I have been using ChatGPT for work for a while now. And the single biggest thing that separates useful AI output from generic AI output is not the tool — it is the prompt.
Most people type into ChatGPT the same way they type into Google. A few words, vague intent, hoping the AI figures out what they mean. And then they wonder why the output is mediocre.
After months of experimenting across real work situations — reports, emails, strategy decks, client prep — I have built a set of prompts that I actually use every week. Here are 20 of them, organized by the situations where they actually come up.
For Reports and Presentations
1. The Executive Summary Prompt
“You are a senior business analyst. Summarize the following data into a 5-bullet executive summary for a C-suite audience. Lead with the most important finding. Be direct. No filler. [paste your data]”
2. The Slide Title Prompt
“Convert these topic headings into declarative slide titles that state a conclusion, not just a subject. Instead of ‘Q1 Sales Performance,’ write ‘Q1 Sales Exceeded Target in 3 of 4 Markets.’ Here are my topics: [list]”
3. The Recommendation Prompt
“Based on this data, write a one-paragraph recommendation for leadership. Structure it as: situation, complication, recommendation. Be confident and specific. [paste data]”
For Emails
4. The Difficult Email Prompt
“I need to write an email declining a request without damaging the relationship. The situation: [describe]. Tone: professional but warm. Keep it under 150 words.”
5. The Follow-Up Prompt
“Write a follow-up email for a meeting where we discussed [topic]. Include: key decisions made, action items with owners, next steps. Tone: direct and efficient.”
6. The Cold Outreach Prompt
“Write a cold outreach email to [role] at [company type]. My value proposition: [1-2 sentences]. Goal: get a 15-minute call. No generic openers. Start with something specific.”
For Research and Analysis
7. The MECE Analysis Prompt
“Break down the following problem using MECE thinking — mutually exclusive, collectively exhaustive categories. Problem: [describe]. Give me the top 3-4 categories and what belongs in each.”
8. The Devil’s Advocate Prompt
“I am about to propose the following strategy to leadership: [describe]. What are the three strongest objections someone could raise? Be specific and realistic, not generic.”
9. The Market Summary Prompt
“Summarize what you know about [market/country] in terms of: market size, key players, growth trends, and main challenges. Structure it as a brief country brief for a sales manager.”
For Writing and Content
10. The Human Rewrite Prompt
“Rewrite this paragraph so it sounds like a person wrote it — not an AI. Remove any phrases that feel formal, robotic, or generic. Keep the meaning exactly the same. [paste text]”
11. The Clarity Prompt
“Read this and tell me: what is the main point? Is it clear in the first two sentences? If not, rewrite the opening so the key message comes first. [paste text]”
12. The Headline Prompt
“Write 5 alternative headlines for this article. Make each one specific, interesting, and under 10 words. Avoid clickbait. [paste article title or description]”
For Meetings and Planning
13. The Agenda Prompt
“Create a meeting agenda for a [type] meeting with [audience]. Goal of the meeting: [state clearly]. Time available: [X] minutes. Structure it to reach a clear decision by the end.”
14. The Pre-Meeting Prep Prompt
“I have a meeting tomorrow with [role/company] about [topic]. What are the 5 most likely questions or objections they might raise? Help me prepare a short answer for each.”
15. The Action Items Prompt
“Here are my rough notes from a meeting: [paste notes]. Extract: decisions made, action items with responsible person, open questions, and next meeting date if mentioned.”
For Strategy
16. The Options Prompt
“Give me three different strategic approaches to [problem]. For each: describe the approach, its main benefit, its main risk, and what conditions would make it the right choice.”
17. The One-Page Strategy Prompt
“Write a one-page strategy brief for [goal]. Structure: situation, objective, approach, key risks, success metrics. Keep each section to 2-3 sentences maximum.”
18. The Stress Test Prompt
“I am planning to [describe strategy]. Give me the three most likely reasons this fails. Be specific to this situation, not generic. Then suggest one mitigation for each.”
For Personal Productivity
19. The Priority Prompt
“Here is my task list for the week: [list]. Help me prioritize using the Eisenhower Matrix — urgent/important, not urgent/important, urgent/not important, not important/not urgent.”
20. The Learning Prompt
“Explain [concept] to me as if I understand business but not this specific topic. Use a real-world analogy. Then give me three practical ways I could apply this in a work context.”
The One Rule That Makes All of These Work
Every prompt above does the same thing: it gives the AI a role, a task, a format, and a constraint. That combination — role + task + format + constraint — is what separates a prompt that produces something useful from one that produces something generic.
Try one this week. If it does not work on the first attempt, push back. Ask for a different tone, a different structure, more specificity. The prompt is the beginning of a conversation, not a one-shot instruction.
That single mindset shift — from “query” to “conversation” — is what makes the difference between an AI tool that occasionally helps and one that becomes a genuine part of how you work.
