Building a Prompt Library for Your Company

Save the prompts that work. A prompt library is your design system in words — layout, tone, interaction, data, and motion prompts that keep every deck on brand. Includes starter templates by persona.

You might think you need to describe the look and feel of every slide. You don't. The AI already has a design system — yours.

When Lurio extracts your brand from your website, it doesn't just grab your colours and logo. It reads your visual identity — your fonts, your colour palette, your brand's energy — and uses all of it to make design decisions on every slide. Your brand is the design library. Every slide the AI builds is already shaped by it.

What the AI Already Knows

When you create a deck, the AI starts with a rich understanding of your brand:

Your colours — not just where to put them, but how to use them. A bold red brand gets high-contrast, energetic slides. A muted blue brand gets measured, professional layouts. The AI adjusts spacing, contrast, and visual weight to match your palette's personality.

Your fonts — typography sets the tone before anyone reads a word. A clean sans-serif signals modern and approachable. A refined serif signals established and premium. The AI uses your fonts to reinforce the impression your brand already makes.

Your logo — placed consistently, sized appropriately, never competing with the content. The AI knows when to feature it prominently and when to keep it subtle.

Your industry and audience — the type of deck tells the AI who's watching. An investor pitch gets metric-forward, momentum-driven design. A client proposal gets structured, trustworthy layouts. A board update gets conservative, data-dense treatment.

All of this happens before you type a single word. Your slides already look like yours.

Consistency Comes From Brand, Not From Saved Prompts

In the early days of AI tools, people saved useful prompts in documents and spreadsheets — reusing them to get consistent results. That made sense when the AI had no memory and no context.

Lurio works differently. Your brand is persistent. It's applied to every slide in every deck you create. You don't need to remind the AI to "use our brand colours" or "keep it consistent with our style" — that's the default.

What creates consistency:

  • Good brand input — the more your extracted brand reflects your real identity, the better every slide looks
  • Steering that compounds — when you tell the AI "I love this energy," it applies that across subsequent slides
  • Audience context — telling the AI who's watching shapes every design choice

What doesn't create consistency:

  • Copy-pasting the same prompt into different decks
  • Describing your visual style from scratch every time
  • Keeping a list of "what worked before" to repeat manually

When Different Slides Should Feel Different

Not every slide in a deck should look identical. A great deck has visual rhythm — the opening has one energy, the evidence section has another, the close has a third.

The AI handles this naturally. It varies design intensity based on what's on each slide and where it sits in the story. But you can steer it:

"The opening slide should feel bold and confident. The data slides should feel structured and precise. The close should feel warm and personal."

"More energy on the traction slide — this is where we prove momentum."

"Calm this section down — three slides in a row with high intensity is exhausting."

You're steering the emotional arc, not specifying layouts. The AI translates your direction into design choices that fit your brand.

Building on What Works

The most powerful thing you can do is tell the AI what resonated. When a slide feels right, say so — and say why.

"This is exactly the energy I want. Apply it to the rest of the deck."

"The way you presented the metrics here — big number, small context — is perfect. Do the financial slides the same way."

"I love how clean this section feels. Don't add anything to it."

This is more effective than any saved prompt could be, because you're reacting to a real result — not guessing in advance what might work.

If You're Coming From Templates

If you've used PowerPoint or Google Slides, the instinct is to control everything — because templates gave you nothing. You chose the layout, you picked the colours, you positioned every element.

With Lurio, that instinct works against you. The more you prescribe, the less room the AI has to design. The slides that look most "professionally designed" are usually the ones where the user trusted the AI's first pass and steered with a few words rather than a detailed brief.

The shift: instead of "tell the AI what to build," try "react to what the AI built." You'll get better results in less time.
