How it works

Three paths to go from idea to finished presentation, all powered by the open PPF format.

1

Describe your presentation

Tell the AI agent your narrative, audience, and content. Pick a theme from pptx.gallery or define custom brand colors, fonts, and layouts.

2

Refine the PPF document

The multi-agent studio builds a PPF JSON document from your inputs. Edit slides, adjust charts, tweak copy — all in a live preview with version history.

3

Export to PPTX, PDF, or web

One click to generate a production .pptx file, PDF, web-viewable slides, or SVG/PNG exports. Download or share via link.

Full conversion pipeline

Every direction covered. Import existing decks, generate new ones, export anywhere.

PPF — the Presentation Format

PPF is an open-source JSON format for describing presentations. It separates content intent from rendering complexity, so AI agents can produce slide decks without wrestling with OOXML.

Bring your own JSON schema validators, extend with custom properties, or use the reference gallery at pptx.gallery for standard themes, layouts, color schemes, font pairings, and narrative templates.

Three ways to provide design choices

1. Reference pptx.gallery

Use named themes, color schemes, and font pairings from the curated gallery.

"colors": { "scheme": "ocean-depth" }
2. Custom JSON

Define every color, font, and layout inline with full schema validation.

"colors": { "primary": "#1a1a2e", "accent": "#e94560" }
3. AI-generated from inputs

Describe what you want in plain language. Our AI agents construct the PPF JSON from your intent.

Built for AI agents

A REST API that any agent framework can call. Send a PPF document, get a .pptx file back.
