ChatGPT Prompt for Writing an Internal Memo
Writing an internal memo is a delicate exercise that requires clarity, conciseness, and a tone adapted to the company culture. Whether it's announcing a reorganization, a new partnership, or an HR policy update, the memo must convey essential information while maintaining employee engagement. ChatGPT becomes a valuable ally here: by providing it with context, target audience, and desired tone, you get a structured and professional first draft in seconds. The AI helps you overcome writer's block, find the right diplomatic wording, and ensure a logical structure (context, announcement, impact, next steps). Instead of starting from scratch, you iterate on a solid foundation, significantly reducing writing time while improving the quality of the final message. This prompt is designed to produce ready-to-send memos, adapted to the codes of French corporate communication.
The prompt
You are an expert in corporate internal communication. Write a professional internal memo following these parameters:
Subject of the announcement: [DESCRIBE_THE_SUBJECT — e.g., launch of a new telework program]
Target audience: [e.g., all employees / managers / sales team]
Desired tone: [e.g., formal and reassuring / enthusiastic / neutral and factual]
Sender: [e.g., Human Resources Department / CEO / Executive Committee]
Key information to include: [LIST_THE_ESSENTIAL_POINTS_TO_COMMUNICATE]
Effective date: [IF_APPLICABLE]
Structure the memo as follows:
- Subject line: a clear and direct line
- Introduction: briefly contextualize why this memo is sent
- Message body: develop the key information with short paragraphs
- Impact for employees: explain concretely what changes for them
- Next steps: expected actions or timeline
- Contact: person or department to contact for questions
Use professional French without unnecessary jargon. Sentences should be short and direct. Avoid excessive passive voice. The memo must fit on one page maximum.

Why it works
This prompt works thanks to the expert role assignment that anchors ChatGPT in the corporate communication register. The imposed six-section structure ensures that all essential elements of a memo are covered, while the contextual parameters (tone, audience, sender) allow fine personalization. The stylistic constraints (short sentences, no jargon, one page maximum) avoid the usual pitfalls of AI and produce directly usable text.

Claude Prompt to Create a Presentation
Creating a compelling presentation requires much more than lining up bullet points on slides. You need to structure a narrative, prioritize information, adapt the tone to the audience, and produce visually thoughtful content. Claude excels at this task because it can simultaneously act as a communication strategist, a copywriter, and a content designer. By providing it with a well-crafted prompt, you get a complete presentation with a coherent narrative structure, catchy titles, speaker notes, and visual suggestions. Whether you're preparing an investor pitch, internal training, a conference, or a simple team meeting, Claude adjusts the level of detail, vocabulary, and format to your context. The major advantage is time savings: instead of starting from a blank page, you begin with a solid foundation that you refine according to your needs. Claude can also generate content in various usable formats — structured Markdown, a detailed slide-by-slide plan, or even HTML code for tools like Reveal.js. This approach transforms presentation creation from a time-consuming chore into an assisted creative process where you focus on the message rather than formatting.
