HeyGen vs Synthesia
Features, pricing, strengths and trade-offs — and which one fits your situation.
The verdict
Editor’s verdict
Both generate presenter videos from a script with AI avatars, but Synthesia is built around enterprise training and governance while HeyGen leans toward marketing, sales and creator content. Choose Synthesia if you run an L&D or internal comms program that needs SCORM export, interactive courses, LMS connections, strict security certifications and consistent output across large teams. Choose HeyGen if you want highly expressive avatars and digital twins, video translation with lip sync in more languages, 4K export on mid-tier plans, and automation through integrations such as HubSpot, Salesforce and Zapier for personalized outreach. HeyGen's individual plans make it easier for solo creators to start, while Synthesia's most important enterprise features, including brand kits and SCORM, sit on its top tier. Both have free plans with watermarks, so testing each with the same script is the fastest way to judge avatar quality for your audience. Neither is the right choice if you mainly edit footage you filmed yourself; an editor like Descript, CapCut or VEED fits that better.
Both HeyGen and Synthesia offer a free plan, so you can try each before paying.
