How do you make a presentation with AI?

Building slides by hand means three jobs at once: deciding what to say, wording it, and making it look good. AI tools can now take a large share of the second and third jobs. The first one, deciding what your audience needs to hear, is still where a good presentation is won or lost, and it is the part to keep firmly in your own hands.

Two kinds of tools do the heavy lifting. Dedicated AI slide tools such as Gamma start from a short description or a pasted text, propose an outline you can edit, let you pick a visual theme, and then generate the slides; finished decks can be shared by link or downloaded as PDF or PowerPoint files. AI inside familiar software is the other route. Microsoft's Copilot can create a PowerPoint presentation from a chat-style request or from an existing Word document. Businesses get it with Copilot for Microsoft 365, and since January 2024 individuals can add it with Copilot Pro, a $20-a-month subscription that works alongside a Microsoft 365 Personal or Family plan.

Pass 1: Build the outline in a chatbot

Slide tools produce better decks from a clear outline than from a vague topic. Start in ChatGPT, Claude or Gemini, and give it your real material.

I'm presenting to our town council next week: 10 minutes, then questions.
Goal: get approval for a 6-month pilot of a free library e-bike loan program.
Audience: 7 councillors, practical, worried about cost and liability.
My material: [paste your notes, budget table and the survey summary].

Write a slide-by-slide outline of no more than 9 slides.
For each slide: a headline that states the point as a full sentence,
up to 3 short supporting bullets, and a suggestion for one visual.
Use only figures from my material. Put open questions at the end.

Read the outline as if you were a councillor. Is the request on slide 1 or slide 9? Are the cost and liability worries answered before anyone has to ask? Fix the order and the headlines now; changing a sentence here is far cheaper than redesigning six slides later.

Pass 2: Turn the outline into slides

In Gamma: start a new AI-generated presentation and give it your outline rather than a one-line topic. Review the outline it proposes, merge or delete slides, choose a theme, and generate. The draft usually appears within tens of seconds.

In PowerPoint with Copilot: open a new presentation, open Copilot, and ask it to create a presentation from your outline; if your notes are already in a Word document, you can ask Copilot to build the deck from that file instead.

Either way, you now have something that looks finished. It isn't yet.

Pass 3: The design and fact pass

The $4,200 figure above is illustrative; use your own. Pay special attention to anything the tool added on its own, such as a statistic, a quote or a chart you did not supply. Microsoft itself warned when it introduced Copilot that the system will sometimes be wrong, and the same applies to every generator. Delete any claim you cannot trace to your material.

How do you keep it from looking generic?

Generic decks come from generic inputs. A tool given only "e-bike library program" can only offer what an average presentation on that subject looks like. The outline prompt above already helps, because it carries your audience, your goal and your figures. Add your own voice in the speaker notes and headlines, too: the specific street, the actual survey comment, the question a councillor asked last month.

Then replace the defaults. Swap the theme's stock images for your own photos, such as the real library entrance, the bike rack, your team. Use your organization's template, logo and colors rather than the tool's built-in theme. Turn at least one bullet list into a real chart made from your data, which no template can supply.

Finally, cut. AI drafts tend to fill every slide evenly and add filler slides like "Introduction" and "Overview." Remove anything that does not move the audience toward your decision, and leave white space. A presentation with seven sharp slides built on your own facts and pictures will not look like anyone else's, whichever tool produced the first draft.
