Synthesia turns a script, a slide deck, or a PDF into a finished video with an AI presenter reading it aloud, in any of more than 160 languages, without booking a camera crew or a voice actor. For a company producing the same training video in five languages, that’s five fewer recording sessions, not five slightly different edits of one.

What Synthesia does
Synthesia describes itself as an AI video platform built for business use, citing adoption across the large majority of Fortune 100 companies as a marker of its enterprise focus. The core workflow turns a script, a PowerPoint deck, a PDF, or another document into a video presented by a customizable AI avatar, with adjustable outfits and settings. Built-in translation and dubbing extend that video into more than 160 languages without a separate voice recording per language. Synthesia also supports interactive video, quizzes and branching paths a viewer can respond to, plus analytics on how a video performs, and the company highlights compliance certifications including SOC 2 Type II, GDPR, ISO 42001, and ISO 27001 for enterprise security requirements.
What it saves you
Producing a corporate training or communications video the traditional way means booking a presenter or actor, a camera crew, and an edit pass, and if the same video needs to exist in five languages, that’s traditionally five separate recording sessions, or at minimum five dubbing sessions with separate voice actors, since a script can’t simply be filmed once and reused across languages. Synthesia’s script-to-video generation with built-in translation and dubbing removes the need for a new recording per language: one script becomes one avatar-led video, and the language versions come from the same underlying take rather than a new shoot. Updating content is the other recurring cost this addresses; a training video with outdated information normally means re-booking the same presenter and crew for a reshoot, while a script-based video can be updated by editing the text and regenerating, without scheduling anyone’s time.
How it simplifies your setup
A traditional corporate video pulls together a presenter, a filming crew, an editor, and, for multiple languages, separate translators and voice actors, coordinated across schedules that rarely line up easily. Synthesia collapses that into a script-in, video-out workflow: writing or pasting a script, or converting an existing slide deck or PDF, replaces the shoot entirely, and the translation and dubbing step happens inside the same platform rather than through a separate localization vendor. Interactive elements like quizzes and branching paths also remove the need for a separate e-learning tool layered on top of the video. For a communications or L&D team producing recurring training content across regions, that means one workflow and one platform instead of a chain of external vendors and a scheduling problem for each new video.
Who Synthesia is for
Synthesia is built for corporate communicators, HR and learning teams, and marketing departments at organizations that need recurring, multi-language video content without a production crew for each one; internal training and onboarding videos are a natural fit given the compliance certifications aimed at enterprise buyers. It’s a weaker choice for anyone making customer-facing brand video where an authentic human presenter matters to the audience, or for a creator who needs a genuinely unique visual style rather than an avatar-led format. Reviewers rate it well overall for the core avatar and translation workflow, while some note avatar realism and lip-sync still have limits worth checking against a specific use case before committing.

Common questions
Can Synthesia create a video from a slide deck instead of a script?
Yes, it can generate an avatar-led video from a script, a PowerPoint deck, or a PDF, converting existing written content into video rather than requiring a script written entirely from scratch or a separate filmed presentation put together with a camera crew and a full studio booking each and every time.
How many languages does Synthesia support?
It supports more than 160 languages with built-in translation and dubbing, so a single video can be localized into multiple markets without booking a brand new voice recording session or a separate translator and voice actor for every additional language version that eventually gets needed later on down the line.
Is Synthesia meant for internal training or customer-facing marketing?
It’s used for both, but its enterprise security certifications and avatar-led format are especially aimed at internal training, HR, and corporate communications use cases at larger organizations that need recurring, multi-language video content on an ongoing, repeatable basis every single quarter of the year without fail or any noticeable delay.
