User-generated content has become one of the most powerful forces in modern advertising. Consumers trust content that feels real, relatable, and human far more than polished brand commercials. According to a 2024 Nielsen study, ads that resemble real user content can drive up to 38 percent higher click-through rates compared to traditional brand creatives. On platforms like TikTok and Instagram, this gap is even more pronounced.
The challenge for many brands is that influencer-led UGC is expensive, slow, and difficult to scale. Coordinating creators, approving content, and refreshing ads regularly can strain both budgets and timelines. This is why more e-commerce and performance marketing teams are turning to platforms that generate UGC-style ads without relying on influencers.
These tools use AI to replicate the look and feel of authentic user content. They allow brands to create testimonial-style videos, product demos, and social-first ads quickly and consistently. Below are five platforms that marketers use to generate UGC-style ads without influencers, each offering a different approach to authenticity and scale.
1. Heyoz
Heyoz is built for e-commerce and performance marketers who want ads that blend naturally into social feeds. Instead of producing high-polish commercials, it focuses on UGC-style formats that consistently convert, such as short-form videos, carousels, and product-focused visuals designed for platforms like TikTok and Instagram.
The platform allows teams to turn product images or product URLs into ads that look like real user content. This matters because TikTok reports that ads designed to feel native generate 63 percent higher engagement than traditional polished ads. Meta platform data supports this trend as well, with UGC-style creatives delivering stronger retention and lower cost per click.
A key strength of Heyoz is speed. Performance teams often use UGC hook workflows in Heyoz to produce multiple ad variations quickly. This makes it easier to test hooks, visuals, and formats before ad fatigue sets in. According to Meta, creative fatigue can begin within 7 to 10 days for high-spend campaigns, making rapid refresh cycles critical.
Heyoz is especially useful for brands that want consistent output without managing creators or filming new content every week. It fits naturally into paid social workflows where testing and iteration matter more than production complexity.
2. HeyGen
HeyGen is known for its realistic AI avatars that can deliver scripted messages in a conversational tone. While it is often used for explainers and internal videos, many brands now use it to create UGC-style testimonial ads without putting real people on camera.
The platform allows marketers to choose human-like avatars, customize scripts, and generate videos that feel personal and direct. This is useful for brands that want spokesperson-style ads without hiring actors or influencers. According to Wyzowl’s video marketing report, testimonial-style videos increase purchase confidence for 79 percent of consumers.
HeyGen works well for ads that rely on clear messaging, such as product benefits, comparisons, or problem-solution narratives. While the content is AI-generated, the delivery can feel natural enough for mid-funnel and retargeting campaigns.
3. Synthesia
Synthesia is widely adopted by businesses for training and educational content, but it is also used to generate UGC-style ads at scale. The platform enables brands to create videos with AI presenters who deliver scripts in a straightforward, human-like manner.
For advertisers, this is valuable when consistency matters. Synthesia allows teams to produce multiple versions of the same message with different languages, tones, or presenters. This aligns with data from Google, which shows that localized ads can improve engagement rates by over 20 percent in international campaigns.
While Synthesia videos are slightly more structured than organic creator content, they are effective for brands that want a clean, professional UGC look without relying on influencers.
4. DeepBrain AI
DeepBrain AI focuses on realistic digital humans that can deliver content with natural facial expressions and speech patterns. Brands use it to create product explanations, testimonial-style videos, and short ad creatives that mimic real user reviews.
This approach works well for categories where trust and clarity matter, such as fintech, education, and health-related products. A Think with Google study found that clear, human-led explanations increase ad recall by up to 30 percent.
DeepBrain AI is especially useful for brands that want more control over messaging while still maintaining a UGC-style presentation. It removes the unpredictability of creator partnerships while keeping the human element intact.
5. Rephrase.ai
Rephrase.ai allows brands to create personalized video messages using AI-generated people. While it is often used for one-to-one personalization, many marketers apply it to UGC-style ads by creating general testimonial or demo videos.
The strength of Rephrase.ai lies in personalization at scale. Brands can adapt the same video format across different audiences or product variations. According to Salesforce research, personalized marketing experiences can increase conversion rates by up to 26 percent.
For advertisers running segmented campaigns or account-based marketing, Rephrase.ai offers a way to deliver UGC-style messaging without relying on influencers or large production teams.
Conclusion
UGC-style ads have become one of the most effective ways to capture attention and build trust in crowded social feeds. However, relying on influencers is no longer the only way to achieve this look and feel. AI-powered platforms now allow brands to generate authentic, social-first ads quickly and consistently.
The platforms covered in this article approach UGC-style ads from different angles. Heyoz focuses on performance-driven, AI UGC workflows for paid social. HeyGen and Synthesia use AI presenters to deliver human-like messaging. DeepBrain AI emphasizes realism and trust, while Rephrase.ai brings personalization into the mix.
Choosing the right platform depends on your goals, budget, and creative strategy. As competition continues to grow across digital channels, brands that can produce UGC-style ads faster and test more variations will have a clear advantage. AI tools make that possible without the cost and complexity of influencer-driven campaigns.
