What it is and who it's for
Synthesia is an enterprise platform for video with AI avatars in 160+ languages: training, how-tos, onboarding and presentations generated from text. Built for L&D, HR and internal comms at large companies that need scale, brand control and security. What sets it apart is enterprise maturity: SSO, team workspaces, compliance and the widest language coverage around.
Key features
- 230+ avatars and 160+ languages/accents; custom branded avatars.
- Script → video in an editor with slides, PowerPoint-style.
- Team collaboration, templates, brand kit, access control.
- Update a video by changing the text (no re-recording).
- Enterprise security: SSO, SOC 2, user management.
- Built-in voiceover and subtitles.
Get started in 5 minutes
- Sign up at synthesia.io (there's a free trial mode).
- Pick a template, drop your text onto the slides, choose an avatar and language.
- Hit Generate and you have a finished video; edits are just text edits.
When to pick it, when not to
- ✅ Pick it if you need corporate-scale training video, lots of languages, branding and security.
- ✅ Pick it if the content changes often and you need to edit without re-recording.
- ❌ Skip it → go with "HeyGen" if you want a quick clone of yourself and fast translation of social clips.
- ❌ Skip it → go with "Gamma" if what you actually need is a deck or a document, not a talking avatar.
The honest price
Limited free mode; paid plans priced by video minutes and team seats; Enterprise is custom. Exact numbers are on the vendor's site and do change.
Gotchas
- It's built around "talking head + slides" — this is not cinematic video.
- Minutes are capped; high-volume production hits the quota or plan ceiling fast.
- Custom avatars and some languages are on higher tiers.
- Gestures and facial expressions are limited — weaker than live footage for emotional sales videos.
