Synthesia Review (2026) — AI Avatar Video, Tested
The go-to for talking-head videos at scale (training, explainers, localisation). Avatars are impressive but not indistinguishable; great for volume, less so for emotional storytelling.
The Good
- Script-to-video in minutes
- 140+ languages for localisation
- Consistent, reusable brand avatars
- No filming or editing needed
The Bad
- Avatars can feel slightly robotic
- Paid only, and not cheap
- Limited for narrative/emotional video
Overview
Synthesia creates videos from a written script using AI avatars ("presenters"), aimed at training, explainer and corporate content — no camera, studio or actor required.
What it's good at
Volume and localisation. You can produce a polished talking-head video in minutes, update it by editing text, and generate the same video in 140+ languages. For L&D and product teams, that removes the whole filming/editing pipeline.
Where it falls short
The avatars are good but not fully lifelike — fine for corporate explainers, weaker for emotional or narrative video. It's paid-only and pricing scales with minutes, so heavy use adds up.
Should you use it?
For training, explainers and multi-language corporate video at scale, it's excellent value in time saved. For brand storytelling that needs real human warmth, keep a real presenter.

FAQ
Are the avatars convincing?
For corporate/explainer content, yes. For emotive storytelling they still read a little synthetic.
Can it localise a video?
Yes — that’s a core strength; one script can be produced in many languages with matching avatars.
