# Partner Integrations

> Official Cartesia integrations on third-party platforms

These guides describe how to integrate Cartesia's models into other products and developer frameworks. Details live in partner documentation and repositories.

## Prerequisites

You’ll need these for most integrations. Individual pages also list extra requirements, such as partner accounts and SDK installs.

* **[Cartesia API key](https://play.cartesia.ai/keys)** — create and manage keys in the Playground.
* **A voice** — pick one in the Playground or API; see [Choosing a voice](/build-with-cartesia/capability-guides/choosing-a-voice).
