We still spend far too much time typing vague requests into ChatGPT, then starting again because « it doesn’t give me what I want« . Conversely, a good, clear and structured prompt turns the AI into a reliable work tool, almost a specialized colleague. Rather than piling on « AI tips, » here’s a minimalist toolbox: four ready-to-use prompts you can almost copy and paste. Each one corresponds to a concrete everyday use case: learning, selling, testing a business idea and writing professional emails. These prompts are not set recipes, but rather the basics. It’s up to you to adapt them to your business, your sector and your language!

Turning a technical manual into a personal coach

The prompt
« I’m going to upload a screenshot of a manual page. Read it to me word for word, then explain the technical parts in a simple, easy-to-understand way. Then ask me three multiple-choice questions (one at a time) based on the text. After answering the questions, ask me for the next upload. »

What this prompt does, in practice: This prompt combines several functions: it reads the text to let you concentrate on the meaning, simplifies technical passages by rephrasing them clearly, and reinforces comprehension thanks to MCQs that turn reading into active checking. It’s a real « process » prompt, establishing a method that the AI applies repeatedly rather than a one-off answer[/frame]

From business idea to crash test

[frame template= »normal »]

Prompt:

« I need to evaluate this business idea: [BUSINESS CONCEPT]. Please provide a comprehensive analysis that :
Tests the key assumptions on which the business model is based.
Identifies overlooked market factors that could impact success.
Proposes 3 alternative business models that better exploit the core value of the offering.
Assesses competitive threats beyond obvious direct competitors.
Suggests unexpected customer segments worth exploring.
Recommends clear metrics to validate or invalidate key hypotheses.
Identifies pivot opportunities if initial assumptions prove incorrect.

Focus on challenging conventional thinking rather than the standard elements of a business plan. »

What this prompt does, in practice

This prompt pushes AI to challenge your business idea instead of automatically validating it. It analyzes assumptions, highlights blind spots, explores alternative business models and proposes metrics to check the viability of the project. You get a true strategic stress-test, useful before launching anything.[/frame]
