Comment l’IA remplace 4 heures de PowerPoint (le hack dévoilé)

In this video, the speaker demonstrates how artificial intelligence is revolutionizing the way professional presentations are created. While many people struggle with last-minute preparation—often spending four or five hours on a single deck—AI can now reduce this workload to about thirty minutes. This efficiency is achieved through a two-step process involving content generation and automated graphic design, a method that can be applied to any industry or subject matter. The demonstration focuses on the real estate sector, a field where many professionals require high-quality, branded pitch decks to present investment opportunities. In the example provided, the goal is to create a professional presentation for a real estate project in Montpellier, in the South of France, within a very tight timeframe. The first step of the workflow utilizes a chatbot, specifically Google’s Gemini. The speaker uses a voice prompt to ask the AI to imagine a persuasive ten-slide pitch. The prompt requests specific details, including bullet points and indications for where to include diagrams or visuals. Gemini generates this complete content outline in just a few seconds, providing a structured brief that is ready for the next phase. The second step involves a tool called Jenspark, which handles the graphic production. By simply copying and pasting the content generated by Gemini into Jenspark’s "AI Slide" feature, the software automatically builds the visual presentation. The speaker highlights that the resulting slides are not only professional but also maintain a consistent premium aesthetic. In this instance, the AI chose a blue and gold color palette, which is typical for luxury real estate branding. The quality of the output is particularly impressive because the AI integrates relevant visuals—such as architecture that reflects the specific region of Southern France—alongside data-driven elements like dashboards and histograms. The speaker notes that users have the option to provide their own brand book, specific color codes, or fonts to ensure the final product perfectly matches their corporate identity. Finally, the speaker explains that this technology shifts the user’s role from a "laborious and boring" task to a creative and supervisory one. Once the slides are generated, they can be edited directly within the tool or exported to PowerPoint for manual adjustments. By combining personal expertise and specific data with these AI tools, professionals can produce high-quality results in a fraction of the time it previously required.
