Claude for PowerPoint

Full review

Claude for PowerPoint is Anthropic’s add-in for Microsoft PowerPoint. It sits in a sidebar next to your deck and works on the presentation at the code level, reading slide structure, layout, and how the content fits together.

Code-level interaction

Claude for PowerPoint reads your deck structurally: slide order, content hierarchy, the slide master with its layouts, fonts and colours. That lets you:

• Create complete presentations from outlines or briefs
• Add slides in your company’s or a client’s template, using its layouts instead of inventing new ones
• Change one slide without touching the rest
• Turn bullet points into diagrams, process flows or native PowerPoint charts you can still edit
• Restructure slide order and the storyline
• Add speaker notes and talking points

Anthropic’s advice is to apply your template before you ask for content, so Claude has the right layouts to work with.

Practical workflow

The best workflow is conversational: describe the presentation you need, look at what Claude builds, and iterate. “Make the executive summary more concise.” “Add a competitive comparison slide after the market overview.” “Restructure the conclusion around the three key takeaways.” You steer; it does the moving of boxes and text.

What changed since I first reviewed it

The add-in is now generally available on every paid plan, Pro included, in PowerPoint on Windows, on the Mac and on the web. Three changes matter more than the rest:

One conversation across Office. If you also have the add-ins open in Excel, Word or Outlook, Anthropic says Claude can read from one app and write in another: pull the numbers from an Excel model into a slide, update a chart after you change the figures in Excel, or turn an open Word document into slides. It only works with files that are open, and it can’t open or switch files on its own. On Pro and Max this is on by default (the setting is called “Let Claude work across files”); on Team and Enterprise plans, an admin has to allow it.

Skills and connectors. The skills you’ve enabled in your Claude account work here too, either automatically or when you type / in the sidebar. A skill that knows your slide template or your house style travels into PowerPoint with you. Connectors bring in outside context from the sidebar.

Standing instructions. In the add-in’s settings you can write rules that apply to every conversation, such as “always use one-line bullets” or which accent colour to use for highlights. They apply in PowerPoint only.

What it knows about the rest of your work

What I’d find most useful is to start a deck in PowerPoint and have Claude bring in the knowledge and instructions from my other projects. Today that works partly. According to Anthropic’s documentation, two things come along from your Claude account: skills and connectors. Your projects in the Claude app, Claude’s memory, your chats and Cowork’s instructions aren’t mentioned, so I’d assume they stay behind. Chat history in the add-in is stored in your browser on that computer and doesn’t sync.

So the way to bring your other work into a deck is to put the instructions in a skill and the knowledge somewhere a connector can reach.

Where it fits next to Cowork and Claude Code

The Pitch, the 17-slide deck on this site, wasn’t made with the add-in. Claude Code wrote code that produces the PowerPoint file. For a new deck from scratch, I’d probably start like that, in Cowork or Claude Code. To keep working on a deck, or to edit one I already have, I’d open it in PowerPoint and use Claude there, in my own template. Anthropic’s own Cowork course suggests the same split: Cowork builds the first draft, and you refine it with Claude in PowerPoint.

Before you use it at work

At work, it’s an add-in like any other: your company decides whether you get it. IT can deploy it through the Microsoft 365 admin center, and companies that run Claude through Amazon Bedrock, Google Cloud Vertex AI or Microsoft Foundry can use it without individual Claude accounts, but then without the cross-app feature, and possibly without skills and connectors. The add-in doesn’t inherit custom data retention settings your organization has set, and its activity doesn’t appear in Enterprise audit logs. Anthropic also warns that outside files, such as downloaded templates or a vendor’s deck, can contain hidden instructions that try to steer Claude. Use it on files you trust.

The token cost reality

As with Claude for Excel, token consumption is the thing to watch. A deck with many slides eats tokens quickly, and the add-in draws on the same usage limits as the rest of your Claude account. On a Pro subscription ($20/month) you can hit limits during a long session. Max subscribers ($100-200/month) get more headroom. If you build decks all day, factor that into which plan you pick.

Who should use Claude for PowerPoint

Professionals who create presentations regularly — consultants, managers, sales teams, and anyone who spends time building decks. The ability to describe what you want and have Claude build or refine it saves significant time compared to manual slide editing. If you mostly build new decks from scratch, I’d probably start in Cowork or Claude Code instead; the add-in is for working on the decks you have.
