Agent Mode in PowerPoint

Turn PowerPoint Copilot into your personal slide builder.

Hey friends 👋

Welcome to another Signal Pro workflow issue.

Last month, McKinsey dropped their 74-page State of Organisations 2026 report.

I gave it to Microsoft 365 Copilot, told the PowerPoint Agent to build me an executive briefing, and received a polished slide deck in ~4 minutes. It was on-brand and ready to present.

Agent Mode in PowerPoint quietly started rolling out in February. It works on the web, Windows, and Mac. If you've been waiting for Copilot to click, this is the feature that makes it happen.

Today I’ll walk you through:

1. What Agent Mode in PowerPoint actually is and how it differs from regular Copilot

2. Building an executive deck from a 74-page PDF using nothing but conversation

3. The brand template technique that makes every slide Copilot generates match your company’s look on the first pass

Let’s get into it.

What is Agent Mode in PowerPoint?

Same concept as Agent Mode in Excel. It’s a setting inside Copilot in PowerPoint that switches the AI from answering questions about your slides into an autonomous agent that builds and edits your presentation directly.

A quick naming note: you might see this called “Edit with Copilot” in your interface. Microsoft recently renamed it from Agent Mode as it moved to general availability. It’s the same feature but under a new label. I’ll use both terms interchangeably in this issue, but when I say “activate Agent Mode,” look for “Edit with Copilot” in the Tools menu (above).

Regular Copilot in PowerPoint suggests content. Agent Mode creates slides, restructures sections, rewrites text, generates images, adds speaker notes, and translates entire presentations, all through conversation while you watch. It also conveniently maintains context across multiple prompts, just like you’re having a conversation with your favourite chatbot.

A few things to know before you start:

• Who has access: Anyone with a Microsoft 365 subscription can use basic Agent Mode features. If you have a Microsoft 365 Copilot license (the paid add-on), you also get access to your files, meetings, and emails. If you're on a business plan and can't see it, your IT admin may need to enable it.

• What it can do: Create new slides, edit existing content, restructure presentations, generate and replace images, rewrite text for clarity or tone, add speaker notes, translate slides or entire decks, and iterate on any of the above through follow-up prompts. You can also attach files directly in the chat.

• What it can’t do (yet): Full OneDrive/SharePoint file referencing inside Agent Mode is rolling out between now and June 2026. For now, save your source files to OneDrive and use "Add work content" in the chat pane to reference them.

Setting up Agent Mode

There are actually two entry points, and understanding the difference matters a lot.

1. PowerPoint Agent in Copilot Chat (for creating from scratch): Open the Microsoft 365 Copilot app, find the PowerPoint Agent, describe what you need, and it builds a complete presentation that saves directly to your OneDrive. You then open the file and refine.

2. Edit with Copilot inside PowerPoint (for editing and refining): Open an existing presentation, go to the Copilot panel, select "Edit with Copilot" from the Tools menu, and iterate on your deck through conversation. This is where you'll spend most of your time.

The first is for going from zero to a working draft. The second is for taking that draft and making it good. I use both in the workflow I'll show you.

Building an executive deck from a 74-page report

Here’s where things get practical. I’m going to take McKinsey’s State of Organizations 2026 report and turn it into an executive briefing deck. No manual slide creation or copy-pasting stats. Just through conversation.

The report is dense, data-rich, and exactly the kind of source material that consultants, strategists, and managers need to distil into something presentable.

Step 1: Start with the PowerPoint Agent in Copilot Chat

I haven’t read this report. I’ve skimmed the title page, and I know it’s about organisational transformation. That’s it. The whole point is that I shouldn’t need to read 74 pages before I can present the key findings.

First, make sure your source document is saved to OneDrive. Then open the Microsoft 365 Copilot app, select the PowerPoint Agent, and click the plus icon to add your source material. You’ll see three options: “Add work content,” “Upload images and files,” and “Attach cloud files.”

Use “Add work content.” This is important. When I manually uploaded the PDF using the upload option, the agent pulled information from the web instead of the attached document. When I used “Add work content” and selected the same PDF from my OneDrive, it focused exclusively on the report. The difference in output quality was significant.

I selected the McKinsey report from my drive and typed one line:

Create an executive briefing from the McKinsey State of 
Organizations 2026 report for senior leadership at a 
professional services firm.

That’s it. No bullet-pointed requirements or slide-by-slide instructions. Here’s why.

The PowerPoint Agent doesn't just take your prompt and run with it. It reads the document, then presents you with a Presentation Options panel. This panel typically includes two tailored questions based on what the agent found in your source material, followed by standard selectors for length, style, and theme.

The tailored questions change every time. In my case, it asked which strategic priorities my firm wants to address (I picked "AI transformation and automation") and what the primary objective of the briefing should be (I chose "Drive immediate decision-making on key initiatives").

When I ran the same prompt again earlier, it asked completely different questions, such as which themes to prioritise and how the briefing should conclude. The agent reads the document fresh each time and generates questions it thinks are most relevant.

The standard options stay consistent:

• Length: Auto, Concise (5-7 slides), Detailed (8-10), or In-depth (10+). I went with In-depth.

• Style: More visuals, balanced, or more text. I picked “More text” for a data-heavy briefing.

• Theme: A selection of visual themes. You have to pick one, so I went with Ember. Don’t overthink this if you’re planning to apply your own brand template later.

I enjoyed the level of hand-holding this approach provided. I didn't need to tell the agent what to focus on. It read 74 pages, identified the relevant themes, and asked me what mattered most. I just picked from a menu.

Every slide references the source document. At the bottom of each data slide, there's a citation linking back to the McKinsey report.

Step 2: Open in PowerPoint and switch to Agent Mode for refinement

The initial draft was solid but needed some work. The content was accurate (it pulled real statistics from the report), but the layouts were generic, and some slides tried to cover too much ground.

Here's the nice part: you don't need to leave the Copilot interface to start fixing that. Once the deck is generated, you'll see an "Open in PowerPoint" button in the top right. One click and you're inside the actual presentation with Agent Mode ready to go. No downloading or hunting through OneDrive folders. Creation and refinement are one continuous workflow.

With the deck now open in PowerPoint, I activated Agent Mode in the Copilot panel and started refining.

Prompt:

Add a third key number to the top of slide 3 alongside the 
1:5 ratio and 86% figures.

Agent Mode came back with a clarifying question: what should the third number be, and what’s the one-line caption?

This is the conversational part that separates Agent Mode from regular Copilot. It checks before it acts, rather than blindly executing actions.

Agent Mode inside PowerPoint doesn’t automatically have access to the source document you used to create the deck in Copilot Chat. It’s working with the slides, not the PDF. So when I wanted it to pull a specific stat from the McKinsey report, I had to point it back to the source:

mckinsey-state-of-organizations-report-2026.pdf reference the 
mckinsey presentation

Once it had that context, it added the 88% figure (organisations deploying AI in some form) with a matching caption and citation.

The brand template technique

This is the part that turns a decent AI-generated deck into something that looks like your organisation made it.
