HeyGen Review (2026)

HeyGen turns a script into a video of a talking AI avatar — a stock avatar, or a custom clone of a real person — dubbed into 175+ languages with matching lip sync. It's become a default pick for training videos, product explainers, and localized marketing where filming a human on camera for every version isn't practical.

Updated September 1, 2026: this page reflects the current model lineup, including GPT-5.6 (flagship Sol, mid-tier Terra, budget Luna) and Claude Fable 5.1 (new flagship, alongside Opus 4.8).

What HeyGen actually is

You write or paste a script, pick an avatar (500+ stock options, or a custom-trained clone of yourself or a colleague), choose a voice, and HeyGen renders a video of that avatar speaking the script with synced lip movement. The translation feature takes an existing video and redubs it into another language while keeping lip sync intact, which is the feature most customers actually build workflows around — one recorded video becomes 20+ localized versions without reshooting.

It's positioned squarely at business use: training and onboarding videos, product walkthroughs, localized ad creative, and interactive video for sales enablement. It is not a general video-generation model like Sora or Runway — there's no text-to-scene generation, just avatar-driven talking-head content.

Pricing as of September 2026

Credits are the real cost driver: premium avatar rendering runs roughly 20 credits per minute, so Creator's 600 monthly credits go faster than the sticker price suggests once you're producing regularly.

What HeyGen does well

Translation and redub quality

Feeding in one recorded video and getting back a lip-synced version in another language is the standout feature, and it works well enough to be the core of most customers' workflow.

Custom avatar realism

Custom-trained avatars from a short reference video hold up well across longer scripts, without the uncanny drift some earlier avatar tools showed.

Language coverage

175+ languages and dialects on paid plans covers essentially any localization need a business will have.

What HeyGen doesn't do well

Credit math is easy to underestimate

Regular use of premium avatars or longer videos burns through monthly credits faster than the plan price implies; budget for add-on credit packs if you're producing at volume.

Not a general video generator

If you need scene generation, b-roll, or anything beyond a talking avatar, you need a different tool entirely — HeyGen doesn't compete with Sora or Runway on that front.

Business tier pricing scales with seats

The $149 + $20/seat Business plan adds up quickly for larger teams compared to the flat per-user pricing some competitors use.

Who should use HeyGen

Companies localizing training or marketing video: Yes. The redub-with-lip-sync workflow is the strongest reason to pick HeyGen specifically.

Solo creators needing occasional talking-head clips: Creator tier works, but watch the credit consumption if you're using premium avatars regularly.

Anyone needing generative b-roll or scene video: Look elsewhere — Runway or Sora fit that need, not HeyGen.

Bottom line

HeyGen is the strongest tool available for avatar-driven, multi-language video at scale, and the translation/redub feature alone justifies it for companies localizing content. Just budget credits realistically — the plan price is not the full story.
