Our hands-on review of Synthesia
A typical Synthesia workflow begins with a script, prompt, document, or URL.
The AI Video Assistant can analyze the source material and create a structured multi-scene video draft. You can then select an avatar, customize the script, choose layouts, add branding, and incorporate AI-generated B-roll.
For companies, this workflow removes many of the traditional production steps:
Source material → Script → AI Avatar → Voice → Visuals → Branding → Translation → Export
The platform is particularly practical for content that needs to be updated frequently. If a product feature, company policy, or training procedure changes, the video can be edited and regenerated rather than requiring a new filming session.
Personal avatars are also available on paid plans. Synthesia requires the person represented by a personal avatar to provide explicit consent, and the platform supports avatar creation from recorded video or, on supported plans, a photo combined with live consent footage.
How Synthesia actually works
Start with a prompt, script, document, URL, or presentation. Let Synthesia create an initial video structure. Choose an AI avatar and voice. Edit the script and scene layouts. Add images, screen recordings, animations, or AI-generated B-roll. Apply your brand colors, fonts, logos, and visual assets. Generate the video. Translate or dub it into additional languages if required. Review and collaborate with your team. Export, share, embed, or publish the finished video.
Synthesia can generate videos from text and other source material, while its AI Playground adds generated visual assets and B-roll to the workflow.
Pricing: is it worth the money?
Synthesia currently offers Basic, Starter, Creator, and Enterprise plans.
Basic
$0/month
The free Basic plan includes 1,200 credits per month and can be used for up to 10 minutes of video or other supported AI usage. It is primarily intended for exploring Synthesia and testing its avatars and voices.
Starter
$29/month when billed monthly, with lower effective pricing when billed annually.
Starter includes 1,200 monthly credits, AI Video Assistant, AI dubbing, video downloads, removal of the Synthesia logo, 125+ Synthesia avatars, and personal/on-brand avatar capabilities.
Creator
$89/month when billed monthly, with lower effective pricing on annual billing.
Creator increases the available credits and adds features such as personal avatars, branded video pages, API access, multiple avatars per scene, interactive videos, and additional collaboration capacity.
Enterprise
Custom pricing
Enterprise is designed for larger organizations and includes features such as unlimited video minutes, expanded avatar access, shared workspaces, Brand Kits, SSO, organizational controls, and higher-scale API capabilities.
Synthesia's current credit system uses 2 credits per second of generated video. A one-minute video therefore consumes 120 credits. Credits also apply to other AI features such as dubbing and generated visual assets, and unused credits do not roll over into the next billing period.

Our verdict
Synthesia is built primarily for professional business communication at scale. Its combination of AI presenters, multilingual voiceovers, automated video creation, branding, translation, collaboration, and enterprise controls makes it particularly useful for organizations producing recurring training, sales, marketing, and internal communication videos.
Its main distinction is that the platform treats AI video as a communication workflow rather than simply a cinematic generation tool.

Who should NOT use this tool

It may also be excessive for users who only need simple talking-head videos occasionally and already have access to a camera, presenter, or conventional editing workflow.
