ChatGPT won’t design beautiful slides for you, but it will do the part that takes the longest: the thinking, the structure, and the words. Here’s the step-by-step workflow and the prompts to build a presentation draft in well under an hour, then hand it to a design tool to make it look good.
Why slides eat so much of your week
Nobody puts “make a presentation” on their to-do list and feels good about it. You know the deck will take three hours you don’t have, and most of that time goes into staring at a blank slide trying to decide what the thing is even about.
You’re not imagining the time drain. Microsoft’s 2025 Work Trend Index found the average employee spends about 43% of their working time creating documents, spreadsheets, and presentations, and the other 57% communicating. [1] Decks sit right in the middle of that “creating” bucket, and they’re the format people procrastinate on most because they bundle three hard jobs into one: figuring out the argument, writing the words, and making it look decent.
Here’s the good news. ChatGPT, now used by more than 900 million people a week, [2] is genuinely good at the first two of those jobs. It won’t replace your taste or your design eye. But it will get you from “blank page” to “solid first draft” faster than anything else you’ve tried. Let’s get into exactly how.
What ChatGPT can and can’t do for a deck
Let’s be honest about the limits first, because that’s where most people get burned. ChatGPT is a text tool. It thinks in words, not in layouts. If you ask it to “make me a beautiful presentation,” you’ll get a wall of text that you still have to turn into slides yourself. That’s the disappointment a lot of people hit, and then they give up.
So split the job in two. ChatGPT does the thinking and the writing: the structure, the headlines, the talking points, the speaker notes. A design tool does the visuals: Gamma, Canva, PowerPoint with Copilot, or Google Slides with Gemini. When you keep those two stages separate, both get easier.
Use ChatGPT for the part that takes the longest (deciding what to say and saying it well), and a design tool for the part it’s bad at (making it look good). Don’t ask one tool to do both.
This is the same principle behind any good AI workflow: give the model a clear, specific brief and a job it’s actually suited to. If you want the deeper version of that idea, our guide on the 4-part prompt formula is the foundation everything below is built on.
The 6-step workflow
Here is the whole process at a glance. The rest of the article gives you the prompts for each step.
- Brief the model. Tell it your topic, audience, goal, and how long the talk is.
- Get the structure. Have it propose a slide-by-slide outline before writing a single word of content.
- Fill in the slides. Turn the approved outline into per-slide headlines and bullet points.
- Write speaker notes. Get a script for what you’ll actually say out loud.
- Move to a design tool. Paste the structured content into Gamma, Canva, PowerPoint, or Slides.
- Pressure-test it. Have ChatGPT predict the hard questions and tighten the weak slides.
Done properly, steps one to four take about twenty minutes. The design pass takes another twenty or thirty. That’s a presentable first draft in under an hour, instead of an afternoon.
The prompts (copy these)
Open these in any current version of ChatGPT. Swap the bracketed parts for your own details. Don’t skip the brief in Prompt 1, because every later step inherits it.
Prompt 1: the brief and the outline
You are helping me build a presentation. Before writing any content, propose a slide-by-slide outline. Topic: [what the talk is about] Audience: [who they are, what they already know, what they care about] Goal: [the single thing I want them to think, feel, or do by the end] Length: [number of minutes] which is roughly [minutes x 1.5] slides Tone: [e.g. confident and plain-spoken, no jargon] Give me a numbered list of slides. For each slide: a working title and a one-line note on its job in the story. Make sure there's a clear arc: a hook, the problem, the core idea, the proof, and a specific close. Don't write the slide content yet.
Why this works: forcing the outline first stops ChatGPT from generating ten samey content slides with no narrative. You get to approve the spine before you commit to the words. If a slide looks pointless, cut it now, not after you’ve written it.
Prompt 2: turn the outline into slide content
Great, I approve that outline with these changes: [your edits, or "none"]. Now write the content for each slide. For every slide give me: - A short, specific headline (not a label like "Introduction") - 3 to 5 tight bullet points, max 12 words each - One "say this, don't write this" note: a phrase I should speak but keep off the slide Keep the language concrete. Replace any vague claim with a specific example or number. Flag any statistic you include as [VERIFY] so I know to check it before I present.
That last line matters. AI will sometimes invent a tidy-sounding statistic. The [VERIFY] flag is your reminder to check anything numeric before it goes in front of an audience. Treat every figure as unconfirmed until you’ve seen the source.
Prompt 3: the slide-shrinker
This slide has too much text: [paste the slide] Rewrite it so the slide itself has no more than 6 words of headline and 3 bullets of 6 words each. Move everything else into a speaker note I can read from. The slide should make sense in 3 seconds from the back of a room.
Turning the outline into actual slides
Now you’ve got structured content. This is where you leave ChatGPT and bring in a tool that builds slides. You’ve got four solid options depending on what you already pay for.
Gamma is the fastest path. Paste your outline or content, and it generates a designed deck you can edit. It’s the closest thing to “type words, get slides.” Canva has a Magic Design feature that does the same and is great if your brand already lives in Canva. PowerPoint with Copilot can build a deck from a prompt or a Word doc if your company has Microsoft 365 Copilot. Google Slides with Gemini can generate draft slides and images from a prompt inside Workspace.
My honest take after testing all four with teams: Gamma gives the best-looking result with the least effort, but the output can feel a bit generic, so you’ll want to swap in your own colours and a real photo or two. Copilot and Gemini are convenient if you’re already in that ecosystem, but their auto-design is still a step behind Gamma. Whatever you pick, the deck only looks as good as the content you feed it, which is why the ChatGPT stage comes first.
After the design tool builds your deck, replace at least one text-heavy slide with a single image and one sentence. The contrast wakes the audience up, and it’s the easiest way to stop a deck looking machine-made.
Speaker notes and Q&A prep
The slides are only half the job. What you say while they’re up is the other half, and it’s the part people skip. ChatGPT is excellent here because speaker notes are pure text.
Prompt 4: the speaker script
Write speaker notes for each slide of this deck: [paste your slide content] For each slide, write 3 to 5 sentences in my speaking voice: natural, a bit conversational, no corporate filler. Include one transition sentence that leads into the next slide. Total speaking time should fit [X] minutes at a calm pace.
Prompt 5: the question predictor
Act as a sceptical member of my audience: [describe them, e.g. a budget-conscious finance director]. Based on this deck, list the 8 hardest questions I'm likely to get, ordered by how likely and how awkward they are. For the top 3, draft a 2-sentence answer I could give confidently. Point out any slide that's likely to trigger a tough question so I can pre-empt it.
Walking into a presentation having already rehearsed the three scariest questions is the difference between sounding prepared and sounding caught out. This single prompt has saved more than one client from a rough quarterly review.
Mistakes that make a deck look AI-made
People can smell an AI deck now, and it costs you credibility. Here’s what gives it away and how to fix each one.
- Every slide is the same shape. Title, three bullets, repeat. Break it up: a full-bleed image slide, a single big number, a quote. Variety reads as human.
- Generic stock language. Phrases like “leverage synergies” and “in today’s landscape” scream template. Ask ChatGPT to rewrite any slide “in plain English a smart 12-year-old would understand.”
- Unverified numbers. This is the dangerous one. Anything you didn’t personally confirm is a liability. The McKinsey research on AI at work is clear that the value comes from people using these tools with judgement, not blind trust. [3]
- No point of view. AI defaults to balanced and bland. Your deck needs a stance. Add one slide that says “here’s what I actually think” and watch the energy in the room change.
Writing is one of the most common things people bring to ChatGPT in the first place, [4] so the model is genuinely strong at this. Your job is to add the taste, the opinion, and the fact-checking it can’t.
What to do on Monday
Pick the next presentation on your calendar. Open ChatGPT, paste Prompt 1 with your real topic and audience, and get the outline. That’s it for the first session. Approve or fix the structure, then run Prompt 2 to fill it in. You’ll have a draft deck’s worth of content before your coffee’s cold.
Then move it into Gamma or whatever design tool you’ve got, spend twenty minutes making it yours, and run the question predictor before you present. If you want to get sharper at the prompting itself, the 4-part prompt formula will make every step above produce better output, and our walkthrough on using AI to analyse a spreadsheet pairs well when your deck needs to turn raw data into a clear story.
