HeyGen vs Synthesia, compared on a published method
Six controlled rounds, one reviewer who refused to let his own score decide, and the price arithmetic neither vendor publishes.
The short answer
On HeyGen vs Synthesia both entry tiers cost $29 a month and buy different things: 30 minutes per video against 10 minutes per month.
On quality there is one published controlled test. Marcus Taylor of Venture Harbour scored Synthesia the winner of 4 of 6 rounds, then refused to let that decide the purchase.[1]
HeyGen vs Synthesia: the one controlled test anyone has published
Nine pages rank for this comparison. Two are the vendors themselves, one is a third vendor comparing the two products it competes with, one is a review marketplace and the rest are affiliate explainers. Not one of them ran the products against each other, which is why the comparisons desk exists at all.
Marcus Taylor of Venture Harbour did, and published the method alongside the result. His head-to-head test is the only one on this search term that a reader can audit, and this desk has not run either tool, so what follows is his work reported carefully rather than a verdict of ours.
| Tool | Round winner | What the round tested |
|---|---|---|
| Round 1: realism, simple script | Synthesia | A plain read to camera, both avatars trained from the same owner |
| Round 2: emotional range | Synthesia | A charged script, testing whether either avatar can carry feeling |
| Round 3: lip sync under load | Synthesia | A 31-word tongue twister, the round designed to break lip sync |
| Round 4: templates and native avatars | HeyGen | What each platform ships in the box, before any custom work |
| Round 5: photo-to-avatar | Draw | Five selfies into an avatar. The reviewer could not name a use for the output |
| Round 6: dubbing | Not completed | Synthesia's content guidelines declined the job, so the round never ran |
How this was scored. Marcus Taylor of Venture Harbour, published 2025-09-25, using one avatar owner, one ElevenLabs voice model held constant, the same scripts and a paid plan on both platforms, across six defined rounds with a declared winner per round, ordered here as he ran them and scored throughout by him rather than by this desk. How this table is built and checked.
The controls, and why they matter
The same person's face on both platforms, the same voice model driving both, the same scripts read by both, and a paid plan on each so neither was handicapped by a free tier. Those four controls are what separate a test from an impression.
Without them, a comparison is measuring the reviewer's script choices and plan selection rather than the products. That is what most of the pages ranking for this term are actually doing, and it is why their conclusions disagree with each other so freely.
Round by round
The rounds escalate deliberately: an easy read first, then feeling, then a deliberate attempt to break lip sync, then the parts of each platform that have nothing to do with realism.
Where avatar realism separated them
Taylor is specific about what gives an avatar away, and his ranking is not the one most buyers expect. Lip sync and the voice clone were consistently the strongest parts on both platforms, which means the uncanny valley on these tools opens somewhere other than the mouth.
That is worth carrying into your own evaluation. If you watch the mouth you will probably conclude both tools are solved, because on his evidence the mouth is the part that works.
The feature that made realism worse
Taylor reports that HeyGen's eye-correction variant of his avatar produced eyes that looked less realistic rather than more. A corrective feature moving the output backwards is the kind of thing only a hands-on test surfaces.
It is also a reminder that a feature list is not a capability list. Both platforms ship options that can degrade the result, and no comparison table has a column for that.
Photo-to-avatar, and an honest verdict on it
Round five fed five selfies into each platform. Taylor's assessment of the output was blunt, and it is the single most useful sentence for anyone hoping to skip the video training step.
The round that did not run
Round six was dubbing into a foreign language. It never completed, because Synthesia's content guidelines declined the job Taylor set it.
For most readers this is irrelevant, because most work is ordinary. For anyone with an unusual content mix, a regulated subject or a client whose material sits near a policy line, it is worth more than any round that did run. Find out before you buy the year.
Why the winner did not win the recommendation
Four rounds to one with a draw is a clear result, and Taylor declines to treat it as one. His summary sentence is the most reusable idea in this whole category.
Feature breadth, price and integrations sit outside a rendering test by construction. A head-to-head can only score what it renders, so the things that decide most purchases are structurally invisible to it.
- Anything that can be filmed gets scored. Anything that only shows up in the second month of use does not.
- Billing units, seat rules, content policies and integration coverage all fall into the second category.
That is a general problem with comparison content rather than a flaw in his test, and it is why this page reports his rounds and then puts the published prices beside them rather than declaring a winner on his behalf.
Synthesia vs HeyGen on what the prices add
The two vendors do not bill in the same unit, which is why their headline figures mislead. HeyGen Creator and Synthesia Starter both cost $29 a month and buy completely different things.
- HeyGen Creator: a per-video minute cap of 30 minutes, with no monthly ration at all.
- Synthesia Starter: 10 minutes for the entire month, with no cap on any single video.
Cost per finished minute on each vendor’s published tiers
Read that way the gap is wide, and it is the arithmetic behind Taylor's line about HeyGen costing significantly less. The full ladders live on HeyGen's published tiers and Synthesia's published tiers, each with the date the figures were read.
One caveat this desk applies to its own arithmetic: the HeyGen figure assumes one full-length video a month, which is the least flattering reading available for HeyGen. Anyone making several long videos a month gets far more from that plan than the number suggests.
A year of each entry tier, and what it permits
What a year actually costs
Twelve months of either entry tier is $348, and $216 if the Synthesia plan is taken annually rather than month to month. Those are the two numbers a reader is usually choosing between.
The step to Synthesia Creator is $1,068 a year, which is $720 more than a year of HeyGen Creator. Whether the realism edge in the rounds is worth that gap is the actual decision, and it is a judgement about your audience rather than about the tools.
Where the two sources disagree
This desk cites a second source on these two products, and it does not reach the same conclusion about who should buy which. That disagreement is reported rather than resolved.
Taylor's split is by output requirement: highest-quality avatar to Synthesia, everything else to HeyGen. The Cybernews tools desk frames the choice around whether a viewer notices the avatar at all, which is a different question and produces a different answer.
- Taylor's question: which platform renders the better avatar under test?
- The Cybernews question: will an ordinary viewer notice it is an avatar at all?
Two sources agreeing would be more comfortable to publish and less useful to read. A controlled test and a mainstream read of the same two tools produce different buying advice, and which one applies to you depends on whether your audience is watching closely.
Who is paying whom
Both cited sources earn commission on tools in this category. Taylor discloses his affiliate links in writing and says his rankings are set before any partnership. The Cybernews desk carries tracked affiliate links, which is why it is capped at two quotes across this whole site and never used for a number.
This desk sells neither tool and takes no commission on either. It sells guest placements, which is disclosed on its own page and has nothing to do with which avatar platform wins a round.
What is better than HeyGen
Nothing is better in general, and any page answering otherwise is selling something. On the evidence here, Synthesia is better at rendering a convincing avatar and HeyGen is better at almost everything surrounding one.
If HeyGen has already disappointed you on a specific axis, the useful next step is the alternatives page on this desk, which compares a wider field on the same stated method and includes tools this page does not cover.
What is better, Synthesia or HeyGen
The verbatim answer is a split, and the split is quotable rather than invented. Two questions settle it for most readers, and neither is about price.
- Will your audience watch the presenter closely, as they do in course material? That points at Synthesia.
- Do you need volume, integrations and a longer single video for the same money? That points at HeyGen.
Which is better for course material
Taylor's stated case for Synthesia is exactly this one: if you need the absolute highest quality avatar, for instance when creating course material, that is where he would go. Learners watch a presenter for a long time, and small realism failures compound over an hour.
Which is better for volume and integrations
His case for HeyGen is feature breadth, lower cost and the existence of integrations. For a marketing team pushing many short videos through an existing workflow, those three outweigh a realism edge that most viewers will not be looking for.
Is HeyGen Creator worth it
Decided by your longest planned video and your seat count, not by the $29. Creator permits 30 minutes in a single render, which clears almost anything a talking-head format should run to.
The tier above it does not raise that ceiling at all, so upgrading because a video came out too short is the most common wasted purchase on that ladder.
Is Synthesia worth it
Decided by monthly minutes and by whether you need a named presenter. Starter permits 10 minutes a month, which is the same allowance as its free tier, and Creator triples it for $89.
Against that, it is the platform a reviewer who ran both would choose when avatar quality is the thing being bought.
Who competes with Synthesia
HeyGen and D-ID are the two this desk prices alongside it, and the three between them cover most of what an AI video generator buyer will shortlist for talking-head work.
One detail worth naming: a fourth vendor ranks on this exact search term by publishing its own comparison of the two products it competes against. That is legitimate marketing and it is not independent evidence, which is a distinction this SERP makes it hard to see.
Personal avatars, and what each platform gives you
Both platforms sell the same idea under different names. A personal avatar on Synthesia and a custom digital twin on HeyGen are both an avatar trained on footage of one specific real person, as distinct from the stock presenters anyone can use.
The counts differ sharply at the tiers most readers buy: 3 personal avatars on Synthesia Starter against 1 custom digital twin on HeyGen Creator. A company with three spokespeople hits that ceiling long before it hits any minute limit, and the comparison above says nothing about it because a rendering test cannot.
- Training an avatar on a real person carries consent obligations neither vendor's marketing page dwells on.
- Those are a legal matter rather than a comparison one, and this site treats them separately for that reason.
What HeyGen vs Synthesia testing could not settle
One avatar owner is one face. Avatar quality varies with the training footage, the lighting and the person, so a result from one owner is evidence rather than proof.
- Voice tuning is not free: Taylor reports that moving the voice sliders without care made his clone sound wrong and added filler sounds. Budget time for it.
- Gesture tagging only works for gestures you actually performed in the training video. His were limited to pointing.
- Dubbing quality is judged on lip sync when you do not speak the target language, which he says plainly and most reviewers skip.
Why this page will age
The test was published in September 2025 and both products have shipped avatar upgrades since. Every claim here carries its date for that reason, and a realism verdict is the fastest-decaying thing on this site.
The prices are re-read quarterly and carry their own fetch date. The rounds are not re-runnable by this desk, so when a newer controlled test appears it will be reported alongside this one rather than quietly replacing it.
How we compared this
Humva's editorial desk has not run HeyGen or Synthesia. Everything above about output quality is Taylor's judgement, named in the sentence that carries it, with his affiliate disclosure attached.
- Rounds, controls and quality verdicts: Venture Harbour, 2025-09-25.
- The buyer-fit disagreement: the Cybernews tools desk, capped and never used for a figure.
- Every price: the vendors' own pages, read 2026-08-25, with cost per minute derived here.
How to run the tie-break yourself
Both platforms have a free tier, which makes a small version of Taylor's test cheap to repeat. Run it in his order and the answer usually arrives inside an hour.
A one-hour version of the six rounds
- Same script, both platforms Use one script of about 150 words on both. Free tiers cover this: HeyGen allows one minute per video and Synthesia ten minutes a month. 10 min
- Watch the eyes, not the mouth On the cited evidence lip sync is solved on both. Judge the eyes first and idle head movement second.
- Try the script that worries you If your subject sits anywhere near a content policy, test that before you test quality. One platform declined a job outright in the published test.
- Price it last Divide the plan you would actually buy by the minutes it permits. The headline figures are not the same unit. $0

The disclosure duty is yours, not the platform’s
Both platforms on this page will tell you their output is marked as AI-generated, and from 2 August 2026 the EU requires exactly that of them. It is worth being precise about who has discharged what. The marking obligation falls on the provider of the system. A second, separate obligation falls on whoever deploys a deepfake: they must disclose it to the people who see it.
A business publishing avatar video into the EU is the deployer. No feature either vendor ships satisfies that duty on its behalf, and the deployer’s duty is the one with no grace period, systems already on the market get until December for the marking rule, and nobody gets an extension on telling the viewer. If your comparison between these two tools includes a compliance column, this is the row that belongs in it, and neither vendor can fill it in for you.
What this does not say: The Commission FAQ is guidance, not the operative text, and the harmonised standards and Code of Practice that will decide what counts as adequate marking were not finalised at the date of reading.

China labels the upload, not just the tool
Since September 2025, AI video distributed in China has to carry two labels: one a viewer can see, illustrated in the national standard as an “AI” mark in the corner of the opening frame, and one embedded in the file’s metadata where only a machine reads it. That much is a production requirement, and both platforms here can be made to satisfy it.
The part that catches people out is who else the duty binds. A user who republishes AI-generated content on a Chinese platform has to declare it themselves and use the platform’s own labelling control. The obligation follows the upload, not the render, so a video made lawfully abroad and posted by a colleague in Shanghai puts the duty on the colleague. That is a workflow question rather than a tooling one, and it is the reason a distribution plan for China should name who presses publish.
What this does not say: A law-firm summary of a Chinese-language instrument; the primary text on chinalawtranslate.com returned HTTP 403 at the date of reading, so the specific metadata fields required were not verified against the standard itself.
