AI Content Stack: Bringing a Brand Character to Life with ChatGPT, ElevenLabs, and Hedra AI

Today, brands need more than polished visuals to stand out—they need a voice, a face, and a vibe that feels alive.

That’s exactly what we set out to build for Different Breed Elite Fitness: an animated coach that speaks directly to the culture of the gym. This coach delivers weekly Motivation Monday content—short, hard-hitting, and unforgettable.

Here’s how we brought him to life using ChatGPT, ElevenLabs, and Hedra AI—and why this approach became one of our highest-performing creative assets.

Step 1: Define the Voice and Persona in ChatGPT

We started by using ChatGPT to create the coach’s persona. This wasn’t just about dialogue—it was about embodying the gym’s brand energy.

We generated scripts that sounded like someone in the gym talking to you mid-set: short phrases, strong cadence, clear attitude. Prompts like:

“Write a motivational 10-second voiceover in the tone of a gritty boxing coach who’s pushing someone through their limits. Use the phrases: ‘Just Work,’ ‘Want vs. Need,’ and ‘Be Absolutely Different.’”

The tone became the character’s signature. No fluff—just focused, encouraging intensity.

Step 2: Generate the Voice with ElevenLabs

With the script in hand, we used ElevenLabs to generate a voice that matched our coach’s look and feel.

Using a custom-trained voice profile, we adjusted pacing, energy, and emphasis to give the delivery bite and rhythm. Tags like [pause], [strong close], and [calm then escalate] helped refine the experience.

The final voice felt real—like someone you’d actually follow, trust, and show up for.

Step 3: Bring It to Life with Hedra AI

Then we brought our coach to life visually with Hedra AI.

Using an illustrated character and the ElevenLabs voiceover, Hedra generated synchronized lip movement, facial expressions, and branded visual assets (like Different Breed gear, hat, and logo placement).
No film crew. No green screen. Just AI-driven animation that felt sharp, fast, and brand-specific.

The Result: One of Our Highest Performing Content Pieces

We ran a short campaign featuring the animated coach on Instagram and Facebook. With a modest ad spend, we achieved a CTR of 3.3%—well above average for fitness content in our niche.Even organically, the piece stood out as a top performer: it earned high engagement, drove meaningful profile actions, and reinforced our brand voice without needing weekly shoots or editing cycles.

Why did it work?
Because the content didn’t just tell people what to do.

It embodied what the brand stands for—and did it in a way that felt modern, efficient, and emotionally charged.

Final Takeaway

This is the new model for brand storytelling at scale:

• Use ChatGPT to shape character and copy
• Use ElevenLabs to deliver powerful, human voiceovers
• Use Hedra AI to animate it all into a living, breathing presence
  

If you’re running a fitness brand, coaching business, or digital product with a strong personality, this stack gives you a way to scale that presence across platforms—without sacrificing quality or connection.This is how we made a character worth following.

And we’re just getting started.
