How to Create an AI Influencer Using SlideStorm

You want to run UGC-style ads for your app, but you don't have a creator to film them. Hiring one is expensive. Being the face yourself feels weird. And stock footage looks like, well, stock footage.

SlideStorm now lets you create AI influencers — realistic, AI-generated personas that you own and control. You can generate portrait images, create short hook videos of them reacting and emoting, and combine those hooks with demo footage of your app to produce polished UGC-style ad content.

No camera. No talent fees. No scheduling headaches.

Let's walk through the entire process.

What Is an AI Influencer?

An AI influencer is a computer-generated character with a consistent face and appearance. Think of it as a virtual spokesperson for your app. Unlike stock photos or random AI images, SlideStorm's influencer system generates a consistent character that you can reuse across multiple videos, building recognition with your audience over time.

This is particularly powerful for app advertising. The UGC ad format — where a person reacts to or talks about an app, followed by a screen recording of the app in action — is one of the most effective paid ad formats on TikTok and Instagram right now. The problem is sourcing that person. An AI influencer solves that.

Step 1: Create Your Influencer

Head to the AI Influencers section in your SlideStorm dashboard. Click Create Influencer and you'll see a simple form with three options:

• Name — Give your influencer a name. This is just for your own organization, it won't appear in any content.
• Gender — Choose male or female.
• Hair Color — Pick from blonde, brunette, or redhead.

That's it. Hit Generate Influencer and SlideStorm's AI will create a high-quality portrait image of your character. The generation takes a moment — you'll see a loading spinner, and the page will automatically update when the portrait is ready.

Each influencer costs 1 credit to generate.

A Note on Consistency

The key advantage of the influencer system is consistency. Once your influencer is generated, their face stays the same across every hook video you create with them. This means your audience starts to recognize "the person" in your ads, which builds trust and familiarity even though they're entirely AI-generated.

Step 2: Generate Hook Videos

Once your influencer's portrait is ready, click into their profile and you'll find the Generate Hook Video section. This is where it gets interesting.

You write a simple text prompt describing the emotion, expression, or action you want. For example:

• "Looking shocked and excited, eyes wide, mouth open"
• "Nodding slowly with a knowing smile"
• "Laughing and pointing at the camera"
• "Raising eyebrows in disbelief"

SlideStorm turns your prompt into a short video clip of your influencer performing that action. The videos are generated in portrait orientation (9:16), perfect for TikTok and Instagram Reels ads.

Hook video generation costs 30 credits per video.

What Makes a Good Hook Video?

The best hook videos trigger an emotional response in the viewer within the first second. Think about what makes you stop scrolling:

• Surprise — Wide eyes, dropped jaw, the "wait, what?" face. This works brilliantly for "you need to see this app" style ads.
• Excitement — Big smile, nodding enthusiastically. Perfect for "this app changed everything" messaging.
• Skepticism — Raised eyebrow, slight head tilt. Great for "I didn't believe it until I tried it" angles.
• Urgency — Serious expression, leaning toward camera. Works well for "stop scrolling, you need this" openers.

You can generate as many hook videos as you want for each influencer. Experiment with different prompts until you find the reactions that resonate with your target audience.

Step 3: Create a Hook + Demo Video

Here's where everything comes together. Once you have a hook video you like, click the Use in Hook + Demo button that appears on each generated video. This takes you to the Hook + Demo creator, a three-step process:

Pick your hook video

Your AI influencer's hook videos appear alongside any stock hook videos. Select the one you want to use as the opening of your ad.

Add a caption

Write the text that overlays the hook video. This is the "I can't believe I only just learned about this app..." or "This app is literally free and nobody talks about it" type of copy. You get a live preview showing exactly how the caption will look over your hook video.

Select your demo video

Upload a screen recording of your app in action, or pick from one you've already uploaded. This is the payoff — the viewer saw the hook, now they see what the person was reacting to.

SlideStorm stitches the hook and demo together into a single, polished video. The final result costs 3 credits to create.

The Result: A UGC-Style Ad Without the UGC

What you end up with is exactly the kind of content that performs well in paid TikTok and Instagram ad campaigns: a person reacting to something with a captioned hook, followed by a demo of the product. It looks like organic user-generated content, but you produced it entirely within SlideStorm.

No coordinating with creators. No waiting for deliverables. No re-shoots because the lighting was wrong. You control the entire pipeline.

Managing Your Influencers

You can create up to 20 influencers per account. Each one maintains its own library of hook videos, so you could run ads for multiple apps or test different personas for the same product.

From the influencers index page, you can:

• View any influencer and their generated hook videos
• Delete an influencer when you no longer need them (this also removes their hook videos)
• Create new influencers as your ad strategy evolves

Tips for Getting the Most Out of AI Influencers

Match the influencer to your audience

A fitness app might want an energetic, athletic-looking influencer. A productivity app might want someone who looks polished and professional. Think about who your target users would trust.

Build a library of reactions

Don't generate one hook video and call it done. Create a range of emotions and expressions. Different ad angles call for different hooks, and having a library ready means you can produce new ad creatives fast when you need to test variations.

Write hooks that create curiosity gaps

The caption overlay is just as important as the facial expression. The best hooks make the viewer feel like they have to see what comes next. "Wait, this app is free?" works better than "Check out this cool app" because it creates a question the viewer wants answered.

Test multiple combinations

The beauty of this system is speed. You can mix and match different hook videos, different captions, and different demo recordings to produce dozens of ad variations quickly. Run them all, kill the ones that don't work, and scale the ones that do.

Keep demos short and punchy

Your demo video should show the most impressive or useful part of your app in action. Don't try to do a full walkthrough. Show the "wow" moment — the thing that makes someone download. Fifteen to thirty seconds is plenty.

The Bigger Picture

AI influencers aren't about tricking anyone. They're a practical tool for app developers and marketers who need UGC-style ad content at scale without the overhead of traditional creator partnerships. Used well, they let you iterate on ad creatives faster, test more variations, and find winning combinations without burning through your budget on talent and production.

The apps winning on paid social right now are the ones testing aggressively. If "I can't find a creator" or "UGC is too expensive" has been your blocker, that excuse just disappeared.
