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.

Once you've built a few decks, you'll notice something: certain prompts consistently produce the look and feel you want. Your favourite layout. Your preferred animation style. The tone that nails your brand. The data treatment that makes your metrics shine.

Instead of rediscovering these every time, save them. A prompt library is your company's design system — in words. It ensures every deck your team builds looks and feels like it came from the same brand, without anyone needing design skills.

What Is a Prompt Library?

A prompt library is simply a collection of prompts that work well for your company. You save the ones that produce results you love, organised by category, so anyone on your team can reuse them.

Think of it as a recipe book. You don't reinvent the recipe every time you cook — you use the one that works and adjust as needed.

The Categories

Layout Prompts

These define how your slides are structured. Save the layouts that feel most "you."

Examples to save:

"Our standard metrics slide: one hero number large and centred, three supporting metrics in smaller cards below. Brand accent on the hero number."

"Our two-column layout: key insight on the left (large, bold), supporting visual on the right. 60/40 split — text side gets more space."

"Our team layout: 2x2 grid with circular photos, name and role visible, hover reveals bio. Stagger entrance left to right."

"Our closing CTA: one bold headline, one button centred below it, dark background, generous white space. Nothing else."

Tone Prompts

These capture your brand's personality. Save the descriptions that consistently produce your look.

Examples to save:

"Our brand feel: confident but not aggressive. Professional without being corporate. Clean lines, generous spacing, brand colours used sparingly for emphasis."

"Our investor deck tone: data-forward and precise. Lead with metrics, minimal decoration. Conservative enough for institutional VCs but not boring."

"Our sales deck tone: warm and trustworthy. Not pushy. The prospect should feel like they're talking to a capable partner."

"Our board deck tone: structured, conservative, no flash. Data speaks for itself. Every slide scannable in 10 seconds."

Interaction Prompts

These define the interactive elements that make your decks distinctive. Save the ones that get positive reactions from your audience.

Examples to save:

"Always add hover reveals on team cards — photo and name visible, bio appears on hover."

"Pricing tiers should lift on hover with a subtle shadow. The recommended tier has a 'Most Popular' badge."

"Feature grids should use hover to reveal descriptions — keep the surface clean with just icons and titles."

"Comparison tables should highlight the row on hover — our column stays prominent, the comparison becomes focused."

Data Prompts

These define how your numbers are presented. Consistency in data treatment is one of the strongest brand signals.

Examples to save:

"Revenue always shows as an animated counter. Growth rate gets a comparison badge ('+X% YoY'). Customer count includes a trend arrow."

"Our dashboard layout: 4 metric cards in a row, each with the number large, a trend arrow, and a tiny sparkline. Counters climb in sequence, left to right."

"Traction slides use the hero-plus-supporting pattern: one massive metric centred, three smaller metrics in cards below."

"Progress indicators use filled horizontal bars with percentage labels. Green for on track, amber for at risk."

Motion Prompts

These define the animation style your brand uses. Save the movement patterns that feel right.

Examples to save:

"Default entrance: everything fades up from below. Subtle, not dramatic. 0.3 second duration."

"Important slides: content appears in sequence — headline first, then supporting elements one by one with a short stagger."

"Closing slide choreography: headline does a word-by-word reveal. Pause. Button grows from centre. This is our signature moment."

"Data slides: counters climb first, then badges and labels fade in. The numbers always have their moment before context arrives."

Building Your Library in Practice

Step 1: Build a Few Decks

Don't try to create a library from scratch. Build 3-4 decks first. Notice which results you love.

Step 2: Save What Works

When a slide turns out great, save the prompt that produced it. Write it down somewhere your team can find it — a shared document, a Notion page, a Slack channel.

Step 3: Categorise

Group your saved prompts by category: layout, tone, interaction, data, motion. You'll start seeing patterns — your brand has a natural style that emerges from the prompts that work.

Step 4: Standardise

Pick the best version of each prompt. If you have three layout prompts that all work, choose the one that's most consistently good. That becomes your standard.

Step 5: Share

Share the library with your team. When anyone builds a new deck, they start with the library prompts and adjust for their specific audience.

Starter Library Templates

For a Startup (Ahmed)

LAYOUT: Hero metric centred, supporting stats below in cards. 
TONE: Confident, data-forward, modern. Not corporate.
INTERACTION: Counters on all metrics. Hover on team cards.
DATA: Revenue as hero counter. Growth rate with comparison badge.
MOTION: Fade up entrance. Stagger on multi-element slides.
CLOSING: Bold single-line CTA. Button grows from centre.

For a Sales Team (Nick)

LAYOUT: Split screen for problem/solution. Grid for features.
TONE: Professional, trustworthy, not pushy. Clear and direct.
INTERACTION: Hover on pricing tiers. Hover on case study cards.
DATA: Before/after metrics. ROI anchored pricing.
MOTION: Subtle entrances. No dramatic choreography.
CLOSING: Two CTAs — 'Book a demo' and 'Start free trial.'

For an Agency (Sarah)

LAYOUT: Portfolio cards in a grid. Team as lead + supporting.
TONE: Polished, agency-quality. Match client's industry feel.
INTERACTION: Hover on portfolio cards reveals project details.
DATA: Case study metrics in comparison format (before → after).
MOTION: Staggered card entrances. Timeline draws itself.
CLOSING: Clear next step with timeline — 'Kickoff in 2 weeks.'

For Board Reporting (Lisa)

LAYOUT: Dashboard grids. Structured tables with colour coding.
TONE: Conservative, precise, authoritative. No startup energy.
INTERACTION: Minimal — static dashboards. Counters on key metrics only.
DATA: Metrics vs targets with traffic light indicators. Trend sparklines.
MOTION: Subtle fade-in only. No stagger, no choreography.
CLOSING: Decisions needed as numbered list. Clear, actionable.

Using the Library With Editions

Your prompt library becomes even more powerful with Audience Editions. The core library stays the same — but you add edition-specific adjustments:

Base library prompt: "Our standard metrics dashboard with 4 counter cards."

VC edition adjustment: "Lead with MRR as the hero. Add '+340% YoY' badge."

Angel edition adjustment: "Lead with the vision metric. Frame growth as 'early momentum.'"

Board edition adjustment: "Show all metrics vs targets with traffic light indicators."

Same layout, same data treatment, same brand feel — adjusted per audience.

When to Update the Library

Add a prompt when you discover something that consistently works well. If three decks in a row use the same data treatment and clients love it, that's a library-worthy prompt.

Update a prompt when you find a better version of something that's already in the library. "Counters climbing in sequence" might become "counters climbing in sequence with a sparkline underneath" after you discover that addition.

Remove a prompt when it no longer reflects your brand. As your company evolves, your visual style evolves too. The prompt library should be a living document.
