HeyGen vs Synthesia: Which Should You Choose?
$29-$89/month makes HeyGen the avatar platform sales teams actually expense. Personalized outreach is its home turf. Videos cap at 5 min per video, which suits pitch-length content, and a watermarked free tier lets reps prove the concept before any budget conversation.
Synthesia prices at $29-$99/month with no free tier, a structure aimed at corporate training budgets rather than individual experiments. 30 min runtimes handle full HR modules. Training departments amortize that cost across whole course libraries, which is exactly the buyer Synthesia wants.
Avatars are only part of the budget. Vivideo covers the rest — 30+ AI video models including Sora 2, Veo 3.1, and Kling, built-in editing, watermark-free exports, and localization into 30 languages with 200+ AI voices — under one subscription.

Frequently Asked Questions
Is HeyGen or Synthesia better?
Sales organizations doing personalized outreach gravitate to HeyGen; corporate training and HR teams need Synthesia's longer 30 min format. Overlapping $29 entry points make intent, not price, the deciding factor — buy whichever matches the videos you actually ship.
What's the difference between HeyGen and Synthesia?
Their taglines nearly match — AI Avatar Video Platform versus AI Avatar Video Generator — but the builds differ: HeyGen runs $29-$89/month with 5 min per video limits for sales content, while Synthesia runs $29-$99/month and stretches to 30 min for training.
Is HeyGen or Synthesia free?
Only HeyGen offers a free tier, and it watermarks exports; Synthesia has no real free tier at all. Anyone who wants free, clean output before paying should note that Vivideo's free tier ships watermark-free exports with daily generations.
Which is cheaper, HeyGen or Synthesia?
Nominally HeyGen, whose $29-$89/month range tops out below Synthesia's $29-$99/month. Real cost depends on video length: 5 min per video may force workarounds for long training content that Synthesia's 30 min ceiling handles in one render.

Beyond avatars, yes: Vivideo's single subscription spans 30+ AI video models (Sora 2, Veo 3.1, Kling), watermark-free exports, built-in editing, videos up to 10 minutes, and 200+ AI voices localizing content into 30 languages — a wider production toolkit than either avatar specialist.
