Make UGC-Style Ads With AI
The handheld, talking-to-camera ad format that outperforms studio creative — generated from a prompt instead of a creator brief.
AI UGC ads are video ads generated to look like organic creator content — handheld framing, casual selfie energy, a person talking to camera about a product — the format that consistently beats polished studio creative on TikTok and Reels. Video models with native audio (Veo 3.1, Sora 2) can now generate a convincing spokesperson take with lip-synced speech from a single prompt, and Seedance handles the product b-roll around it. ViralMint is a free, open-source desktop app that generates these clips on prepaid credits (from roughly $0.25 per clip), then captions, scores and exports them per platform. The UGC and product prompts below come from its free prompt libraries — each links to full settings.
How to make a UGC-style ad with AI
-
Script the hook first
UGC ads live or die on the first line. Steal a structure from the free viral hooks library ('I was today years old when…') and write 2-3 spoken lines max per clip.
-
Generate the talking take
Prompt Veo 3.1 with the persona, setting and the exact line in quotes — it generates the person AND the lip-synced speech. Keep takes to 8 seconds; authenticity reads better than polish here.
-
Cut in product b-roll and captions
Generate 2-3 product close-ups with Seedance, merge, and burn word-by-word captions in the viral preset. Export 9:16, 1:1 and 16:9 in one bundle for every ad placement.

Frequently asked questions
Can AI really do the talking-head part with voice?
Yes — Veo 3.1 generates a speaking person with synchronized lip movement and native audio from a text prompt that includes the spoken line in quotes. For a brand voice you control, generate the visuals and add narration with the Voice-over tool (including your own cloned voice).
Is AI-generated UGC allowed in ad platforms?
Generally yes, but platform policies require you not to mislead — many advertisers disclose AI-generated content in the ad. Check the current policy of the platform you're buying ads on; rules are evolving quickly.
What does a full UGC ad cost to generate?
A 20-30 second ad (one talking take + 2-3 b-roll clips + captions + music) typically lands between $2 and $5 on ViralMint credits — versus $100-300 for a single creator-sourced UGC video.
