Synthesia's ChatGPT plugin turns documents into videos

Synthesia now makes its business videos inside ChatGPT. The avatar-video maker launched a plug-in for the chatbot on Monday, November 2, 2026, in a blog post by product manager Dan Spooner. Synthesia says more than 50,000 businesses use its platform, according to Inc.

The plug-in turns material already in a conversation into a video. A user describes what they want, or shares a document, deck or spreadsheet, and ChatGPT asks a couple of questions about visual style and length before Synthesia builds the video in the chat. Synthesia says the videos use Syren, its fastest format, by default, and can combine motion graphics, avatars, voiceover, music and b-roll. Asking for a video "in Studio" produces one where an avatar reads a supplied script word for word, and that version opens in Synthesia's editor for scene-level changes.

Under the hood it is Synthesia MCP, a server the company built on the Model Context Protocol. The same server connects to Claude as a custom connector, but only ChatGPT gets a marketplace listing, where it installs as a plug-in. The company's pages do not agree on who can use it: the launch post says every Synthesia plan, the product-updates page says all paid plans, and the documentation says the MCP is open to everyone but still under development. The docs also note that a ChatGPT workspace admin controls whether the connector is available.

Synthesia says the plug-in works with other ChatGPT plug-ins, so a workflow can run once, on a schedule, or when something new lands in Slack or an inbox. Its own examples include turning every post in a product-releases channel into a 30-second launch video and checking BambooHR each weekday for new hires.

On cost, Synthesia's documentation says there is no extra charge during the public beta and that the plug-in draws on the same credits as the Synthesia editor. Creating a draft is free; generating the finished video uses the plan's video minutes, and Syren videos consume credits. Synthesia's plans run from $14 a month for Starter, billed yearly, to $59 a month for Pro, with Enterprise priced on request; the free Basic plan includes 500 credits a month.

Some work still happens outside the chat. Studio drafts cannot be edited from ChatGPT, so scene, narration and avatar changes go through the Synthesia editor. Syren videos are the opposite: they are edited by chatting and cannot be opened in the editor. Synthesia calls the MCP a public beta and says features and pricing may change.

To try it, open ChatGPT's plug-in marketplace, search for Synthesia, and connect; a free Synthesia account can be created during setup.
