Creating professional videos no longer requires cameras, lights, and actors. Today, all you need is a script and the right AI video tool. That’s where the showdown between Synthesia and HeyGen begins.
If you’re trying to choose between these two popular platforms, this synthesia: heygen review breaks it all down—features, pricing, usability, quality, and quirks. I’ll walk you through everything based on real experiences, test results, and insights that go beyond the marketing fluff. So, grab your coffee, and let’s explore which AI video platform truly deserves your time and money.
Better than HeyGen
What is Synthesia and What is HeyGen?
Both Synthesia and HeyGen are AI video generation tools designed to help you create lifelike videos using virtual avatars. But they each bring something slightly different to the table.
- Synthesia is known for its polished, corporate-style avatars, powerful multilingual support, and precise lip-syncing.
- HeyGen, on the other hand, takes a slightly more casual and expressive approach, giving creators more personality-rich avatars and unlimited video creation in all plans.
Both tools promise the same thing: ditch your video production crew, and just write your script to get a professional video in minutes. But are they really equal? Not quite.
Let’s start with how each tool handles its core mission—creating realistic AI videos.
Ease of Use: A Smooth Ride or a Bumpy Road?
When I first opened Synthesia, I was surprised by how intuitive it felt. Everything—from writing a script to choosing an avatar—worked like building a PowerPoint slide. It walks you through the process step-by-step:
- Write or upload your script.
- Choose an avatar and voice.
- Pick a background or use templates.
- Customize scenes like a slideshow.
- Export your video.
The entire editor is clean and built for non-techies. You don’t need editing skills at all.
HeyGen also keeps things simple but leans a little more into flexibility. You get drag-and-drop tools, dynamic camera motions, and more freedom in avatar movement. While Synthesia focuses on structure and professionalism, HeyGen feels more creative.
For casual educators, marketers, or creators who want more life in their videos, HeyGen might feel friendlier.
Avatar Quality: Realistic or Robotic?
Let’s talk avatars—because this is where the magic (or disconnect) happens.
Synthesia’s avatars are visually stunning. With over 230 options representing various ethnicities and professions, they look just like real people. Their lip-syncing is solid, and their eyes don’t wander like some cheap knockoff animations. But—there’s a catch. These avatars can feel cold. Almost robotic.
Watching a Synthesia video is like being at a well-rehearsed corporate onboarding. Clear. Sharp. But emotionless. You listen, but you don’t feel anything.
Now switch over to HeyGen, and the difference is clear. The avatars blink, nod, shift their bodies slightly. You notice micro expressions, and somehow the whole vibe feels more human.
If you’re aiming to connect emotionally with your audience—say, for YouTube videos or personal storytelling—HeyGen’s avatars win this round.
Pricing: A Smart Investment or Budget Breaker?
Here’s a breakdown of how pricing stacks up between the two:
| Plan | Synthesia | HeyGen |
|---|---|---|
| Free Plan | 36 minutes/year (limited features) | 1 free video, watermark included |
| Starter Plan | $18/month (180 minutes/year) | $29/month, unlimited videos |
| Creator Plan | $59/month (360 minutes/year) | $89/month, more avatars and tools |
| Enterprise | Custom pricing | Custom pricing |
Important Note: Synthesia charges based on video minutes, while HeyGen gives unlimited video creation on all paid plans.
That’s a game changer for people or teams producing content weekly or daily. If you create more than 10 videos a month, Synthesia’s per-minute model can quickly burn a hole in your wallet.
But here’s the thing—you get what you pay for. Synthesia’s polish, control, and language support may justify the cost for enterprise use. For casual content creators, HeyGen offers more bang for the buck.
Languages and Voice Cloning: Go Global or Stay Local?
Both tools support multilingual video creation, but Synthesia really shines here.
- 140+ languages
- Accents from all over the world
- One-click video translation
- Optional closed captions
- Voice cloning (on paid plans)
If your audience spans multiple countries—or if your brand is global—Synthesia’s localization tools make it easy to reach viewers in their native tongue.
HeyGen also supports many languages, though not as comprehensively. The voice quality in HeyGen is more expressive, but less consistent in syncing.
For global businesses, Synthesia is the clear winner.
Customization: Who Lets You Get Creative?
Synthesia has a structured, polished video builder with transitions, templates, and branding tools. You can change:
- Fonts
- Backgrounds (coffee shops, offices, etc.)
- Accent of the avatar
- Music and color themes
But there’s a ceiling. You can’t animate avatars beyond standing and talking, and camera motion is static. Think formal presentation.
HeyGen goes a step further.
You can animate avatars to walk, turn, and interact with props. You also get a “talk-to-avatar” mode where the AI can hold conversations—ideal for simulations, training, and fun interactive videos.
So if creativity and movement matter to you, HeyGen gives you more playground space.
Templates and Team Collaboration: Is It Scalable?
Synthesia comes packed with over 250 video templates for onboarding, sales, support, compliance, and education. These are industry-focused and make team collaboration super efficient. You can leave feedback, co-edit, and manage assets across teams—ideal for larger organizations.
HeyGen has fewer templates but offers customization options that are better for individual creators or small businesses.
If your company needs scalable video production with consistency, Synthesia’s structure is more valuable.
But for solo creators, digital marketers, or freelancers, HeyGen’s flexible template style might suit you better.
Real-Life Use Case: My Test Experience
To test both tools, I recreated the same video—a 90-second sales training clip—on both platforms.
- In Synthesia, the script was instantly turned into a clean, professional scene with an avatar that clearly spoke each line. It felt perfect for B2B use, but it lacked energy. Like a digital trainer who never blinks.
- In HeyGen, the same script had more flair. The avatar blinked, made hand gestures, and the pacing felt natural. It felt like I was watching a real person deliver the pitch.
That’s when I realized: Synthesia is your corporate trainer. HeyGen is your charismatic startup founder.

Custom Avatar Creation: Becoming Your Own Digital Twin
One of the coolest features both platforms offer is the ability to create your own AI avatar. But how easy is it—and how good are the results?
Synthesia’s Avatar Builder
Creating a custom avatar in Synthesia is pretty straightforward:
- Record yourself for about 5–10 minutes using their guidelines.
- Upload the footage.
- In about 24 hours, you get your digital twin, ready to speak any script.
The result? Surprisingly good. The avatar mirrored my facial structure, voice tone, and even quirks like my smile. However, it still felt… a little plastic. If you’re expecting it to fully replace human presence, it’s not quite there yet.
But for brand consistency and scalability—especially for corporate training or executive messaging—it’s a huge win.
HeyGen’s Avatar Builder
HeyGen also lets you build your avatar, but it adds more movement and energy to it. The recording guidelines are looser, and processing time is often quicker.
Your avatar feels more animated, which is great for YouTube creators, influencers, or sales videos where energy matters. However, the facial accuracy is sometimes a hit or miss.
So, for professional polish, Synthesia’s clone is better. But for creative personality, HeyGen shines.
Ethical Boundaries and Restrictions: What Can’t You Say?
This is an important piece many skip over.
Both platforms restrict certain types of content—especially when using pre-designed avatars:
- No political statements
- No medical advice
- No religiously sensitive topics
- No profanity or harmful speech
Why? Because the faces used in avatars are based on real people. So, they legally protect the identity of those individuals.
If you need full speech freedom, creating your own custom avatar is the only option. Even then, Synthesia applies tighter moderation than HeyGen.
So, if your content involves edgy humor, political commentary, or opinion-driven storytelling, HeyGen gives you more flexibility.
Customer Support and Community: Who’s Got Your Back?
Let’s face it—no matter how easy a tool is, things can go wrong. So how’s the support?
Synthesia Support
- Fast email support (within 24 hours)
- Great documentation
- Live onboarding for paid plans
- Enterprise-level SLA
They also have a growing user community, mostly filled with business users, L&D professionals, and marketers.
HeyGen Support
- Live chat (only on higher plans)
- Helpful tutorials and guides
- More active presence on YouTube and Discord
HeyGen has a younger, more creative community that often shares tips, templates, and fun video hacks. If you like learning by community, HeyGen is more engaging.
