🎬 Build AI Influencers & UGC Ads That Pay You - Zero Cost Technique

Are you ready to try the future of making content? Imagine you can create a virtual influencer or make professional ads without spending any money on actors, cameras, or a studio. This is not a dream anymore it's real, and this guide will show you exactly how to do it.

In this full guide, we will go through all the steps to create content using Google's newest AI technology. This guide is for you if you are starting a new business, a company founder who needs marketing content, or just curious about AI. It will give you everything you need to start.

Why This Is A Big Opportunity Right Now

Before we learn the technical steps, let's talk about the business chance here. We are not just making videos for fun - we are looking at two real ways to make money:

1. AI Influencer Business: You can create virtual people who get followers on Instagram and TikTok. Brands will pay these virtual influencers to show their products. Yes, people are already making real money with AI influencers. The best part is that you have full control over their image and content, and you don't have to worry about real-life problems.

2. Start a UGC Ad Agency: UGC means "User-Generated Content." These are ads that look like a normal person is holding a product and talking about it. People trust these ads more because they feel real. The need for these ads is huge. You can charge businesses money to create this type of content for them.

Between these two options, starting with UGC ads is a good idea for beginners. It is more practical, businesses need them right now, and it doesn't require as much constant creativity as building an influencer's personality. Businesses always need new ads, while building a community for an AI influencer takes more time and effort.

What You Need To Get Started

The main tool we will use is Google's video-making AI, which you can use through a tool called Google Flow. The best part is you can use it for free.

How To Get Free Access

Option 1: For Students (The Best Option)

1. Go to Google and search for "Gemini for Students".

   

2. Click the first link. This is Google's special offer for students.

3. Click "Get Offer" and confirm you are a student with your student email or ID card.

   

4. You will get one year of free access to Google's powerful AI tools, which you can use to make images and videos.

   

Note: This student offer is available until October 6, 2025. If you are not a student, maybe you know someone who is and can help you sign up.

Option 2: Limited Free Access for Everyone

1. Search for "Google Labs" on Google.

   

2. Click the first result to find Google's experimental AI tools.

3. Look for a tool named "Google Flow." This is Google's AI filmmaking tool that uses the newest video model.

   

4. Click "Create with Flow" to start.

   

5. You will get some free "credits" to try it out and make videos.

You will also need a tool to create a consistent image of your AI character. We will use Google AI Studio, where you can use the Gemini model to make pictures.

Step 1: Create Your AI Character

Before making videos, you need a face for your influencer or ad person that always looks the same. Google AI Studio is very good at keeping the face consistent in different pictures.

Making Your AI Person

1. Go to Google AI Studio.

   

2. Start a new chat and write a detailed instruction (this is called a "prompt") for your character. The more details you give, the better the result will be.

   

Example Prompt for Creating a Character:

Let's try to make a friendly male character who works at a coffee shop.

Create a portrait picture of a young Vietnamese man, around 24 years old, named Minh.
- Face: Friendly, has small dimples when he smiles, bright eyes that look enthusiastic.
- Hair: Black hair, cut in a short, neat layered style.
- Clothes: Wearing a dark brown apron over a plain white t-shirt.
- Background: He is standing behind the counter of a modern coffee shop with a lot of natural light. Behind him is a coffee machine and wooden shelves with small green plants.
- Action: He is smiling and looking directly at the camera, like he is welcoming a customer.
- Photo Style: Realistic, high-quality photo, with warm colors.

3. After the first picture is created and you are happy with it, save it.

   

4. To make more pictures in different situations, you must attach the picture you just made and change the prompt. This is the key to keeping the face the same.

Example Prompt to Change the Situation:

Use the male character from the attached image. Now, create a new image with these details:
- Background: He is sitting at a wooden table in the same coffee shop, but near a window.
- Action: He is holding a cup of latte art and looking happily out the window on a sunny day.
- Clothes: He has taken off the apron, and is just wearing the simple white t-shirt.
- Photo Style: Keep the same realistic photo style, with natural light and warm colors.

The secret here is to always attach the previous image so the AI understands and keeps the same facial features in all new pictures. Try to create a collection of 5-10 pictures of your character from different angles and in different places to use in your videos.

Step 2: Create Your First AI Influencer Video

Now that you have your character images, let's create the first video.

Plan Your Content

For an introduction video, you need a script. A script is the words the character will say. You can use an AI writing tool like ChatGPT or Gemini to help you.

Example Prompt to Create a Video Script:

I am creating an AI influencer named Minh, who is a coffee expert.
I have attached a picture of Minh for you to see.
Please help me write a detailed prompt for Google Flow to create Minh's first video for Instagram Reels.
The video should show Minh saying hello and introducing his channel, inviting people to explore the world of coffee with him.
The script should be short, fun, and interesting for about 8 seconds.

ChatGPT can give you a script and a video prompt. You will use the video prompt.

The Result:

Create a vertical 9:16 Instagram Reel video featuring Minh, a friendly young Vietnamese coffee expert (use the attached photo of Minh as visual reference for likeness). 

Scene: Minh stands in a cozy, modern coffee shop setting with warm lighting, wooden tables, and coffee equipment in the background (espresso machine, grinder, beans on shelves). Camera is medium-close (waist-up), centered on Minh, with smooth natural hand-held feel. 

Mood & Style: Energetic, fun, authentic influencer vibe. Bright, inviting atmosphere. Add light background café ambient sounds.

Action & Delivery: Minh waves to the camera, smiles, and speaks clearly and enthusiastically for about 8 seconds. Keep gestures natural and friendly. 

Script for Minh to say (short, fun, engaging):
"Hey everyone, I’m Minh! ☕ Welcome to my channel — your new stop for everything coffee. Let’s explore this amazing world together!"

Performance notes: 
- Speak with cheerful tone, slightly fast pacing to match Instagram Reel style. 
- Subtle hand gestures (wave at start, small coffee-pour motion with hands when saying 'coffee'). 
- End with a friendly smile, looking directly into the camera. 

Length: ~8 seconds.
Format: Vertical 1080×1920, optimized for Instagram Reels.

Making The Video

1. Go back to Google Labs and open Google Flow.

   

2. Click "New Project."

   

3. Choose "Frames to Video." Do not choose "Text to Video."

   

4. Upload the picture of your character Minh that you made in Step 1 (choose the best one where he is looking at the camera).

5. Change the aspect ratio to "Portrait" (9:16) for Instagram Reels or TikTok.

   

6. Paste the prompt you got from ChatGPT into the prompt box.

   Example prompt for Flow:

An animated video of Minh, the man from the image. He is standing behind the coffee counter, waves his hand enthusiastically at the camera and says "Hello everyone!". His mouth moves realistically as he speaks. The background shows subtle movements, like steam rising from the coffee machine. The lighting is warm and cinematic.

7. Click "Generate" and wait for it to finish.

   

What to Expect:

• It will take a few minutes to process.

• You will get a video clip that is about 8 seconds long.

• The quality will be surprisingly realistic.

• Sometimes the AI might add text that you don't want. You may need to cut it out using a simple video editor.

Step 3: Create UGC Ads

This is where the real business opportunity is. UGC (User-Generated Content) ads are videos where someone naturally talks about or shows a product.

Prepare Your Product/Business Images

For example, let's say you want to create an ad for a local skincare brand that sells sunscreen.

1. Find a high-quality picture of the sunscreen product. The best pictures have the product on a white or simple background.

   

2. Find a picture of a nice background, for example, a sunny beach or a green garden.

   

3. Download both pictures to use later.

Combine Your Character With The Product

Google Flow works best with a single image. So, we need to combine our AI character, the product, and the background into one picture.

1. Go back to Google AI Studio.

   

2. Upload all three pictures: your AI character, the sunscreen product, and the beach background.

   

3. Use this prompt:

I have given you 3 images: one is the male influencer, one is the sunscreen tube, and one is the beach background.
I want you to create a single image where the influencer is standing on the beach.
He is holding the sunscreen tube in his hand and smiling at the camera. He looks natural and happy.
Make sure the light in the picture looks like a sunny day at the beach.

4. Download the new combined image.

   

Create The UGC Ad Video

1. Go to ChatGPT and ask for a UGC ad script:

I want to use the same influencer to create a UGC ad for a sunscreen product.
I have attached the image of the influencer holding the product on a beach.
Give me a detailed prompt for Google Flow to create this UGC ad video.
In the video, he should talk about how great this product is for a beach day.

2. Take the prompt that is generated and delete any text-related parts or hashtags. When you ask for the prompt, you can add this note: "Only give me a prompt that describes the action and speaking for the video. Do not add hashtags or any other text."

   

3. Go to Google Flow and create a new project.

4. Choose "Frames to Video."

   

5. Upload the combined image (the man holding the sunscreen on the beach).

   

6. Paste the clean script.

   Example prompt for Flow:

Create a 12–15 second vertical video. The influencer is standing on a sunny beach, holding the sunscreen. He smiles and looks into the camera.

He says in a natural, friendly tone:
“Hey guys! I’m out here at the beach and this sunscreen has been a total lifesaver. It’s super light, not sticky, and keeps my skin protected all day. Honestly, it’s a must-have for any beach day.”

Actions during the video:

He first shows the sunscreen close to the camera.

He applies a little on his face and arms while talking.

He finishes by holding the product up proudly, with the ocean behind him.

7. Generate your UGC ad.

   

What Makes This Tool Powerful

Here is something amazing: sometimes, the AI is smart enough to add small details you didn't ask for. For example, it might automatically make the ocean waves move or make the character's hair move gently in the wind to make the video look more real. This shows how smart these tools are becoming at understanding the context.

Planning Your Video: An Important Step People Often Forget

Before you start making lots of videos, take a moment to plan. This will save you a lot of time and credits. Think of it like making a simple drawing before you paint a big picture.

1. Know your goal: What is this video for? To introduce your character? To sell a product? Or to tell a short story?

   

2. Write a simple script: Write down what the character will do or say in each scene. For example:

   

   • Scene 1 (0-5 seconds): Minh says hello and holds up a coffee bean.

   • Scene 2 (5-10 seconds): A close-up shot of the coffee bean. Minh talks about how good it smells.

   • Scene 3 (10-15 seconds): Minh is making coffee and smiling.

3. Prepare your starting images: For each scene in your plan, you need a starting image. Create these images in Google AI Studio before you start making the video. This helps keep everything looking the same and makes the video creation process smoother.

   

Planning ahead helps you avoid getting stuck and makes sure your video has a good story.

Business Opportunities And How To Make Money

AI Influencer Business Model

One way to make money is by creating your own AI influencer. The process begins when you start posting content regularly on platforms like Instagram and TikTok using the AI character you designed. By sharing interesting and consistent posts, you will slowly build a group of followers who enjoy your content. As your character gets more popular, brands will start to notice. They may contact you and offer to pay you to feature their products in your videos. Another way to earn is through affiliate marketing, where you get a small payment every time one of your followers buys a product using your special link.

The great thing about this business model is that it has the potential to make a lot of money, and you have complete creative freedom over your character and content. It's a business that you can grow very big over time. However, it's important to know that this path takes work. You need to create new content all the time to keep your audience interested. It also takes time and a lot of patience to build a large group of followers from the beginning.

UGC Ad Agency Model

A second, and often faster, way to make money is by starting your own UGC Ad Agency. In this model, you offer a service to create UGC-style ads for other businesses, such as local shops or online stores. Your main job is to create professional-looking videos that feel like genuine product reviews from a happy customer. You can charge businesses a price for each individual video you make, or you can offer them monthly packages that include a set number of videos. As you gain more experience, you can grow your business by working with many clients at the same time.

The biggest benefit of this model is that you can start making money much more quickly. There is a very high demand from businesses for this kind of authentic-looking ad, so it's often easier to get started compared to building an influencer from zero. The main challenge here is that you will need to actively find clients and be comfortable talking to them about their business needs and how you can help.

Example Prices (just a suggestion):

• Single UGC ad video: $50 - $200

• Monthly package (4-8 videos): $300 - $800

• Custom projects: Depends on how difficult the video is.

Tips For Success

Tips For Good Quality

• Always use high-resolution source images. A blurry picture will make a blurry video.

• Try different prompts to get better results. Sometimes changing just a few words can make a big difference.

• Use tools like Canva or Photoshop to remove any unwanted text or details from your source image before making the video.

• Keep your character looking the same. Don't suddenly change their hairstyle or eye color unless it's part of the story.

Tips For Good Content

• Look at successful UGC ads in the area you are interested in. See what they say and how they act.

• Keep the script natural and conversational, like how a friend would talk.

• Focus on the benefits of the product ("how does it help you?") not just the features ("what does it have?").

• Always include a clear call-to-action, like "Click the link in my bio!" or "Try it today!".

Technical Tips

• Save all your character images in one folder so you can find them easily.

• Write down the prompts that gave you good results in a document so you can use them again.

• Plan your scenes before you generate them to save your credits.

Limitations And Things To Think About

Current Limitations

• Hands and fingers: The AI still has trouble making perfect hands and fingers. Sometimes they can look strange.

• Complex movements: Very fast or complicated movements might not look smooth.

• Background quality: The quality of the background depends on the quality of your source image.

• Processing time: Sometimes the system is busy, and you might have to wait a bit longer for your video.

Being Fair And Honest

• Be transparent: Let people know that your content is made by AI, especially if you are building an influencer. A small note like #AIinfluencer is good.

• Don't create false information: Do not make scam ads or say things about a product that are not true.

• Respect brands: When you make content for a business, follow their brand rules.

• Impact on real creators: Be aware that this technology can affect the jobs of real actors and content creators. Use it responsibly.

Advanced Techniques

When you are comfortable with the basic steps, you can try these advanced methods:

Character Consistency

The first advanced technique is about keeping your character looking the same, which is called character consistency. A great way to do this is to create a "character sheet." This is a collection of pictures showing your character from different angles and with different expressions, like happy or surprised. You can use these pictures as your starting images to keep the look consistent in all your videos. It also helps to always use similar prompts for lighting and quality for all your source images to maintain a professional look.

Storytelling

You can also improve your videos by using storytelling. Instead of just a simple clip, try to plan stories that have multiple scenes. For example, a video can start with your character having a problem, then they find a product that helps solve it, and the video ends with them being happy with the result. Using different locations in your videos can also help you tell more complete and interesting stories.

Brand Integration

Finally, if you are working with clients, good brand integration is very important. This means you should always study the client's brand rules carefully before you start. The goal is to create content that feels true to the brand's voice and style, so it connects well with their customers.

The Future Of This Technology

This is just the beginning. AI video technology is getting better very fast, and people who start using it early have a big advantage. While other people are still just learning about these tools, you can be building a business, learning new skills, and getting known in the market.

The Google student offer ends on October 6, 2025, so if you are a student, use that free year of access. Even if you are not a student, the limited free credits are enough to get you started.

Conclusion

Creating AI influencers and UGC ads is not just possible - it's a practical and profitable thing you can start doing right now. You can choose to build virtual personalities or help businesses with UGC content. Either way, you are entering a market with big potential and not much competition yet.

The technology is ready, the tools are available (many are free), and businesses need this content. What you do with this opportunity is up to you.

Start with the free options, try different ideas, and don't be afraid to make mistakes. Your first few tries might not be perfect, but that's part of learning. The most important thing is to start.

Remember: while everyone else is just talking about AI, you can be using it to build a real business. The future belongs to those who take action today.
