Visit WebsiteFeature-by-feature
HeyGen leans into realism and creative flexibility. Avatar V delivers identity-consistent avatars trained on your behavior, with a one-shot Video Agent, photo-to-video lip-sync, digital twins via short video, and a Cinematic workflow that can animate stills. Its AI Studio controls tone/gesture/emotion; it also has interactive video with quizzes, SCORM export, and integrations with video-gen models like Sora, Veo, Kling, and Seedance 2.0 — plus a free AI lip-sync generator and a real-estate playbook. Synthesia focuses on enterprise polish: 240+ pre-built avatars, 1000+ voices, AI Screen Recorder with transcript cleanup, AI Dubbing 2.0, motion graphics that now auto-translate, and Roleplay Sessions with scored coaching. It integrates with Slack, Salesforce, Canva, and is testing Gemini Omni Flash for text/image/audio-to-video. Synthesia is stronger on internal workflows; HeyGen on outward-facing content.
Pricing compared
Both are freemium, but Synthesia's free tier is very limited — not for unlimited casual use. HeyGen's free tier is also limited, but it offers a free AI lip-sync tool which could be handy for testing. Full specs aren't listed, but both monetize via subscription tiers that unlock higher resolution (HeyGen offers 4K/1080p export), more avatars, and advanced features like SCORM export or enterprise security. Your choice depends on value: if you need 175+ languages and custom digital twins, HeyGen's premium might justify cost; if you need enterprise compliance and interactive roleplay, Synthesia's value is in its L&D features.
