Independent review. IonBin has no partnership with Synthesia and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.

Creates presenter-style videos with AI avatars and voices from a script. Its MCP server (public beta) and API let an AI assistant turn a script it wrote into a video draft.

Best for
  • Training, explainer and product videos without filming
Not for
  • Teams that can't use a beta integration (Synthesia's MCP is in public beta)

Top use cases

  • Turn a script or idea into a Synthesia video draft from Claude or ChatGPT source ↗
  • Create a video from a template through the API source ↗
  • Generate personalized videos in bulk from a spreadsheet source ↗

How to use it with AI

How Synthesia connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.

PlatformMCP / connectorAPI (agent-written code)BrowserUpload / export
Claude (incl. Claude Code) Confirmed Named in Synthesia's MCP docs Synthesia docs ↗Claude (incl. Claude Code) MCP docs ↗ Confirmed Claude (incl. Claude Code) can run code; Synthesia publishes an API.

OpenAI Codex Not documented Synthesia has an official MCP server and OpenAI Codex supports MCP, but Synthesia's docs don't name this pairing. Auth setup may differ.

Google Antigravity Not documented Synthesia has an official MCP server and Google Antigravity supports MCP, but Synthesia's docs don't name this pairing. Auth setup may differ. Synthesia MCP docs ↗Google Antigravity MCP docs ↗ Confirmed Google Antigravity can run code; Synthesia publishes an API. Synthesia API ↗Google Antigravity docs ↗ Confirmed Browser subagent via /browser, documented as an Antigravity App feature; the IDE has separate browser docs Google Antigravity browser docs ↗ Confirmed Export from Synthesia, then works on local projects and worktrees Google Antigravity docs ↗

Synthesia's docs also name: ChatGPT.

Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
