AI presentation maker: decks from a prompt, done well

An AI presentation maker can turn a prompt into a full deck in a couple of minutes, and the good ones are worth using. The trick is to split the job in two. First ask for the argument as an outline, one sentence per slide, and fix it until it says what you mean. Then ask for the slides at 16:9, 1920×1080, with one idea each. Skip the first step and you get a tidy looking deck that does not say anything.

Start with the outline, not the slides

A presentation is an argument with pictures. If the argument is weak, design will not save it, and AI is very good at producing slides that look finished while saying very little. Ask for the outline in plain text first, read it aloud, and only move on when each line follows from the one before.

I am presenting to [audience] for [length] minutes.
What I want them to do afterwards: [one action].
What they already believe: [their starting point].

Write an outline of 8 to 12 slides.
Each slide: one sentence headline that states the point, not a topic.
Under each, list the one piece of evidence that proves it.
Do not invent numbers; write [figure needed] where data should go.

One idea per slide

Left alone, AI tools write slides like documents: a topic heading and six bullet points. The audience then reads instead of listening. Keep the screen for the headline and one piece of evidence, and move everything else into the speaker notes.

A useful instruction for the AI is: “Write the speaker notes as what I would say, and put on the slide only what the audience needs to see while I say it.” Ask it to move every bullet that fails that test into the notes. The slide gets lighter, the notes get better, and you stop reading from the screen. Visual hierarchy explains why one dominant element per slide works, and slides for public speakers covers talks rather than meetings.

Presentation slide sizes

Design at 1920×1080 unless you know the room has a 4:3 projector. If the deck will be shared on LinkedIn afterwards as a document or carousel, a few slides can be remade at 1080×1350 so they fill the feed. Video calls are 16:9 too, so a widescreen deck shared on screen fills the window without black bars, while a 4:3 deck arrives boxed in.

Make the deck look like yours

Generic templates are where AI decks give themselves away. A consistent background, your own fonts and one layout family across every slide do more for credibility than any animation. Presentation backgrounds covers what reads well on a projector, and for investor decks pitch deck design has its own rules.

In Gradiently, a deck is a design with several pages, each wearing your Mark, so every slide shares one background, and once you claim that Mark nobody else can export with it. Describe the presentation to the Designer and it asks what it needs, writes the words, lays out the pages in your brand kit's fonts and colours, and can make other sizes from them. The Mark keeps its calmest area behind each headline, so text reads even on a busy slide. Pro exports a PDF for sending or printing.

1. 1

   Approve the outline

   Use the prompt above in any assistant, or ask the Designer directly.

2. 2

   Generate the pages

   Ask for a 16:9 deck from the outline, one idea per slide, headlines as full sentences.

3. 3

   Replace placeholders

   Swap every [figure needed] note for a real number, chart or photo.

4. 4

   Rehearse from the slides

   If you need to read a slide to know what to say, it has too much on it, or too little in your notes.

5. 5

   Export

   PDF for sharing, or images for posting a few key slides as a carousel.

What to check in any AI deck

• Every number has a source you could name if asked.
• No slide has more than one point.
• Headlines read as a story when you read only the headlines in order.
• Charts are labelled in words, not just in a legend.
• The last slide says what you want the audience to do.
