How to Make a Presentation with AI (Without It Showing)

An AI can produce a twenty-slide deck in about a minute. Whether that deck survives ten minutes in front of an audience is a different question. Here's how to get one that does.

Step 1: Prompt with an argument, not a topic

This is where most decks are won or lost.

Weak: "Make a presentation about our Q3 results." Strong: "Make a 12-slide deck arguing that we should shift Q4 budget from paid ads to content, for our leadership team, who are skeptical about content's payback period."

The second prompt contains an audience, a position, a length, and an objection to address. You get a deck with a spine instead of a Wikipedia summary.

Step 2: Hand it your real numbers

Never let a generator supply your metrics. Paste in the actual figures — revenue, retention, timelines — as part of the prompt, and tell it to use only those.

This is the difference between a deck that gets you a decision and one that gets you caught. If a tool fills a stat-shaped hole with an invented number, the whole deck's credibility goes with it.

Step 3: Demand assertion titles

Ask explicitly for slide titles that state the takeaway. "Content CAC fell 40% while paid rose" is a title. "Marketing Metrics" is a label.

A reader who only scans your titles should get the entire argument. This one instruction upgrades a generated deck more than any design change.

Step 4: Fact-check every claim that isn't yours

Go through the deck and mark each factual claim. For each one: is it your data, is it sourced, or did it appear from nowhere? Delete or verify anything in the third category. Tools that ground claims in real sources and include a sources slide make this fast; tools that don't make it essential.

Step 5: Cut a third of the slides

Generated decks are always too long — they cover the topic rather than making the case. Remove anything that doesn't advance the argument. Twelve tight slides beat twenty thorough ones.

Step 6: Write or fix the speaker notes

The notes should say what you'll say, not repeat the bullets. If the tool generated notes, read them — generic notes are worse than none, because you'll rely on them and find nothing there.

Step 7: Rehearse against the slide titles only

Present from the titles alone once. If you can't make the argument flow from title to title, the structure is wrong — fix the order before you polish the design.

What to look for in a tool

The features that matter for a deck you'll actually present: grounded, sourced claims, assertion-style titles, real speaker notes, and consistent design. Brainbaby's presentation maker researches the topic before writing, states takeaways in titles, and closes decks with a sources slide — which removes most of step 4. Make a presentation free →

FAQ

Will people know my deck was AI-generated? Not if you did steps 1, 2, and 5 — a specific argument, your real data, and a ruthless edit. Generic decks give it away; edited ones don't.

What's the biggest risk? Invented statistics. It's the failure that damages your credibility rather than just your design.

How long should a deck be? Fewer slides than the AI gives you. Aim for one idea per slide and cut anything that doesn't move the argument.

Can I use it for investor pitches? As a first draft, yes. Investor decks need your real numbers and your own narrative judgment — treat AI as the structure, not the substance.
