Writing with AI: the most practical superpower
Writing well is one of the most valued skills at work, and AI does it fast and effortlessly. But there is a secret that changes everything: the result depends on the prompt you give it.
In this second course module you will learn to write prompts that work, see bad vs good examples and take away copy-paste ready templates.
The perfect prompt formula
A solid prompt has five ingredients. You do not always need all of them, but the more the better:
- Role: who you want the AI to be ("act as a communications manager").
- Context: the information it needs to understand the task.
- Task: what you want exactly ("draft an email...").
- Tone: formal, friendly, convincing, brief...
- Format: email, list, table, summary...
Examples: bad vs good
Changing a few words completely transforms the response. Look at this:
| Bad prompt | Good prompt |
|---|---|
| "Write an email" | "You are the marketing manager of an online store (role). Write an email (task) to a customer complaining about a late order (context), in a friendly tone apologizing (tone), max 6 lines (format)." |
| "Summarize this" | "Act as a financial analyst. Summarize this report (context) into 5 key points with the most important figures (format)." |
| "Give me ideas" | "I run a small business with no marketing budget. Give me 8 concrete ideas to win local customers in 2026, each explained in two sentences." |
The second column always wins. The more context, the better the result.
Copy-paste prompt templates
Save these templates and adapt them. Save yourself inventing prompts every time:
| Type | Template |
|---|---|
| Professional email | "Act as [role]. Write an email to [recipient] (task) because [context]. Tone [tone], max [X] lines." |
| Report | "Summarize this [text] into a report (task) with executive summary, key points and recommendations sections (format). Formal tone." |
| Sales message | "Write a [channel] message to a customer who [context]. Lead them to respond with the hook [X]. Tone convincing but not aggressive." |
| Proofreading | "Review this text and correct it: improve clarity, remove repetitions (task) and tell me what you changed (format)." |
How to review and edit what it generates
AI only delivers a draft. Your editing job is what gives it the final touch:
- Read it aloud to catch sentences that sound artificial.
- Shorten redundant paragraphs: AI tends to over-elaborate.
- Personalize with real data and details the AI does not know.
- Verify figures and dates before sending.
- Ask for iterations: "make it shorter", "more friendly", "different tone".
With this cycle (generate → edit → adjust) you will get professional-quality text in minutes.
Conclusion
Writing better with AI is not magic: it is giving clear instructions and editing the result. Master the prompt formula, use templates and never send the text without your review.

Author's opinion
The difference between a good and a bad AI response is almost always the quality of the prompt. I have seen people get frustrated with the tool when the real problem was that they were asking vague things. Once they understood that giving role, context and tone was enough, their productivity skyrocketed.
My advice: keep a document with the prompts that work and reuse them. You do not need to be clever, just clear. And remember that AI delivers an excellent draft, not a final text. Your editing judgment is what separates a mediocre email from a brilliant one.

Frequently asked questions
How do I write a good prompt?
Use the formula role + context + task + tone + format. The clearer and more contextual your request, the better the result. Provide examples if you can.
Can I use AI to write professional emails?
Yes, it is one of its most powerful uses. Ask it to draft the email, review it, adapt it to your tone and fix anything that sounds odd. It helps a lot, but always review.
Does AI write better than me?
It is faster and rarely gets stuck, but it lacks your judgment and voice. The ideal is to use it as a first draft and you bring the human touch and final review.
How do I avoid it sounding like AI?
Give real context, ask for a specific tone, shorten and rewrite sentences, and add details from your own experience. The more personal and direct, the less it 'sounds like AI'.
