Generating a corporate presentation with AI without ending up with generic slides

Why does a deck built in thirty seconds look as though it could belong to any company on earth?

You have seen the result. You describe your subject to a generator, ten slides come back, clean and structured, and you feel a particular mix of admiration and unease. Nothing in it is wrong. Nothing in it is yours.

The reflex is to blame the tool. That is rarely the right explanation. A generic presentation is almost always the faithful rendering of a generic request, and the room for improvement lies in what you give the machine, not in the machine.

Why the output is generic

A presentation generator fills gaps. That is its function, and it is also its trap.

Ask for "a presentation on our 2027 commercial strategy" and the tool has three pieces of information: a topic, a year, a register. Everything else is missing: your market, your numbers, your audience, what you want out of the room. The machine fills those gaps with what it knows best, which is the average. A plausible structure, catch-all headings, statements true for everyone and therefore useful to no one.

The result is not wrong. It is interchangeable. And on corporate material, interchangeable is the one disqualifying flaw: it signals that nobody thought about it.

The four inputs that determine the output

There are exactly four things to supply. None is optional, and their absence shows in the order they are listed.

1. The template

The most concrete input, and the most often forgotten. Without your PowerPoint template, no tool can produce something that looks like you. It will produce something that looks like itself.

A good template is a current master, with properly defined layouts, your theme colours and your fonts, rather than a file of attractive slides. If your internal template is patched together, the output will be patched together whatever the tool. That is a subject in its own right, covered in our article on how AI breaks brand guidelines.

2. The raw material

This is what separates a corporate document from a school exercise.

Your quarterly figures, your meeting notes, the minutes of the last committee, last year's deck, the framing note your director wrote. These elements, and only these, make a presentation impossible for a competitor to reproduce.

The useful habit: do not summarise before you supply. Many people condense their sources into three lines before handing them over, in the name of clarity, and delete exactly what would have made the result specific. Give the raw material; filtering is the work you are delegating.

3. The intent

Two questions, and they change everything: who is in the room, and what do you want from them?

"Present the commercial plan to the executive committee to get three budget trade-offs approved" and "present the commercial plan to the sales team so they own the targets" produce two documents with different lengths, different densities and different registers. A generator that ignores the distinction will produce the lowest common denominator of the two.

4. The constraints

The slide count. The length of the session. The subjects to avoid. The confidentiality level. The figures that must not leave the room.

Constraints are usually perceived as restrictions; they are in fact information. "Twelve slides maximum, twenty minutes, do not mention the ongoing dispute" says more about your situation than three paragraphs of context.

The brief: before and after

The difference is easy to see on an example.

Generic brief:

"Make me a presentation on our third-quarter results."

Brief that works:

"Pack for the executive committee on 24 September, 20 minutes, 12 slides maximum, on the attached template. Objective: get approval for repricing range B and for pushing project Atlas to Q1. Audience: CEO, CFO, sales director. They know the context, get to the point. Material attached: the Q3 margin workbook, the minutes of the 2 September steering committee, the Q2 deck. The supplier dispute must not appear. Every findings slide must carry an explicit recommendation."

The second brief is not longer for the sake of it. Every sentence removes a decision the machine would otherwise have taken for you, and would have taken on average.

What to cut: the best-documented principle

Once the deck exists, the instinct is to add. An illustrative diagram, a quotation, a context slide. The opposite is almost always right, and it is one of the most firmly established findings in research on multimedia learning.

Richard Mayer's coherence principle states that people learn better when extraneous words, pictures and sounds are excluded rather than included. This is not a designer's opinion: the principle was supported in 23 out of 23 experimental tests, with a median effect size of 0.86. In the social sciences, an effect of that size replicated that consistently is rare.

The neighbouring signaling principle adds that people understand more deeply when cues highlight the organisation of the essential material. Fewer elements, then, but a more explicit hierarchy.

Translated into practice on a generated deck:

• The context slide nobody asked for: cut it.
• The decorative image with no informational function: cut it.
• The diagram that repeats what the text says: cut it.
• The topic title: replace it with an assertion.

A twelve-slide deck that holds up beats a twenty-slide deck where eight slides are padding, and it is produced faster.

Iterating: correct by intent, not slide by slide

One last point of method, and it is the one that saves the most time.

The reflex is to go through the deck slide by slide, by hand. That is the slowest and least stable approach: every manual edit risks drifting from the template, and nothing guarantees the consistency of the whole.

Effective correction works through intent: "slides 4 to 7 are too detailed for this audience, condense them into two", "every finding must end with a recommendation", "replace all topic titles with assertions". An instruction of that kind propagates across the whole document and preserves consistency, where twelve manual edits destroy it.

The exit checklist

Before sending anything:

• The corporate template's theme is the one actually applied.
• Every title is an assertion, not a topic.
• Every figure is traceable to a source I can produce.
• Scope and as-of date appear on the data slides.
• I have deleted at least two slides. If I could not delete anything, I have not reviewed it.
• Footer and numbering are present on 100% of slides.

Where a tool is judged

A generator is not judged on the first version; every demo is convincing. It is judged on three things: does it start from your template, does it accept your raw material, and is the third iteration as clean as the first.

That is the line of work behind Paul: building on your corporate template rather than imposing an aesthetic, ingesting your sources as they are, and staying editable as PPTX on the way out. How it behaves on a real corporate template is described on the corporate template use case, and the terms of use on the pricing page.

That leaves the part that cannot be delegated: deciding what you want from the room. No amount of raw material substitutes for that sentence, and it is what keeps a deck from being generic.
