Make presentations with Claude or ChatGPT

Claude and ChatGPT both have a PowerPoint add-in that builds and edits slides for you. Check every number before you present.

Picks: 4; ranked

Yes, you can do this inside PowerPoint with Claude or ChatGPT. Both publish an add-in that builds slides, rewrites them and edits the deck you have open. Claude's add-in needs a paid plan, while ChatGPT's also works on the Free plan. One thing to know first: both can change your whole deck, so work on a copy.

Good for

Consultants and analysts building decks from a company template
Managers turning notes into slides
Students who need a first draft of a talk
Claude Code users who generate .pptx files from scripts

The short answer

Our advice: pick Claude's add-in if you have a paid Claude plan and a company template. Pick ChatGPT's if you are on a free plan. On Free Claude, ask for a .pptx file in claude.ai instead.

Our pick: Claude

Our advice: Claude for template-heavy work on a paid plan, ChatGPT for a free start. Vendor limits are in the sections below.

Best for

Claude add-in for decks that must follow a company template
ChatGPT add-in if you want to start on a free plan
Claude in claude.ai for a one-off .pptx file on any plan

Skip it if

You will send the deck without checking numbers and charts
Your file comes from a source you do not trust
You use PowerPoint on iPad or Android

Build a deck in PowerPoint with Claude or ChatGPT

1
Install the add-in and open your template
Install the add-in from the Microsoft Marketplace, then open PowerPoint on the web, Windows or Mac. For Claude, go to Home > Add-ins on Windows or Tools > Add-ins on Mac and sign in with your Claude account. Open your company template first so the assistant can read its layouts.
2
Give it your material and ask for an outline first
Our advice: ask for the outline before the slides. Fixing the story is cheaper than fixing 10 finished slides.
Prompt
```
Here are my notes. Propose a 10-slide outline for a 15-minute talk to a finance team. One message per slide title. Do not add any figure that is not in my notes.
```
3
Build the slides in your layouts
Select the slide you want it to follow, then ask. Claude's docs say it reuses your slide master, fonts and colors.
Prompt
```
Build slides 1 to 5 from the outline using the layouts in this deck. Keep each slide to one message and put detail in the speaker notes.
```
4
Add charts and fix one slide at a time
Claude's docs say it makes native PowerPoint charts. ChatGPT's listing says native chart editing may not be supported yet, so check the chart is editable.
Prompt
```
Turn the table on slide 4 into a bar chart and add a one-line takeaway as the title.
```
5
No add-in? Ask for a .pptx file
In claude.ai, turn on file creation under Settings > Capabilities and ask for a .pptx file. This works on every Claude plan. In Claude Code, Anthropic's pptx skill creates and edits .pptx files.
Prompt
```
Create a 6-slide PowerPoint file (.pptx) on this topic, with a title slide, 4 content slides and a summary.
```
Uses pptx
6
Check numbers, sources and notes
Anthropic advises human review before you send client decks, and OpenAI's listing warns the add-in may change or delete content if a request is unclear. For more ways to build decks, see the presentation skills.
Tip: Our advice: save a copy before big edits and read every figure against your source.

Questions

Can Claude make a PowerPoint?

Yes. Claude has a PowerPoint add-in for paid plans, and claude.ai can create a .pptx file on any plan once file creation is on in Settings > Capabilities. The Claude to PowerPoint guide has the setup steps.

Can ChatGPT make PowerPoint presentations?

Yes. OpenAI publishes ChatGPT for PowerPoint, a sidebar add-in in Microsoft PowerPoint that can create and edit decks. It is available on Free, Go, Plus, Pro, Business, Enterprise, Edu and K-12, with limited usage on Free and Go (as of November 2026).

What is the best AI for PowerPoint presentations?

Claude and ChatGPT both build slides inside PowerPoint. Claude's docs describe template matching and native charts, but need a paid plan. OpenAI says ChatGPT's advanced chart, shape and formatting edits may be limited, but it runs on Free with limited usage. Our advice: pick Claude for template-heavy decks and ChatGPT to try it without paying.

Is the Claude PowerPoint add-in free?

Anthropic lists it for Claude Pro, Max, Team and Enterprise plans. On Free you can still ask Claude in claude.ai to create a .pptx file.

Does the Claude add-in work on Mac, iPad or the web?

It works in PowerPoint on the web, on Windows (Microsoft 365, build 16.0.13127.20296 or later) and on Mac 16.46 or later. Anthropic lists PowerPoint on iPad, on Android and the 2016 and 2019 perpetual versions as unsupported.

Can Gemini make presentations?

Yes, in Google Slides, not PowerPoint. Google says Gemini can create a fully editable multi-slide deck from one prompt, on plans such as Google AI Pro and Ultra and several Workspace tiers.

Does Microsoft Copilot work in PowerPoint?

Yes. Microsoft's Copilot is built into PowerPoint with Microsoft 365 Copilot, or with Microsoft 365 Personal, Family, Premium or Pro. Our advice: pick it if your company does not allow third-party add-ins.

Can Claude use my company template?

Yes. Anthropic's docs say the add-in reads the slide master, layouts, fonts and color scheme of the open deck and uses them for new slides.

Is it safe to put a confidential deck into an AI add-in?

Deck content is sent to the vendor when you ask it to work. Anthropic does not recommend its add-in for highly sensitive or regulated data without controls, so check your company policy first.
