Most people spend 30 minutes on a single slide. They tweak fonts, rearrange boxes, rewrite the headline three times, and still aren’t sure if it actually communicates anything useful.
I’ve been using Claude AI to cut that process down to under 5 minutes, and the output looks closer to a McKinsey deck than anything I was producing on my own. Here’s exactly how I do it.
What Makes a McKinsey Slide Different
Before getting into the prompt, it helps to understand what separates a McKinsey-style slide from a normal one. It comes down to three things.
The title is the insight, not the topic. Instead of “Q3 Sales Performance,” it says “Q3 sales dropped 12% due to distributor delays in Southeast Asia.” One idea per slide, no cramming. If you have three points, you have three slides. And the visual supports the title; it doesn’t repeat it or contradict it.
That’s the standard. Simple in theory, hard to execute under time pressure. That’s where Claude comes in.
The 5-Minute Process
Step 1: Give Claude your raw thinking (1 minute)
Don’t try to write a clean prompt. Just dump what’s in your head:
“I need a slide about why our market share is dropping in Turkey. The main issue is that local brands are undercutting us on price and dentists are recommending cheaper options to price-sensitive patients. Our product is better but that’s not resonating in this segment.”
Then add this at the end:
“Turn this into a McKinsey-style slide. Give me: (1) an insight-driven title, (2) three supporting points max, (3) a recommendation for what to do next.”
Step 2: Review the output (2 minutes)
Claude will return something structured. The title will be sharper than what you wrote, and the three points will actually be distinct from each other rather than three ways of saying the same thing.
This is where you spend your two minutes: checking whether the logic holds. Does the title match the supporting points? Is the recommendation actionable or just vague? If something’s off, tell Claude specifically what to fix. Don’t start over.
Step 3: Build the slide (2 minutes)
Take Claude’s output directly into PowerPoint or Google Slides. If you’re using a clean template, the formatting takes under two minutes. The key is resisting the urge to add more. McKinsey slides work because of what they leave out.
A Real Example
I ran this recently with a competitive analysis I was putting together. My raw input was messy, three paragraphs of observations from a market visit. Claude returned:
- Title: Local competitors are winning on price, not quality, and the market doesn’t yet value the difference
- Point 1: Three domestic brands entered the mid-tier segment in the past 18 months, each priced 30-40% below international alternatives
- Point 2: Dentist referral patterns follow patient affordability, not clinical outcomes
- Point 3: Premium positioning is ineffective without a visible clinical proof point at the point of recommendation
- Recommendation: Shift short-term focus to clinical educator partnerships rather than price competition
That took 4 minutes total. The slide was cleaner than anything I had written across three pages of notes.
Why This Works
The reason most people’s slides are weak isn’t that they don’t know the content. It’s that they’re too close to it. They include everything because everything feels important when you’ve lived it for a week.
Claude forces structure by design. When you ask for three supporting points and a recommendation, you’re forcing yourself to prioritize. You just have help doing it.
The McKinsey framework isn’t magic. It’s a discipline of putting the conclusion first and making every element of the slide earn its place. Claude is good at applying that discipline to raw, unstructured thinking.
One Thing to Watch Out For
Claude will occasionally make the title too cautious. Something like “Market conditions present challenges in the mid-tier segment” instead of a real conclusion. If the title doesn’t tell you what to think or do, push back. Ask for a version that takes a clear position.
The best titles are ones where someone could read just the title and walk away with the key point, even without seeing the slide body.
Bottom Line
If you’re spending more than 10 minutes on a single slide, the problem usually isn’t the design. It’s that you haven’t decided what you’re trying to say yet. Claude helps you get there faster. The 5 minutes isn’t the point. Clarity is.
