Build Better Slide Decks With AI (Works With Any Tool)

Grab the files or notes you want to turn into a deck. This could be a CSV export from Shopify or Google Analytics, a Zoom meeting transcript, a scope of work, or a messy notes document.

Your starting point does not need to look presentation-ready. This workflow is most useful when the source material is raw, messy, or too unstructured to drop directly into slides.

Start a new chat in Claude, attach your documents, and use this prompt:

I need you to turn these documents into a slide deck outline. Before you start, ask me five multiple-choice questions about the purpose, audience, tone, and structure so you get it right.

Claude may respond with a question like: “Who is the primary audience for this deck? A) Your direct team (internal update) B) Executive leadership (high-level summary) C) A client or external stakeholder D) Investors or board members”

Answering these questions helps Claude tailor the deck before it generates anything. A deck for your internal team should look different from a deck for a client, and Claude needs that context to avoid producing something generic.

Pro tip: You can add your own questions to the prompt. If brand tone matters, ask Claude to include a question about visual style. If there is a specific section you always need, like “next steps” or “budget impact,” tell it to ask about that too.

Answer Claude’s questions and let it generate the outline in markdown. Each top-level heading becomes a slide title, and bullet points become the content on each slide.

Claude should pull specific numbers, quotes, and details from your raw content, then organize them around the audience and goal you selected.

Example output: # Q2 Planning Summary Slide 1: Q1 Results at a Glance - Revenue: $1.24M (31% above plan) - Top performer: All-Star drop sold out in 8 hours - Repeat purchase rate hit 28% Slide 2: What Worked - Scarcity + event timing + strong creative = formula - Email open rate on ASW drop: 47% - Bundle pricing increased AOV by 22% Slide 3: Q2 Priorities ...

Read through the outline before moving to Gamma. If a slide feels off or you want to add something, ask Claude to revise the markdown first.

Add a slide about [your topic] after slide 3.

Make slide 5 more visual with a before/after comparison.

Iterate in Claude rather than in Gamma. It is much faster to edit markdown than to rearrange designed slides.

Pro tip: If you want Claude to match a format you have used before, paste in a previous deck outline and say, “Follow this same structure but with the new data.”

Go to gamma.app and click Create New. Select Generate from notes or outline, then paste in your outline from Claude.

Click Continue and review the preview of your deck.

On the preview page, select the Preserve and Concise options for the best slide deck result. Then click Generate, and Gamma will create a full deck for you.

From there, edit any slide with AI, tweak the design, and export the finished deck as a PowerPoint or PDF when you are ready to share.

At this point, you are editing a finished deck rather than building one from scratch. Claude handled the structure, narrative, and data; Gamma handled the design. Your job is final polish.

Pro tip: Gamma lets you present directly from the browser, so you do not need to export to PowerPoint unless your audience specifically needs a .pptx file.
