Synthesia vs HeyGen in 2026: The Comparison Just Flipped

Last updated: June 12, 2026

Answer in 40 words: Synthesia is the better default AI avatar tool for most B2B marketers in 2026. After HeyGen scrapped unlimited plans and Synthesia added custom avatars to its $14/mo plan, the recommendation flipped. HeyGen still wins for short-form social and language reach.

The Short Version

The default recommendation flipped in 2026. After HeyGen scrapped its unlimited plans on May 15 and moved everything to a credit-based system, and Synthesia closed the avatar quality gap with Express-2 while putting custom personal avatars into its $14/mo annual Starter plan, the math now favors Synthesia for most B2B founders and lean marketing teams. HeyGen is still the better pick for short-form social, voice cloning, and the widest language reach. But for most people producing weekly content with their own custom avatar, Synthesia is now the better choice. I just demoed it. The custom avatar from your own uploaded video is impressively realistic. If you want the broader category context first, I cover the full landscape in best AI video generator for marketing.

This is a meaningful shift. Most comparison articles still default to the 2024 narrative (“HeyGen for marketing, Synthesia for enterprise”). That framing is now stale. The real story is that Synthesia caught up on quality, undercut on price, and made its best feature accessible at the entry tier, while HeyGen restructured pricing in a way that surprised a lot of paying users.

What changed for HeyGen and Synthesia in 2026?

Synthesia and HeyGen are the two most-used AI avatar video platforms in B2B marketing. Both turn a script into a presenter-led video without filming, voice talent, or studio equipment. Synthesia is built around enterprise training and structured production. HeyGen is built around marketing velocity and creator workflows. Both shifted significantly in 2026. Here’s what changed in the last 6 months that most comparison pages haven’t updated yet.

HeyGen scrapped unlimited plans (May 15, 2026). HeyGen’s own help center confirms it. The old “unlimited Avatar III + 200 Premium Credits” structure is gone for new customers. New plans are fully credit-based: Creator gives you 600 credits, Pro gives 1,000, Business gives 1,500. Credits now roll over month to month, which is a real improvement. But every feature now consumes credits, so the practical output is much tighter than the old “unlimited” framing suggested.

Synthesia 3.0 closed the avatar gap (October 2025). Synthesia launched Express-2 avatars with full-body movement, natural hand gestures, micro-expressions, and no length cap at 1080p/30fps. Independent testing by DesignRevision still scores HeyGen Avatar IV slightly higher on raw expressiveness (9.2/10 vs Express-2 around 8.2/10), but the gap is narrow enough that most viewers can’t tell.

Synthesia put custom avatars in Starter (2026). Personal Avatars (digital twins built from a short video upload) are now included in annual Starter ($14/mo) and Creator plans. This used to be an Enterprise-only feature or a $1,000/year add-on. That’s the single biggest price-to-value change in the category this year.

Synthesia added AI Playground across all plans (2026). Veo 3.1, Veo 3.1 Fast, and Sora 2 are now embedded directly inside the Synthesia editor for B-roll generation. Even on the free plan. HeyGen has no equivalent.

Synthesia dropped prices (early 2026). Starter went from $19/mo to $14/mo billed yearly. Creator went from $89/mo to $59/mo billed yearly, according to Synthesia’s current pricing page. HeyGen prices stayed flat but the credit-only model effectively makes the platform more expensive in practice.

Synthesia vs HeyGen at a glance

How did HeyGen’s pricing change in May 2026?

This is the part most comparison articles haven’t updated yet, but it’s the biggest change in the category this year.

Before May 15, 2026, HeyGen Creator at $29/mo gave you unlimited Avatar III videos plus 200 Premium Credits for Avatar IV. The 200-credit cap was confusing, but base videos were genuinely unlimited.

After May 15, HeyGen retired that structure. The new Creator plan still costs $29/mo, but now you get 600 credits, and everything counts against them. Standard videos. Avatar IV videos. Video translation. B-roll generation. Add motion. Voice training. All of it.

In practice, the $29 plan now produces roughly 4 short videos per month if you’re using premium features, voice cloning, and B-roll. Not the “unlimited” output the old marketing implied. The credits do roll over now, which is a real improvement. But active producers are running out faster than the old plan, and the path to more output is upgrading to Pro at $49/mo (1,000 credits) or Business at $149/mo (1,500 credits).

For comparison, a creator on Synthesia Starter at $14/mo annual gets 14,500 credits per year, which works out to roughly 120 minutes of video. That’s a meaningful difference at the entry tier.

One independent test by blogrecode ran the same 25 videos through both platforms and reported $95 on Synthesia versus $384 on HeyGen. Real-world cost difference, not just sticker price.

Did Synthesia close the avatar quality gap with HeyGen?

I demoed Synthesia recently after hearing about Express-2 from a few colleagues. The custom personal avatar, where you upload a short video of yourself, is genuinely impressive. The lip-sync holds, the gestures feel natural, the expression range is wider than the old Synthesia avatars. It’s not perfect, but it’s close enough that most viewers wouldn’t flag it.

HeyGen Avatar IV is still the slightly more expressive option for short-form, viewer-facing content. The micro-expressions and head tilts are tighter. The DesignRevision head-to-head put HeyGen at 9.2/10 versus Synthesia at 8.2/10 on raw avatar quality. If you’re putting an AI presenter on your YouTube channel and you need it to look as real as possible, HeyGen edges out.

For everything else, the difference no longer matters as much as it did a year ago. Synthesia Express-2 looks good enough for client outreach, sales videos, training content, internal comms, and most B2B marketing use cases. The “Synthesia avatars feel corporate and stiff” criticism from older reviews is now mostly outdated.

If you want to see what either avatar looks like when it’s built from your own video, I walked through the process in how to clone yourself with AI.

Which platform has better custom personal avatars?

This is the part of the demo that sold me.

Synthesia now lets you upload a short video of yourself and create a custom personal avatar inside the annual Starter plan at $14/mo. Used to be Enterprise-only, then a $1,000/year add-on. Now it’s at the entry tier, per Synthesia’s pricing structure.

The processing takes up to 10 days, but the output is impressive. The avatar moves like you. The voice clones from the same recording session. You can use it in any of Synthesia’s 160+ supported languages with frame-accurate lip-sync.

HeyGen also offers a custom avatar (called a Digital Twin) on its free plan, and the voice cloning is faster (15-30 second sample versus Synthesia’s longer enrollment). But the catch is that using your Digital Twin in actual production burns credits like everything else, so the per-video cost adds up fast.

For someone making a few founder videos per month, your own face on screen, multilingual reach, Synthesia at $14/mo is now the cheapest legitimate path in the category. That wasn’t true 6 months ago.

Which has better video translation and language support?

HeyGen still has the edge here, even with everything else shifting.

175+ languages with one-click video translation that preserves the original voice. Voice cloning that works from a 15-30 second sample. Translation included across all paid plans, not gated behind enterprise pricing.

Synthesia has 160+ languages for narration and 80+ for AI Dubbing on uploaded video. The dubbing now starts on Starter, which is a real upgrade from when it was Enterprise-only. But HeyGen’s language breadth and the cleaner translation workflow still come out ahead.

One gotcha worth flagging on HeyGen: the “unlimited” translation framing has a 120 minute per month cap in practice. Multiple users on Trustpilot reported being surprised by this after annual signup. Read the fine print on either platform before committing if translation volume is your primary use case.

When should you still pick HeyGen?

I want to be clear: HeyGen is still a great product. The 4.8/5 G2 rating is real. The Avatar IV quality is real. The use cases where I’d still pick HeyGen first:

• High-volume short-form social content. If you’re making 20+ short videos a month for LinkedIn, TikTok, Instagram, HeyGen’s expressiveness reads better.
• Voice cloning speed. 15-30 second sample beats Synthesia’s longer enrollment.
• Maximum language reach. 175+ versus 160+ matters if you’re localizing across uncommon markets.
• Photo avatars and face swap. Niche but useful for testimonials and personalization.
• Avatar IV for sales outreach. When the realism difference actually changes reply rates.

If you’re not doing weekly Avatar IV production, the credit math on HeyGen Creator is still workable. It just needs more attention than it used to. Start a HeyGen free trial to see if it fits your workflow.

What are Synthesia’s biggest weaknesses?

Two areas where Synthesia falls short:

• Avatar customization on lower tiers. Outfit changes, advanced gestures, and brand kit features stay locked behind Creator and Enterprise. If you want full visual control without going up the price ladder, this hurts.
• Content moderation is strict. Multiple reviewers on Product Hunt reported account bans for legitimate use cases. Synthesia’s stance on synthetic media misuse is appropriately careful but can frustrate users producing edge-case content.

And the universal limit on both: neither is built for product demos. If your video job is showing software, screen capture beats AI avatars every time.

Which is more secure for enterprise procurement?

If you’re inside a procurement cycle, this matters.

Synthesia: SOC 2 Type II, ISO 27001, ISO 42001, GDPR. AES-256 encryption. The deepest compliance stack in the category. Used by over 60% of the Fortune 100.

HeyGen: SOC 2, GDPR. Sufficient for most B2B marketing use cases but lighter on the enterprise certification side.

Neither has HIPAA compliance. If you’re processing PHI, don’t treat either as HIPAA-compliant without a signed BAA.

Which one should you actually pick?

For 9 out of 10 B2B clients I work with, I’d now recommend Synthesia as the default.

The reasoning:

The custom personal avatar at $14/mo entry tier is genuinely the best price-to-output ratio in the category right now. Express-2 quality is good enough for client outreach, founder content, sales videos, training, and most B2B marketing use cases. The 120 minutes per year on Starter covers the actual production volume of most lean teams. AI Playground gives you Veo 3.1 and Sora 2 for B-roll without a separate subscription. And the compliance stack clears procurement faster.

I’d still pick HeyGen for two specific use cases:

1. High-volume short-form video for social. If you’re making 4+ videos a week for LinkedIn or TikTok, HeyGen Pro at $49/mo with 1,000 credits and 4K export still produces output that beats Synthesia for short-form expressiveness.
2. Maximum language reach and personalized sales outreach. 175+ languages and faster voice cloning give it the edge for global localization or AI-personalized prospecting.

For everyone else, Synthesia is the better bet now. That’s a meaningful flip from what I would have said 6 months ago. The broader AI video category is growing fast too. Fortune Business Insights projects the market to reach $3.35 billion by 2034 at an 18.8% CAGR, which means both platforms have reason to keep iterating.

The Bottom Line

I changed my mind on this one.

For most of 2024 and 2025, I would have recommended HeyGen as the default AI video tool for B2B marketing teams. The avatars looked better, the unlimited Avatar III plan was genuinely useful, and the language reach was unmatched.

In 2026, the picture flipped. Synthesia closed most of the quality gap with Express-2. It dropped prices. It put custom personal avatars into the $14/mo annual Starter tier, which is the single best price-to-value move anyone in the category has made this year. And HeyGen scrapped its unlimited plans on May 15, leaving paying users with a credit-based system that’s tighter than what they signed up for.

For most B2B founders, fractional CMOs, sales teams, and lean marketing departments, Synthesia is now the better default. Try the free plan to see the avatar quality. If you want a custom avatar that looks like you, go to annual Starter at $14/mo.

If you’re producing high-volume short-form video, need maximum language reach, or run personalized sales outreach across markets, HeyGen is still worth keeping in the stack. Just go in with clear eyes on the new credit math.

AI avatars are not the whole answer. They belong inside a real content workflow for B2B marketing alongside screen capture, real-you-on-camera founder content, and proper distribution. The platform is one piece. The system is what makes it work.

Pick the tool that fits the actual job. Test before you commit. And reassess every 6 months, because in this category, the answer keeps changing.
