What Each Tool Actually Does
Both HeyGen and Synthesia create videos using AI avatars — but the similarity mostly ends there. They've evolved into platforms targeting fundamentally different workflows and audiences.
HeyGen — The content creator's tool
HeyGen built its platform around video translation and dubbing — their translate tool gets 8 million monthly searches and is by far their most-used feature. You upload a video in any language, HeyGen translates it and re-syncs the avatar's lip movements to match the new audio. For creators distributing content across multiple languages, this alone justifies the subscription.
Beyond translation, HeyGen focuses on social and creator content: AI influencer generation, face swap video, talking photo tools, and avatar creation from your own image. The platform leans toward speed and social-first formats.
Synthesia — The corporate training tool
Synthesia built its platform around professional business video — onboarding content, corporate training, eLearning modules, and multilingual internal communications. Their 125+ stock avatars cover diverse demographics and professional styles. Their PowerPoint-to-video workflow lets you import an existing presentation and layer an AI presenter on top, which is a direct differentiator in the enterprise market.
The Creator plan ($89/mo monthly, $59/mo annual) adds 5 Personal Avatars, AI Dubbing, branded video pages, and API access. AI Dubbing is also available on the Starter plan. Synthesia's audience is companies, L&D teams, and educators — not individual creators.

Video Translation: HeyGen vs Synthesia
Video translation is where the gap between these two tools is widest. HeyGen built their entire platform around it — their translate tool handles 8+ million monthly searches and supports 40+ languages with lip-sync dubbing that matches mouth movements to the translated audio. For any creator distributing content internationally, HeyGen is the clear choice.
Synthesia offers video translation in 30+ languages, but AI Dubbing is available from the Starter plan ($19/mo monthly, $14/mo annual). For individual creators or small teams, this pricing makes HeyGen the more accessible option for translation specifically.
AI Avatars: HeyGen vs Synthesia
Both tools offer AI avatar presenters, but their approaches differ significantly.
Synthesia's stock avatar library is broader — 125+ professionally designed avatars covering diverse ethnicities, ages, and presentation styles. For corporate training where representation matters, Synthesia's depth is a genuine advantage.
HeyGen's custom avatar is more accessible — you can create a Custom Digital Twin (your face, your voice) from the Creator plan at $29/month. Synthesia's Personal Avatars (your face) require the Creator plan at $89/month monthly or $59/month annual.
HeyGen also offers the AI Influencer Generator — a tool that creates entirely fictional AI avatar personalities from scratch, which has no equivalent in Synthesia.
Other Alternatives to Consider
If neither HeyGen nor Synthesia feels like the right fit, these tools serve adjacent use cases:
- Revid AI — Best for faceless YouTube channels, music videos, and brainrot content. Script-to-video pipeline with 151 templates. From $39/month.
- Vsub.io — Faceless YouTube video creator with good voiceover quality. Better for long-form content than HeyGen or Synthesia.
- OpenArt — Character consistency tools and Seedance AI video generation. Best if you need to control visual identity across clips.
- ElevenLabs — If voiceover is the priority over avatar presentation, ElevenLabs' voice cloning is superior to either tool's built-in voice.
