Synthesia is an AI video platform for creating presenter-led business content from a script. It is commonly used for training, onboarding, product explainers, and internal communication when repeated filming would be slow or expensive.
Core workflow
- Start from a blank project, template, document, or supported import workflow.
- Divide the script into short scenes with one idea per scene.
- Select an available stock, customizable, personal, or studio avatar appropriate to your plan.
- Choose a language and voice, then add text, media, screen recordings, and brand elements.
- Preview pronunciation, timing, transitions, captions, and on-screen claims before generation.
- Share by link or export in the formats available to your account.

Avatars and languages
Synthesia advertises a large library of AI avatars and support for more than 160 languages and voice options. Availability varies by plan and locale. Personal or custom avatar creation requires the subject’s participation and consent; it should not be treated as permission to generate any message indefinitely.
Translation and updates
A major advantage is the ability to revise a script or localize a training video without reshooting a presenter. Translation can accelerate rollout, but a fluent reviewer should still check terminology, tone, text expansion, captions, and voice pronunciation. For policy or safety material, have the responsible subject-matter owner approve the final version.
Team and brand features
Templates, shared assets, brand controls, comments, and workspace permissions can help teams standardize production. The useful governance layer is human: assign an owner, preserve the approved script, record the review date, and archive superseded exports.
Limitations
Avatar delivery can feel less expressive than a real instructor, especially for emotional or persuasive content. Complex names and acronyms need pronunciation testing. Rendering minutes, seats, avatar types, translations, downloads, and integrations differ by plan, so verify the live comparison before committing.
Consent and disclosure
Use only authorized voices, likenesses, scripts, and media. Do not fabricate endorsements or impersonate colleagues and public figures. Disclose synthetic presenters whenever viewers could reasonably believe the person recorded the exact message.
Verdict
Synthesia is well suited to structured business video that must be updated or translated repeatedly. It is less compelling when authentic emotion, spontaneous demonstrations, or documentary credibility are central.
