ChatGPT Prompt for Writing a Speech

Writing a compelling speech is a demanding exercise that requires a solid argumentative structure, a tone adapted to the audience, and the ability to captivate attention from start to finish.

The AI helps you organize your ideas, find the right phrasing, and build a narrative progression that will leave an impression.

The prompt we offer here has been designed to maximize ChatGPT's text generation capabilities by incorporating proven rhetorical techniques: strong hook, smooth transitions, emotional appeal, and memorable conclusion. You will save considerable time while producing a professional-quality speech that you can then personalize with your anecdotes and personal style.

Sora Prompt for Creating Flashcards

Sora, OpenAI's video generation model, opens up fascinating possibilities for creating visual and animated flashcards. Unlike traditional static flashcards, video flashcards generated by Sora capture attention through smooth transitions, dynamic illustrations, and memorable visual scenes. Whether you are learning a foreign language, reviewing scientific concepts, or memorizing technical vocabulary, Sora transforms each card into a short visual sequence that anchors information in your memory through dual coding (visual + textual). The main challenge is to formulate a precise enough prompt to obtain a consistent, readable, and educational format — with a clearly distinct front and back, visible typography, and a uniform visual style across the entire card deck. In this guide, you will find an optimized main prompt, variations adapted to your level, and practical tips for fully leveraging Sora in your spaced repetition learning process.

Perplexity Prompt for Creating a Software Architecture

Perplexity stands out as a particularly powerful tool for software architecture design thanks to its ability to synthesize recent and verified technical sources. Unlike a classic LLM that relies solely on its training data, Perplexity queries the web in real time to integrate the latest best practices, emerging architectural patterns, and community feedback. Whether you are designing a microservices architecture, a modular monolith, or an event-driven system, a well-structured prompt allows you to obtain contextualized recommendations with verifiable sources. The challenge is to provide enough business and technical context for Perplexity to cross-reference relevant information: technology stack, scalability constraints, infrastructure budget, and team skills. By phrasing your request precisely, you transform Perplexity into a true consultant architect capable of proposing component diagrams, reasoned technology choices, and deployment strategies tailored to your specific context.

Stable Diffusion Prompt for Creating a Business Plan

Stable Diffusion is an AI image generation tool that can transform your business plan presentation into a visually impactful document.

Stable Diffusion allows you to produce these visuals without hiring a graphic designer, in just a few minutes and at a lower cost. In this guide, we offer optimized prompts to generate the key illustrations for your business plan: from the visual representation of your value proposition to mockups of your product or service, along with ambient visuals that embody your market positioning.

This approach doesn't replace detailed design work, but it radically transforms the ideation and visual exploration phase. Product teams now use Midjourney to present creative directions to their clients, quickly explore multiple creative avenues, and establish ultra-realistic moodboards. Mastering prompt engineering for UI design with Midjourney means saving hours of work while significantly expanding your creative scope.

Claude Prompt for Creating E2E Tests

End-to-end (E2E) tests are essential to ensure your application works correctly from the end user's perspective. However, writing them is often time-consuming and repetitive: simulating complete user journeys, handling selectors, async waits, and UI state assertions. Claude excels at this task by generating structured, maintainable E2E tests covering both happy paths and edge cases. By providing context about your application — tech stack, test framework, page structure — Claude produces ready-to-run test suites for Playwright, Cypress, or other tools. It understands best practices like data-testid usage, the Page Object Model pattern, and loading state management. Whether starting from scratch or supplementing existing coverage, Claude transforms a functional description into robust tests in seconds, letting you focus on business logic rather than technical plumbing.

GitHub Copilot Prompt to Write a Cover Letter

GitHub Copilot, primarily known as a development assistant, also proves to be a formidable tool for writing professional documents like cover letters. Thanks to its ability to understand context and generate structured text, Copilot can help you produce a compelling letter in minutes. Whether you are applying for a technical position or not, the AI guides you in articulating your skills, background, and motivation convincingly. Copilot's advantage lies in its fine understanding of textual structures: it knows how to organize an argument, adapt the tone to the target industry, and highlight the key elements of your application. By providing a well-constructed prompt with relevant information—target position, company, skills, experiences—you get a personalized letter that far exceeds generic templates. This approach saves you considerable time while maintaining a professional quality level, allowing you to focus on final personalization rather than writing from scratch.

Whether you need to illustrate turnover trends, visualize workforce distribution, or design visual dashboards for an executive committee presentation, DALL-E transforms your raw data into compelling images. The tool particularly excels at creating visual metaphors that give meaning to numbers: a funnel for recruitment, a stylized age pyramid, or skills mapping. By combining precise instructions on the type of data to represent with graphic style directives, you obtain professional visuals that surpass the limitations of traditional data visualization tools. This approach is especially useful for strategic presentations, annual HR reports, and internal communications where visual impact takes precedence over numerical precision.

ChatGPT Prompt for Writing a Business Proposal

Writing a compelling business proposal is a demanding exercise that mobilizes both writing skills, in-depth client knowledge, and strategic structuring of the offer.

Sora Prompt for Survey Analysis

Survey analysis is a major challenge for marketing, HR, and research professionals. With hundreds or even thousands of responses to process, extracting relevant insights manually is time-consuming and prone to interpretation bias. Sora transforms this complex task into a structured, fast process. By feeding it your raw survey data, the AI identifies statistical trends, detects correlations between variables, and synthesizes open-ended responses into actionable themes. Whether you are analyzing a customer satisfaction survey, an internal employee engagement survey, or a market study, Sora helps you move from raw data to strategic decisions.

Conversion rate optimization (CRO) is a major strategic lever for any online business. Every percentage point gained on your conversion rate can mean thousands of euros of additional revenue, without increasing your acquisition budget. Claude excels at analyzing user journeys, identifying friction points, and formulating actionable recommendations. Unlike a purely analytical data-driven approach, Claude can combine behavioral analysis with principles of cognitive psychology, persuasive copywriting, and UX design to produce a comprehensive audit and prioritized A/B test hypotheses. Whether you're looking to improve the conversion rate of a landing page, a sales funnel, an e-commerce product page, or a signup form, Claude structures its analysis around proven frameworks such as WiderFunnel's LIFT model or Cialdini's heuristics. The result: a concrete action plan, prioritized by potential impact and ease of implementation, that your team can execute immediately.
