Why 90% of the Fortune 100 choose Synthesia
Not because of one feature, but because Synthesia does the whole job, from creating video to proving impact.
Studio-quality video, without the studio
Most tools make you choose between speed and control. Synthesia gives you both. Turn a deck, a document, or a prompt into a finished video in minutes with the AI Video Assistant.
Then make it look professional without a video editor: generate custom B-roll from a prompt, add motion graphics and media from a built-in library, and apply your brand automatically, all while your team edits alongside you in real time.
"What used to take 4 hours now takes 30 minutes."
Rosalie Cutugno, Global Sales Enablement Lead
The most realistic avatars in business video
A talking head only gets you so far. Synthesia's avatars move, gesture, and carry the emotion of your script, powered by our proprietary Express technology. Prompt them to act in custom scenes and B-roll, create your own from a single photo or video, or pick from 240+ avatars and 1,000+ voices.
Put them side by side and it shows: in a blind test, people preferred Synthesia's best avatars to HeyGen's 7 times out of 10.
“It's enterprise-ready and makes video creation easy.”
Niraj Singh, Head of SAP Experience Garage
Reach every audience in their language
One market is a video. Twenty markets is a program. Synthesia turns a single video into a version for every market, each on brand and delivered in a voice that sounds native.
Translate into 160+ languages in one click, with your terminology and branding consistent in every version. Already have footage? Dub it into almost any language, keeping the original speaker's voice and matching their lip movements to the new audio.
Turn training into readiness
A real-time chat with an avatar makes a great demo. Turning it into skills that stick is the hard part. With Roleplay Sessions, people practice real conversations with Interactive Avatars that ask questions and push back, in scenarios shaped around your business.
An AI coach talks them through each session, digging into what landed, what didn't, and what to try next. Then measure skills uplift across individuals, teams, and the whole organization, so training turns into readiness you can prove.
“Interactive video is redefining training for us”
Jen Ruthven, Group Director, Learning & Career Development
Get video into your LMS, and prove it worked
A video only pays off when it reaches people inside the systems they already use. Synthesia publishes straight into your LMS with SCORM, embeds on any page, and personalizes at scale.
Video Analytics shows who watched, how much they watched, and who finished, so you can prove training landed and sharpen what didn't. And when something changes, fix the original once and every copy updates itself, everywhere it's embedded.
“Updating 10,000 courses? Totally doable now.”
Eva Bertone McGann, Senior Instructional Designer
Enterprise-grade security and governance, built in
Most tools let anyone publish anything. At enterprise scale, that's a liability. Synthesia lets you lock your brand so nothing drifts, and control exactly who can create, edit, and publish. And no one's likeness becomes an avatar without verified consent, while every video ships with built-in AI labels and content credentials, so you stay compliant.
It's built for the most regulated rooms, with SOC 2 Type II, ISO 27001, 27701, and 42001 and GDPR, and Synthesia is the first AI video company to earn ISO 42001.
“We make videos fast and use them every day.”
Prashanth Poli, Group Data & AI Strategy Project Manager
A team behind your whole rollout
Scaling video across a company takes more than software. Synthesia backs it with 24/7 live support, a dedicated Customer Success Manager, and a services team that runs pilots, onboarding, and creative production alongside you.
From first evaluation through procurement and global rollout, there's a Synthesia expert on your side, which is one reason Synthesia holds G2's Best Support award in enterprise.

Compare Synthesia vs HeyGen
In a blind study, 1,013 people compared the top avatars from each platform and chose Synthesia's 7 times out of 10.
ISO 42001 is the global standard for responsible AI management. Synthesia is the first AI video company to earn it.
Every Synthesia video can automatically carry a C2PA content credential and an AI label, to meet EU AI Act Article 50 and California SB 942 transparency rules.
On HeyGen, any edit re-renders the whole scene and spends credits again, so the real monthly cost climbs well above the sticker price. On Synthesia, you only pay for the seconds you change, not the whole scene.
Roleplay Sessions: practise real conversations with an interactive avatar, scored against a skills rubric with AI coaching and team analytics.
24/7 live support, a dedicated Customer Success Manager, and services for pilots, onboarding, and production.
Lock brand assets and templates across the whole workspace so nothing goes off-brand.
Several people editing the same video at the same time. HeyGen's mode allows only one editor at a time.
Turn a PowerPoint or PDF straight into video. Synthesia's higher limits mean a whole deck becomes one video.
Use a timeline to sync text, media, and animations to your script, and fine-tune any exact moment, instead of editing whole scenes at a time.
In an independent blind study, 1,013 people compared the top avatars from each platform and chose Synthesia's 4,379 times to 2,988.
Frequently asked questions about Synthesia vs HeyGen
What's the difference between Synthesia and HeyGen?
Both create AI avatar videos, but they're built for different jobs. HeyGen is designed for individual creators making quick, self-serve clips. Synthesia is a full platform for the team behind a video program, covering creation, localization, practice and coaching, distribution into your LMS, brand governance, and analytics in one place, with enterprise security and support. That's why more than 90% of the Fortune 100 use Synthesia.
Is HeyGen cheaper than Synthesia?
Both start at a similar entry price, so the sticker price looks the same. What you actually pay is not.
On HeyGen, any edit re-renders the whole scene and spends credits again, so re-editing, not making new video, is what eats the plan, and the real monthly cost climbs well above the headline price. It is a common complaint with HeyGen users.
On Synthesia, you only pay for the seconds you change, so fixing a line or updating a stat costs almost nothing.
HeyGen's headline minute allowances also assume their cheapest avatar, while Synthesia charges one flat rate per minute whatever the avatar.
And at scale, Synthesia enterprise plans include unlimited minutes.
How does Synthesia's avatar quality compare to HeyGen Avatar V?
Both platforms have strong, lifelike avatars, and HeyGen's Avatar V is a genuine step up in realism. But in a recent blind test, people preferred Synthesia's best avatars to HeyGen's 7 times out of 10. The test compared the top-performing avatars from each platform and was commissioned by Synthesia. Synthesia avatars run on our proprietary Express technology, so they move, gesture, and carry the emotion of your script.
Is Synthesia free to try?
Yes. Synthesia has a free plan with no credit card required, giving you access to stock avatars, the core editor, and video generation in 160+ languages. You can create your first AI video in minutes, then move to a paid plan when you need custom avatars, more features, or enterprise controls.
How many languages does Synthesia support compared to HeyGen?
Synthesia supports 160+ languages for avatar video, along with 1,000+ voices, and AI Dubbing covers a wide range too. HeyGen advertises a slightly higher language count, so both cover far more than most teams will ever use. The bigger difference is control: Synthesia keeps your terminology and branding consistent across every language, and viewers can switch language inside a single shareable video.
Does Synthesia have real-time interactive avatars like HeyGen's LiveAvatar?
Yes. Synthesia offers Interactive Avatars that listen and respond live, plus Roleplay Sessions, where people practice real conversations with an interactive avatar that asks questions and pushes back. Unlike a standalone real-time avatar, Roleplay Sessions wraps the conversation in scoring against a skills rubric, AI coaching, and team analytics, so practice turns into measurable skill.
How do I switch from HeyGen to Synthesia?
Synthesia's services team helps you move over with a guided pilot, onboarding, and a dedicated Customer Success Manager. You can rebuild key videos quickly from your existing scripts and decks, export finished content as SCORM for your LMS, and lean on 24/7 live support throughout. Most teams are creating and publishing in their first week.
Is Synthesia secure enough for regulated industries?
Yes. Synthesia is built for regulated environments, with SOC 2 Type II, ISO 27001, ISO 27701, and ISO 42001 certifications, GDPR compliance, and SSO and SCIM for access control. Synthesia is the first AI video company to earn ISO 42001, the global standard for responsible AI management, and every personal avatar requires verified, on-camera consent.
