The companion to PPTX.dev
The reference catalog for presentation design choices.
Every layout, color scheme, font scheme, narrative, chart type, and image treatment an OPF document can reference — in one browsable catalog. Built for humans looking for inspiration and AI agents selecting design choices programmatically.
You came for the design. Leave with the deck.
pptx.gallery is the open reference catalog; PPTX.dev is the OPF engine; STORYD is the presentation workflow that turns this vocabulary into a finished, story-driven deck in your voice. Free to start, no card.

Presentations should have a shared design vocabulary
Every deck is a collection of named choices — layouts, color schemes, font schemes, narrative arcs, image treatments. But those names have never lived anywhere browsable. So humans guess, AI agents hallucinate, and everyone rebuilds the same design references from scratch.
"The design dictionary for presentations — human-readable, machine-queryable."
Built for two audiences
Every page serves humans looking for inspiration and AI agents selecting design choices programmatically — never one at the expense of the other.
For humans
Browse real presentation designs organized by dimension. Use the named choices as vocabulary when describing what you want to a colleague or an AI.
- Free, no accounts, no downloads
- Visual previews with usage guidance
- 74+ long-form how-to articles
For AI agents
Query the catalog during presentation generation. Every design choice has a stable OPF name that the entire ecosystem — PPTX.dev, DeckChat, STORYD — shares.
- Structured JSON per live dimension
llms.txtdiscovery index- JSON-LD structured data on every item
Gallery dimensions
Eleven dimensions live today, each sourced from the OPF schema on PPTX.dev.
Layouts
Slide layout templates — content zones, placeholders, spatial arrangement. The OPF-named structural patterns a deck is built from.
Color Schemes
Presentation color palettes — primary, secondary, accent, background. Stable OPF names that agents and humans share as a vocabulary.
Font Schemes
Heading and body font schemes for OPF decks. Each scheme is a named choice OPF documents can reference directly.
Backgrounds
Slide background styles — solid, gradient, pattern, image. Cross-linked with color schemes for consistent visual identity.
Narratives
Story structures and frameworks for sequencing slides. The narrative arcs that shape how a presentation unfolds over time.
Charts
Chart type definitions, data requirements, and OPF base-type coverage for presentation data stories.
Themes
Complete visual systems that compose color schemes, font schemes, backgrounds, and default layouts into one OPF theme.
Audiences
Audience profiles that guide OPF tone, chart density, narrative structure, color schemes, and layout defaults.
Headers & Footers
Repeatable slide metadata patterns for slide numbers, dates, logos, legal lines, and classification markers.
Content Blocks
Pre-composed slide sections — pitch intros, KPI dashboards, timelines, quote slides, and closing CTAs with copyable OPF.
Image Treatments
Image placement, crop, overlay, mask, caption, and filter patterns for OPF slides that use photography or screenshots.
Part of the PPTX ecosystem
PPTX.gallery is the reference layer. Other tools in the ecosystem generate and author presentations — and they all speak the same design vocabulary defined here.
PPTX.dev
The engine and OPF schema. Every gallery item references an OPF-named design choice defined on PPTX.dev.
DeckChat
Chat-driven presentation authoring. Uses gallery names as the shared vocabulary with users.
STORYD
AI-native presentation creation. Selects design choices from the same catalog that lives here.
Quick Design Principles
Keep these fundamentals in mind for every presentation you create.
Simplicity
One idea per slide. Remove everything that doesn't serve your message.
Hierarchy
Guide the eye with clear visual hierarchy. Make important elements stand out.
Consistency
Use the same fonts, colors, and styles throughout your entire deck.
Purpose
Every element should have a reason to exist. If it doesn't add value, remove it.
