Synthesia.

Synthesia is an AI video platform for businesses that turns a written script into a studio-quality video presented by an AI avatar, with voiceovers in more than 140 languages. It is built for training, onboarding, compliance and internal communications teams who need a steady supply of video but have no camera crew, studio or editing suite. According to Synthesia, you can start free with no credit card required, paid plans start at $18 per month billed yearly, and the platform is already trusted by 90% of the Fortune 100.

What is Synthesia?

Synthesia replaces the traditional video shoot with a text box. You type or paste a script, choose an AI avatar to present it, pick a voice and language, and Synthesia renders a finished presenter-led video. The company says more than 2,000,000 users work on the platform, and its homepage case studies centre on employee training, compliance training, technical training and sales enablement — the kinds of video that change often and are painful to reshoot.

Because the “presenter” is software, everything about a Synthesia video stays editable. Change a policy number, rename a product, or translate the whole piece, and you regenerate rather than re-film. Synthesia sums up the pitch as saving up to 90% of the time and cost of video production compared with traditional shoots.

Pros

• No cameras, actors or editing skills needed to ship professional video
• One script becomes videos in 140+ languages with consistent terminology
• Edits propagate automatically to links, embeds and SCORM packages
• Serious compliance posture — SOC 2, GDPR, ISO 42001 and SAML/SSO
• Free to start, with analytics included to prove training impact

Cons

• The presenter-led format suits training and explainers, not cinematic brand ads
• An AI presenter can still feel synthetic for sensitive customer-facing messages
• Regular production means budgeting for a paid plan after the free start
• Output quality still depends on writing a clear script in the first place

Who should use Synthesia?

Synthesia fits learning and development teams, HR departments producing onboarding at scale, compliance teams whose material changes with every regulation, and global companies that must localise the same message into many languages. Internal communications and sales enablement teams are also natural users.

Synthesia FAQs

Is Synthesia free to use?

Synthesia offers a free way to start: the Basic plan costs $0, needs no credit card, and includes 500 credits a month — about ten minutes of watermarked video. Paid plans start at $18 a month billed yearly for Starter, which suits teams publishing training or marketing videos regularly.

How many languages does Synthesia support?

Synthesia creates voiceovers in more than 140 languages, and its automatic translation keeps names, terms and pronunciation consistent with glossary controls. That means one Synthesia script can become localised videos for every market you serve, without booking separate voice actors or studios for each language.

Can Synthesia turn a PowerPoint into a video?

Yes. Synthesia’s AI Assistant turns documents, PowerPoint files and even pasted links into polished, on-brand videos in minutes. You can then adjust the avatar, voice and language before publishing the Synthesia video as a link, an embed or a SCORM package for your learning platform.

Is Synthesia good for employee training?

Synthesia is built with training in mind: it is trusted by 90% of the Fortune 100 according to Synthesia, publishes directly to SCORM for learning management systems, and built-in analytics show views and completion. When a policy changes, you edit the Synthesia script instead of reshooting.

Final Verdict

Synthesia has become the default name in AI avatar video for a reason: it turns the slowest, most expensive kind of business content — presenter-led training — into something a small team can produce, translate and update from a browser. The free start makes it easy to judge the avatar quality against your own standards. If your organisation makes training or explainer videos more than occasionally, Synthesia deserves a serious trial.
