This AI Trick Is Replacing Influencers in 2025 (and It Works)

Are influencers already being replaced by AI? Here’s how I built viral UGC ads in 2025 without hiring a single human face.

You ever stare at a blank screen, thinking, How the heck am I supposed to make ads that don’t suck? Yeah, I’ve been there too. And honestly? The answer wasn’t what I expected.

It wasn’t hiring more creators. Or filming more B-roll. It was leaning into AI yep, fully AI-generated user-generated content (UGC). Sounds like a paradox, right? But that’s the wild reality of 2025. And if you play it smart, you can make scroll-stopping ads that look totally real… without ever picking up a camera.

Let me walk you through how I went from zero to viral using nothing but AI tools, a few smart prompts, and a bit of strategic chaos.

Why I Gave Up on Traditional UGC

Working with creators used to be fun. Until it wasn’t.

You know the drill: DM a bunch of micro-influencers, negotiate terms, ship them product, wait three weeks for a video that’s either late, off-brand, or totally unusable.

Meanwhile, the algorithm doesn’t care. You need fresh creative like, yesterday.

That’s when I stumbled onto AI UGC. I saw a video that felt just like a TikTok from a real person. Turns out… it wasn’t. It was a voice clone. A fake face. An AI-generated video that looked and sounded freakishly legit.

My brain broke a little. Then I dove in.

Step 1: Swipe Winning Ad Angles (Don’t Reinvent the Wheel)

Before writing anything, I always steal. Shamelessly.

Here’s what I mean: I head to the Meta Ad Library, search for brands in my niche, and pull angles, hooks, and headlines that are clearly crushing it. Then I dump them into a Notion doc like a chaotic digital mood board.

If I’m working with, say, a wellness brand (like the one I tested AI UGC with), I might find stuff like:

• “I haven’t felt this good in months—and I didn’t change my diet.”
• “This one weird routine fixed my sleep.”
• “No gym, no caffeine, just results.”

Catchy. Scroll-stopping. And totally reusable with a new spin.

Step 2: Write Scripts That Sound Like Real People

Here’s where most AI videos flop: the script sounds like it was written by, well, a robot.

To dodge that, I use Claude AI (though ChatGPT works fine too). I feed it my best angles and prompt it like this:

“Write a 25-second TikTok-style script for a wellness supplement that helps with stress. Make it feel like a casual recommendation from a friend, not a sales pitch.”

Then I tweak the output like a mad scientist.

I’ll add ‘um’s, pauses, even little slang words. Like:

“Okay, I’m not usually into supplements… but this one? Kinda changed my week. I take it in the morning, and I’m weirdly calm at work now. My inbox is still a dumpster fire, but hey I’m not spiraling.”

If it reads like something your friend would send you, you’re doing it right.

Step 3: Bring It to Life with AI Avatars (No Actors Needed)

Now comes the cool part. I load my script into Arcads.ai, a tool that lets you choose from dozens of AI avatars that look and act like real humans.

Want a 30-something guy who looks like he lives in a San Diego loft and drinks cold brew? They’ve got one. Need a Gen Z girl with big energy and a cute background plant? Yup.

You pick the vibe, the voice, and even tweak the delivery:

• Speed it up or slow it down
• Add more emotion
• Emphasize certain words

Then you hit ‘render,’ and boom you’ve got a video that looks like a creator filmed it in their bedroom, not a script fed to a machine.

Step 4: Launch a Whole Bunch of Variations Fast

Old way: film one ad, pray it works.

New way: make 15 versions in an hour.

I take the same script and swap out the AI avatar. Or take the same avatar and test different hooks. Or keep everything and just change the voice to Australian. Whatever.

Each combo becomes a new ad. Then I launch them in Facebook Ads Manager using Campaign Budget Optimization (CBO) so the algorithm can figure out what’s actually working.

Bonus tip: group your variations by theme like “funny,” “relatable,” “testimonial” so you can spot patterns.

Step 5: Kill the Losers, Scale the Winners

This is where it gets fun.

Once I’ve run my tests for a few days, I kill anything with a low click-through rate (CTR) or sky-high cost per acquisition (CPA). I keep only the best performers and make more variations based on what worked.

Did people love the laid-back tone? Cool let’s do five more like that. Did a certain avatar get better engagement? Make them your AI brand ambassador.

No drama. No wasted money. Just rapid feedback and faster scaling.

Real Talk: Does AI UGC Actually Work?

I get this question a lot.

Short answer? Yep.

Longer answer: it depends on how well you understand your audience and how willing you are to test aggressively. AI tools are powerful, but they’re still just tools. If your offer sucks or your angle’s boring, no avatar’s gonna save you.

But when you get it right? It’s pure magic. I’ve seen $40 CPAs drop to under $15. Videos that look like they were filmed in a dorm room absolutely crush professionally shot content.

So… if AI can help you make better ads, faster and cheaper than ever so what’s really stopping you?
