HeyGen vs Synthesia
HeyGen and Synthesia are two of the best known avatar video studios, and they solve the same basic problem: turn a script into a presenter led video without a camera or a studio. The difference is where each one has invested. HeyGen leans toward creators and marketing teams, with 500+ stock avatars listed even on its free tier, custom digital twins trained on your own footage, voice cloning from the Creator plan and video translation across 175+ languages claimed. Synthesia leans toward large organizations, with 240+ stock avatars and 1,000+ voices across 160+ languages claimed, wrapped in the things learning teams ask for: brand kits, version control, interactive quizzes, CTAs and branching, SCORM export and direct connectors to Docebo, Moodle, SAP Litmos, Articulate 360 and TalentLMS. Both sell credits rather than minutes, both publish a free tier, and both cap their mid tiers at roughly 30 minutes of video a month before the next step up. Neither product sends outreach, carries a contact list or books meetings, so both sit upstream of whatever delivers the video. Prices below come from their published pricing pages, August 2026.
Both produce the same class of video, so the choice is about what surrounds it: HeyGen is the easier place to start for marketing, creator and localization work, while Synthesia is built for training and communications teams that need governance, LMS delivery and procurement paperwork.
Pick HeyGen if
- You want the widest choice of ready made presenters, with 500+ stock avatars listed on their free tier and voice cloning from the $29 Creator plan (from their published pricing, August 2026).
- Translation is the job. HeyGen publishes 175+ languages on paid tiers, the capability its own materials lead with.
- You want to generate video programmatically without an enterprise contract. Their public API is self serve and billed pay as you go from $5, separately from the subscription plans.
- You need 4K export at a mid tier price, which their $49 Pro plan lists alongside 1,000 monthly credits.
Pick Synthesia if
- The video is going into a learning platform. SCORM export plus direct connectors for Docebo, Moodle, SAP Litmos, Articulate 360 and TalentLMS make Synthesia the shorter path.
- You need interactivity and measurement, such as quizzes, CTAs and branching scenarios, with reporting on views, watch time, engagement and clicks.
- Procurement asks for ISO 42001 alongside SOC 2 Type II and GDPR, all three of which Synthesia claims.
- Localization runs across many markets and you want 1-click translation into 80+ languages with a multilingual player that plays in the viewer's language, both listed on their Enterprise tier.

HeyGen pros
- 500+ stock avatars listed on Free, with larger libraries on paid tiers
- Custom digital twins trained on your own footage, plus voice cloning from the Creator tier
- Video translation across 175+ languages, their strongest single capability
- A free tier with 3 videos a month makes evaluation free
- Team collaboration, SAML/SSO and LMS integrations on Business
HeyGen cons
- Credit consumption varies by model, so the video volume a plan actually buys is hard to read from the plan name (their pricing page)
- Creator's 600 credits work out to roughly 30 minutes of video a month (their pricing page)
- Business is $149 per month plus $20 per extra seat, so team cost climbs with headcount (their pricing page)
- No sequencer, no contact database, no native LinkedIn or email delivery and no booking page, so outbound needs a separate stack (their site)
Synthesia pros
- 240+ stock AI avatars and 1,000+ voices across 160+ languages claimed
- Personal avatars that clone face and voice, plus AI dubbing with lip sync and 1-click translation into 80+ languages
- SOC 2 Type II, ISO 42001 and GDPR compliance claimed, which clears most enterprise procurement
- Deep learning-platform integration surface with Docebo, Moodle, SAP Litmos, Articulate 360 and TalentLMS, plus SCORM export
- Analytics on views, watch time, engagement and clicks, with interactive quizzes, CTAs and branching
Synthesia cons
- Credit and minute caps bite quickly: about 10 minutes of video per month on Starter and 30 on Creator before volume moves to quoted Enterprise pricing
- Built for training, communications and marketing content rather than per-lead prospecting, with no prospect list, no sending layer and no booking step
- Per-recipient personalization requires building against the API with template variables rather than a campaign interface
- Personal avatar creation requires explicit consent and a screening process before the avatar can be used
It depends on how much video you make. From their published pricing in August 2026, Synthesia Starter is $18 per month billed yearly, or $29 billed monthly, for about 10 minutes of video a month, while HeyGen Creator is $24 per month billed annually, or $29 monthly, for 600 credits worth roughly 30 minutes. Higher up, HeyGen Pro is $49 per month for 1,000 credits and Synthesia Creator is $64 per month billed yearly, or $89 monthly, for about 30 minutes. HeyGen also notes that credit consumption varies by model, so read their credit table before estimating monthly minutes. Both publish a free tier, and both route high volume to a quoted Enterprise plan.
Neither one sends anything. Both are production tools with no prospect list, no email or LinkedIn sending layer and no booking step. Synthesia can render many videos from a template using variables through its API, with a callback ID to tie each render back to a recipient, and HeyGen supports batch generation through its public API. In both cases the delivery has to be handled by a separate tool.
Both figures are vendor claims and they are close. HeyGen publishes 175+ languages on paid tiers and 30+ on Free. Synthesia claims 1,000+ AI voices across 160+ languages, plus AI dubbing with lip sync and 1-click translation into 80+ languages with a multilingual player, with the 1-click translation listed on its Enterprise tier.
Yes. HeyGen trains custom digital twins from your own footage, with 1 on the free plan and 5 on Business, and voice cloning from the Creator tier. Synthesia creates personal avatars that clone face and voice, with 3 on Starter, 5 on Creator and unlimited on Enterprise. Synthesia also requires explicit consent and states that new users and content are screened before an avatar can be used, which buyers report adds lead time before a custom avatar is usable.
One of these tools is ours.
Weezly is in this directory too: LinkedIn outreach with AI clone videos, a 300M+ leads database and booking, from $59 per month. See if it earns a spot in your stack.
