AI for presentations: from outline to slides without the filler

Decide what the deck is for before you open a slide tool

Most bad decks fail before the first slide: the presenter did not know what they wanted the room to do afterward. AI cannot fix that, but it is very good at forcing the question.

Answer three things in writing. Who is in the room, and what do they already believe? What should they decide or do when you finish? What is the one sentence you want them to repeat to someone who was not there?

Then hand those answers and your raw material to a chat assistant and ask for the story, not the slides:

You are a presentation coach who has helped people pitch to skeptical executives. Help me structure a talk, not design slides.

Audience: [WHO IS IN THE ROOM AND WHAT THEY CURRENTLY BELIEVE]
Goal: [WHAT I WANT THEM TO DECIDE OR DO AFTERWARD]
Time: [MINUTES], including questions
Raw material: [PASTE NOTES, DATA, MEMO, OR PRIOR DECK TEXT]

Produce:
1. The one sentence the audience should repeat afterward. Offer three candidates and recommend one.
2. A three-to-five-point argument that earns that sentence, in order, with the evidence from my material that supports each point. Where my material has no evidence for a point, say so.
3. What to cut: anything in my material that does not serve the argument.
4. The two objections this audience is most likely to raise, and where in the argument to address them.

Use only my material for facts. If my material is too thin to structure, ask me up to five questions first.

Three story shapes cover most work presentations. Situation, complication, resolution: where we are, what changed, what we should do. Problem, options, recommendation: for decisions. Before, after, how: for proposals and product pitches. For status updates, skip the drama and use headline, evidence, ask.

Turn the outline into a slide plan

Once the argument holds, ask for a slide-by-slide plan, and insist on one rule: every slide headline is a full sentence that states the takeaway. "Q3 results" is a label; "Q3 revenue grew while margin fell, because of freight" is a headline. If a reader flipped through only the headlines, they should get the whole argument.

Ask for a table with four columns: headline, evidence on the slide, suggested visual, and the gist of what you will say. Aim for one idea per slide and roughly ten to twelve slides for a twenty-minute talk. Three rows for an internal proposal:

Every number in that table comes from the presenter's own material. That is the point of doing the plan before the tools: the tools will fill any gap with something plausible.

Drafting slides: the tools

Gamma

Gamma turns a pasted outline or document into a designed deck in about a minute, in a card-based editor that reflows content so nothing overflows. Select a card and ask it to shorten, change tone, add an image, or build a chart from pasted numbers. It exports to PowerPoint and PDF, with some loss of layout. Best for internal decks, proposals, and training material where speed beats brand precision. Paste your slide plan, not a one-line topic; the difference in output is dramatic.

Copilot in PowerPoint

With a Microsoft 365 Copilot license, Copilot can create a presentation from a prompt or from a Word document, on your organization's template, and then rewrite or condense text, organize the deck into sections, and summarize it. In current versions the decks it creates come with draft speaker notes. Output is uneven and usually needs cleanup, but it keeps you inside the corporate template and file format, which is what most companies require.

Gemini in Google Slides

On Workspace plans that include Gemini, the side panel in Slides can draft a slide from a prompt, generate images, summarize a deck, and pull from files in Drive. It is the natural choice for teams that live in Google Workspace. Check the vendor's current documentation for what your plan includes.

Canva

Canva is for when the look matters. Magic Design produces a presentation from a prompt or an uploaded document, Magic Write drafts and rewrites text in place, Magic Media generates images, and a brand kit keeps everything on-color. Magic Switch turns a deck into a document for the people who want to read instead of watch.

The chat assistants

ChatGPT and Claude are where the thinking happens: story, headlines, notes, tightening, rehearsal. Both can also produce a basic PowerPoint file from an outline; check the current feature list for your plan.

Speaker notes that are not the slide read aloud

The slide carries the claim and the evidence. The notes carry what you say about them: why it matters, the story behind the number, the transition to the next point. When both say the same thing, you end up reading your slides to people who can read.

You are a speechwriter for a plain-spoken presenter. For each slide below, write speaker notes I can say in 60 to 90 seconds.

Rules:
- Do not restate the headline or read the bullets. Add what the slide cannot show: context, one concrete example, why it matters to this audience.
- Start each slide's notes with a sentence that is not the headline.
- End each with a one-line transition to the next slide.
- Conversational, first person, short sentences. No jargon the audience would not use.
- Use only my material. Where I have not given you an example, write [EXAMPLE NEEDED] and move on.

Audience: [WHO]
Slides (headline, then bullets, one slide per block):
[PASTE SLIDE TEXT]

Then make the notes yours. Swap in the example you actually lived, cut anything you would not say out loud, and read every slide's notes with a timer. If a slide takes three minutes, it is two slides.

Tightening the deck

Paste the full slide text into a chat assistant and ask, one at a time:

• "Which slides make the same point? Recommend which to merge or cut."
• "Rewrite every headline as a full-sentence takeaway. Keep the meaning; do not add claims."
• "Cut the words on each slide by a third without losing any claim or number. Show before and after."
• "List every number in this deck with the slide it appears on. I will check each against its source."
• "If the audience only read the headlines, what would they conclude? Where does the argument break?"

That last one catches the slide that is there because you worked hard on it, not because it belongs. Delete it. Every deck the audience remembers is shorter than the one the presenter started with.

Images: where AI helps and where it hurts

Image generation is good for conceptual illustrations, section dividers, backgrounds, and icons, and Napkin AI is useful for turning a paragraph into a diagram. Canva, Adobe Firefly, and Midjourney all produce usable slide imagery; Adobe says Firefly is trained on licensed and public-domain content, which is why it is a common pick for commercial work.

The cautions matter more than the tools:

• Never generate a chart, a map, or anything with numbers. Image models draw the shape of a chart, not your data. Charts come from your spreadsheet, in your slide tool.
• No logos, trademarks, or product screenshots. A fake screenshot in a customer deck is a credibility problem and sometimes a legal one.
• No real people, and no "in the style of" a living artist. Use photos you have rights to, or a described generic scene.
• Text inside generated images is unreliable. Add labels in the slide tool instead.
• Keep one visual style. Six images from six prompts look like six decks. Set a style phrase and reuse it.
• Check the terms and your policy. Some organizations require disclosure of AI-generated images in external material, and rights vary by tool and plan. See AI and copyright at work.
• Prefer the real thing. A photo of your actual warehouse beats a generated one every time.

Rehearsal prompts

The cheapest rehearsal is a hostile audience that never gets tired.

You are the most skeptical person in my audience: [ROLE, E.G. A CFO WHO HAS SEEN THREE FAILED IT PROJECTS]. I will paste my slide headlines and speaker notes.

1. Ask me the five hardest questions you would ask, in the order they would come up during the talk.
2. Name the weakest slide and say why.
3. Point to the exact moment a skeptic stops trusting me, and what would fix it.
4. For each question, draft a two-sentence answer using only my material, and flag any question my material cannot answer.

Deck:
[PASTE HEADLINES AND NOTES]

Follow it with two more passes. Ask for a five-minute version of the talk; if the five-minute version works, your argument is sound. Then read the notes aloud to the assistant's voice mode, where your plan offers one, and have it play the audience for questions. It will not replace a colleague, but it will find the slide where your explanation wanders.

Worked example: a fifteen-minute budget request

An operations manager needs approval to replace the handheld scanners in a distribution center. Her raw material: a two-page memo she wrote for her boss, the vendor's quote, and an export of picking-error data from the warehouse system.

She runs the story prompt with the audience set to "a finance director and a VP of operations who think the current scanners are fine." The assistant offers three candidate sentences; she picks "the scanners are now the biggest cause of picking errors, and replacing them costs less than the errors." It flags that her memo has no evidence for the cost per error, so she pulls that number from her own records before going further.

The slide plan comes back at eleven slides. She cuts two that repeat the problem. She builds the deck in PowerPoint with Copilot from her memo on the company template, replaces its generic bullet slides with her own three tables, and makes the one chart from her spreadsheet. The notes prompt gives her a first draft of what to say; she rewrites slide four around the day a scanner failed mid-shift, because she was there.

The hostile-audience prompt asks "why not lease?" and "what happens to error rates if we just retrain?" She had an answer to neither, so she adds a slide comparing lease and purchase and a line in her notes about the retraining that was already tried. In the room, the finance director asks about leasing first. Whether the request is approved depends on the numbers; the rehearsal made sure the numbers were the only thing left to argue about.

A note on confidentiality

Decks hold the things companies protect: financials, customer names, roadmaps, pricing. Draft them in the tools your organization has approved, and never paste confidential material into a consumer AI tool unless your organization has approved it. Gamma and Canva share by link; check who can open the link before you send it, and turn off public access for anything internal.
