About Synthesia

What the product does and where it fits

Synthesia replaces much of a conventional presenter-video workflow with a browser editor. Start with an idea or existing material, let its AI Video Assistant draft scenes and narration, select an avatar and voice, then edit the result using layouts, media, captions, branding, and generated B-roll. The result is a complete business video rather than a single text-to-video clip.

The platform is especially strong when a team must update or localize the same information repeatedly. A script can be revised without arranging another shoot, and one-click translation extends a project across more than 160 languages. Interactive buttons and branching are available on higher plans, while quizzes, SCORM export, SSO, advanced team controls, and the full avatar library are concentrated in Enterprise.

Synthesia now includes broader generative tools, including image and video models inside its AI Playground, but its product design still prioritizes structured, on-brand communication. Teams seeking open-ended cinematic experimentation across many independent image, video, and audio workflows may prefer a broader multi-model studio.

Verdict

Is Synthesia worth it?

Synthesia is one of the strongest AI video generators for repeatable business communication. Its free plan is generous enough to test the core workflow, and Starter works for light individual use. Creator or Enterprise makes the most sense when personal avatars, interactive delivery, localization, collaboration, governance, and LMS integration save enough production time to justify the higher price.

FAQ

Synthesia frequently asked questions

Short answers to the questions buyers commonly ask before choosing a creative software platform.

What is the Synthesia AI video generator?

Synthesia is a browser-based AI video platform for business. It turns prompts, scripts, links, documents, PDFs, and presentations into editable videos with AI avatars, voiceovers, captions, generated visuals, translation, collaboration, interactivity, and analytics.

Is Synthesia free to use?

Yes. Synthesia's Basic plan includes 1,200 credits per month, usable for up to 10 minutes of video, 9 stock avatars, AI voices in 160+ languages, and core creation tools. Free videos retain Synthesia branding and do not include every paid export, avatar, brand, or collaboration feature.

How much does Synthesia cost?

As checked on August 25, 2026, Basic is free, Starter is $29 per month, Creator is $89 per month, and Enterprise uses custom pricing. Included credits, video minutes, avatars, seats, downloads, interactivity, and enterprise controls differ by plan.

How do you create a video with Synthesia AI?

Start with a prompt, script, URL, PDF, document, or presentation. Choose an avatar and voice, edit the generated scenes and branding, add captions or visuals, then generate the video. Paid plans add downloads, personal avatars, interactive elements, API access, and broader team workflows.

Can Synthesia translate AI videos?

Yes. Synthesia supports voice and video creation across more than 160 languages and accents. Translation, dubbing, captions, and lip-sync help teams localize one approved video without filming every language version separately, although plan limits vary.

What is Synthesia best used for?

Synthesia is best suited to presenter-led training, onboarding, compliance, sales enablement, product explainers, internal communications, and localized business videos. It is less specialized for unrestricted cinematic experimentation or hands-on professional timeline editing.

What are the main disadvantages of Synthesia?

The strongest interactive, LMS, governance, avatar, and collaboration capabilities sit on higher plans. Avatar delivery can still require quality checks, longer projects take time to generate, and presenter-style output may not suit campaigns that need natural human performance or highly cinematic visual control.

How is Synthesia different from HighReach?

Synthesia is optimized for structured business videos built around AI presenters, translation, interactivity, analytics, and LMS delivery. HighReach is a broader multi-model creative suite for generating and transforming image, video, audio, avatar, and campaign assets with more freedom to choose the production model and workflow.
