Switch on file creation in Claude
This setting lets Claude make real PowerPoint files you can download. It works on every plan, including Free.
- Open claude.ai and go to Settings, then Capabilities.
- Turn on code execution and file creation.
- On a Team or Enterprise plan, it lives in Organization settings, then Capabilities, and is usually on already.
Paste your deck prompt
Claude shows you the slide list first. Fixing a list takes seconds; fixing a built deck takes longer.
- Start a new chat in Claude and attach your logo and any notes.
- Copy your prompt below, paste it in and send it.
- Read the slide list. Ask for changes until the order feels right.
- Type "Build it".
Make the slides for my live talk as a PowerPoint (.pptx) file. THE TALK - Title: [TALK TITLE] - Length: 30 minutes - My sections, in order: [YOUR SECTIONS ONE PER LINE WITH THE MAIN POINTS UNDER EACH] 1. PLAN FIRST Show me a numbered slide list before you build anything: the slide title and the one point it makes, grouped under my sections. Tell me how many slides it comes to. Then wait for me to type "Build it". 2. THE DESIGN - 16:9, made to be read on a shared screen from across a room. - A title slide, then a divider slide at the start of each section. - One idea per slide. Big text, short lines, plenty of space. - The same layout, fonts and colours on every slide. - Put a simple icon, diagram or shape where it helps a point land. No stock-photo filler. 3. THE WORDS - Use only the points and wording I've given you. - Where a slide needs something I haven't given you, like an example, a number or a story, put a highlighted box that says "[ADD: ...]" and what goes there. Never make it up. - Leave the speaker notes empty. 4. WHEN IT'S BUILT Give me the .pptx file to download, then list every [ADD] box by slide number.
Fix it in the chat
Same chat, plain words. Claude rebuilds the file with each change.
Make slide 6 two slides. It has too much on it. Move the section 3 divider before slide 14. Use a darker background on every divider slide. Swap the icon on slide 9 for a simple three-step diagram. Make all body text at least 28pt.
For small word changes, it’s quicker to open the file in PowerPoint, Keynote or Google Slides and type them in yourself.
Or: try Gamma for a more designed look
Gamma builds decks with layouts, diagrams and images, and exports to PowerPoint.
- Sign in to Gamma and paste the prompt below into the prompt bar on your dashboard.
- Answer its questions about your audience and style, or tap "Decide for me".
- Check the plan it shows you, then let it build.
- To download, click Share or the three-dot menu, choose Export, then PowerPoint or PDF.
A presentation for my live talk, "[TALK TITLE]" (30 minutes). 16:9, made to be read on a shared screen. One idea per slide, big text, a divider slide for each section. Use only my wording below. Where a slide needs an example or number I haven't given, write "[ADD: ...]" instead of making one up. My sections, in order: [YOUR SECTIONS ONE PER LINE WITH THE MAIN POINTS UNDER EACH]
Run through it once on your real screen
Slides that look fine on your laptop can be hard to read when shared on a call.
- Fill every [ADD] box with your own example, number or story.
- Open the file in the app you’ll present from and click through every slide.
- Share your screen on a test call and check the smallest text is easy to read.

If something goes wrong.
Claude wrote out the answer instead of giving me a file
Check that code execution and file creation is on in Settings, then Capabilities. Then type: "Give me this as a .pptx file to download."
My fonts look different when I open the file
The font isn’t installed on that computer, so the app swaps in another one. Install the font, or type: "Use a font that comes with PowerPoint instead."
There’s too much text on the slides
Type: "Cut every slide to one point and no more than 12 words. Split anything longer into two slides."
Claude added an example I never gave it
Type: "Replace anything I didn’t give you with an [ADD] box. List them by slide."
I want it in Google Slides
Upload the .pptx file to Google Drive and open it with Google Slides.
