Synthesia
Enterprise-grade AI avatar video — the polished, expensive HeyGen
Overview
Synthesia is the AI avatar platform that 50% of the Fortune 100 use for internal training videos, product explainers, and localized marketing content. It produces meaningfully more polished output than HeyGen — avatar movements are smoother, voices are less robotic, and the rendering pipeline is more reliable for long-form content. The catch is the price: Synthesia starts at $29/month for Starter (10 minutes of video) but most teams running real volume land on Creator at $89/month or Enterprise (custom, typically $1,000+/month).
Synthesia also leads HeyGen on enterprise features like SSO, audit logs, custom avatar training with consent workflows, and SOC 2 Type II compliance — features that matter for L&D teams at large companies but are overkill for marketing-led use cases. The trade-off vs. HeyGen comes down to use case: HeyGen wins on API-first programmatic generation, lower per-video cost at scale, and 175+ language support.
Synthesia wins on raw avatar quality, enterprise compliance, and the safer brand for buyer committees. For enterprise L&D teams, internal comms, and brands with budget for premium video, Synthesia is the right choice.

Frequently asked questions
