Virtual influencer for brands: how to create one with AI

A virtual influencer for brands is a digital character that talks, recommends products and appears in ad videos without being a real person. It can be a three-dimensional CGI character produced by an agency or a talking avatar generated by AI from a photo, with a synthesized voice and automatic lip sync. Brands adopt the format because it lets them produce dozens of creatives a week, with full control of the message, no fees to negotiate and no dependence on anyone's schedule.

What a virtual influencer is and why brands use one

The idea of a virtual influencer scaled up in Brazil with Lu from Magalu, created by Magazine Luiza in 2007, which reached more than 7.8 million followers on Instagram. The character speaks for the brand, promotes products and interacts with followers with a consistent personality: always available, always aligned with the company's values and with no risk of off-script behavior.

What changed in 2025 and 2026 is that creating a character like this became accessible to brands of any size. Generative AI cut the cost of producing videos with digital characters from tens of thousands of reais (in the Brazilian market) to monthly subscription levels. Today any e-commerce store or infoproduct creator can have a consistent face in their ads, without hiring an animation agency or a CGI production company.

Consumer interest points in this direction. According to Sprout Social, 37% of consumers in general say they are more interested in a brand that uses AI influencers. Among Gen Z, that number rises to 46%. The global virtual influencer market is expected to exceed US$8 billion in 2026, according to industry projections released early in the year.

The two types of virtual influencer

There are two main approaches to creating a brand's virtual influencer, and they have very different costs, production times and use cases.

CGI and 3D characters: fully animated characters, like Lu from Magalu or Shudu. They need a three-dimensional modeling team, frame-by-frame animation and specialized post-production. The creation cost is high and content production depends on a technical pipeline. It is the choice of large brands with an annual campaign budget dedicated to the character.

AI talking avatar: the platform uses a reference photo, generates the character's face, syncs the lips with TTS audio and delivers an MP4 video in minutes. It needs no animation, modeling or technical team. For ads at scale on Meta and TikTok, the talking avatar delivers commercial results equivalent to a far costlier CGI: a recognizable face, a voice that recommends the product and a 9:16 video ready for the ad manager.

The big practical difference is not visual quality: it is iteration speed. A performance campaign needs to renew creatives every 7 to 14 days to avoid audience saturation. With CGI, each renewal is a new production. With a talking avatar, it is writing a new script and generating in minutes.

Why the talking avatar converts in ads

The format works for the same reason UGC works: it looks like a recommendation from someone real, not a banner or a TV spot. The viewer sees a face, hears a voice and processes the message as a personal tip, not institutional advertising.

The difference between a talking avatar and a human creator in how the ad is perceived is smaller than you might think. What defines retention in the first 3 seconds is the quality of the verbal hook and the naturalness of the voice. Well-executed lip sync closes the loop: the character speaks convincingly and the viewer does not get stuck on "is this real?". What matters in the ad is the message, not the origin of the character.

For brands, this has an important practical implication: the virtual influencer does not replace the human creator in every context, but it fills a volume the human creator cannot deliver. A/B tests with hook variations, different argument angles for the same product, creatives for each item in a wide catalog: all of this becomes viable without multiplying the production budget.

How to create a virtual influencer for your brand with AvataReel

With AvataReel, the flow to get a virtual influencer into your ads has three steps.

Pick the influencer: the catalog has options with different profiles, age ranges and communication styles. You choose the one that best represents the product's audience. If you want an exclusive, proprietary character, uploading a photo creates an avatar only your brand uses.

Write the script: the script defines the influencer's personality in the campaign. Use your brand's voice: direct, conversational, with a hook in the first 5 seconds. AvataReel converts the text into TTS voice with conversational intonation, with no pause or breath markers in the final script. You can make the video in Portuguese, English or Spanish.

Generate the video: the platform processes the lip sync and delivers the HD 9:16 MP4. The file is ready for direct upload to Meta Ads Manager or TikTok Ads Manager, with no additional editing.

To use the same character across multiple campaigns, simply reuse the same influencer with different scripts. This face consistency builds brand recognition over time, even without building an organic profile on social networks.

How to write your virtual influencer's script

The script defines how convincing the character seems, the video length and the ad's retention rate. For a virtual influencer video in ad format, the most effective structure has four parts:

1. Hook (0 to 3s): a sentence that stops the scroll. It can start with the result ("This product changed how I sleep"), with a question ("Are you still paying a human creator for each ad?") or with a discovery ("This one I saw in my feed changed everything").
2. Context or problem (3 to 8s): creates identification with the viewer. The character talks about a situation the audience recognizes.
3. Product and benefit (8 to 20s): presents the item with specificity, without generic adjectives. Use concrete data when it exists: "yields 30% more", "delivers in 2 days", "lasts 3 times longer".
4. CTA (last 3 to 5s): clear and direct. "Click the link in bio", "It's tagged here", "Check it out before it sells out".

Virtual influencer vs. human creator: when to use each

The virtual influencer is not the right answer for every creative. For top-of-funnel branding campaigns where the authenticity of a human testimonial is the central differentiator, the real creator still has the edge. But for volume, speed, message control and continuous renewal, the AI talking avatar has a structural advantage.

Use cases where a virtual influencer makes the most sense

Stores with a wide catalog: when there are dozens of products and each needs a different creative, the virtual influencer lets you produce at scale without multiplying the cost by the number of SKUs. The same influencer appears for each product with an adjusted script.

Brands in the creative testing phase: before investing in a campaign with a human creator, testing hook and argument variations with a talking avatar costs a fraction of the price. The learning shows which angle converts before spending on human production.

Campaigns with weekly renewal: platforms like Meta Ads and TikTok ads saturate creatives quickly. Renewing with a virtual influencer every week is viable; with human creators at that pace, cost and logistics make the cadence unworkable.

Products with regulated messaging: categories like health, finance and beauty have strict rules on the claims allowed in ads. With the talking avatar, the brand controls every word of the script without negotiating content approval with an independent creator.

Where to start

The most direct entry point is to create a creative with a virtual influencer for your store's best-selling product, compare it with the current creative in a test campaign and measure CTR and conversion rate over 7 to 10 days.
