Synthesia Review
After creating 50+ training videos with Synthesia over the past year, it's transformed how our team approaches video production. The new Express-2 engine with full-body avatars and upcoming Video Agents (interactive avatars coming 2026) represent the most significant leap in AI video generation I've seen-professional results without cameras, studios, or editing skills.

Feature Analysis
I've stress-tested Synthesia 3.0 including the new Express-2 avatars across training, marketing, and internal comms. Here's where it excels-and where traditional video still has advantages.
AI Avatars
240+ stock avatars with the new Express-2 engine deliver remarkably natural full-body gestures. Personal avatars let you clone yourself or team members. The quality gap between AI and real video narrows with each update.
Text-to-Speech
140+ languages with natural-sounding voices. Pronunciation is excellent for most languages. Voice cloning (Express-Voice) creates personalized voices for your avatars. Occasional awkward phrasing in longer scripts.
Video Translation
Translate existing videos into new languages while preserving lip-sync. Perfect for scaling training content globally without re-recording. The AI dubbing is seamless enough that viewers don't notice.
Ease of Use
No video editing experience needed. Write a script, select an avatar, generate. The interface is intuitive-most users create their first video in under 30 minutes. Templates accelerate production further.
Screen Recording
Built-in screen recording for software tutorials. Combine avatar presenter with screen captures in one workflow. Works well but not as feature-rich as dedicated screen recording tools like Loom.
Creative Flexibility
Best for professional/corporate content. Less suitable for creative projects requiring artistic direction, custom animations, or unique visual styles. The avatar aesthetic is corporate by design.
The Honest Truth
Based on 50+ training videos created across L&D, marketing, and internal communications, including extensive testing of Synthesia 3.0 and Express-2 avatars.
- Express-2 Avatars Are a Game-Changer - Full-body avatars with natural gestures eliminate the uncanny valley problem. The October 2025 Synthesia 3.0 update delivered avatars that look remarkably human. Viewers often can't tell they're AI-generated.
- 140+ Languages Without Reshoots - Create once, translate everywhere. Training content that took weeks to localize now takes hours. AI dubbing preserves lip-sync across languages. Global L&D teams can scale instantly.
- No Production Overhead - No cameras, studios, lighting, or video editing skills required. Write a script, click generate. Cohesity created 3-minute videos in less than half a day with 80% watch rates-production that previously took weeks.
- Proven Enterprise ROI - Zoom saves $1,000-1,500 monthly per employee. DuPont achieves 80% faster video creation and $10,000+ savings per video. The case studies are consistent: Synthesia delivers measurable cost and time savings.
- Video Agents Coming 2026 - Enterprise tier gets first access to interactive avatars that can respond to viewer questions in real-time. This could transform customer support, sales demos, and training from passive to interactive.
- Not for Creative Projects - The avatar aesthetic is professional but corporate. If you need artistic, cinematic, or highly branded video content, traditional production or tools like Runway are better suited.
- Custom Avatars Are Expensive - Studio Express-1 custom avatars cost $1,000/year. Personal avatars are included in paid plans, but creating a truly unique branded avatar requires enterprise investment.
- Minute Limits Can Feel Restrictive - Starter gets 10 minutes/month, Creator gets 30. High-volume video operations may burn through limits quickly. Enterprise with unlimited minutes is expensive but necessary for heavy users.
- AI Voice Uniformity on Long Scripts - Extended scripts can reveal the AI nature of voices-pacing becomes predictable, emotion flattens. Breaking long videos into segments with varied avatars helps, but isn't ideal.
Who Should Use This
Synthesia excels at professional business video. Here's who gets the most value-and who should stick with traditional video.
L&D Teams
Training videos at scale without production overhead. TTEC reduced video processing time by 70%. Zoom accelerated training production by 90%. The perfect use case for Synthesia's strengths.
Best FitCorporate Communications
Internal announcements, onboarding videos, policy updates-all without scheduling executives for recording. DuPont saves $10,000+ per video. Create consistent messaging across global offices.
Best FitMultilingual Content
140+ languages with AI dubbing that preserves lip-sync. Translate once, deploy globally. TTEC delivers content in 4 languages from a single source video. Essential for international operations.
Best FitSoftware Tutorials
Screen recording + avatar presenter creates polished tutorials without on-camera appearance. Good for product documentation and how-to content. Not as feature-rich as Loom but gets the job done.
Good FitCreative Video Projects
The corporate avatar aesthetic doesn't suit artistic or highly creative projects. For cinematic content, music videos, or brand films, traditional production or tools like Runway are better.
Not IdealTestimonials & Interviews
When authentic human connection matters, AI avatars feel wrong. Customer testimonials, thought leadership interviews, and trust-critical content need real humans on camera.
Not Idealvs. Competition
How does Synthesia compare to other video creation tools? I've tested all of these for different use cases.
My take: Synthesia dominates AI avatar video for business-240+ avatars, 140+ languages, and the Express-2 engine are unmatched for professional quality. HeyGen is the closest competitor with lower pricing and faster avatar cloning, but fewer language options. For creative projects, Runway's Gen-3 Alpha is better. For screen recording and async video, Loom remains superior. Descript excels at editing-first workflows. Many teams use Synthesia for training content alongside Loom for quick async videos.

Final Verdict
The Enterprise Standard for AI Video
Synthesia has earned its position as the market leader for AI avatar video in business contexts. The Express-2 engine delivers avatars that are genuinely hard to distinguish from human presenters, 140+ languages enable global scale without reshoots, and case studies from Zoom, DuPont, and Cohesity prove the ROI. Is it perfect? No-creative projects need other tools, custom avatars are expensive, and minute limits can be restrictive. But for L&D, corporate communications, and multilingual content at scale, Synthesia is the clear choice. The upcoming Video Agents feature could make it essential for interactive experiences as well.
