Create Hyper-Real AI UGC Ads with Nano Banana, ArcAds & ChatGPT

AT Vidjet, we’re big fans of Andrew Yu's YouTube channel — it’s a must-watch for all the e-commerce related innovations! In this guide I’ll break down Andrew’s step-by-step workflow for creating insanely realistic AI UGC ads using Google’s Nano Banana image generator, ArcAds, ChatGPT and simple editing tools like CapCut. If you want to launch scalable, low-cost AI UGC that converts, this article covers the exact process, creative use cases, and where to place these videos (including product pages)

Why AI UGC is a game changer

AI UGC ads mimic authentic user-generated content — the kind of short, relatable clips shoppers trust most. Andrew emphasizes that every pixel, actor and script in his demos was AI-generated: the actor, the lines, the props and even the podcast set. That means you can produce dozens of on-brand ads for a fraction of the cost and time of hiring real creators.

‍

Step-by-step workflow (exact process)

‍

1) Pick your use case and inspiration

Andrew demonstrates three use cases: a travel hair-brush demo, fashion/leggings try-on, and a podcast-style supplement endorsement. Start by watching real UGC that converts and note tone, hook lines and pacing.

‍

2) Create your AI actor in ArcAds (Nano Banana)

‍

3) Write and refine scripts with ChatGPT

Drop your video transcript or notes into ChatGPT and ask it to rewrite or generate multiple short UGC scripts (10–25 seconds each). Andrew picks lines from the rewrite instead of copying everything verbatim — this gives more natural cadence for the AI actor.

4) Upload scripts to ArcAds and generate clips

‍

5) Assemble and polish in CapCut

Download each generated clip, add quick cuts, B-roll and captions in CapCut. Andrew pieces clips together into a short, high-converting creative with a clear CTA at the end.

‍

Three high-impact use cases

1) Product demo / travel essential

A short hook (“total hotel pillow hair disaster”) → product reveal → transformation B-roll → CTA. Relatability drives trust.

2) Fashion try-on

Use AI to outfit a model in your product (leggings, dress, sweater). The model doesn’t have to exist — you can change poses, camera pans, and product color to match ad variations.

‍

3) Podcast-style endorsements

Create an authoritative feel by placing an AI actor in a podcast set recommending your product. Microphone + conversational tone = perceived credibility.

‍

Reuse: place AI UGC on product pages

One powerful tip Andrew mentions is reusing short AI-generated videos on your product detail pages. Embed short-video widgets on your theme so every PDP can show authentic-style UGC without extra filming. Studies and merchant reports show AI-generated videos on-site can lead to +38% conversion rate and 3X the average time spent on PDPs — a huge lift in on-site engagement and conversions.

Practical tips & ethical reminders

Final results & expectations

Andrew’s demo shows fully AI-generated ads that are hard to distinguish from real creators. With the right prompts and editing, you can produce ad sets quickly and scale creative testing at low cost. Combine ArcAds (Nano Banana), ChatGPT for scripting and CapCut for assembly to replicate the process.
