The No. 1 mistake for businesses that rely entirely on AI for their PowerPoint presentations

It is no longer a surprise, artificial intelligence is everywhere.

She writes, illustrates, designs... and now, it generates PowerPoints in a few clicks.

Tools like Tome, Gamma, or SlideSAI promise to turn any text into a ready-to-use presentation.

But while many are getting started, the big groups are going backwards. After several data leaks, Samsung has banned the use of ChatGPT. JPMorgan and Apple did the same, preferring to limit access to mainstream AIs to protect their internal information.

At Mprez, matthews, our AI expert, is following these developments closely. Its role: to understand how take advantage of AI without losing control of the message

And that is precisely the heart of the matter: can we really entrust all your PowerPoint presentations to an AI without losing impact, consistency and security?

Why businesses are being seduced by AI to do their PowerPoints

The promise: speed, automation, simplicity

For the past two years, the tools ofAI to make PowerPoint are multiplying at high speed.

Tome, Gamma, SlidesAI, Beautiful.ai or even PowerPoint Copilot : all promise the same thing, namely to transform an idea into slides in a few seconds.

The user only has to provide a text or a plan, and the AI takes care of the rest: structure, visuals, layout, tone of speech...

According to a study SketchBubble (2024), 82% of business leaders used an AI tool to create visual content (images, slides, videos) in 2024.

And no wonder these platforms are attractive: they allow To save time, simplify production and automate redundant tasks.

When it works: good use cases

THEAI who makes PowerPoints is not just a tech gimmick.

In daily tasks, she becomes a real work assistant.

For a team meeting, training or brainstorming, it helps to quickly structure ideas and create clean support effortlessly.

“Where there is no no strategic challenge, AI is a valuable aid. It allows you to go quickly, to test ideas, to release a clean medium without spending hours on it.”, Matthieu confirms to us.

These tools break the blank page syndrome and standardize the supports, which streamlines internal communication. But as soon as the objective is to convince, inspire or represent the brand, the limits appear.

Matthieu highlights this:”This is where the real mistake many businesses make: thinking that AI can do everything by itself.”

The mistake: believing that AI to make PowerPoint can replace human expertise

Correct presentations... but interchangeable

The promises of effectiveness ofAI to make PowerPoint seductive, until you look at the content closely.

Behind well-aligned slides, we often discover texts that are flat, agreed and without relief. In other words: clean, but interchangeable presentations.

According to HubSpot (2024), 86% of marketers reworking Systematically use AI-generated content to improve marketing tone or relevance.

Matthieu also reacts to this observation.”AIs write as if everyone is talking about the same thing. The sentences are correct, but rarely compelling.”

Finally, AI structures, but does not nuance: it ignores the context, the subtleties of speech, the right tone.

When logic replaces storytelling

You've noticed, AI tools line up bullets and titles, but struggle to build a true story. Their approach remains “mechanical”: they use a logic without emotion or strategic intention.

Result: content without storytelling, which does not explain wherefore The message counts, neither For whom it is built.

”An AI can summarize your ideas, but it can't make sense of them. ”, Rephrase Matthieu for us.

And the audience feels that. Indeed, according to a Bynder survey (2024), 52% of consumers disengage from content that they think was designed by an AI.

Standardized designs, diluted brands

While the AI for PowerPoint promises to generate harmonious visuals, the result often ends in to be similar from one brand to another.

The models offered by tools like Gamma, Beautiful.ai or Tome are certainly aesthetic, but their visual signature remains immediately identifiable. According to a survey by Baringa (2025), 81% of consumers consider that content created by humans is more authentic and original than the one produced by an AI.

These “pre-trained” models seek to please everyone... and end up To look like everyone.

Matthieu often observes this with his customers:”AI can replicate a style, not create one. It is still unable to create documents that are really linked to a customer's graphic identity. A human will know how to place the colors, the logo, the photos and use the visual codes specific to each brand (illustrations, patterns, patterns, etc.).”

The problem is not limited to aesthetics: it relates directly to brand identity.

A “correct” medium but without personality gives an impression of amateurism. During a commercial pitch, Of a Fundraising Or of a strategic committee, this can be very significant, since 88% of consumers say that authenticity is important when they decide which brands they love and support (Stackla, 2021).

Result: one “custom-made fake”, as Matthieu calls it, which undermines coherence and credibility.

And data in all of this?

Matthieu reminds us: “An AI does not differentiate between an innocuous text and a confidential document.”

And big companies got it: Samsung, JPMorgan or Apple have banned the use of tools like ChatGPT internally, after several sensitive data leaks.

And this trend is continuing.: according to BlackBerry/OnePoll (2023), 82% of French businesses are considering banning the use of ChatGPT internally for this reason.

La data security and control are therefore becoming an issue as crucial as the design or the message.

Why human expertise makes a difference

Strategic storytelling: when content precedes form

One AI PowerPoint can align ideas, but it can't Tell a story.

And a successful presentation is above all A story : why this message matters, for whom, and how it is articulated.

According to Matt Abrahams (Stanford), information told in the form of narration is retained 40% more effectively.

That's why big brands work with expert PowerPoint agencies, capable of transforming a series of data into a discourse of conviction.

Custom design: coherence and impact

One well-aligned template is not enough to embody a brand.

Design is a strategic language: it expresses tone, personality, and credibility of a company.

Chez Mprez, our designers and storytellers work closely together to create materials legible, aesthetics and memorable.

Matthieu points it out: “Good design is not the one that impresses, it is the one that guides. It helps the audience effortlessly understand what you mean.” It complements: “A beautiful PowerPoint is a document that integrates all brand codes to remain consistent with the company's image. And it is even more important to have well-written documents, where the visual identity is highlighted, for strategic supports such as a commercial pitch or a fundraiser.”

Control and confidentiality

Human expertise guarantees the reliability and consistency of the message.

An AI can generate content that looks perfect, but Wrong in substance.

At mprez, each presentation is checked twice, editorially and visually, to ensure the accuracy and rigor of the content.

Moreover, Matthieu sees this as a wider issue than simple verification: “Human control is not just about proofreading, it's about maintaining control of the message. In a large company, each word, each number, each slide engages the brand. No AI can take on this level of responsibility.”

And unlike mainstream AI tools, professional PowerPoint agencies work Under NDA, in an environment secure and confidential.

Finding the right balance: combining PowerPoint AI and human expertise

AI PPT, an asset for speed and simplicity

THEAI to make PowerPoint is a real lever for efficiency.

For internal presentations, meetings, reports, training courses, it allows you to get straight to the point: transform raw content into clear and legible slides.

” AI, when used to automate redundant tasks (alignments, visual coherence, color palettes) or the creation of low added value media (internal presentations, brainstorming support, etc.), makes it possible to free up time on the content and to fully use all its advantages without its drawbacks. ”, explains Matthieu.

In these uses, speed takes precedence over differentiation: a Free PowerPoint AI is often enough to save time, and that is the desired effect.

Human expertise, guarantor of coherence and impact

As soon as a presentation goes beyond the internal framework, the priority changes: you must convince, inspire, represent the brand.

” The AI lines up slides. Humans develop a vision. And that's what your audience feels and retains ”, insists Matthieu.

Human expertise provides storytelling, graphic coherence, and strategic intent that the machine cannot understand.

According to the MIT (Ju & Aral, 2025), the teams that combine AI and human know-how are nearly 60% more productive than those that are entirely human, while maintaining, or even improving, the quality of text content. ” AI executes an idea, concludes Matthieu, but only humans give it meaning and coherence.” concludes Matthieu.

THEAI for PowerPoint seduced by its speed, simplicity and accessibility.

For internal presentations, it's a undeniable time saver that lightens the daily life of teams.

But when it comes to convincing, embodying a vision or defending a strategic project, its limits become obvious : generic slides, absent storytelling, and emotionless messages.

Conversely, use a expert agency like Mprezis choosing coherence, meaning and differentiation. You gain turnkey support, designed to inspire, engage and convince, without spending hours correcting or harmonizing your slides.

So the real question is no longer “Should you use an AI for your PowerPoints?” but rather: What impact do you expect from your presentations?
