Build a first-draft slide deck with AI

by paul thomas·4 min·1,007 wordsSKILL-GUIDE

Most people approach a new presentation the wrong way: they open PowerPoint or Slides and start making slides. AI doesn't fix that habit. It just speeds up the sprawl.

The better approach is to get the story right before you touch a single slide. AI is very good at that part.

The tool, and how to set it up

Use Claude for the thinking work: structuring the narrative, writing slide headlines and supporting points, drafting speaker notes. Claude handles long documents well, follows complex structural briefs, and will tell you when the argument doesn't hold together.

For actually generating slides, tools like Gamma, Beautiful.ai, or Copilot in PowerPoint can take a text outline and produce a designed deck. They are useful for a visual starting point. The final design, template compliance, and brand alignment still need a human. AI is strong on structure and words. It is weak on knowing what your audience expects to see, how your slides should look, or what your brand forbids.

Paste your document or outline directly into Claude. If you are using Claude.ai or the API, there is no meaningful setup required. Attach a file or paste the text, then run the prompt below.

How to do it

1. Start from something, not nothing. Paste your existing document, meeting notes, or rough outline into Claude. A blank brief ("make me a deck about X") produces generic slides. Your raw material, even if messy, gives AI something to work with and keeps the output anchored to what you actually know.

2. Get the story first. Before asking for slide content, ask Claude to identify the narrative arc: what is the core argument, what is the ask, and what evidence supports it. Review this before moving on. If the story is wrong at this stage, the slide structure will be wrong and you will spend time polishing something that does not work.

3. Ask for a slide-by-slide structure, one idea per slide. Request a plan where each slide has: a short, assertive headline (one claim, not a topic label), up to three supporting points, and a speaker note that covers what you would say aloud. This format forces discipline. If a slide needs more than three points, it is covering more than one idea. Split it.

4. Tighten wordy slides. Paste back any slides you have drafted and ask Claude to cut them to one sentence per bullet and tighten the headline to a single claim. This is one of the highest-value uses of AI in deck work. It will do in seconds what takes most people twenty minutes of reluctant editing.

5. Generate talking points. Once the slide structure is agreed, ask for a set of spoken talking points per slide, written in plain language and calibrated to your audience's level of familiarity with the topic. These go into your speaker notes and form the basis of your rehearsal.

The prompt

I am building a slide presentation. Below is my source material [paste document or outline here].

Please do the following:

1. Identify the core argument or ask of this presentation in one sentence.
2. Propose a slide-by-slide structure. For each slide, give me:
   - A short headline that makes one clear claim (not a topic label)
   - Up to three supporting points (one line each)
   - A speaker note (two to three sentences covering what I would say aloud)

Aim for [X] slides. The audience is [describe audience and their level of knowledge]. The presentation ends with [describe the ask or intended outcome].

After the structure, flag any slides where the argument feels weak or where I am missing supporting evidence.

Fill in the bracketed sections before running. The final line asking for weak spots is worth keeping: it gives you an early warning before you invest time in design.

How to QA it

Read the deck end to end as a narrative, not as a list of slides. Ask: does each slide build on the last? Does the argument earn the ask by the end? If the structure jumps or the logic is circular, fix that before writing any copy.

Check every fact, number, and claim. AI will reproduce figures from your source material, but it may also introduce plausible-sounding numbers that were not there. Anything that goes on a slide in front of an audience needs to be traceable back to a source you have seen.

The two most common failures are: a deck that is well-structured but says nothing specific (the argument is hollow), and slides that are over-packed because the one-idea-per-slide rule was ignored. Both are fixable at review stage if you are looking for them.

Verify that each slide headline is a claim, not a topic. "Q4 Results" is a topic. "Q4 revenue grew 18% despite reduced headcount" is a claim. Topic-label headlines are a tell that the slide has not been thought through.

How to stay safe

Keep client data, commercially sensitive figures, and personal information out of consumer AI tools. If your deck contains anything you would not send to a third-party consultant, do not paste it into a consumer chat interface. Use an enterprise-licensed deployment where your organisation has data processing agreements in place.

Verify every number before it appears on a slide. AI-generated or AI-reproduced statistics feel authoritative. They are not. If you cannot find the original source for a figure, remove it or replace it with something you can substantiate.

Follow your organisation's brand guidelines for slide templates, font use, and logo placement. AI tools generate visual layouts that will almost certainly not match your template. Treat AI-generated design as a wireframe, not a finished product.

If you are presenting externally, check whether there are any disclosure requirements for AI use in your sector or client relationship.

Start with a presentation you already need to make. Paste the brief or notes, run the prompt, and compare what comes back against your own instinct for the story. That gap is where the real work is.
