# CLI Overview

> hiair-cli: the companion app that fills applications in your own Chrome

`hiair-cli` is a small companion app you install on your own computer. It doesn't replace your Hiair account — it's how applications actually get filled and submitted.

When you queue an application on [hiair.ai](https://hiair.ai) or in Copilot, the job goes to your paired computer. `hiair-cli` opens a disposable Chrome window there, fills the form, and writes the result back to your [application tracker](/features/application-tracker). Nothing runs in a cloud browser — it's your Chrome, your session, your IP.

<Note>
  You need the CLI paired to a computer before any application can be filled. See [Install & pair](/cli/install) to get started.
</Note>

## What you need

* **Python 3.11 or newer**
* **Google Chrome** installed
* **A paired device** — one computer running the CLI, connected to your Hiair account

## The two ways to run it

<Tabs>
  <Tab title="Login worker — hands-off">
    Install it once with `hiair service install` and it starts automatically whenever you log in. Queue jobs from the website or Copilot and they get filled in the background — no terminal needed.
  </Tab>

  <Tab title="Foreground — hiair apply">
    Run `hiair apply` in a terminal to watch a batch process in real time. Useful for a one-off run, or when you want to see exactly what's happening. Ctrl-C stops any in-flight applications.
  </Tab>
</Tabs>

Both do the same job — the login worker is macOS-only, so `hiair apply` is how you run applies on other platforms.
