How to Use a Free AI Consistent Character Generator (Step-by-Step Guide)

Generate and Animate Consistent AI Characters for Free

Creating AI-generated characters is fun—until your favorite character suddenly changes face, hairstyle, or even gender in the next image. If you’ve been struggling to make your AI characters look the same across different scenes, you’re not alone. The lack of facial consistency is one of the biggest frustrations for creators working with AI image tools.

The good news? There’s now a reliable way to fix that using free AI consistent character generator tools—namely ImageFX and Digen.ai. In this step-by-step guide, you’ll learn how to generate consistent, high-quality AI characters for storytelling, branding, animation, or content marketing without paying a dime.

What Is an AI Consistent Character Generator?

An AI consistent character generator is a method or toolset that allows you to create the same character multiple times across different images, styles, or settings—while keeping their facial features, hair, and overall identity the same. While most AI tools generate characters from scratch each time, this guide shows you how to maintain consistency by using smart prompts, seed locking, and scene management.

Step 1: Build a Strong Character Profile

The foundation of any consistent character generation lies in defining your character upfront. One of the most common mistakes people make is using vague descriptions. Remember: AI doesn’t have memory—it only generates based on the input it receives each time.

Tips for a Solid Character Profile:

Name: Give your character a name.
Age and Ethnicity: Specify age range and background.
Facial Details: Mention eye color, face shape, any distinctive features (scars, freckles, etc.)
Hair: Describe hair type, length, color, and style.
Style and Clothing: Be specific—don’t just say “futuristic outfit”; say “black leather trench coat with glowing blue edges.”
Backstory (Optional): Helps add creative depth for storytelling.

Example:
Phionah is a 28-year-old woman with sapphire blue eyes, straight but slightly wavy dark hair, and sharp cheekbones. She wears a modern trench coat and carries a vintage darkish camera.

Step 2: Generate Your Character in ImageFX

Once your profile is ready, it’s time to bring your character to life using ImageFX—a free AI image generator developed by Google.

Key Settings for Character Consistency:

Use a single style preset (stick to one throughout the session)
Enable High Detail Mode: This reduces random variations.
Opt for Realistic Lighting: This helps the AI “lock in” facial structure.
Use Descriptive Prompts: Feed the full character profile into the prompt box.

Hit “Generate” and let ImageFX render your character.

Step 3: Lock the Seed Number

Even if you use the same prompt twice, AI tools can produce different results each time. Why? Because each generation begins from a different starting “seed.”

The Fix:

Lock the seed number in your AI generator (if the tool allows it). This ensures your character’s face, expression, and structure remain consistent across different poses and backgrounds.

Once locked, every new image you generate based on that seed will retain the same character identity.

Step 4: Drop the Character into Different Scenes

Now that your character is consistent, it’s time to put them into dynamic environments—pyramids, neon cities, outer space, or anywhere your story takes them.

How to Do It:

Keep the character description the same
Add scene or background details to your prompt
Maintain the locked seed

For example:
“Jenny, a 30-year-old woman with blue eyes and brown wavy hair, walks through ancient Egyptian pyramids under golden sunlight.”

This method ensures the environment changes but the character remains identical.

Step 5: Build a Visual Story with ChatGPT

Why stop at one image? With the help of ChatGPT, you can turn your character into the protagonist of an AI-powered visual story.

How:

Ask ChatGPT to write a short story around your character.
Break the story into visual moments or scenes.
Use your consistent prompt and locked seed to generate images for each scene using ImageFX.

You now have a fully illustrated visual story with consistent character identity.

Step 6: Animate Your Character with Digen.ai

Want to bring your character to life with movement and sound? That’s where Digen.ai comes in—a free platform that animates AI images into short videos.

Steps:

Go to Digen.ai and start a new project.
Drag and drop your generated image into the workspace.
Paste the scene description into the prompt box.
Add background music or upload your own.
Generate and download your animated video.

You can animate daily for free (1 credit per day), and while the free version includes a watermark, it’s perfect for testing and learning.
