HeyGen vs Synthesia
An independent comparison of two tools we do not make.
Both are corporate video tools and both start at $29 a month. HeyGen has the bigger library at 700+ avatars and bills on credits plus enterprise tiers. Synthesia has 230+ studio presenters, bills per seat, and is built around a scene-by-scene editor for training and L&D. Neither targets creator-style social ads.
HeyGen and Synthesia are the two names that come up most often for AI presenter video, and they overlap heavily: polished avatars, scripted scenes, and an editor rather than a one-shot generator. The differences that actually change the decision are library size, how you are billed, and how your team works.

What each one is built for
HeyGen is aimed at corporate training, internal comms, and presentations. Synthesia is aimed at corporate training, L&D, and internal video. In practice that means both produce polished, narrated, landscape-first output rather than casual vertical footage.
Avatars
HeyGen lists 700+ avatars, the largest library of the two by a wide margin. Synthesia lists 230+ studio presenters. Style is closer than the numbers suggest: both render presenters that read as studio talent, not as someone filming on a phone.
Pricing model: credits versus seats
Both open at $29 a month, and both entry tiers are tightly limited. Above that they diverge. HeyGen scales with credits and enterprise tiers, with a heavier month landing around $180 to $270. Synthesia scales per seat, and higher volume moves you into a custom enterprise tier.
That difference decides more than the sticker price. Credits punish volume; seats punish headcount. One editor producing a lot of video is usually cheaper on seats, and a whole department producing occasionally is usually cheaper on credits.
Workflow
HeyGen uses a studio-style editor. Synthesia uses a scene-by-scene editor. Both expect you to build a video from scenes rather than type one prompt, which is the right shape for a structured training module and the wrong shape for testing twenty hooks in an afternoon.
Which should you pick?
Choose HeyGen if
You need the widest avatar selection, you are producing presentations and internal comms rather than long courses, and credit billing suits a small number of heavy producers.
Choose Synthesia if
You are producing training and L&D at scale across a team, you want a structured scene editor, and per-seat billing is easier to get approved than variable credit spend.

Where UGC Vids AI fits, and where it does not
This page is published by UGC Vids AI, so read the rest of it with that in mind. We are not on the comparison above because we are not the answer to every version of this question. We build one narrow thing: 9:16 UGC-style video ads for ecommerce brands and agencies.
Two differences are worth knowing about if you are shopping this category. First, one credit pool covers every model, so you pick the model per ad rather than per plan: Veo 3.1, Sora 2 and Sora 2 Pro, Kling, Seedance, OmniHuman 1.5, Grok, and Happy Horse 1.1. Second, the plans are credit-metered with no video-count cap: Starter $49 a month for 5,000 credits, Growth $99 for 12,000, Agency $199 for 25,000, 30% off annual, and credits never expire. Top-ups run $10 to $140 when a month runs hot.
Where the tools above are the better call:
- HeyGen is the better fit for corporate training, internal comms, presentations.
- Synthesia is the better fit for corporate training, L&D, internal video.
