If you need a short clip out today, HeyGen gets you there with fewer steps. If the video has to go through a team and come out on brand every time, Synthesia is the one built for that.

Read the Synthesia reviewWhat this is based on. Both vendors publish their plans, and those published terms are what this comparison is set on. ElevenReview does not run hands-on tests. Where the two platforms differ on something no document settles, we say so and keep the judgement tied to what is checkable. The named sources sit in the Sources block, each with the date it was checked.
Quick comparison
The rows that decide most purchases. Scores are editorial ratings out of 5, taken from each full review and built on the sources those reviews cite. A criterion is only tagged as a win when the difference is a fact a published source can settle, such as a feature that sits on one plan and not the other, or a spec each vendor states. Two scores a few tenths apart tell you little on their own, so those rows stay untagged. Team and brand controls is the exception, and what separates it from the rest is documentation rather than price: both vendors put a brand kit at the top of the range, but they differ in how far each one documents the controls behind it.

How they compare on each criterion
Five criteria decided this comparison, weighted toward avatar realism and editor speed because that is where these two platforms separate for the people who read it. These are the same five axes each full review is scored on, so the numbers are the reviews’ own. The overall ratings quoted at the end come from each full review, where they are published as that review’s weighted result across these five.
Avatar realism
How convincing the presenter looks when the viewer has not been told it is generated.
This is the one criterion no published source can settle, so the score is our editorial judgment. It comes from each platform’s own published demo footage and the avatar libraries its plans list: HeyGen’s preset avatars read the more natural of the two, and its stock of them is the deeper one on comparable plans. Synthesia’s output tends to sit closer to a studio recording than a webcam capture, which is a different look rather than a worse one. If realism is what your audience will judge, watch both vendors’ demos directly before you decide.
Editor speed
How few steps sit between a pasted script and a finished export.
HeyGen’s published flow is the shorter one: paste the script, pick a voice, and you are drafting, with no timeline to assemble first. Synthesia puts a scene-based editor in front of the same task, which is more setup for a single clip but is aimed at projects with many scenes and many people reviewing them. That shape, fewer steps for one clip against more structure for a programme of them, is what the speed score reflects.
Language and voice coverage
How far each platform reaches beyond English, and how it handles a non-English script.
Both cover the major business languages, and neither is the limit for an ordinary marketing script. The two scores meet at 4.6, and the published counts sit close behind them: HeyGen’s plan list quotes 175 languages and dialects once you pay, against 30+ on the free plan, while Synthesia counts 160+ languages and voices starting on the free plan, with dubbing running from 70+ on the entry paid tier to 140+ on Enterprise. What neither number settles is depth, meaning how many different voices a single language offers and whether they hold up on technical vocabulary. Which of those matters more depends on whether you need a rare language or a choice of voices in a common one, so check the specific voice list you would use before you commit.
Team and brand controls
Can several people work in the same account without the output drifting off brand?
HeyGen ships the same pieces, but they sit at the top of its range: a brand kit that holds fonts, colours and logos steady across a team’s videos, plus comments and an approval step where an editor accepts or turns down an edit request. All of that is on Business, billed per seat, and nothing below it holds more than one user. Synthesia keeps its matching controls on Enterprise, a tier it quotes rather than lists, and documents more behind them: brand assets that cannot be published unless they were approved, a Brand Admin to own the kit, permissions set per folder for viewing, commenting and editing, an audit trail, and SCORM export into a learning system. That documented depth, rather than the finished video, is what the score reflects.
Price and value
What you actually pay once the team, not one person, needs a seat.
The two entry plans sit a few dollars apart, so the decision comes down to what happens as you add people. On HeyGen, seats arrive with Business, listed at $149/mo plus $20 per seat, and 4K export sits one step up on Pro. Synthesia undercuts on the entry price, but every plan of its list below Enterprise is built for one editor, and what a team seat costs is not published at all. Once either platform is bought for a team, the comparison is no longer between the two headline numbers but between two upper tiers, one listed and one quoted. For someone posting a single clip a month, the free plan covers it and a subscription is hard to justify.
Which one should you pick?
Choose HeyGen if you ship clips on your own
- You publish short, presenter-led videos at least weekly and want the shortest path from script to export.
- One or two people handle the whole video process, so seats and approval steps would be features you pay for and never use.
- Your audience will judge the look of the presenter, not the admin panel behind it.
Choose Synthesia if the video has to pass a review
- Someone other than the maker approves a video before it goes out, and the budget reaches the Enterprise plan where that control sits.
- Every video has to match a fixed brand look across fonts, colours and logo, enforced rather than merely requested.
- You produce training or onboarding content in more than one language and want the translation handled inside the tool.
Choose neither if you only need a voice, not a finished video. Both platforms here are priced around rendering clips, and for narration alone a dedicated voice tool does the same job for less. Read the ElevenLabs review
Frequently asked questions
Is HeyGen or Synthesia better for someone making their first AI video?
HeyGen, for the first few videos. Both have a free plan, though Synthesia withholds downloads until you pay, and both walk you through a script-to-video flow. HeyGen simply asks for fewer decisions before you see a result, so it is the easier place to learn what your script needs to sound like.
Can I use my own avatar and voice on both platforms?
Yes, on both, with caps that differ by plan. The HeyGen free plan allows one cloned voice and up to three photo avatars, on top of a single custom avatar; paying lifts those caps. Synthesia offers the same two features behind a consent step that has to be completed before an avatar can be used, so its plan list is where to check the allowance you need.
Can I move an avatar or voice I already cloned to the other platform?
Not as a file. A cloned voice or avatar stays tied to the account that built it, so switching means rebuilding both from the same source footage on the other platform and repeating the consent step. If a switch is on the table, do that rebuild during the free trial, before you have a library of finished videos on either one.
Can a client approve a video without paying for a seat?
Viewing a finished export needs no seat on either platform; commenting inside the tool is what costs. HeyGen keeps its review features on Business, while Synthesia includes a few guest seats on its paid plans for people who never make a video. The guest counts differ by tier, so check the plan list for the allowance you need.
Which one handles a longer training video better?
Synthesia, on the strength of where each vendor aims its product. The material Synthesia publishes targets longer training and corporate learning content, where even narration across a long script matters, while the HeyGen material centres on shorter marketing and social clips. If the video you need is a long training module, weigh that positioning first.
HeyGen for speed, Synthesia when a team has to sign off
The split comes down to what you are making. HeyGen is the better single clip: the shorter workflow and the more convincing preset avatars earn it the higher overall rating in our full HeyGen review, 4.7 out of 5. Synthesia is the better system rather than the better clip, and its own review puts it at 4.6, because once several people are involved the controls behind the video matter more than a few saved steps. If your videos go through a review before they go out, pick Synthesia and accept the heavier single-clip workflow.
