Prompt examples

Writing — First draft opener

Act as a [role, e.g. feature journalist / content strategist / technical writer]. Write the opening 150 words of a [format] about [topic] for [audience]. The goal is [desired outcome — e.g. to make them want to read further / to establish credibility / to address a common misconception]. Tone: [tone]. Do not use filler openers like 'In today's world.'

Works across all writing tasks. The role + audience + goal combination is the most reliable structure for writing prompts.

Business — Decision analysis

Act as a business strategy advisor. I need to decide between [option A] and [option B]. Context: [describe your situation, constraints, and what matters most]. For each option, analyze: main benefit, main risk, resource requirement, and reversibility. Then give a recommendation based on [my top priority]. Keep it to one page.

Add specific numbers or timelines when you have them — specificity dramatically improves the usefulness of AI decision analysis.

Marketing — Campaign concept

Act as a creative director. We are launching [product/offer] targeting [audience]. The audience's core tension is [describe what they want vs. what is holding them back]. Give me 3 campaign concept directions — each with a concept name, one-sentence idea, a sample headline, and the primary emotion it drives. Make the three concepts meaningfully different from each other.

Give AI the audience tension, not just the product. The insight behind a campaign is more important than the product description.

SEO — Content brief

Act as an SEO content strategist. Write a content brief for the keyword [keyword]. Include: search intent (informational / commercial / transactional), suggested H2 headings with one-sentence descriptions, FAQ questions likely to appear in PAA boxes, word count guidance, and one differentiation angle that the current top-10 results do not cover.

Always analyze the SERP manually before using AI for briefs. AI does not know what is currently ranking.

Coding — Debug and explain

I have a bug in this [language] code. The code is supposed to [describe intended behavior]. What is actually happening: [describe the bug]. Here is the code: [paste code]. Please: 1) identify the root cause, 2) explain it in plain language, 3) provide the corrected code with the change highlighted in a comment.

Add the error message if you have one — it dramatically narrows the diagnosis.

Research — Structured summary

Act as a research analyst. Summarize the following [source type — article / paper / report / transcript] on the topic of [topic]. Output format: 1) main argument or finding (2 sentences), 2) 3 key supporting points, 3) one significant limitation or caveat, 4) implications for [my field / business / decision]. Here is the source: [paste or describe source].

Specifying the output format as a numbered list prevents AI from writing a rambling prose summary.

Email — Persuasive outreach

Act as a [role, e.g. partnerships manager / sales rep / PR specialist]. Write a cold outreach email to [target role] at [target company type]. Goal: [specific ask — a 20-min call / a partnership discussion / a guest post]. Our value to them: [describe one specific benefit to them, not to you]. Length: under 120 words. No 'I hope this email finds you well.' End with a low-friction ask.

The key mistake in outreach prompts is describing your value to yourself rather than their gain. Flip it.

Creative — Character voice

Act as a creative writing coach. Write a 200-word scene from the perspective of [character description] in the moment of [specific situation or decision]. The character's internal tension is [describe]. Do not explain the tension — show it through action, dialogue, and sensory detail. Tone: [literary / genre / accessible].

The more specific the situation and internal tension, the more interesting the output. Avoid generic emotional states.

Presentation — Executive summary

Act as a business communication specialist. Summarize this [report / strategy / proposal] into a 5-bullet executive summary readable in 60 seconds. Each bullet should be a standalone insight — not a heading. Lead with the most important finding. Include one clear recommendation and one risk to flag. Here is the source material: [paste].

Useful for compressing long documents before presenting to leadership or clients who will not read the full version.

Education — Concept explanation

Act as an expert teacher for [audience level — beginners / professionals / 5th graders]. Explain [concept] using an analogy the audience will immediately recognize. Then give one real-world example of [concept] in action. Then give two common misconceptions and correct them. Keep the total explanation under 300 words.

Specifying an analogy forces the AI to connect the concept to something concrete instead of explaining it in abstract terms.

Common mistakes to avoid

Vague tasks: "Write something about marketing" gives AI no direction. Be specific about the format, audience, goal, and constraints.
No role assignment: Adding "Act as a [specific role]" consistently improves output quality because it sets the expertise frame for the response.
Accepting first output: The best prompts are iterative. After the first response, follow up with: "make the opening stronger," "shorten this by 30%," or "give me two more approaches."
Ignoring format instructions: If you need a table, a list, or a specific structure, say so explicitly. AI defaults to prose unless instructed otherwise.

How to customize these prompts

Every prompt in this collection has bracket fields — replace them with your specific role, audience, topic, tone, and goal. The more precise your inputs, the more useful the output. Think of these as templates with intentional blanks, not ready-to-run commands.
