# The editor

> A collaborative document editor with real page layout, headers and footers, tracked changes, version history, and Word and PDF export.

The Casa Conect **editor** is where you and the agent write together. It has true page layout, so documents look the way they will print. It is collaborative, so colleagues can type at the same time. It also speaks Word's language, tracked changes included.

## What opens in the editor

| Source                                | Opens as                                                                                                                          |
| :------------------------------------ | :-------------------------------------------------------------------------------------------------------------------------------- |
| **New document** in a vault           | A blank editor document                                                                                                           |
| A **Word** file (`.docx`)             | Imported, with its formatting, page setup, headers, footers and tracked changes. See [Word documents](/documents/word-documents). |
| **Markdown** and **plain text** files | Editable directly                                                                                                                 |
| A **matter's description**            | The same editor, inside the matter                                                                                                |
| A **skill**                           | The same editor, saved back as the skill's file                                                                                   |

Everything else, such as PDFs, images and spreadsheets, opens in the read-only [viewer](/documents/vault#the-viewer).

## Writing

Type `/` on an empty line for the block menu: **Heading 1–3**, **Bulleted list**, **Numbered list**, **Checklist**, **Table**, **Blockquote**, **Code block**, **Divider** and **Page break**. The toolbar covers character formatting, alignment, links and images.

Each document shows which vault it belongs to: **Project vault**, **Organization vault**, **Private vault** or **Shared Space**. Up to 12 documents can be open as tabs.

## Page layout

Open **Page setup** to control how the document is laid out.

| Setting                 | Options                                                                                                               |
| :---------------------- | :-------------------------------------------------------------------------------------------------------------------- |
| **Paper size**          | A4, A3, A5, Letter, Legal, Tabloid, or the custom size of an imported Word file                                       |
| **Orientation**         | Portrait or Landscape                                                                                                 |
| **Margins**             | Normal · Narrow (1.27 cm) · Wide (5.08 cm) · Custom                                                                   |
| **Headers and footers** | Separate content for the first page and for odd and even pages, with **Insert page number** and **Insert page count** |

Page breaks appear where they fall, so you can see as you write that a signature block has been pushed onto a page by itself.

## Working together

Several people can edit the same document at once. You see colleagues' cursors and their changes as they type. The connection indicator shows **Connected**, **Connecting** or **Connection interrupted**. If your connection drops, keep working. Your changes are sent when it returns.

The agent is a collaborator too. When it edits a document you have open, you watch the suggestions appear.

## The agent's edits

When the agent changes a document that already existed, its changes arrive as **[tracked changes](/documents/tracked-changes)**. A review bar appears, reading *"N AI suggestions"*, with **Accept all** and **Reject all**, and each suggestion can be resolved individually. Accepting or rejecting is an ordinary edit. Everyone viewing the document sees the result immediately.

## Versions

The editor saves continuously. There is no save button to forget. To mark a moment you may want to return to, choose **Save version**. **Version history** lists saved versions along with versions created by uploads, Word saves and the agent, and **Restore** brings one back without losing the current content. See [Versions](/documents/vault#versions).

## Export

| Export                       | Result                                                                                                                                                                                                             |
| :--------------------------- | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Download as Word (.docx)** | A Word file with your formatting and page setup. Pending suggestions are written as **real Word tracked changes** with their authors' names, so a reviewer opening the file in Word sees the same redlines you do. |
| **Export PDF**               | A PDF that paginates exactly as the editor and viewer show it, with headers, footers and page numbers                                                                                                              |

Conversion happens entirely inside Casa Conect's infrastructure. Your document is not sent to a third-party converter.

After an export you may see a note such as *"Exported — 2 parts of the document changed"*. The editor tells you whenever something could not be carried across exactly. [Word documents](/documents/word-documents#what-changes-in-translation) explains what and why.

## Limits

| Limit                     | Value                                                                                  |
