Synthesia vs HeyGen: The Same Format, Different Strengths

Synthesia and HeyGen are the two leading AI avatar video platforms. They share the same core product: you type a script, choose an avatar, and the avatar lip-syncs your text in a professional-looking video.

Where they differ:

  • Synthesia prioritizes scale, diversity, and L&D workflows, 230+ avatars, 140+ languages, SCORM export, LMS integration
  • HeyGen prioritizes realism and translation, best-in-class lip sync, 40+ language video translation, more modern visual aesthetic

For buyers, the choice between them usually comes down to: Do you need maximum language support and avatar variety? (Synthesia) Or do you need the most realistic avatar and video translation? (HeyGen)

Synthesia wins on language count, avatar variety, screen recording, and L&D integrations. HeyGen wins on avatar realism, lip sync, and video translation.

Pricing Comparison: Synthesia vs HeyGen

Synthesia:

  • Starter: $22/mo (10 videos/month)
  • Creator: $67/mo (30 videos/month)

HeyGen:

  • Creator: $29/mo (~7-15 videos/month depending on length)
  • Business: $89/mo (~15-30 videos/month)

At entry level, Synthesia Starter ($22) is cheaper than HeyGen Creator ($29). But Synthesia gives you 10 complete videos while HeyGen gives you 15 minutes, for short 30-60 second videos, HeyGen may deliver more content per dollar at entry level.

For both tools: the per-video cost is $2-4, which is 4-8x more expensive than non-avatar AI video tools. FluxNote at $10/mo for 21 videos = $0.48/video.

Which Should You Choose?

Choose Synthesia if:

  • You need 100+ language support for global training rollouts
  • You want the widest avatar diversity across a large content library
  • You need screen recording integration for software training
  • You're building SCORM-compatible content for LMS platforms
  • Your primary use is internal L&D content

Choose HeyGen if:

  • You need the most realistic avatar lip sync for public-facing video
  • You want to dub existing video footage into other languages
  • You prefer a modern visual aesthetic over corporate template styling
  • You're building a personal brand avatar for YouTube or LinkedIn

Choose neither if:

  • You're creating social media content (TikTok, YouTube Shorts, Instagram Reels)
  • You need stock footage-based video instead of talking heads
  • You need animated captions (15+ styles), trending audio, or high-volume output at low cost

For social media creators, FluxNote at $10/mo covers the footage-based, caption-rich, high-volume workflow that neither Synthesia nor HeyGen is designed for.
