Visit Synthesia →About Synthesia
Synthesia is a browser-based tool for creating videos from a written script. You pick an avatar, type or paste your text, choose a voice, and the platform renders a presenter-style video without cameras, actors or studio time. It is used mainly for training material, product explainers, internal communications and localized marketing.
The current version is Synthesia 3.0, built around the Express-2 avatar engine (Expressive Model 4.0). This is a diffusion-transformer model that generates full-body avatars with natural hand and body movement rather than static talking heads. Version 3.0 also added Veo 3 integration for AI-generated B-roll, interactive Video Agents, Express-Voice instant voice cloning, and enhanced AI Dubbing with frame-accurate lip sync.
The avatar catalog has grown to 180+ stock avatars on the Creator plan and up to 240+ on Enterprise. Personal avatars can now be created from a single image, and lower tiers include a smaller but still usable set of presenters and voices in over 140 languages.
Pricing is tiered. The free Basic plan costs $0/mo and gives you 10 minutes of video per month, 9 AI avatars and 3 personal avatars, with a watermark. Starter is $29/mo monthly or $18/mo billed annually (10 min/mo, 125+ avatars, 3 personal avatars, logo removal, downloads, AI Dubbing). Creator, the most popular plan, is $89/mo monthly or $64/mo annually (30 min/mo, 180+ avatars, 5 personal avatars, API access, interactive videos). Enterprise is custom-priced with unlimited minutes, 240+ avatars, unlimited personal avatars, SAML/SSO and SCORM export. Synthesia recently cut its prices, with Starter down roughly 38%.
The main limitations are the monthly minute caps, which are tight on lower plans, and the fact that avatar-led video suits explanatory content far better than cinematic or emotionally nuanced storytelling. Rendering and editing quirks still occur, and the most advanced features sit behind Creator and Enterprise.
Synthesia is a strong fit for L&D teams, HR, product marketing and anyone who needs to produce or localize a high volume of talking-head videos quickly and without a film crew. It is less suited to creators chasing highly produced, cinematic output.
