Synthesia

160+ language support with one-click translation

Synthesia supports 160+ languages and voices with one-click translation into 80+ languages, AI dubbing that preserves lip-sync, and a multilingual video player that auto-selects the viewer's language. Personal avatars speak 30+ languages with voice cloning. Why it matters: Global organisations can produce a single master video and distribute localised versions without separate production workflows or voice actors per language.

Express-2 avatars with full-body gestures and Veo 3 B-roll

Express-2 avatars gesture like professional speakers with natural hand movements, full facial expressions, and accurate lip-sync. Veo 3 integration adds prompt-based B-roll, allowing avatars to demonstrate specific actions in any setting. Why it matters: Training and marketing videos with natural avatar behaviour are more engaging than static talking-head output, reducing the production quality gap between AI and traditional video.

Video Agents for real-time conversational video

Video Agents enable two-way real-time conversations within a video. An AI avatar talks, listens, and responds with business-specific knowledge, captures data in real time, and feeds it into connected systems. Supports training simulations, candidate screening, and guided workflows. Why it matters: This moves Synthesia from a content creation platform to an interactive training and assessment platform. No direct equivalent exists in competing avatar tools.

Desktop-only platform

Synthesia is available on desktop web only. Mobile users are limited to booking demos or testing the free video generator. No iOS or Android app exists. Impact: Teams where stakeholders review or approve content from mobile devices, or creators working away from desktops, face a constrained workflow.

Content moderation queue on all non-Enterprise plans

All videos pass through a content moderation process before finalisation. Priority moderation is reserved for Enterprise customers. Non-Enterprise users on time-sensitive projects may face delays between generation and delivery. Impact: Marketing and communications teams with tight publishing windows may find the moderation queue disruptive, particularly at Starter and Creator tiers.

Video minute allocations are tight below Enterprise

Free plan gives 10 minutes/month. Starter gives 120 minutes/year. Creator gives 360 minutes/year. Advanced features including AI dubbing, voice cloning, and customisable avatars require higher tiers or paid add-ons. Unused minutes do not carry over. Impact: Teams producing content at volume below Enterprise tier will hit limits quickly. The annual model means unused capacity in quiet periods is lost.
