Synthesia

Synthesia is an AI video platform designed primarily for businesses that want to create professional video content without cameras, studios, actors, or traditional video production teams. It combines AI avatars, synthetic voices, video templates, localization, editing, and collaboration tools in one workspace, making it particularly useful for corporate training, employee onboarding, sales enablement, internal communications, customer education, and learning and development. A user can start with a script, prompt, document, presentation, or even a PowerPoint file and turn that material into a narrated video with an AI presenter. It offers a large selection of ready-made avatars representing different appearances, professions, and presentation styles, while businesses can also create personal or custom avatars for a more consistent brand presence. Its newer avatar technology focuses on expressive delivery, allowing presenters to gesture and act rather than simply read lines with basic lip synchronization. Creators can also customize elements such as outfits, backgrounds, layouts, brand colors, and on-screen content to produce videos that fit an organization's existing visual identity. Language support is another major part of Synthesia's offering. The platform supports video creation in more than 160 languages and voices, allowing businesses to produce localized versions of training, marketing, or customer-facing content without organizing additional recording sessions. AI dubbing and translation can also be used to adapt existing videos for international audiences while maintaining synchronized speech and the presenter's voice characteristics.

It is built with larger teams in mind as well. Shared workspaces, real-time collaboration, brand kits, analytics, permissions, SSO, and enterprise administration tools make it possible for organizations to manage video production across multiple departments rather than treating every video as an individual creator project. The platform also includes interactive features such as quizzes, calls to action, branching experiences, and roleplay sessions, which can turn a standard presentation into a more engaging learning or practice experience. For companies that want to integrate AI video into their own products, it provides API access for capabilities such as video generation, personalized video, dubbing, and interactive avatars. Its pricing uses a credit-based system, with free and self-serve plans available alongside enterprise options with larger usage allowances and additional administrative features. For businesses considering a Synthesia alternative, the most important areas to compare are avatar realism, language coverage, video customization, translation and dubbing, collaboration features, interactive content, API capabilities, security, and pricing. Synthesia is best suited to organizations that see AI video as part of their broader communication and training workflow rather than simply as a tool for generating short creative clips.
