product data and usage intent.
These are just a few examples of how brands are now deploying synthetic reps across their e-commerce ecosystems – not just to front explainer content, but to interact in real-time with shoppers, pulling from product data, historical interactions and brand voice guidelines.
Next steps for Drummies
The appeal is obvious: scale, speed and localization – all without hiring or rebooking talent. But the rise of synthetic humans also raises some big questions. Are consumers comfortable with AI clones fronting their favourite brands? Do they need to know when a presenter isn’t real? And what happens when these avatars become indistinguishable from real humans?
Increasingly, transparency is non-negotiable. Consumers want to know when content is synthetic and regulators are starting to weigh in. Some brands have learned this the hard way, facing backlash for failing to disclose AI-generated imagery in ad campaigns.
And the industry is moving past the ‘real-but-weird’ aesthetic. Brands are opting for avatars that are clearly synthetic yet emotionally engaging, avoiding uncanny valley territory and leaning into stylized, branded personas that are recognizably AI-powered – but unmistakably on-message.
For marketers, the benefits are clear. Synthetic talent offers speed and scale, allowing content to be updated instantly in any language, tone or format. In some cases, AI presenters are outperforming live talent on key metrics including attention and recall, particularly in explainer content or localized training material. And with production costs slashed, synthetic media can deliver serious savings, especially for brands creating content at volume.
But here’s the top tip for Drummies: don’t rush to replace your human talent just yet. Instead, use AI avatars to augment your strategy, testing them in lower-risk areas like onboarding, FAQs or internal comms. And above all, be transparent. If content is AI-generated, say so, because trust, once lost, is hard to regenerate.
