Who made Synthesia AI?
Synthesia was founded in London in 2017 by CEO Victor Riparbelli and co-founders. The company raised a $200 million Series E in January 2026 at a $4 billion valuation, with over $530 million raised in total. Roughly 90% of Fortune 100 companies use the platform, including Bosch, Merck, SAP, and Teleperformance.
How does Synthesia AI work?
Write or paste a script, pick a stock or custom avatar and voice, and Synthesia generates a lip-synced video. One-click translation dubs the same video into dozens of languages, preserving the avatar's delivery, without re-recording or re-scripting.
What can you make with Synthesia AI?
Training and onboarding videos, sales enablement content, product tutorials, internal announcements, and multilingual versions of any of the above, all from the same script and avatar setup.
Synthesia 2.0: what's new in 2026
Synthesia's newest avatar engine, internally called Express-2, pairs voice cloning with a diffusion transformer model to produce full-body avatars with natural gestures rather than a static talking head. Personal Avatar creation now takes minutes from a short recorded sample. Video Agents, avatars that hold real-time conversations with viewers instead of playing a fixed script, are rolling out to Enterprise customers.
Synthesia AI output quality
Avatar realism is Synthesia's strongest claim, and it holds up: Express-2 avatars show natural facial expression, accurate lip sync, and full-body gesture that reads as a professional presenter rather than an animated template.
Voice naturalness is strong across the platform's stock voice library, and cloned voices preserve identity and accent closely enough to pass in a corporate training context.
Lip-sync accuracy is consistently tight across languages, a byproduct of Synthesia's dubbing-first design: the same avatar performance re-syncs to translated audio rather than generating a new take per language.
Render speed scales with video length and avatar count per scene; single-avatar training videos generate in minutes, and multi-avatar interactive scenes take longer.
The tradeoff is tone: the avatars are built and trained for corporate delivery. That reads as polished for training and internal comms, but feels rather stiff for UGC-style content where an authentic, off-script feel matters more than polish.
PROS
Express-2 avatars are among the most realistic corporate-presenter avatars available, with natural gesture and expression
Personal Avatar creation from a short recorded sample, no studio shoot required
AI Dubbing covers 70+ languages on paid plans and 140+ on Enterprise, re-syncing the same performance rather than re-recording
PowerPoint import turns existing decks into narrated video without a new script
SCORM export and major LMS integrations (Docebo, Litmos, Cornerstone) built for training delivery
SOC 2 Type II, GDPR, and ISO 27001 certified, with consent-based avatar creation and content moderation
CONS
Free plan caps at 10 minutes of video a month, no MP4 download, preview and watermark only
Starter's 3 personal avatars and 125+ stock avatars sit well below Creator and Enterprise tiers
Avatars read as corporate-polished, which works against authenticity in UGC-style ad creative
No ad-specific tooling: ad templates, competitor tracking, and direct ad launching aren't part of the platform
API access and branded video pages are gated to Creator ($89/mo) and above
Video Agents (real-time conversational avatars) are Enterprise-only, not available on Starter or Creator
Who should use Synthesia AI?
Enterprise L&D teams standardizing training across large workforces, global companies localizing internal content into dozens of languages, educators and course creators building structured video curricula, and HR teams that need consistent onboarding at scale.
Not recommended for
Performance marketers running paid ad campaigns, DTC brands and UGC creators who need an authentic, off-script feel, and teams that need competitor tracking or a direct path to launching and managing ads on Meta or TikTok.

Synthesia's entry price is lower, but the free and Starter tiers cap video minutes hard (10/month free, 120/year on Starter), and API access, branded pages, and interactive video don't unlock until Creator at $89/mo. Creatify includes video ad creation on every paid plan from the entry tier, with no video-minute ceiling to work around.
Synthesia's edge is presenter realism at enterprise scale: Express-2 avatars, tight lip sync, and dubbing into 140+ languages from a single performance, built for training and internal comms where consistency and polish matter more than authenticity.
Creatify's edge is ad performance: finished creative built around a hook, pacing, and a call to action, benchmarked against other ad-generation systems. VideoAdAgent Bench v1 puts Creatify Agent at a 94% win rate against competing AI ad agents on finished-ad quality. Synthesia's corporate-polished tone works against it here; it reads as scripted where UGC-style ads need to read as authentic.
