AI can now turn a one-line prompt into a 15-slide deck in under a minute. The result usually looks polished and says almost nothing. Bullet points that could belong to any company, stock images of people pointing at whiteboards, and a “Next steps” slide with no actual steps.
You can make presentations with AI that are genuinely better, not just faster. The secret is using AI for the parts it’s good at, which are structure, first drafts and tidy design, while you supply the argument and the evidence. Here’s a workflow that does that.
Key takeaways
- To make presentations with AI that persuade, write the message before opening any tool.
- Ask for slide titles that are full sentences making one point each.
- Replace every placeholder number with real evidence.
- Use AI to rehearse by playing a sceptical audience member.
Tools that make presentations with AI
Your options fall into three groups:
- AI inside the slide app you already use: Copilot in PowerPoint with a Microsoft 365 Copilot licence, or Gemini in Google Slides on supported Google plans.
- AI-first deck builders such as Gamma, Canva‘s AI tools, or the slide features now built into assistants like Claude.
- General assistants used for the thinking, such as ChatGPT, Claude or Gemini, with the final slides built by hand.
For internal decks that need your company template, the first group is usually best. For quick external pitches where design matters more than branding, AI-first builders are fast. For high-stakes presentations, use a general assistant for the thinking and build the slides yourself.
Step 1: Start with the message, not the slides
Before you open any tool, write down in one or two sentences what you want the audience to believe or do afterwards. For example: “Approve a $40,000 budget to replace the ticketing system, because current delays cost us about 200 support hours a month.”
Then ask AI to stress-test it: “Here’s the main message of my presentation. Who is the audience: [finance director]. What objections will they raise, and what evidence would answer each one?” That list becomes your slide outline.
Step 2: Get a storyline before any design
Ask for an outline where each slide title is a full sentence that states the point, such as “Ticket delays cost 200 hours a month”, not “Current situation”. This is how consultants structure decks, and it works because someone reading only the titles gets the whole argument.
“Write a 10-slide outline for this presentation. Each slide title should be a complete sentence that makes one point. Under each title, list the evidence I’d need. Mark any evidence I haven’t given you as [NEED DATA].”
The [NEED DATA] tags stop the AI inventing numbers to fill gaps.
Step 3: Generate the slides
Now feed the approved outline into your slide tool. In PowerPoint or Slides, paste the outline and ask Copilot or Gemini to build slides from it using your template. In tools like Gamma or Canva, paste the outline and pick a theme.
Keep slides light. One idea per slide, a short headline, and a chart or image that supports it. If the AI produces walls of bullet points, ask it to “cut each slide to one headline and at most three short bullets, and move the detail to speaker notes”.
Step 4: Add your own evidence
Replace every placeholder number with real data. If you’re pulling numbers from spreadsheets, our guide to AI for Excel shows how to get summaries and charts you can trust. Remove any stock images that don’t add information. A simple chart of your own data beats a beautiful generic photo every time.
Step 5: Write speaker notes and rehearse
Ask the AI to draft speaker notes for each slide in your voice, about 60 to 90 seconds each. Then read them out loud and rewrite anything you wouldn’t naturally say. When you make presentations with AI, rehearsal is the step people skip and the one audiences notice. You can also ask: “Play the role of a sceptical finance director. Ask me the five hardest questions about this deck.” It’s a cheap rehearsal.
Common mistakes when you make presentations with AI
- Letting AI choose the message. It will pick the safest, vaguest one.
- Keeping invented statistics. AI deck tools sometimes add plausible numbers. Check every figure or delete it.
- Using too many slides. AI happily generates 25. Most meetings need 8 to 12.
- Ignoring your brand template. Off-brand decks look careless in front of clients.
- Uploading confidential data to a free design tool. Check our guide to AI privacy at work first.

Quick FAQ
What’s the best AI tool to make presentations?
If you need your company template, use Copilot in PowerPoint or Gemini in Google Slides. For quick, good-looking decks without a template, AI-first builders like Gamma or Canva are faster.
Can AI make a full presentation from a document?
Yes, most tools can turn a report into slides. Review the storyline and every number carefully, because automatic decks often miss the main point or simplify too much.
How long should an AI-made presentation be?
As short as your message allows. For a 30-minute meeting, 8 to 12 slides is usually plenty.
