A HeyGen alternative built for UGC ads
HeyGen is a strong AI avatar platform for talking-head videos, training, and localization. Sepia does something different. It turns a product photo and a short brief into UGC style video ads, served in multiple hooks for creative testing.
Direct comparison
HeyGen vs Sepia
HeyGen is an avatar platform: a presenter says your script to camera, in many languages. Sepia produces a product ad: several shots cut together around the thing you sell, with the product itself held identical throughout.
| Criterion | HeyGen | Sepia |
|---|---|---|
| What the output is | A talking-head video of an avatar delivering a script, strong for training, explainer and localisation. | A finished 9:16 product ad: several shots cut to a voiceover, burned-in subtitles, mastered audio, music bed. |
| Where the product appears | Usually not at all, or as an inserted asset behind the presenter. | The product is the subject. It is shown, held, and kept identical on every frame of every shot. |
| Creative variations | Same script across avatars and languages. | Several ads on the same product, each opening on a different hook, to find the angle that performs. |
| Localisation | A core strength: translation and dubbing across many languages. | Ads are produced per language from the brief, not dubbed after the fact. |
| Pricing model | Monthly subscription tiers with seats and credit allowances. | Pay-as-you-go credits. No subscription, no seat. |
When HeyGen is the better call
If you need a presenter to deliver a script to camera, at scale, in many languages, for training, onboarding, explainer or corporate communication, HeyGen is built for exactly that and Sepia is not a substitute.
When Sepia is the better call
If the goal is to sell a physical product with a vertical ad, where the packaging has to be legible and unchanged and you want several hooks to test, that is a different job and it is the one Sepia does.

Frequently asked questions
How is Sepia different from HeyGen for UGC ads?
HeyGen centers on AI avatars and talking-head video from a script, and serves marketing, training, and localization well. Sepia is focused on UGC style product ads. You give a product photo and a short brief, and you get ad-ready videos in multiple hooks for testing.
Do I need to film anything or hire creators?
No. Sepia runs a full automated pipeline with no shoot, no casting, and no crew. It uses models such as Seedance, Veo, Kling, and ElevenLabs to produce 9:16 videos with subtitles and music, typically within about a day.
