Deck Design for Non-Designers

On this page

This article is for Nick, Emma, and Carlos. For anyone who's ever thought "I'm not a designer" and assumed that means their deck won't look good. For anyone who's spent a Sunday evening fighting with PowerPoint, or felt embarrassed sharing a deck next to a competitor's slick presentation.

Here's the truth: you don't need design skills. You need clear words. The AI handles the design — the spacing, the colours, the typography, the layout, the animations. Your job is to tell it what matters. And you already know what matters better than any designer, because it's your business.

The AI Is the Designer. You're the Director.

Think of it like hiring a talented designer and briefing them. You wouldn't tell a designer which font to use or how many pixels of padding to add. You'd say: "I want this to feel professional" or "the revenue number should be the biggest thing on the slide" or "can you add something that makes viewers spend more time on the team page?"

That's exactly how Dev Decks works. You direct. The AI designs.

And here's the reassuring part: even with no direction at all — just "build me a sales deck" — the AI produces something that looks genuinely professional. You're not starting from zero. You're starting from good, and you can make it exceptional whenever you want.

Five Rules Anyone Can Follow

Rule 1: One Idea Per Slide

The single most impactful thing you can do. If a slide tries to say two things, it says neither clearly. One number, one comparison, one testimonial, one CTA — per slide.

Not sure if you've got too much? Ask yourself: "If someone glances at this slide for 3 seconds, will they get the point?" If the answer is no, there's too much on it.

"This slide is trying to do too much. Split it into two slides — the metrics on one, the testimonial on the other."

"One idea per slide. This one has pricing AND a feature comparison AND a CTA. Make each its own slide."

Rule 2: Say What You Want to See

You don't need design vocabulary. Describe what you'd sketch on a whiteboard.

Instead of: "I need better visual hierarchy with appropriate typographic scale."

Say: "Make the revenue number the biggest thing on the slide. Everything else should be smaller."

Instead of: "I need a more sophisticated colour palette with strategic accent usage."

Say: "Use our brand colours more. The green should only be on the most important things."

Instead of: "Can you implement a more dynamic layout with asymmetric proportions?"

Say: "Put the big number on the left and the small details on the right."

The AI understands plain English better than design jargon. Say what you see in your head, and it builds it.

Rule 3: Include Your Actual Numbers

Don't say "add a traction slide." Say "add a traction slide — we have 1,200 customers, £240k MRR, and 34% monthly growth."

Real numbers give the AI real material to work with. It can size things proportionally, create meaningful comparisons, and build counters that climb to your actual figures.

"Traction slide: 1,200 customers, £240k MRR, 34% month-over-month growth, NPS of 72. Make the MRR the hero number."

The AI can't invent your numbers. But once you give them, it can make them look incredible.

Rule 4: Reference What You Like

The easiest shortcut: point to something that works and say "like that."

"Make the team slide look like the one on our competitor's website — circular photos, clean grid."

"I liked how slide 3 turned out. Can you apply the same style to slide 7?"

"Make this feel like an Apple keynote — clean, centred, lots of white space."

"The pricing section from the sales deck I saw last week had a good layout — three columns with the middle one highlighted. Do that."

You don't need to describe the design from scratch. Referencing something you've seen — another slide in your deck, a competitor's site, a famous brand — gives the AI a target.

Rule 5: Iterate, Don't Perfect

Your first message doesn't need to be perfect. Say something simple, see what the AI builds, then refine.

Round 1: "Add a team slide with our 4 founders." Round 2: "Put them in a grid with circular photos." Round 3: "Add a hover effect that reveals their background."

Three simple messages. A slide that would take hours in PowerPoint. Each round is a low-pressure conversation, not a high-stakes design decision.

"This is close but the headline should be bigger."

"Love the layout — just make it feel more premium. Darker background."

"Nearly perfect — add some entrance animation so the cards appear one by one."

What Non-Designers Worry About (and Why They Shouldn't)

"I'll make something ugly"

You won't. The AI handles visual design — colours, spacing, typography, proportions. Even your simplest request produces a professionally designed slide. The floor is already high.

"I don't know the right words"

There are no right words. "Make it bigger" works. "This feels cluttered" works. "I want the viewer to notice the revenue number first" works. If the AI misunderstands, you just clarify. It's a conversation, not an exam.

"What if I'm too specific and mess it up?"

You can't mess it up. Every change is reversible. If you ask for something and don't like the result, say "undo that" or "go back to what it looked like before." There's no risk in trying.

"Design tools are too complicated for me"

Dev Decks isn't a design tool. There are no layers, no drag-and-drop, no colour pickers, no alignment guides. You type what you want in plain English. If you can send a text message, you can build a deck.

"My competitor has a professionally designed deck"

So do you now. The AI designs slides at a professional level — animations, hover effects, data visualisation, brand consistency. Nick's competitor might have paid a designer £2,000. Nick's deck looks just as good and took 5 minutes.

Prompts for Non-Designers

Here are starter prompts that require zero design knowledge. Copy any of them:

For a first deck:

"Build a sales deck for my company. Use our website for branding. Keep it clean and professional."

For making a slide better:

"This slide is boring. Make it more interesting."

"The text is too small. Make everything bigger and simpler."

"I want this to feel more premium — whatever that means to you."

For adding features you didn't know existed:

"Can you make the numbers count up from zero?"

"Add something that happens when I hover over the team photos."

"Make the slides animate — each element should appear one at a time."

For fixing problems:

"There's too much on this slide. Simplify it."

"The most important part is the revenue number but it doesn't stand out."

"This doesn't feel like our brand. Make it match our website more."

Real Personas, Real Prompts

Nick (sales rep, low tech): "Build me a sales deck I can send to retail prospects. Use our website. Keep it simple — I don't have time to mess around with it."

Emma (nursery owner, below Nick-level): "I need a deck for our nursery open day. It should feel warm and safe — parents need to trust us with their children. Use photos from our website."

Carlos (personal trainer, phone-first): "Build a deck about my personal training services. I need one version for gyms and one for corporate clients. Make it look professional — not like a Canva template."

Priya (estate agent, low-medium tech): "Create a property listing deck for a 3-bed semi. It should look professional and include the key details: price, rooms, neighbourhood. Make it photo-heavy."

Each of these prompts is 1-2 sentences. None require design knowledge. All produce professional results.

The Permission Slip

Your deck will look professional. Not because you learned design, but because the AI designs every slide specifically for your content, your brand, and your audience. You don't need to earn the right to have a great-looking deck. You already have it.

The only thing standing between you and an exceptional deck is trying it. Paste your URL. Tell the AI what matters. See what happens. Refine from there.

You're not a non-designer using a design tool. You're a business person using a deck tool. And the deck tool handles the design.
