Quick Verdict + Rating: 79/100
Synthesia is the AI avatar video platform built for organisations that prioritise predictability, compliance, and team workflow over peak realism. Across our research it scores 79/100 — a strong second place in the AI Video Tools category behind HeyGen (82/100), and the leading pick for enterprises, regulated industries, and anyone whose internal procurement team has a security questionnaire to fill in.
The trade-off is honest: Synthesia’s avatars don’t quite match HeyGen’s Avatar IV for surface realism, and language coverage is narrower (140+ vs 175+). But you get a flat minutes-per-month pricing model that’s far easier to budget than HeyGen’s credits, SOC 2 Type II / ISO 27001 / GDPR compliance baked in, native PowerPoint integration, and a team collaboration layer that’s genuinely production-grade.
What Is Synthesia?
Synthesia is an AI video platform that generates avatar-led videos from text scripts. Users paste a script, choose an avatar and voice, and Synthesia produces a finished video of that avatar speaking the script with synchronised lip movements and natural delivery.
Founded in 2017 and headquartered in London, Synthesia is one of the longest-established avatar platforms in the market and has built its reputation on enterprise sales — over half of the Fortune 100 reportedly use Synthesia for internal training and corporate communications. The 2026 platform offers 230+ stock avatars, 140+ languages, custom avatar creation (on enterprise tiers), and a structured editor designed around teams producing video at scale.
Synthesia competes directly with HeyGen on the high-realism end and Colossyan on the team-collaboration end. Its pitch is unmistakable: the safest, most predictable AI avatar tool for organisations that need to ship video at scale without surprises.
Key Features
230+ Stock Avatars
Synthesia’s stock avatar library is one of the largest in the category, covering varied demographics, professional contexts, and styles. The avatars are designed for corporate, educational, and training video — the bias is towards “presenter-style” delivery rather than the more expressive social-content energy you’ll see in some HeyGen stock avatars. For most enterprise use cases this is the right choice.
140+ Languages and Accents
Synthesia supports 140+ languages and regional accents — narrower than HeyGen’s 175+ but still best-in-class for enterprise needs. Voice and avatar can be mixed across language boundaries, and the platform handles localisation workflows particularly well for teams producing the same content across multiple regions.
Custom Avatars (Enterprise Tier)
Synthesia offers custom avatar creation, but it’s gated behind enterprise contracts rather than offered at a self-serve price like HeyGen’s $99/mo tier. The trade-off is that Synthesia’s custom avatar process is more controlled — typically involving a managed onboarding session and a higher-fidelity capture process. For enterprises wanting brand-exact custom avatars with strict consent and usage governance, this is the right model. For solo creators or small teams who want a custom avatar today at a self-serve price point, HeyGen is the better fit.
Compliance Stack — SOC 2 Type II, ISO 27001, GDPR
This is the single biggest reason Synthesia wins enterprise procurement battles. SOC 2 Type II, ISO 27001, and GDPR compliance are not just badges — they’re the baseline requirements for getting an AI tool past most enterprise security teams. Synthesia also offers content moderation controls and avatar consent tracking that are genuinely more mature than competitors. For regulated industries (financial services, healthcare, government, pharma), this stack alone often makes the buying decision.
PowerPoint Integration
Native import from PowerPoint converts existing slide decks directly into avatar-led videos. For corporate L&D and internal comms teams sitting on hundreds of training decks, this is a significant productivity unlock. HeyGen has similar integrations but Synthesia’s PowerPoint pipeline is more mature.
Team Collaboration
Multi-user workflows, role-based permissions, brand kit management, and review/approval flows are all built in. This is video production for organisations, not for solo creators — and it shows in the structure.
Predictable Pricing — Minutes per Month
Synthesia bills by video minutes per month rather than credits. The $18/mo Starter tier includes 10 minutes; Creator at $64/mo includes 30 minutes; enterprise tiers include custom allocations. This model is much easier to forecast and budget than HeyGen’s credit system, which trades flexibility for predictability.
Pricing Breakdown
| Plan | Price | What You Get |
|---|---|---|
| Free | £0 | 3 minutes total (lifetime), watermarked, stock avatars only |
| Starter | $18/mo (annual) | 10 video minutes/month, stock avatars, 9 languages |
| Creator | $64/mo (annual) | 30 video minutes/month, all 140+ languages, brand kit, screen recording |
| Enterprise | Custom | Unlimited minutes, custom avatars, SSO, dedicated support, full compliance stack |
Where most users will land: The Creator tier at $64/mo is the practical sweet spot for small teams — it unlocks all languages, brand kit features, and is realistic for producing 30 minutes of finished video per month. Heavier users move to enterprise.
The free tier is genuinely limited. 3 minutes lifetime (not monthly) is enough to evaluate output quality but not enough to test workflow at any meaningful scale. Synthesia clearly designs the free tier as a sample, not a starter.
Against HeyGen: Synthesia $18/mo Starter vs HeyGen $24/mo Creator. Synthesia wins on lowest entry price; HeyGen wins on minutes ceiling for the price (HeyGen’s credit allocation can buy more video at the same tier if you stick to lower-cost avatar settings). Synthesia wins on budget predictability; HeyGen wins on flexibility.
Score Breakdown
| Factor | Score | Weight | Weighted |
|---|---|---|---|
| Core Performance | 82/100 | 30% | 24.6 |
| Ease of Use | 80/100 | 20% | 16.0 |
| Value for Money | 76/100 | 25% | 19.0 |
| Output Quality | 80/100 | 15% | 12.0 |
| Support & Reliability | 78/100 | 10% | 7.8 |
| Overall | 79/100 | 79.4 |
Core Performance (82/100): 230+ avatars, 140+ languages, mature PowerPoint integration, full team collaboration. The capability set is broad and production-grade. Slightly behind HeyGen on raw avatar realism, but ahead on structured workflow.
Ease of Use (80/100): Modern interface, structured around teams. First-time creators can produce a finished video within 15 minutes of learning. Slight friction for solo users who don’t need the team-workflow features — Synthesia’s UI is designed for organisations, which can feel heavy for one-person production.
Value for Money (76/100): Starter at $18/mo is the lowest entry price in the avatar category, which helps. The minutes-per-month pricing model is more predictable than HeyGen’s credits, which is genuinely valuable for teams forecasting video budgets. Custom avatars being enterprise-only is the clearest negative — HeyGen’s $99/mo self-serve custom tier is more accessible.
Output Quality (80/100): Avatar realism is good but trails HeyGen’s Avatar IV. Lip-sync, gesture, and eye-contact quality are all consistent and professional, but a side-by-side test will typically favour HeyGen for surface realism. For corporate training and internal comms — Synthesia’s primary use case — the gap doesn’t matter. For consumer-facing content where the avatar needs to “feel real”, it might.
Support & Reliability (78/100): Among the strongest in the category. Enterprise tier includes dedicated support and onboarding. Even on Creator and Starter tiers, response times and uptime are consistently rated above competitors. SOC 2 Type II / ISO 27001 / GDPR compliance posture is the most mature in the avatar space.

What We Liked
Predictable minutes-per-month pricing. The single biggest practical advantage. Forecasting how much video your team will produce in a quarter is straightforward — pick the tier with the matching minutes allocation and you’re done. No mental maths around credit consumption per avatar or feature.
Compliance stack that passes enterprise procurement. SOC 2 Type II, ISO 27001, and GDPR compliance is the difference between Synthesia getting through your security review and a competitor getting blocked. For organisations with formal vendor evaluation processes, this is decisive.
Native PowerPoint integration. Importing existing slide decks directly into avatar video is a real productivity unlock for L&D and internal comms teams. No tool here does it better.
Team collaboration is production-grade. Roles, permissions, brand kit management, and review flows are all built in. If multiple people need to produce or approve video, Synthesia is designed for that — most competitors retrofit it.
$18/mo entry point is the lowest in the avatar category. A genuine accessibility win for individuals or small teams wanting to test enterprise-quality avatar video without committing to $24+ tiers.
140+ languages is enterprise-grade coverage. Slightly narrower than HeyGen but still more than enough for the vast majority of multinational use cases.
What We Didn’t Like
Avatar realism trails HeyGen’s Avatar IV. Side-by-side, HeyGen’s 2026 avatars look more lifelike. The gap is narrowing but it’s real, and for consumer-facing content it can matter.
Custom avatars are enterprise-only. HeyGen offers self-serve custom avatars from $99/mo. Synthesia gates this behind a sales call and an enterprise contract. The right model for governance, the wrong model for solo creators.
Free tier is a 3-minute lifetime sample. Not a starter plan in any meaningful sense. Enough to test output quality, not enough to test workflow.
The interface is heavy for solo users. Designed for teams, which is a feature for organisations and a friction point for individual creators. If you’re producing video alone, the team-collaboration layer is unused weight.
Language coverage trails HeyGen. 140+ vs 175+ matters less than you’d think (most teams need a handful of languages, not all of them) but if you genuinely need maximum coverage, HeyGen wins this metric.
Who Is Synthesia Best For?
Enterprise L&D and corporate training teams. Synthesia’s combination of compliance, team workflow, and PowerPoint integration is the strongest fit in the category for internal training video at scale.
Regulated industries — financial services, healthcare, government, pharma. SOC 2 Type II / ISO 27001 / GDPR posture is decisive in vendor selection here.
Multinational marketing teams producing the same content across regions. Synthesia’s localisation workflow and 140+ languages handle this well.
Internal communications teams producing CEO updates, all-hands briefings, and policy explainers. Avatar video at predictable cost, with full compliance, in dozens of languages.
Procurement-conscious organisations that need a vendor whose security questionnaire answers are already prepared. Synthesia’s enterprise readiness is the most mature in the avatar space.
Who should look elsewhere:
– Solo creators or small teams who want self-serve custom avatars at the cheapest price — HeyGen at $99/mo is the better fit
– Consumer-facing content where peak avatar realism is the hero — HeyGen’s Avatar IV will produce a more lifelike result
– Heavy users who want maximum video minutes for the lowest cost — credit-based platforms can be cheaper at scale if you stay on lower-cost avatar settings
– Teams who don’t need any of the team-collaboration or compliance features — you’re paying for capability you won’t use
Synthesia Alternatives Worth Considering
HeyGen — The realism leader. Avatar IV is more lifelike, custom avatars are accessible at $99/mo, and 175+ languages is the widest coverage. Trades enterprise compliance maturity for surface output quality. See our HeyGen review and our upcoming Synthesia vs HeyGen comparison which digs into this choice in detail.
Colossyan — A growing avatar platform with strong team-collaboration features and a focus on training content. Less realistic than HeyGen, narrower language coverage than either Synthesia or HeyGen, but competitive pricing and a sensible workflow for L&D use cases.
Lovo AI — Not an avatar tool, but a voice + video production platform with a built-in editor. Different category, but worth considering if your content is voice-led rather than avatar-led. See our Lovo review.
Runway Gen-4 — General AI video, not avatar-based. Better for creative short-form content, worse for structured talking-head video.
Final Verdict
Synthesia scores 79/100 — second place in the AI Video Tools category behind HeyGen (82/100), and the clear first choice for enterprises, regulated industries, and any team that needs predictable cost, mature compliance, and production-grade collaboration.
The honest framing: HeyGen wins on output quality, Synthesia wins on everything organisations need to actually deploy avatar video at scale. If you’re a solo creator producing social-first content, HeyGen is probably the right call. If you’re a team producing training, internal comms, or multilingual marketing video — and especially if you’re in a regulated industry — Synthesia is the safer, more sustainable pick.
Start with the free tier to evaluate output quality against your real use case. If the avatars meet your bar, the Starter or Creator plan is the easy next step. Enterprise is the path if you need custom avatars, full compliance, or unlimited minutes.
Frequently Asked Questions
Is Synthesia better than HeyGen?
Depends on what you’re optimising for. HeyGen wins on avatar realism (Avatar IV), language coverage (175+ vs 140+), and accessible self-serve custom avatars ($99/mo vs enterprise-only). Synthesia wins on enterprise compliance (SOC 2 Type II, ISO 27001, GDPR), pricing predictability (minutes vs credits), team collaboration features, and PowerPoint integration. Our Synthesia vs HeyGen comparison covers this in detail.
How much does Synthesia cost?
Synthesia’s paid plans start at $18/mo (Starter, 10 video minutes per month, annual billing). Creator is $64/mo for 30 minutes per month and full feature access. Enterprise is custom-priced and unlocks unlimited minutes, custom avatars, SSO, and the full compliance stack.
Does Synthesia have a free plan?
Yes — but only 3 minutes total, lifetime. The free tier is a sample to evaluate output quality, not a starter for ongoing use.
Can I create a custom avatar with Synthesia?
Yes, but only on enterprise tiers. The custom avatar process is managed (typically involving an onboarding session and a higher-fidelity capture process), which suits organisations needing strict governance and consent tracking. For self-serve custom avatars at a fixed price, HeyGen at $99/mo is more accessible.
Is Synthesia GDPR compliant?
Yes — Synthesia is GDPR compliant and also holds SOC 2 Type II and ISO 27001 certifications. Among AI avatar platforms, Synthesia’s compliance stack is the most mature, which is the key reason it wins enterprise procurement battles in regulated industries.
