What Synthesia is
Synthesia turns a written script into a video of a presenter speaking it. No camera, no studio, no talent booking. You pick an avatar, paste the text, and it produces a finished video.
Its natural home is corporate training and e-learning, and that focus shows in everything from the avatar style to the SCORM export.
Plans and pricing
| Plan | Price | What’s included |
|---|---|---|
| Free | $0 | 10 minutes of video a month, 9 avatars, watermarked |
| Starter | from $18/mo yearly, $29/mo monthly | No watermark, 125+ avatars, personal avatars included |
| Creator | from $64/mo yearly, $89/mo monthly | 180+ avatars, 5 personal avatars, API access |
| Enterprise | Custom, typically thousands per year | 240+ avatars, unlimited personal avatars, SSO/SAML, SCORM/LMS |
The free plan is a real trial rather than a demo: ten minutes a month is enough to produce a complete short video and judge whether the avatars work for your audience, watermark aside.
The feature that sells it: edit the script, not the video
This is what people underestimate. With a filmed video, changing one sentence means rebooking the talent and reshooting. With Synthesia you edit the line and regenerate.
For training material that goes stale - product names, prices, policies, compliance rules - this changes the economics completely. The value is not that the first video is cheaper. It is that the tenth revision is free.
Cross-lingual voice cloning
Clone a voice and Synthesia can have it speak languages the person does not speak. For a company producing the same onboarding video for offices in six countries, this collapses a genuinely expensive process into one script and six renders.
Synthesia vs HeyGen vs Descript
| Synthesia | HeyGen | Descript | |
|---|---|---|---|
| Entry price | $18/mo (Starter yearly) | Limited free plan, paid from ~$24/mo | Free, from $16/mo yearly |
| Main focus | Corporate training, e-learning | Marketing, social, creative video | Text-based video and audio editing |
| Avatar realism | High, consistent | High, more expressive for social | No avatars: edits real footage |
| Voice cloning | Yes, cross-lingual | Yes | Own synthetic voice (Overdub) |
| Enterprise integrations | SCORM, LMS, SSO on Enterprise | More limited | Not its focus |
The comparison is really about intent. Synthesia is built for L&D departments, HeyGen for marketers, Descript for people editing real recordings rather than generating fake ones.
Verdict
If you produce training or internal video at any volume, Synthesia pays for itself quickly, and the ability to revise by editing text is the reason.
If you want video for social media or advertising, HeyGen is the more natural fit. And if you already film real people and just want faster editing, Descript is a different and probably better answer.
Start on the free plan. Ten watermarked minutes will tell you whether an avatar is acceptable to your audience, which is the only question that really matters here.
