The AI Assistant panel () lets you chat with an AI that has full access to your document. You can ask it to write, rewrite, extend, or restructure content — and it can also modify abbreviations, citations, variables, and styles.

Sending messages

Type your message in the input field and press Enter to send (use Shift + Enter for a new line). The assistant analyzes your document and responds with text, proposed changes, or both. Each chat conversation is stored in the chat history. You can start a new chat with the button or browse previous conversations via the button.

​
File attachments

Click the button to attach a file to your message. The assistant can read and analyze the file content as part of the conversation.

​
Knowledge base

Click the Knowledge button to enable the knowledge base for your message. When active, the assistant uses your uploaded reference documents and URLs as additional context.
The Knowledge toggle is only available when you have uploaded at least one resource in the Knowledge Base panel. If no resources are uploaded, the button is disabled.

​
Editor selection

You can select text in the editor and send it as context to the assistant:
  1. Select text in the editor — an overlay button appears above the selection.
  2. Click Add to Chat — the sidebar switches to the Assistant panel and the selection is attached to your next message.

Proposed changes

When the assistant modifies your document, it shows a change preview below its response. The preview summarizes what was changed — sections added, updated, or deleted, as well as changes to variables, abbreviations, citations, or style defaults.

​
What the assistant can do

The assistant is not limited to editing text content. It can modify multiple areas of your document:
AreaExamples

VariablesAdd, update, or remove document variables
AbbreviationsAdd or modify abbreviation definitions
CitationsAdd or update bibliography entries
StylesAdjust fonts, colors, spacing, captions, and other style defaults

​
Billing

Each message to the assistant consumes tokens from your plan. The token cost depends on the length of your document, the attached context (selection, knowledge base, files), and the complexity of the response.
For details on token pricing and plan limits, see Pricing.
