# ZeroTwo desktop app

## Your command center for complex work

Run projects in parallel, work with files, use your computer, and keep long-running work moving from one desktop workspace.

### Why use the desktop app

* **Keep every chat in view:** Move between projects and long-running work without losing context.
* **Create and inspect real outputs:** Open documents, spreadsheets, images, and other files in the same workspace.
* **Work across your tools:** Use the browser, desktop apps, and plugins, or schedule a task inside a chat.

## Get started with the desktop app

Install ZeroTwo, sign in, choose where to work, and send your first message.

1. **Install the ZeroTwo desktop app.** [Download ZeroTwo](https://zerotwo.ai/download/) for Windows or macOS.
2. **Open ZeroTwo and sign in.** Open the app, then sign in with your ZeroTwo account.
3. **Choose where to work.** Start a chat, create a project, or open a folder. ZeroTwo can use the files and context in the location you choose. [Learn about chats and projects](/projects).
4. **Send your first message.** Use the mode switcher to select **Chat**, **Cowork**, or **ZeroCode**. Describe the result you want and add any files or context ZeroTwo needs. [Learn how to use ZeroTwo](/use-zerotwo).
