# How to Make a Presentation with AI in 20 Minutes

> Make a work presentation with AI in 20 minutes: the exact prompts, a step-by-step timeline, and the checks that keep you from presenting a wrong number.

## How do you make a presentation with AI?

You make a presentation with AI by giving it the decision you need from the audience, your raw material (notes, numbers, an old deck), and a slide-by-slide structure, then asking it for an outline first and slide text second. Build the visuals last. In 20 minutes this breaks down to: 3 minutes to define the ask, 5 for the outline, 6 for slide content, 4 to build in a slide tool, and 2 to check numbers and prepare for questions. The AI drafts. You supply the facts and the judgment.

## TL;DR

- **Start with the decision you want**, not the topic. "Approve $40K for the pilot" gives AI something to build toward. "Update on the pilot" gives you a slideshow of facts.
- **Ask for the outline before any slide text.** Fixing a weak storyline takes 30 seconds. Fixing 12 finished slides takes the rest of your night.
- **Paste in your real material.** AI invents plausible filler when it has nothing to work from, and filler is how wrong numbers end up in front of executives.
- **Keep one idea per slide**, written as a full-sentence headline that states the point, not a label like "Q3 Results."
- **Check every number, name and date yourself** against the source. This is the one step you cannot hand off.
- **Use the AI to rehearse the hard questions** your boss or VP will ask. It is good at this and most people skip it.
- **Check your company's AI policy** before pasting anything confidential into a public tool.

## What do you need before you open an AI tool?

Gather four things. This takes three minutes and decides most of the quality of what comes out.

1. **The audience.** Who is in the room, what they care about, and how much they already know. "My VP and two directors, who know the project exists but not the details" is a good description.
2. **The decision or takeaway.** What should they approve, understand or do after you finish? One sentence.
3. **Your raw material.** Meeting notes, a spreadsheet export, last quarter's deck, an email thread, a draft memo. Messy is fine.
4. **The constraints.** Time slot (10 minutes means about 5 to 8 slides), required template, anything you must include or avoid.

If you cannot write the decision in one sentence, that is the real problem, and no tool will fix it. Spend the three minutes there.

A note on confidentiality: many companies restrict what employees can paste into public AI tools, and some provide an approved internal assistant. Use that one if it exists. If you are unsure, remove names, customer details and unreleased financials from what you paste, or ask IT before you start.

## What does the 20-minute timeline look like?

| Minutes | Step | Output |
|---|---|---|
| 0 to 3 | Define the ask, audience and material | A short brief |
| 3 to 8 | Generate and fix the outline | An approved slide-by-slide storyline |
| 8 to 14 | Draft slide content | Headline, 2 to 3 bullets, and a visual suggestion per slide |
| 14 to 18 | Build the slides | A formatted deck in your tool |
| 18 to 20 | Check and prepare | Verified numbers, speaker notes, likely questions |

## How do you make the presentation, step by step?

### Step 1: Write the brief (minutes 0 to 3)

Put your four inputs into one block of text. You will reuse it in every prompt, so write it once.

```
BRIEF
Audience: [who, what they know, what they care about]
Decision I want: [one sentence]
Time slot: [X minutes], so about [N] slides
Tone: [plain and direct / formal / upbeat]
Must include: [anything required]
Avoid: [anything sensitive or out of scope]
```

### Step 2: Ask for the outline only (minutes 3 to 8)

Paste your brief and your raw material, then use this prompt.

```
You are helping me prepare a work presentation. Here is my brief and my source material.

[paste brief]

SOURCE MATERIAL
[paste notes, numbers, old deck text, emails]

Task: propose a slide-by-slide outline for a [X]-minute presentation. For each slide give:
- A headline written as a full sentence that states the point
- One line on what the slide proves or explains
- Which part of my source material it comes from

Rules:
- Use only facts that appear in my source material. If you need a fact I did not provide, write [NEED: description] instead of making one up.
- Open with the decision I am asking for, then the evidence, then the next steps.
- Do not exceed [N] slides.
```

Read the outline like your VP would. Ask yourself three questions:

- Could someone who read only the headlines understand the argument?
- Is the ask on slide 1 or 2, not hidden on slide 9?
- Is anything in here that the audience does not need?

Then tell the AI what to change: "Merge slides 3 and 4. Cut the background slide, they know it. Add a risks slide." Do one or two rounds. Stop when the storyline holds.

Pay attention to every `[NEED: ...]` the AI flags. Those are the gaps in your case. Fill them from real sources or cut the slide.

### Step 3: Draft the slide content (minutes 8 to 14)

Once the outline is right, ask for the content.

```
Using the approved outline, write the content for each slide:
- Headline (the full-sentence version)
- 2 to 3 short bullets, maximum 12 words each
- A suggested visual (chart type with what it should show, simple diagram, or a single large number)
- Speaker notes: 2 to 3 sentences I can say out loud in plain language

Keep numbers exactly as they appear in my source material. Mark any number you calculated or rounded with (calculated). Do not add statistics from outside my material.
```

The "mark anything calculated" instruction matters. It tells you where to look first when you verify.

If you are presenting to executives, add: "Write for a reader who will spend 20 seconds on each slide." Executives scan. A slide that needs reading aloud to be understood is a document, and documents belong in the appendix.

### Step 4: Build the slides (minutes 14 to 18)

You have three realistic paths. Pick the one your company allows and you already know.

- **The AI built into your slide software.** Microsoft PowerPoint and Google Slides both offer AI assistants in some plans, and they can generate slides from a prompt or a document. The advantage is that your company template and brand fonts stay intact. Availability depends on your license, so check what you have.
- **A dedicated AI presentation tool.** Tools such as Gamma, Canva and Beautiful.ai generate a designed deck from an outline. They are fast and look polished, but you often need to rework the output to match a corporate template.
- **Paste into your existing template by hand.** It sounds slow, but with headlines and bullets already written, a 8-slide deck takes about four minutes. This is often the safest path for formal reviews, because your template is already approved.

Whichever you use, give the tool the approved slide content from Step 3, not the original topic. If you ask a design tool to "make a presentation about Q3 marketing results" it will write its own content, and you lose the work you just did.

For charts, build them from your actual spreadsheet. AI-generated charts from a description are illustrations, not data. If a slide needs a chart of real numbers, paste the real numbers into the chart tool yourself.

### Step 5: Check the facts (minutes 18 to 19)

Open your source material beside the deck and check, slide by slide:

- Every number matches the source. Look for transposed digits, wrong units (thousands vs. millions) and percentages that quietly changed base.
- Every name, title and date is right. AI sometimes "tidies" names.
- Every claim of cause ("sales rose because of the campaign") is something you can defend. AI loves to turn correlation into explanation.
- Nothing appears that was not in your material. Search for any statistic you do not recognize.

This is the step AI should not do for you. It cannot tell you which numbers are wrong, because it does not know your business. It can only compare text to text, and it is confidently wrong often enough to matter.

### Step 6: Rehearse the hard questions (minutes 19 to 20)

```
Here is my final deck content: [paste headlines and bullets]

Act as a skeptical [VP of Finance / director / CEO] who has 10 minutes and a budget to protect. List the 8 hardest questions you would ask me, ordered from most to least likely. For each, note which slide it relates to and whether my deck already answers it.
```

Pick the three you cannot answer and prepare a sentence for each. Put the best answers in a backup slide or in your speaker notes. Walking into a room already knowing what you will be asked changes how you present.

## What does a worked example look like?

Say you are a marketing manager presenting a quarterly campaign review to your VP, and you want approval to shift budget.

**Brief:**

```
Audience: VP of Marketing and two directors. They know we ran a spring email campaign but have not seen the results.
Decision I want: Approve moving [amount] from paid social to email for next quarter.
Time slot: 10 minutes, so 6 slides
Tone: plain and direct
Must include: cost per lead for both channels, one risk
Avoid: naming the agency we are not renewing
```

**Outline the AI might return:**

1. We are asking to move [amount] from paid social to email next quarter
2. Email produced leads at a lower cost than paid social this quarter
3. The gap held across all three segments we tested
4. Email's results depend on list quality, which is our main risk
5. The plan: what moves, when, and how we will measure it
6. Decision needed by [date] to hit the planning deadline

Notice what makes this work. Slide 1 is the ask. Each headline is a claim a director could argue with, which is exactly what you want in a room. Slide 4 puts the risk in before someone else raises it.

Say the AI flags `[NEED: cost per lead for paid social, Q2]` because you gave it only the email figure. You open your spreadsheet, find the number, and add it. Without the instruction to flag gaps, the AI would have produced a plausible number and you might not have caught it.

## What are the common mistakes with AI presentations?

- **Topic prompts.** "Make a presentation about our Q3 results" produces generic slides with invented content. Always supply the material and the ask.
- **Too many slides.** AI will happily produce 20. A 10-minute slot needs 5 to 8.
- **Label headlines.** "Budget Overview" tells the audience nothing. "Spend is 8% under plan, driven by delayed hiring" does. If the AI writes labels, ask it to rewrite them as sentences.
- **Bullets that repeat the speaker notes.** If the slide says everything you plan to say, people read ahead and stop listening. Keep the slide lean and the notes full.
- **Generic stock imagery.** AI-generated images of handshakes and glowing lightbulbs make a deck feel templated. A single big number or a clean chart is better.
- **Trusting the finish.** A polished deck looks credible whether or not the content is right. The design is not evidence.
- **Skipping the read-aloud.** Say the first three slides out loud. If a sentence is awkward to speak, rewrite it.

## Where should you not trust AI in a presentation?

Be careful in four places:

1. **Numbers and calculations.** Language models can make arithmetic mistakes and can misread tables pasted as text. Do the math in your spreadsheet.
2. **Outside facts.** Market sizes, industry benchmarks and competitor details may be outdated or invented. If you cite one, find the original source and link or name it.
3. **Sensitive judgment.** How to word a headcount change, a missed target or a disagreement with another team is your call. Use AI to offer options, then choose.
4. **Anything legal, regulatory or contractual.** Have the right owner review it.

## Can you reuse this for the next presentation?

Yes, and this is where the real time savings come from. Save your brief template and your three prompts in a note. Next time, you replace the audience, the decision and the source material, and the process takes 20 minutes or less. If you give the same update every month or quarter, keep last time's deck as source material and tell the AI: "Here is last quarter's deck. Update it with the new numbers below and flag every slide where the message changed."

## Could you stop rebuilding the same deck every month?

If you present the same numbers on a schedule (weekly pipeline, monthly spend, campaign results), the slide deck may be the wrong container. The work you repeat is gathering the numbers and rewriting the summary. With [Remy](https://goremy.ai), you can describe a small internal tool in plain English, such as a status page that holds your metrics, takes monthly updates through a simple form, and shows the current view at a live URL. Remy builds the full-stack app, and a typical first build takes about an hour. You then present from the page or share the link instead of rebuilding slides. Check with IT first if the data is sensitive, and note that Remy's usage cost is billed separately from its monthly plan.

## Frequently Asked Questions

### What is the best free way to make a presentation with AI?

Several tools offer free tiers or trials, and the built-in assistant in your slide software may already be included in your work license. The free option matters less than the process: a clear brief, an outline you approve, and your own source material. The same prompts in this post work in any general-purpose AI assistant, and you can paste the result into whatever slide tool you use.

### Can AI make a PowerPoint file directly?

Some tools can generate a slide deck and export it as a PowerPoint file, and PowerPoint itself has an AI assistant on some plans. Results vary, and generated decks often need reformatting to match a corporate template. Many people get better results by generating the content with AI and pasting it into their approved template.

### Is it safe to put company data into an AI presentation tool?

It depends on the tool and your employer's policy. Public consumer tools may handle data differently than an enterprise-licensed assistant. Check your AI policy, use the company-approved tool if one exists, and remove names, customer details and unreleased financials if you are unsure.

### How many slides should a 10-minute presentation have?

Five to eight is a good range, with one idea per slide. If you have more material, move it to an appendix and be ready to open it if someone asks. AI tends to produce too many slides by default, so set the limit in your prompt.

### How do I stop AI from making up numbers in my deck?

Paste in your real figures, instruct the AI to use only what you provided, and tell it to write `[NEED: ...]` when a fact is missing. Then verify every number against its source before you present. The instruction reduces the problem but does not remove it, so the final check is yours.
