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

The Rundown In this guide, you will learn to take raw, unstructured data and turn it into a presentation-ready slide deck. This works whether you're starting from a spreadsheet, a meeting transcript, a long document, or just bullet points. Who This Is Useful For A marketing manager who runs the same monthly performance report and spends two hours every month rebuilding the same deck with updated numbers An agency owner who needs to turn a 12-page scope of work into a 7-slide kickoff deck their client's team will actually read An ops lead who just sat through a 40-minute planning meeting and needs to send the executive team a clean summary of what was decided and what's next What You Will Build A complete, designed slide deck generated from raw content you already have. No starting from a blank slide. No dragging text boxes around. The finished product comes out of Gamma fully designed with your structure, data, and narrative already in place. What You Need to Get Started Claude (free or Pro) at  claude.ai Gamma account (free tier works) at gamma.app Any raw content: a CSV export, meeting notes, a document, a transcript, even a rough outline Step 1 Grab whatever files you want to start with. This could be a CSV export from Shopify or Google Analytics, a meeting transcript from Zoom, a scope of work, or even a messy notes doc. The messier the better. The whole point of this workflow is that your starting point doesn't need to look anything like a presentation. The messier and more "un-presentable" it is, the more time this saves you. Step 2 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 will come back with something 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" This is the step most people skip, and it's the reason most AI-generated decks feel generic. Instead of telling Claude exactly what to build, you let it figure out what you need first. A deck for your team looks nothing like a deck for a client, and Claude can only make that distinction if you tell it. 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's a specific section you always need (like "next steps" or "budget impact"), tell it to ask about that too. Step 3 Answer Claude's questions and let it generate the outline in markdown. Each top-level heading becomes a slide title. Bullet points become the content on each slide. It will pull specific numbers, quotes, and details from your raw content and organize them based on the audience and goal you chose. The output will look something like: `# 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. If a slide feels off or you want to add something, just tell Claude: "Add a slide about [your topic] after slide 3" or "Make slide 5 more visual with a before/after comparison." Iterate here, not in Gamma. It's much faster to edit markdown than to rearrange designed slides. Pro tip:  If you want Claude to match a format you've used before, paste in a previous deck outline and say "follow this same structure but with the new data." Step 4 Go to  gamma.app  and click  Create New . Select  Generate from notes or outline  and paste in your outline from Claude. Click  Continue , then review the preview of your deck. On the preview page, select the  Preserve  and  Concise  options to get the best slide deck. Then click  Generate  and Gamma will create a full deck for you. From here you can edit any slide with AI, tweak the design, and export as a PowerPoint or PDF when you're ready to share. The key thing is you're editing a finished deck, not building one. The structure, narrative, and data are already there because Claude did that work. Gamma handled the design. You're just doing final polish. Pro tip:  Gamma lets you present directly from the browser. No need to export to PowerPoint unless your audience specifically needs a .pptx file. Going Further Once you've done this workflow once, save your Claude-generated outline as a template. For recurring reports (weekly marketing updates, monthly board decks, client recaps), you can give Claude the outline and have it fill it in with new data and content. You can also chain this with other tools: use Zapier to auto-export your analytics data on a schedule, drop it into Claude via the API, and have a draft deck waiting for you every Monday morning.
