Claude for Word: What the Add-in Does, and When You Need an Export Instead

What is Claude for Word?

Claude for Word is an add-in made by Anthropic that brings Claude into Microsoft Word. Instead of switching between claude.ai and your document, you ask Claude questions and request edits in a panel inside Word, and it works directly on the document you have open. It's aimed at people who draft, review and negotiate documents — contracts, memos, reports — and it's available on Claude's Pro, Max, Team and Enterprise plans.

Searches for "Claude to Word" usually mean one of two things: Claude working inside Word (this add-in), or a claude.ai conversation turned into a .docx file (an export). The comparison further down helps you pick.

What the Claude for Word add-in can do

Based on Claude's official documentation for Claude for Word, the add-in can:

• Answer questions about your document with clickable citations that jump to the section it's referring to.
• Edit selected text while keeping the surrounding styles, numbering and formatting.
• Work in tracked changes, so every edit lands as a revision you can accept or reject in Word's review pane.
• Work through comment threads, editing the text each comment is anchored to and replying with what it changed.
• Summarize a counterparty's redlines and flag the changes worth pushing back on.
• Fill templates with drafted content that inherits your document's heading and paragraph styles.
• Find every provision on a theme using meaning rather than exact keywords.

Requirements

Anthropic's companion add-in for spreadsheets is covered in Claude to Excel.

How to add Claude to Microsoft Word

For yourself:

1. Open the Claude for Microsoft 365 listing on Microsoft AppSource.
2. Select Get it now to install it.
3. Open Word, activate the add-in, and sign in with your Claude account.

You can also start from inside Word: click Add-ins on the Home tab and search for "Claude".

The search results mix Claude's listings with unrelated third-party AI add-ins, so check the publisher before you click Add. The listing Claude's documentation points to is Claude for Microsoft 365.

For a whole organization, an admin can deploy the add-in from the Microsoft 365 Admin Center (Settings → Integrated apps → Add-ins, with Office Store access allowed for users), assigning it to everyone or to specific users and groups. Once deployed, people activate it from Home → Add-ins on Windows or Tools → Add-ins on Mac and sign in. Claude's documentation also covers deployment with a custom manifest when the Office Store is turned off.

Claude for Word vs exporting a Claude chat to Word

The quickest way to choose is by where your content lives right now.

Choose the add-in when the work belongs in an existing Word document and you want Claude to edit it in place. Choose an export when the valuable part is already in a claude.ai conversation — an explanation, a plan, a table, a derivation — and you want it in Word to keep, edit or hand over.

How to get a claude.ai conversation into Word

If what you need is the conversation itself:

1. Install the extension in a Chromium browser on your computer.
2. Open the chat on claude.ai.
3. Click Word at the top right for the whole chat, or at the bottom of one response for just that answer.

The .docx keeps headings, lists, code blocks and real Word tables, and writes math as editable Word equations — details in exporting a Claude chat to Word. Copying by hand works for short answers; the two parts that usually break have their own guides: pasting tables into Word and getting equations into Word.

What about asking Claude to create a Word file?

There's a third option people mix up with the other two: asking Claude on claude.ai to generate a brand-new .docx. With file creation turned on, Claude writes the document from your prompt and you download it from the chat. That's useful for drafting a new letter or template, but it isn't an export — Claude rewrites the content rather than copying your conversation. See can Claude create a PDF or Word file for how that works and when to use it.
