About "Synthesia"
What is Synthesia
Synthesia is a business-focused AI video platform that turns text (a script) into studio-quality videos of an AI avatar speaking. Under the tagline "All-in-one AI Video platform for business," you create training, marketing, and sales videos with no camera or crew. Run by Synthesia Ltd (London), it's the industry leader — used by 1M+ people and 50,000+ companies (90% of the Fortune 100).
Synthesia's core is entering a script and having the chosen AI avatar speak it in a video. Beyond stock avatars, you can create personal/brand avatars. It supports 160+ languages and 1,000+ voices, plus templates, PowerPoint import, screen recording, Brand Kits, and auto-captions.
Synthesia goes beyond script-to-avatar into translation, dubbing, and interactivity. It offers AI Dubbing (140+ languages on Enterprise), 1-click video translation (80+ languages), interactive avatars, expressive avatars, Roleplay Sessions for practicing conversations, and the Synthesia 2.0 release. Base model names aren't disclosed; it's described as text-to-video / neural video synthesis.

How it differs from other AI avatar video tools
Synthesia stands out for a business/L&D-first build plus strong multilingual and governance features (SSO/SCORM, etc.). That's a different aim from consumer-friendly ease or photo-to-video tools.
| Aspect | Synthesia | HeyGen | D-ID |
|---|---|---|---|
| Focus | Business avatar video | Avatar video + translation + API | Talking video from a photo |
| Strength | Training, templates, governance | Digital Twin, Avatar V | Easy photo avatars |
| Languages | 160+, translate/dub | 175+, lip-sync | Multi-language |
Alternatives to compare include fellow avatar-video leader HeyGen, D-ID for talking video from a photo, and AI clone video Argil. For businesses that want to mass-produce training and internal/external videos with multilingual and governance built in, Synthesia is a strong choice.
