Prompt in, deck out

Describe the deck. Get one that looks designed.

superGamma plans an outline, fills every slide against a bento grid, and picks chart forms from the shape of your data. No template stamping, no empty tiles, no screenshot of a chart you can't edit.

01Under the deck

A design system, not a prompt wrapper

The model only ever fills shapes that were designed first. Everything below is enforced in code, so a bad generation is rejected rather than shipped.

One source of layout truth

The screen and the .pptx cannot drift apart

Tile placement is computed once, by one function. The React renderer turns it into CSS grid areas; the exporter turns the same tiles into inches on a 16:9 slide. Neither positions anything itself, so what you present is what you downloaded.

Picked by job, not by taste

Magnitude gets columns, trend gets a line, part-to-whole gets a donut. Eleven forms, each the right answer to a different question.

Typography

Set for the back row

Six fixed steps, sized against the tile they sit in — so a stat reads as a stat whether it fills a quarter of the slide or a sixth.

Length is enforced, not requested

Every field has a hard bound and a check for sentences that stop mid-thought. A slide that runs long is rejected and rewritten before you see it — asking a model politely to be brief does not work.

Colour

Data colours are never tile colours

Decorative fills are chosen to look right as large flat panels. Chart series are a separate set, validated for separation across colour-vision deficiencies in both light and dark themes.

Speed

Slides are filled in parallel

Once the outline exists, each slide is independent — so an eight-slide deck is roughly two round trips, not eight. They stream onto the canvas as they land.

02Three steps

From a sentence to something you can present

The whole loop takes about as long as it takes to write the prompt.

01

Say what the deck is about

One sentence is enough. Name the audience or the ask and the outline sharpens around it.

02

An outline is planned first

Slide count and archetype per slide, chosen for the argument — before a single tile is filled.

03

Present it, or take it with you

Full-screen presenter mode, or a .pptx whose text boxes and shapes are still editable.

03The catalogue

Ten layouts, each with a job

Every wireframe below is drawn by the same function that lays out your slides — including which tile carries the emphasis.

04Five themes

Re-theming never touches the words

A theme is a full token set — canvas, three surface tiers, five decorative fills and a separate validated chart palette. Switching one repaints the deck; it does not regenerate it.
