# Welcome to Cluster



Sign in once at [cluster.app](https://cluster.app) or in the iOS and Android
apps, and your conversations, files, and subscription stay in sync across every
device.

## What you can do [#what-you-can-do]

* **Search** — ask anything and get an answer built from the live web, with
  citations you can check.
* **Chat** — brainstorm, write, and work through problems with the model you
  choose.
* **For Work** — hand off a task. A bot opens the apps, does the work on its own
  computer, and reports back with every step visible.
* **Build** — describe an app and get a running one with a shareable link. Pick
  the session up in your terminal with [Cluster Build](/docs/build/overview).
* **Create** — generate images from a prompt and refine them in the same thread.
* **Upload files** — PDFs, images, spreadsheets, and code, for analysis and
  summarization.

## Plans and usage [#plans-and-usage]
