Use AI To Draft Slide Decks Fast (So You Can Focus on the Story)

By Gerard Pietrykiewicz and Achim Klor

Achim is a fractional CMO who helps B2B GTM teams with brand-building and AI adoption. Gerard is a seasoned project manager and executive coach helping teams deliver software that actually works.

Here is an effective way to use an AI tool like Manus.im. Pick one shared task everybody hates, like building slide decks. Use AI to get to an 80% draft in minutes. Spend the saved time on decisions and conversations, not formatting. 

Takeaways

  • Start with one concrete use case, not a high-level concept or theory.
  • Use AI to get to a draft fast, then spend the free time on thinking and decisions.
  • Lead by example: show the workflow live so people feel the benefit.

Over the past few months, we’ve written about why AI adoption frustrates managers and how leaders can remove the barriers.

This time we want to stay close to the ground.

The real question is no longer “What’s our AI strategy?” It’s “What is the smallest thing I can do right now that actually helps my team?”

From “someday” to “right now”

Not that long ago, simple AI tasks were clunky (one could argue some still are).

You wrote a prompt, fixed the output, and still spent an hour or so cleaning it up.

That has changed.

Today, GenAI and tools like Manus can take you from a blank page to an acceptable first draft with no integrations and no scripts.

So instead of chasing a giant AI program across the whole company, start with one workflow everyone already knows and already dreads.

PowerPoint.

5 minutes to 80%

At some point, most of us have to create a slide deck. It’s repetitive work. It eats time. Most people do not enjoy doing it (or sitting through bullet-point hell).

Recently, Gerard has been running the following use case with his team.

1. Start with a single prompt inside Manus (you can grab the prompt here):

  • It tells the AI: You are a presentation builder.
  • It sets the basics: colours, fonts, spacing, logo use.
  • It asks for a complete deck: title slide, agenda, sections, conclusion, call to action.
  • It lets the AI decide the number of slides based on the content.

2. Then attach a document with the content and run the prompt.

3. In about five minutes, Manus spits out a fully structured deck with:

  • Clear sections
  • Logical pacing
  • Headings and subheadings
  • Simple diagrams and visuals in the right style

Is it perfect? No. 

Is it good enough to work with? Yes. Roughly 80% of the way there in fact.

  • Old way: hours tinkering in PowerPoint. 
  • New way: minutes to a working deck.

Comparison chart showing old way vs new way of building slide decks: left side hours spent formatting slides and little time for ideas, right side AI drafts slides quickly so most time is spent tightening the story.

Now you have oodles of time left to focus on fine-tuning the idea inside the deck instead of the deck itself.

What AI does (and what it doesn’t)

This is where expectations matter.

AI will not:

  • Make you a better presenter
  • Fix weak thinking in your source document
  • Turn a confused story into a sharp one

The quality of the presentation is still limited by your own tacit knowledge and the input you give it. If the document is vague or wrong, the deck will be vague or wrong.

What AI can do:

  • Give your idea a cleaner structure
  • Improve pacing from slide to slide
  • Remove a lot of low-value formatting work

AI gets you to a rough but usable version fast. You still need your tacit knowledge (those finite judgment calls in your head that never make it into documentation) to edit, refine, and present it well.

That last 20% is where your expertise shows up.

AI does not do that part for you (nor should it).

Why this is an adoption play, not a party trick

When AI adoption stalls, a lot of times it’s because we start too big.

We talk about agents and platforms that most people will never touch. Or we tell everyone to “go use AI” for random tasks like email summaries, then walk away.

Real adoption looks different.

It starts with one visible, repeatable use case that:

  • Everyone in the office recognises
  • Clearly saves time
  • Does not ask people to learn new tools or jargon

A slide deck generator does that:

  • Developers need decks to present ideas.
  • Product teams need decks for roadmaps.
  • Sales and marketing need decks for pitches.
  • Managers need decks for status updates and reviews.

When we see something like, “Watch this: five minutes from doc to deck,” we don’t just hear about AI. We feel the benefit.

Skepticism turns into curiosity.

Curiosity turns into “Can I try that with my next presentation?”

And that’s the point.

Effectiveness first, efficiency follows

It’s easy to treat this only as a time-saver.

But the point of a deck is not to have slides that act as a teleprompter. The point is to communicate an idea clearly enough that your team can act on it.

If AI takes the build time from two hours down to five minutes, the real win is what you now do with those 115 minutes you just freed up:

  • Pressure-test your idea with your team.
  • Rewrite weak arguments.
  • Plan the discussion, not just the slides.
  • Focus on decisions and next steps.
  • Brand the look and feel.

AI makes you more efficient at building the artefact.

Use that space to become “better at” the communication.

How to copy this in your team

You don’t need Manus specifically. Any solid AI tool works.

Here's the workflow:

  1. Pick a universal task. Decks work well because almost everyone creates them.
  2. Create one reusable prompt. Include your brand basics and the structure you want: title, agenda, sections, summary.
  3. Feed it real content. Use a proposal, a strategy doc, or a project brief.
  4. Time-box the run. Give yourself five minutes to generate, then move on.
  5. Spend the saved time on people. Use the deck to drive discussion, not to show off design.

Now you are not “playing with AI.”

You are changing how work gets done in a way your team can see and copy.

You’re helping your team become more efficient because they are more effective first. 

Final Thoughts

We didn’t include the full prompt here because it is long and specifically tuned for Manus.

If you want to give it a try using Manus, grab the free Google Doc here.

Feel free to share it and make it your own.

Again, the point here is not “magic words”. 

It’s the pattern: 

  • start small
  • pick a shared task
  • show a clear win
  • and let your team build on it

That’s how real adoption happens—one visible workflow at a time.
