You sit down to build an intro deck for your app, and thirty minutes later you are still staring at a blank first slide. As an indie developer, I have come to feel this is the most wasteful kind of time. The content is already in my head — only the order and the framing are missing, and that alone stops me from moving. What Claude in PowerPoint changed for me was exactly this friction of the very first slide.
What Claude in PowerPoint Does
Claude in PowerPoint is an add-in that brings Claude directly into Microsoft PowerPoint. It can suggest slide structure, generate body text, draft speaker notes, and rephrase existing slides — all without leaving PowerPoint.
The key is to treat it not as a tool that produces a finished deck in one shot, but as a partner that prepares a fast first draft. When a starting point appears in thirty seconds, you get to spend your own time reordering and polishing the words instead.
Installation and Setup
You install it from the Microsoft 365 add-in store.
- Open PowerPoint and go to "Insert" > "Get Add-ins"
- Search for "Claude for PowerPoint" and install it
- Sign in with your Anthropic account
A "Claude" tab then appears in the ribbon. If sign-in stalls, check that you are already logged into Anthropic in your browser — that usually clears it quickly.
Drafting a Whole Deck at Once (Generate Deck)
The feature that helps most is "Generate Deck," which produces a full set of slides from a topic.
- Select "Generate Deck" from the Claude tab
- Enter the topic, target audience, and slide count
- Claude shows a structure outline — fix the order and headings, then click "Generate"
The important habit here is not to hit Generate immediately. Reviewing the outline first — "is this the right flow?" — sharply reduces how often you have to regenerate the body text. Titles, body copy, bullets, and speaker notes all get filled in at once, so the time you spend building a foundation is simply saved.
Rephrasing Existing Slides (Improve Slide)
To tidy up a slide you already have, select it and use "Improve Slide":
- Condense text: Trim overstuffed paragraphs down to the key points
- Visual suggestions: Flag places that could become a table, chart, or diagram
- Tone adjustment: Shift between boardroom and internal-share styles to fit the audience
The one I lean on is "condense text." Left to myself, I write too explanatorily and cram too many characters onto a single slide. Asking Claude to cut it down to read-aloud bullets makes the slide far easier to take in.
Building Prompts That Actually Work
The quality of the result is mostly decided by how specific your instruction is.
❌ "Make a presentation about sales"
✅ "Create a 10-slide executive report on Q4 2025 sales performance.
Include year-over-year growth, regional breakdown, and outlook
for next quarter."
The good example hands over three things: the audience (the executive meeting), the elements to include (growth, breakdown, outlook), and the length (10 slides). Decide those three up front and the structure comes back with far less variance.
Asking for speaker notes separately also pays off. After the body is settled, "add a supporting note to each slide, written to be spoken aloud in about a minute" gives you a presenting script at the same time. Slides stay sparse and readable; the explanation moves into the notes.
Drawing the Line: Handmade Work, AI for the Materials
Alongside app development I also keep up an art practice, and I have decided not to use AI for the creative work itself. For the materials that explain that work, though, I rely on AI fully — exhibition notices, app intro decks, activity reports. The work of conveying, not creating.
That line fits a tool like Claude in PowerPoint remarkably well. I think about the substance; AI shapes it into something that reaches people. As a division of labor that protects time for the creative work, this is where I have settled. If presentation prep has been eating into your real work, I suspect this split will help.
How to Think About Copilot
PowerPoint also offers Microsoft Copilot. The two overlap a lot, so the realistic approach is to choose by what you value.
| Feature | Claude in PowerPoint | Copilot for PowerPoint |
|---|---|---|
| Auto-generate slides | Yes | Yes |
| Following long instructions | Reflects fine-grained conditions well | Standard |
| Natural Japanese | Near-native | Supported |
| Custom instructions | Flexible | More template-based |
If you want to hand over detailed conditions at once and nail the structure, Claude fits; if you want something continuous with the rest of Microsoft 365, Copilot fits.
Where People Get Tripped Up
The first stumble is usually the order in which you apply a brand template. Apply the template after generating, and text can overflow its frames and break the layout. If you use a company or personal template, apply it first and then run Generate — you will do far less visual cleanup.
The second is that generated bullets, left as-is, are too dense. AI tries not to drop any element, so receive the output expecting to cut down to three or four points per slide, and your audience will thank you.
Start Here
On your next deck, before you start writing the clean version, run Generate Deck just to get a structure outline. Fix the order, fill in the body, then add speaker notes last. Working in that order, the blank-first-slide stall simply disappears. Thanks for reading.
