# Chat and modes

> How the WPOS chat works: modes, auto plan, voice, attachments, context, conversations, and tasks.

The chat is the heart of the [Command Center](/operate/command-center). You ask in
plain language, the agent acts on the site, and the preview updates. A few controls
shape how it works.

## Modes

The mode sets how the agent approaches a request. You can change it per chat, and
set a default in [Settings](/operate/settings).

    The default. A good balance of speed and depth for everyday changes.

    More thorough reasoning for harder or higher-stakes work.

## Controls

* **Auto plan.** When enabled in [Settings](/operate/settings), the agent shows a
  plan before executing complex tasks, so you can review the steps before it
  touches the site.
* **Voice input.** Dictate your request instead of typing.
* **Attach.** Add a file to your message, or click an element in the preview to
  attach it (the [click-then-ask](/operate/command-center) loop).
* **Context window.** Each conversation has a context budget. You can clear context
  or compact a long conversation from [Settings](/operate/settings) when it gets
  heavy.

## Conversations and tasks

* **Conversations.** Your chat history is kept, so you can reopen earlier threads
  and pick up where you left off.
* **Tasks.** Longer pieces of work show up in the Tasks panel with their status, so
  you can track what the agent is doing without watching the chat the whole time.

<Tip>
  Start in Balanced for routine edits and switch to Expert when a task is tricky or
  important. Turn on Auto plan when you want to see the agent's intended steps
  before anything changes.
