Hello, this is Hamamoto from TIMEWELL.
"Creating presentation materials takes hours" — in 2026, ChatGPT offers a powerful solution to this common business challenge. Particularly notable is the newly introduced "Agent Mode," which enables ChatGPT to directly generate .pptx files.
This article covers four methods for creating slides with ChatGPT — including the latest features available as of January 2026 — from a practical perspective.
New in 2026: Direct Generation with Agent Mode
What Is Agent Mode?
"Agent Mode," introduced in 2026, significantly enhances ChatGPT's ability to execute tasks autonomously. Unlike the traditional conversational interface, it can handle everything in one flow — from drafting a structure to designing slides and generating the .pptx file.
Availability:
- ChatGPT Plus, Pro, or Team plans (paid plans only)
Key features:
- Automatically executes multiple steps: Advances through required tasks autonomously without the user needing to give instructions at every turn
- Proposes and refines structure: Suggests the overall slide structure and begins generation after approval
- Direct .pptx generation: Creates a PowerPoint file on the spot
How to Use Agent Mode
- Choose a plan: Subscribe to ChatGPT Plus or higher
- Enable Agent Mode: Select Agent Mode from settings
- Enter your prompt: "Please create a presentation introducing Japan"
- Review the structure: Review the AI's proposed structure and make changes as needed
- Generate and download: Download the .pptx file once generated
Pros:
- Low effort; easy to use even for beginners
- Produces an editable .pptx file
- Consistent quality from structure through generation
Cons:
- Paid plans only
- Design customization has its limits
Method 1: Generate .pptx with Advanced Data Analysis
A Standard Feature That's Been Around
Advanced Data Analysis (formerly Code Interpreter) is a standard feature available for ChatGPT Plus and higher. It runs Python code to perform data analysis and file generation.
Step-by-Step Process
- Enable Advanced Data Analysis: Confirm in settings
- Enter your prompt: "Please output a PPTX file. The content should be slides explaining Japan"
- Instruct code execution: "Please run this using Code Interpreter right here"
- Download the file: Download the generated file
Notes and Troubleshooting
If an error occurs:
- Add the instruction: "Check if it's in MNT/DATA"
- MNT/DATA is the temporary directory where generated files are stored
Examples of refinement instructions:
- "Please make the content richer"
- "I'd like to include some diagrams too"
Pros and Cons
Pros:
- Works entirely within ChatGPT's native features
- Produces an editable .pptx file
- Useful for text-based structure drafting
Cons:
- Design quality and visual expression are limited
- Struggles with diagrams and charts (may produce garbled output)
- Errors can occur
Best for:
- Early-stage "drafts" or "structure outlines"
- Simple, text-heavy slides

Method 2: High-Quality Slides with GPTs "Slide Maker"
What Are GPTs?
GPTs are customized versions of ChatGPT built for specific purposes. You can find and use a wide variety of GPTs in the GPT Store.
Features of "Slide Maker"
"Slide Maker" is a GPT specialized in creating presentation slides, with the following capabilities:
| Feature | Description |
|---|---|
| Structure proposal | Suggests the overall slide structure in advance |
| Automatic image insertion | Automatically selects and places relevant images |
| Rich text | Generates text at an explanatory writing level |
| Online editing | Can be edited directly in the browser |
Workflow
- Launch Slide Maker: Search for it in the GPT Store and select it
- Enter your theme: "Make slides introducing Japan"
- Review the structure: Review the proposed structure (e.g., 12 slides)
- Start generation: Reply "Please go ahead" to begin generation
- View on external site: Transition to a linked site where the slides are displayed
- Edit: Fine-tune with the "Edit" button
Output Quality
Demo results:
- Title: "The Diverse Appeal of Japan"
- Each page includes relevant images
- Rich text content covering culture, food, tourism, and more
- Visually polished design
Pros and Cons
Pros:
- Visually excellent slides with images
- Consistent content based on the proposed structure
- Editable online
- Good balance of quality and speed
Cons:
- Depends on an external service
- Terms of service and privacy policy require review
- Applying corporate templates may be difficult
Best for:
- When you want a certain level of quality with minimal effort
- When visual elements are needed in the slides
Method 3: HTML/React Slides with the Canvas Feature
What Is the Canvas Feature?
The Canvas feature opens a dedicated display area on the right side of ChatGPT to preview and run content written in HTML, CSS, and JavaScript in real time.
Enabling and Basic Usage
- Enable Canvas: Turn on "Canvas" in the settings menu
- Select a model: Choose a supported model (GPT-4o or higher)
- Enter your prompt: "Please create slide materials explaining Japan, about 5 slides"
- Specify the format: Explicitly state "Please make it in HTML, slides"
- Real-time preview: Displays in the Canvas area on the right
Interactive Slides with React
What is React? A JavaScript library well-suited for building interactive UIs.
Features of React slides:
- Page switching with a "Next" button
- Animation effects
- More advanced interactions
An Iterative Refinement Process
Examples of design improvements:
- "Add diagrams and icons to make it look better"
- "The image section is too tall vertically — please make it smaller"
- "Change the background color"
The AI interprets instructions, modifies the code, and you can confirm in the preview as you converge on the ideal design.
Pros and Cons
Pros:
- Very high design customization
- Iterative refinement process
- Interactive elements can be added
- Also a good way to learn web technology
Cons:
- Not a .pptx file — it's a web page (HTML) format
- Not suited for offline presentations
- Requires some trial and error
Best for:
- Unique, interactive presentations
- Users familiar with web technology
- Cases where creativity and freedom are valued
Other Approaches in 2026
Automation with VBA Macros
You can also have ChatGPT generate macro code using PowerPoint VBA (Visual Basic for Applications).
Pros: Can leverage all PowerPoint features Cons: Requires knowledge of macros
ChatGPT Add-ins
Some third-party add-ins allow you to call ChatGPT directly from within PowerPoint.
Note: Security and privacy must be verified
