This week we’re going to use AI for two very human, very common problems: **researching a major purchase** (without losing an entire weekend to tabs and YouTube) and **writing a professional decline email** (saying “no” without sounding rude or burning a bridge). These are the kinds of tasks that quietly drain your time and mental energy, especially if you like to be thorough and you care about how you come across.

Try at least one before Sunday. That is the whole assignment.

Use Case 1 of 2

Use Case 1: Researching a major purchase decision

On a Wednesday night, around 9:30 p.m., Angela is at her kitchen table with her laptop open and three pads of paper scattered around. She’s 57, works as a project manager, and her 12-year-old Honda has officially entered the “every repair is over $1,000” stage. Her mechanic has gently suggested it’s time.

Angela has spent the last four evenings bouncing between car review sites, YouTube videos, Reddit threads, and dealer pages. She has 18 tabs open. One review says a certain hybrid SUV is “bulletproof.” Another says the transmission is a nightmare. Some reviewers care about 0 - 60 speed; Angela cares about:

- Can I see over the hood? - Is it safe in the rain and snow? - Can I afford it without lying awake at 2 a.m.?

She’s exhausted, and she still doesn’t feel any closer to a clear decision. She doesn’t want AI to “pick a car for her.” She just wants someone to organize the chaos and talk to her like a smart adult with limited time and a real budget.

Here is the exact prompt to use:

Copy and paste this into ChatGPT or Claude:

Paste this into your AI tool and fill in the brackets with your details.

> I want help researching a major purchase. Act as a neutral research assistant, not a salesperson. > > Here’s my situation in plain language: > - I am [age], living in [city/state or country]. > - I am deciding whether to buy [brief description - e.g., “a new or used compact SUV,” “a mid-range laptop,” “a high-efficiency washer/dryer”]. > - My budget is roughly [budget range]. > - My top 5 priorities, in order, are: [e.g., safety, long-term reliability, total cost of ownership, ease of use, comfort]. > - Things I do NOT care much about: [e.g., sporty performance, having the latest model year, premium brand]. > > Step 1: Ask me up to 8 clarifying questions to better understand my needs, constraints, and preferences. Wait for my answers before moving on. > > Step 2: Based on my answers, map my situation onto 3 - 5 realistic options or strategies at a high level (for example: “buy a 3 - 5-year-old certified used model from X category,” “lease new,” “buy budget brand new,” etc.). Briefly explain the tradeoffs of each in plain language. > > Step 3: For the 2 most suitable options, create a side-by-side comparison focused ONLY on my stated priorities (not what car/gadget fans usually care about). Use simple headings, like: > - Upfront cost > - Likely 5-year cost (very rough estimate is fine) > - Reliability and maintenance patterns (in general, no promises) > - Comfort and everyday usability > - Any known “gotchas” or common complaints > > Step 4: Suggest 5 - 7 specific, practical questions I should ask a salesperson, technician, or knowledgeable friend to verify this research in the real world. > > Very important: > - If you are unsure about something, say so and suggest what I should check in the real world. > - Do NOT just repeat marketing language. > - Keep your tone factual and calm, like a trusted friend who has done a lot of homework.

Why this prompt works:

You are not asking, “What car should I buy?” You’re asking it to **play the role of a research assistant**, and you’re giving it a clear, 4-step job. The prompt forces the AI to *ask clarifying questions first*, instead of jumping to an answer. You also give it your priorities in order, which makes the comparison table meaningful instead of generic. Finally, you explicitly forbid sales-y language and encourage it to admit uncertainty, which improves the quality of the advice.

AI can’t see your local market, your exact dealer inventory, or your individual financial situation. It also sometimes sounds more confident than it should about reliability or prices. Always treat the output as a **first-pass map**, not the final word. Use the questions it suggests when you talk to real people (mechanics, sales reps, friends who own the product) and verify any numbers like prices, financing terms, and warranties directly.

Use Case 2: Writing a professional decline email

On a Monday afternoon at 3:15 p.m., Daniel is staring at an email he’s been avoiding all day. He’s 49, runs a small consulting practice, and a former colleague has invited him to join a nonprofit board. It’s a good cause. The colleague is someone he respects. But Daniel knows that if he says yes, he’ll be giving up the little bit of margin he has for his health and his family.

He’s already over-committed, and his doctor has used the phrase “you can’t outrun your calendar forever.” Still, the idea of writing, “No, I can’t do this,” makes his stomach clench. He doesn’t want to sound ungrateful, or as if he’s rejecting the person, not the opportunity. At the same time, he doesn’t want a three-paragraph life story about burnout. He needs something clear, kind, and firm.

He’s heard that AI can help with “writing emails,” but the last time he tried, it gave him a stiff, vaguely corporate paragraph that didn’t sound like his voice at all. This time, he wants to use AI more intentionally: not to decide *whether* to say no, but to help him say no in a way that reflects his actual values and tone.

Here is the exact prompt to use:

Copy and paste this into ChatGPT or Claude:

Again, paste this in and fill in the brackets.

> I need help writing a professional decline email that sounds like me. > > Context: > - I am [role/profession, e.g., “a freelance designer,” “a senior manager in healthcare,” “a self-employed consultant”]. > - The person I’m replying to is [relationship, e.g., “a former colleague,” “a long-time client,” “a friend from my professional network”]. > - They have asked me to [brief description: “join their nonprofit board,” “take on an urgent project,” “speak at an event,” etc.]. > - My real reason for saying no is: [be honest but brief; e.g., “I’m at capacity and protecting time for health/family,” “the work is outside my focus area,” “this conflicts with my role”]. I do NOT want to share the full details of this reason, just a simple, respectful version. > - My general tone: [choose 2 - 3 words like “warm,” “straightforward,” “formal,” “friendly but professional”]. > > Step 1: Ask me 5 - 7 short questions to understand: > - How long I’ve known this person > - How likely it is I will work with them in the future > - Whether I want to leave the door open for something else later > - Any specific phrases I definitely do or do not want to use > > Wait for my answers. > > Step 2: Draft 2 versions of the decline email: > - Version A: very concise (4 - 6 sentences) > - Version B: a bit warmer/more detailed (6 - 10 sentences) > > Both versions should: > - Start with appreciation for the invitation or opportunity, without overpromising > - Clearly, kindly say no, without vague language like “maybe later” unless I explicitly say that’s what I want > - Give a brief, honest but professional reason (e.g., “I’m at capacity with existing commitments”) > - If appropriate, suggest ONE alternative (another person, a later time, or a different way I can support) > > Step 3: After you show me both versions, give me a short checklist (5 - 7 bullet points) of things I can tweak to make the email sound even more like me (for example: change greeting, adjust level of formality, shorten certain phrases). > > Important: > - Keep the language natural and human. No exaggerated buzzwords or “thrilled/humbled/honored” unless I ask. > - Do NOT invent details about my schedule or personal life. Keep it simple and respectful.

Why this prompt works:

You’re giving the AI **your role, relationship, true reason, and desired tone**, so it has enough context to write something that fits your situation. You’re also forcing it to ask questions first, which pulls your own preferences into the mix. Asking for **two versions** gives you a choice without you having to rewrite from scratch. The checklist at the end reminds you that this is a draft to customize, not a script you must follow word-for-word.

AI tends to default to slightly formal, generic language. If you just copy and paste the first draft, it may sound a bit like a corporate memo rather than you. Before you send, read the email out loud; if a phrase makes you think, “I would never say it that way,” change it. Also be careful that the AI doesn’t accidentally imply future commitment (“next time,” “later this year”) unless you truly mean it.
