DALL-E Prompt to Create a Pitch Deck
DALL-E, OpenAI's image generator, is a powerful ally for designing visuals for a compelling pitch deck. Instead of spending hours on generic stock image banks or waiting for deliverables from a graphic designer, you can generate custom illustrations for each slide: impactful cover, conceptual infographics, visual metaphors for your market data, or product staging. The challenge is to formulate prompts that produce professional visuals, consistent with each other and aligned with your startup's visual identity. A good DALL-E prompt for a pitch deck should specify the desired graphic style, color palette, level of minimalism, and business context. Investors judge a deck in seconds: polished and original visuals reinforce your credibility and anchor your storytelling. In this guide, you'll find an optimized main prompt along with variants adapted to your level of expertise, to turn DALL-E into a real art director for your presentation.

Create a professional illustration for a startup pitch deck slide. Style: modern minimalist flat design, suitable for an investor presentation. Color palette: navy blue (#1B2A4A), white, and emerald green accents (#2ECC71). The image represents [SLIDE_TOPIC: e.g., market growth, product solution, founding team]. No text in the image. Airy composition with plenty of negative space to allow text overlay. Crisp, vector-like rendering, no photorealistic texture. 16:9 format, high quality resolution.

Why this prompt works
This prompt works because it imposes precise visual constraints (flat design, defined palette, 16:9 format) that guarantee consistency across all the deck's slides. The instruction to exclude text and preserve negative space anticipates the actual use in a presentation. The explicit mention of the 'investor' context directs DALL-E toward a professional rather than creative or fanciful register.
Use Cases
Variants
Expected Output
You get a clean illustration in flat design style, in navy blue and emerald green tones, perfectly sized in 16:9 for a presentation slide. The image is airy enough to overlay titles and figures, and the vector-like rendering gives it a professional look consistent with tech startup pitch deck standards.
Frequently Asked Questions
How can I maintain visual consistency across all slides in a pitch deck using DALL-E?
The key is to reuse the exact same style instructions, color palette, and format in every prompt. Create a “style prefix” that you copy at the start of each generation (e.g., “minimalist flat design, palette #1B2A4A / #F8F9FA / #2ECC71, 16:9 format, vector rendering”). Vary only the description of the specific subject for each slide. With DALL-E 3, you can also use the conversation mode in ChatGPT to explicitly ask it to maintain the same style as the previous image.
Which pitch deck slides are best suited for visuals generated by DALL-E?
The most suitable slides are: the cover slide (strong hook image), the Problem slide (visual metaphor of the pain point), the Solution slide (conceptual representation of the product), the Market slide (illustration of the opportunity), and the Vision slide (projection into the future). However, the Traction, Financials, and Team slides require real data (charts, team photos) and are less suited for pure AI generation.
What format and resolution should I choose for DALL-E images in a pitch deck?
Always request a 16:9 format (the standard for presentations) and the maximum available resolution. With DALL-E 3, select the 1792×1024 size, which matches the 16:9 ratio. If using the API, choose the 'hd' parameter for quality. Then export as PNG to preserve sharpness. If the image will serve as a slide background with text on top, make sure you requested enough negative space in your prompt.

ChatGPT Prompt to Compare Offers
Comparing commercial offers is a crucial step in any purchasing process, whether for a phone subscription, insurance, SaaS software, or service provider. Yet this task is often tedious: offers use different formats, highlight various criteria, and sometimes hide important conditions in the fine print. ChatGPT radically transforms this experience by becoming your personal comparative analyst. By providing it with details of several offers, it can structure them in a standardized table, identify key differences, calculate real costs over different periods, and highlight the pros and cons of each option according to your priority criteria. No more hours spent juggling browser tabs and Excel files: in seconds, you get a clear, reasoned summary that allows you to make an informed decision.
