How to Make a Presentation With AI: The Complete 90-Minute Method [2026]

The presentation landed. The board approved her proposal.

Total time to make a presentation with AI from scratch? 87 minutes.

I’ve spent 24 years creating presentations at JPMorgan Chase, PwC, Royal Bank of Scotland, and Commerzbank. For most of that time, a decent presentation took a full day. Sometimes two.

Not anymore.

If you want to learn how to make a presentation with AI that actually works — without spending your entire weekend on it — you need a system. Not random prompts. Not AI gimmicks. A repeatable process that combines human thinking with AI speed.

Here’s the exact method I use with clients.

For the fundamentals of presentation creation without AI tools, see my complete guide: How to Make a Presentation: The Complete Guide.

Why AI Changes How You Make a Presentation

The average professional spends 4-8 hours creating a single presentation. Some spend entire weekends.

Here’s why learning to make a presentation with AI is a game-changer:

• First drafts in minutes — AI generates starting content instantly
• Structure suggestions — AI can propose logical flows
• Content expansion — AI fills in bullet points and speaker notes
• Editing assistance — AI helps simplify and clarify

But here’s what most people get wrong: AI can’t replace thinking.

If you don’t know your purpose and audience, AI will just help you make a presentation faster — but it won’t be a good presentation. Garbage in, garbage out.

The 90-minute method works because it combines human strategy with AI execution.

How to Make a Presentation With AI: The 90-Minute Method

This workflow uses AI tools (Copilot, ChatGPT, or Claude) to accelerate each phase. Set a timer. Each phase has a strict time limit.

Phase 1: The Decision Frame (10 Minutes) — Human Only

Before you touch any AI tool, answer four questions in writing:

1. What decision do I need from this presentation?
   Not “inform about Q3 results” but “approve the Q4 budget increase”
2. Who makes that decision?
   Name them. Understand what they care about.
3. What would make them say yes?
   What evidence, logic, or reassurance do they need?
4. What would make them say no?
   What objections will they have? Plan to address them.

Write your answers in 2-3 sentences each. This is your presentation’s foundation.

If you skip this step, the next 80 minutes will be wasted. AI will help you make a presentation faster — but it’ll be the wrong presentation.

Phase 2: The Narrative Spine (15 Minutes) — AI-Assisted

Now use AI to help create your presentation’s structure.

Use this prompt:

Review the AI output. Adjust the order if needed. You now have your narrative spine.

The test: Can you explain your presentation in 30 seconds using only these headlines? If not, ask AI to simplify the structure.

Phase 3: Content Generation (25 Minutes) — AI-Powered

Now — and only now — do you open PowerPoint or Google Slides. This is where AI dramatically accelerates how you make a presentation.

If you have Copilot in PowerPoint:

If you’re using ChatGPT or Claude:

For each slide in your structure:

1. Use AI to generate initial content
2. Review and edit (remove anything generic)
3. Move to the next slide

At the end of Phase 3, you should have a complete first draft.

Phase 4: Visual Refinement (20 Minutes) — Human-Led

AI can help you make a presentation quickly, but human judgment is still needed for refinement.

Go through each slide and apply these rules:

The One-Point Rule: Each slide makes ONE point. If you have two points, you need two slides.

The 6-Word Rule: No bullet point longer than 6 words. If it’s longer, ask AI to shorten it:

The Squint Test: Squint at your slide. Can you still tell what it’s about? If not, simplify.

Phase 5: The Polish Pass (15 Minutes) — AI-Assisted

Final refinements that separate good from great:

Opening check (3 minutes): Does your first slide create curiosity? Ask AI:

Flow check (5 minutes): Click through in slideshow mode. Mark any transitions that feel abrupt.

Closing check (3 minutes): Does your final slide tell the audience exactly what to do?

Spelling/grammar check (4 minutes): Run spell-check. Read titles aloud.

Phase 6: Speaker Notes (5 Minutes) — AI-Powered

Use AI to generate speaker notes for each slide:

You’re done. Total time: 90 minutes.

The Best AI Tools to Make a Presentation

Here’s what works best for different situations:

My recommendation: Use ChatGPT or Claude for Phases 1-2, then Copilot (if available) for Phases 3-6.

Common Mistakes When Using AI to Make a Presentation

Mistake 1: Skipping the Decision Frame. AI can’t read your boss’s mind. You need to define purpose and audience first.

Mistake 2: Using generic prompts. “Make a presentation about sales” gives generic results. Include your specific context, audience, and goals.

Mistake 3: Accepting AI output without editing. AI gives you a starting point, not a finished product. Always review and refine.

Mistake 4: Over-relying on AI for structure. AI suggests common structures. For high-stakes presentations, human judgment about what your specific audience needs is irreplaceable.

Mistake 5: Forgetting to fact-check. AI can make things up. Verify any statistics or claims before presenting.

FAQs: Making Presentations With AI

Can AI make a complete presentation for me?

AI can generate slides, but it can’t replace thinking. You still need to define your purpose, know your audience, and review the output. Think of AI as a fast assistant, not a replacement for strategy.

Which AI tool is best for PowerPoint?

Microsoft Copilot is best if you have it — it works directly in PowerPoint. Otherwise, use ChatGPT or Claude to generate content, then paste into PowerPoint manually.

How do I make AI output less generic?

Include specific context in your prompts: your industry, audience, their concerns, your company’s situation. The more specific your input, the more useful the output.

Is 90 minutes realistic for a good presentation?

Yes — for most business presentations. The method works because it eliminates time wasted on blank-page syndrome, template hunting, and rewriting. You focus only on what matters.
