What Is HeyGen?
Creating marketing videos in different languages used to be a painful, costly process. Think actors, cameras, re-shoots, voiceover talent, translators—the list goes on. But here’s the good news: 2025 is the year AI finally took that pain off your plate.
I’m Eli Mercer. I experiment with the latest AI tools so creators and marketers don’t waste time chasing shiny objects. After testing HeyGen with my global content workflows, I’ve got one big question to unpack:
➡️ Is HeyGen the best AI video generator for creating multilingual marketing content in 2025?
Let’s get into what this impressive tool actually does, how it works for multilingual use cases, and whether it’s the right tool for your team.
What Is HeyGen?
HeyGen is an AI-powered video generation platform that turns text scripts into high-quality, human-like avatar videos—without cameras, actors, or video rigs.
Think Zoom-level simplicity meets Hollywood-level polish.
It was built for marketers, content creators, and global teams who want to scale video production fast without sacrificing quality or authenticity.
It’s already ranked #1 on G2’s 2025 Top 100 list 🔥—and once you see it in action, you’ll see why.
Why Marketers Are Switching to HeyGen in 2025
Here’s what’s exciting—HeyGen doesn’t just create AI videos. It helps you:
- Speak to multiple markets in multiple languages ⚡️
- Cut video production time from weeks to minutes
- Eliminate the need for film crews or bigger budgets
I personally tested it with Spanish, German, and Japanese scripts for a B2B brand funnel. Result? Crisp video output, perfect lip syncing, and emotionally on-brand avatars.
Let’s look at what makes HeyGen stand out.
HeyGen’s Multilingual Capabilities: A Global Game-Changer
If you’re marketing internationally in 2025, you need multilingual reach.
HeyGen nails this with built-in translation tools and voice synthesis across dozens of languages. You can either upload your own translations or let the AI translate and voice your script in languages like:
- Spanish 🇪🇸
- French 🇫🇷
- Japanese 🇯🇵
- Arabic 🇸🇦
- Hindi 🇮🇳
- and over 40+ more
But the real magic? You don’t just get word-for-word translations. It’s matched with culturally sensitive avatars and regional accent options—including Australian English, which most tools skip.
It sounds like hiring a local speaker—except it’s all AI.
How to Create a Multilingual Marketing Video in HeyGen (Step-by-Step)
Here’s what the actual workflow looks like:
- Start with a script
Write your base script in English or your preferred language. Or use HeyGen’s GPT-powered script assistant. - Translate (if needed)
Use the built-in translation tool to localize your message into one or more languages. - Choose an Avatar
Select from 100+ pre-made avatars, or upload your own to create a custom “digital twin.” - Pick Your Language + Voice
Choose from natural-sounding voices, dialects, and even specific accents based on region. - Customize Look & Feel
Add your branding, titles, and slides to match your campaign. - Click Generate
Boom. Your multilingual marketing video is ready to download or share.
This entire process took me under 30 minutes. I ran A/B tests in German and Spanish within the same campaign cycle—no additional filming. That’s game-changing.
What Makes HeyGen Different From Other AI Video Tools?
Let’s be honest—there are a lot of AI video generators out there: Synthesia, Veed.io, DeepBrain AI. Some are decent, others feel half-baked.
Here’s how HeyGen pulls ahead:
- ✅ Realistic Avatars → HeyGen is way ahead on facial animation and tone syncing
- ✅ Global Accuracy → Better localization and accent replication than Synthesia
- ✅ AI Studio → All-in-one workspace for script, voice, video, and branding
- ✅ Collaboration → Cloud-based editing for hybrid/remote teams
- ✅ Fast → Render a full HD video in under 5 minutes
It’s not just a tool. It’s a production studio in your browser.
HeyGen Pros and Cons
Let’s break it down 👇
✅ Pros:
- 70+ languages and multiple accents supported
- No cameras or mics needed—just type and build
- High-quality avatars feel professional
- Cloud-based collaboration for teams
- Free plan available with 100+ avatars included
❌ Cons:
- Limited customization on free plan
- Avatars still not 100% human-like (yet)

Still, if you’re using video across languages, the ROI clocks in fast.
