ChatGPT Prompts for Pitch Decks That Work

The short version: ChatGPT is brilliant at the thinking part of a pitch deck, the story, the structure, the arguments, and useless at the design part, so use it to get your narrative and slide-by-slide content right first, then move to a slide tool. The prompts that work best are specific about audience, length and the question each slide needs to answer, not vague requests like "write me a pitch deck."

What ChatGPT is good for in a pitch deck

People ask ChatGPT to "create a pitch deck" and get back ten generic slides with headings like Problem, Solution, Market Size. Technically correct, completely useless, because every investor and client has seen that exact template a thousand times this month. What ChatGPT is good for is the bit before that: working out what your argument is, stress-testing it, and writing the words that go on each slide once you know the structure.

Think of it as a thinking partner for the content, not a designer. For the visuals you still need a real slide tool, or you build on top of the content with something like ChatGPT Slides once the words are right. Design software makes things look good. It cannot make a weak argument strong.

The prompt structure that produces usable output

Every bad ChatGPT pitch deck prompt makes the same mistake: it asks for the whole deck in one go. You get ten flat slides with no depth because the model has no idea who's reading them. Break it into three stages instead.

• Stage 1, the story: get the narrative arc right before any slide content exists
• Stage 2, the structure: turn the narrative into a slide-by-slide outline with one idea per slide
• Stage 3, the content: write the actual words for each slide, one at a time, with word limits

Doing it in that order takes maybe 40 minutes for a ten-slide deck. Doing it in one shot takes five minutes and produces something you'll throw away.

Stage 1 prompt: build the narrative

Copy this and fill in the brackets:

"I'm pitching [who, e.g. a seed investor / a corporate client / a conference audience] on [what, one sentence]. The outcome I need is [specific ask, e.g. a £200k investment / signing a 12-month retainer / a yes to a pilot project]. Before you write any slides, ask me five questions about the problem, the audience's current alternative, and why now is the moment, so we can build a sharp argument together."

That last line matters. Asking ChatGPT to interrogate you before it writes anything forces out detail you'd otherwise skip, and it stops you getting a generic answer back.

Stage 2 prompt: the slide-by-slide outline

Once you've answered its questions, run this:

"Based on everything above, give me a 10-slide outline for this pitch deck. For each slide, give me the slide title and a one-sentence note on the single idea that slide needs to land. No slide should try to make two points. Flag any slide where you think the argument is weak."

That final sentence is the one most people skip, and it's the one that earns its keep, because ChatGPT will tell you where your logic has a gap if you ask it directly.

Stage 3 prompt: write the actual slide copy

Go slide by slide, not all at once:

"Write the content for slide 4, [title]. Maximum 25 words of body text plus one headline of 8 words or fewer. This slide needs to make the audience feel [specific emotion or realisation], not just inform them. Write three versions, ranging from safest to boldest."

Word limits are the whole trick here. Without them ChatGPT writes paragraphs, and nobody reads paragraphs off a screen behind you while you're talking.

A worked example: pitching a subscription box service

Say you run a small subscription box business selling curated skincare from independent UK brands, and you're pitching a wholesale buyer at a mid-size retailer for a six-month trial stocking arrangement. Here's how the three stages play out.

Stage 1, you tell ChatGPT the ask is a six-month trial in 40 stores, and it asks you back: what's the buyer's current alternative (they stock three big-name brands already), why now (two of those brands just had a supply issue), and what does the buyer get paid on, margin or footfall. Answering those questions reshapes the whole pitch away from "our products are lovely" toward "we solve your supply reliability problem and we're currently 8 points higher margin than your existing suppliers."

Stage 2 outline comes back with ten slides, and ChatGPT flags slide 6 ("Our Growth") as weak because you don't have retail growth numbers yet, only direct-to-consumer ones. That flag alone saves you from an awkward question in the room.

Stage 3, you write slide 3, "Why Now," with a 7-word headline ("Your supplier gap is our opening") and 22 words of body text about the specific margin difference. Three versions, you pick the boldest one because the buyer you're pitching is known for liking directness.

None of that came from asking ChatGPT to "write a pitch deck for my skincare business." It came from forcing specificity at every stage.

The uncomfortable bit nobody tells you

ChatGPT will happily write you a deck that sounds persuasive and is wrong about your market. It doesn't know your competitors' actual pricing, it doesn't know what that specific investor funded last quarter, and it will invent plausible-sounding market size figures if you don't give it real ones. I've seen decks (not mine, from people I've talked shop with) where the "£4.2 billion market opportunity" slide was pure invention, lifted from a model guessing at a number because the prompt didn't supply one. Every statistic in your deck needs to come from you or a source you've checked, never from the model's guess. Treat ChatGPT as a brilliant editor and structurer, never as a research assistant for numbers that matter.

The other uncomfortable truth: a tighter, plainer deck almost always beats a cleverer one. People ask for "persuasive" language and end up with corporate waffle. The best prompt addition you can make to any of the above is simply: "Now rewrite that and cut every word that isn't doing work."

Prompts for specific slide types

Some slides need a different approach because they're doing a different job.

• The problem slide: "Write the problem slide as a specific scenario involving one named type of customer, not a general statement about the market. Make it concrete enough that someone could picture it happening."
• The competition slide: "List our three real competitors [name them] and write one honest sentence on where each one beats us. Don't pretend we win on everything, that makes the slide less believable."
• The ask slide: "Write the final ask slide. State the exact number, what it buys, and the single next step you want the audience to take within 48 hours."
• The objection slide: "What are the three objections this specific audience is most likely to raise, and write one line answering each before they ask."

That competition slide prompt is the one people flinch at, because admitting a weakness feels risky. It's the slide that makes the whole deck more credible, because a deck claiming total superiority reads as either naive or dishonest.

Moving from content to visuals

Once your slide content is locked, decide where it goes. If you want to stay inside ChatGPT, tools built on top of it can turn content into formatted slides, which is worth reading about in this walkthrough on building a deck with ChatGPT Slides. If you'd rather compare how Claude handles the same job, there's a separate approach covered in these Claude prompts for presentations, and the two tools produce different outputs from similar prompts, worth testing both before you commit to one workflow.

For imagery, don't use stock photos if you can avoid it, investors and buyers have seen the same five handshake photos a thousand times. If you need custom visuals, Midjourney prompts for business images will get you something distinctive for a fraction of what a designer charges, and if you want to loosen up an opening or closing slide with something more human, the same logic that works for turning a photo into a cartoon with ChatGPT can work for a lighter team slide, though use that sparingly in a formal investor deck.

A note on volume and timing

A ten-slide investor deck should take you roughly 90 minutes end to end using this method: 20 minutes on the narrative conversation, 15 on the outline, 45 on slide-by-slide copy, 10 on a final cut pass. If you're pitching regularly as part of wider business development work with ChatGPT, build yourself a saved prompt template for stage 1 so you're not retyping the same framing every time. The time you save compounds fast once you're sending three or four pitches a month.

Frequently asked questions

Can ChatGPT write a whole pitch deck for me?

It can write the words for every slide, but it cannot design the slides or supply accurate market data, so treat it as a content and structure tool and build the visuals separately in a slide tool or a dedicated AI slide builder.

What's the biggest mistake people make with ChatGPT pitch deck prompts?

Asking for the entire deck in one prompt without giving audience, ask, or word limits, which produces generic ten-slide templates that read exactly like every other AI-written deck an investor has already seen this year.

Should I trust the statistics ChatGPT puts in a pitch deck?

No. Never use a market size, growth rate, or competitor figure from ChatGPT without checking it against a real source first, because the model will generate a plausible-sounding number rather than tell you it doesn't know.

How long should a ChatGPT-assisted pitch deck take to build?

Roughly 90 minutes for a ten-slide deck if you work through narrative, outline, and slide-by-slide copy in three separate stages rather than asking for everything at once.
