Synthesia

What Is Synthesia?

Synthesia is an AI video generation platform that turns written scripts, documents, or presentations into professional-looking videos featuring realistic AI avatars, without needing a camera, actors, studio, or video editing skills. Instead of filming a person, users type or paste a script, choose an AI presenter from a library of avatars, and Synthesia generates a finished talking-head video with natural lip-sync and voice. In short: Synthesia answers the question "how do I turn a script or a PowerPoint deck into a polished presenter-led video without hiring a videographer or being on camera myself?"

Synthesia is widely used for corporate and training content, where speed, consistency, and multilingual reach matter more than cinematic production value, and has become one of the best-known names in the AI avatar video category.

Core Features and Toolkit

At the center of Synthesia is its script-to-video engine: users can type a script directly, generate one from a prompt, or convert an existing PowerPoint deck, PDF, Word document, web link, or ready-made template into a video automatically. This makes it possible to turn existing training material, sales decks, or internal documentation into video content without starting from scratch.

Synthesia offers more than 1,000 AI voices across 160-plus languages and accents, and videos can switch languages scene by scene, with the AI avatar's lip movements automatically adjusting to match. A single video created in one language can be auto-translated and regenerated in 140-plus additional languages, with the avatar's mouth movements re-synced naturally to each new language track, which is a major advantage for global companies producing training or onboarding content for teams in multiple countries.

On the avatar side, Synthesia provides a large stock avatar library of realistic AI presenters that can be placed in different outfits, settings, and framing. Users can also create a Personal Avatar trained from a single photo and a short voice sample, producing an avatar that looks and sounds like a specific real person, useful for executives or trainers who want their own likeness to appear consistently across many videos without being personally re-filmed each time. Custom Studio avatars, built from professional footage, are also available for organizations that want an even higher-fidelity branded presenter.

Beyond basic script-to-video, Synthesia supports interactive video features, letting viewers make choices that change the video's path, which is useful for branching training scenarios and interactive onboarding. An API is available for teams that want to trigger video generation programmatically as part of a larger content or learning pipeline.

Who Uses Synthesia

Synthesia is used heavily by corporate learning and development teams to produce training and onboarding videos at scale, since scripts can be updated and regenerated quickly whenever a policy or process changes, without needing to reschedule a film shoot. Sales and marketing teams use it to create personalized outreach videos, product explainers, and localized marketing content across multiple languages from a single script. HR and internal communications teams use it for company announcements, culture videos, and employee onboarding. Educators and course creators use Synthesia to turn written course material into video lessons, and customer support and success teams use it to create how-to and product walkthrough videos without recurring filming costs.

Pricing and Plans

Synthesia offers a tiered pricing structure. A Free Basic plan gives new users a limited amount of video minutes per month to try the platform. The Starter plan is aimed at individuals and small teams, offering a set amount of video minutes per year and access to a large library of avatars. The Creator plan increases available minutes, avatar access, and unlocks features like API access and interactive video, aimed at teams producing content more regularly. An Enterprise plan, with custom pricing, offers substantially higher or unlimited video minutes, more Personal Avatars, and features suited to large organizations with strict security, compliance, or scale requirements. Starter and Creator plans include a limited number of Personal Avatars, while Enterprise plans typically allow more, and custom Studio avatars are available as an additional purchase.

Why Choose Synthesia

The main appeal of Synthesia is speed and repeatability: once a script is written, generating or regenerating a video takes minutes rather than the days or weeks required for a traditional video shoot, which matters enormously for organizations that need to keep training and onboarding content current. This also dramatically lowers the cost of producing video content compared to hiring presenters, camera crews, and editors for every update.

The second major appeal is multilingual reach. Because Synthesia can regenerate the same script into dozens of languages with automatically lip-synced avatars, global companies can localize training, marketing, or internal communications content without re-filming or hiring voice actors and dubbing studios for each market.
