If your ChatGPT answers feel mediocre, the problem is almost certainly your question, not the AI.
The most common pattern is also the most disappointing one: someone types “Write me an email to my boss” and gets back a stiff, generic, slightly creepy email that sounds like nothing they would ever send. They conclude AI isn’t very good. They go back to writing emails the hard way.
What actually happened is that the AI did exactly what was asked. It wrote an email to a boss. Without any of the things that make an email yours — who your boss is, what tone you use, what you’re actually trying to say, how short or long it should be, what the relationship is. Garbage in, garbage out.
This article is the simplest version of how to fix that.
Why most prompts fail
Most “bad” AI answers come from three predictable mistakes:
Fix those three things and your answers leap forward. There’s no magic syntax, no secret keyword, no “act as a Harvard professor” hack required. Just three categories of information.
The three things every good prompt needs
Think of the AI as the world’s most willing intern who has read every book ever written but knows nothing about you specifically. You need to brief them.
Context — who, what, why
Tell the AI the situation. Who you are, who the audience is, what you're trying to do, what's happened so far. "I'm a freelance designer. I'm writing to a client who hasn't paid an invoice that's now 30 days late. We've worked together for two years and the relationship is good — I want to be firm but not damage it."
Specifics — what kind of answer you want
Tell the AI what good looks like. Examples, constraints, things to include or avoid. "It should mention that I'd love to start the next project but need this one settled first. Don't mention legal action or late fees. Don't sound corporate."
Format — how you want it structured
Tell the AI the shape of the answer. Length, format, tone, structure. "Draft a 4-sentence email. Warm but direct. Casual but professional. End with a question that requires a response."
Stack those three and you go from “Write me an email to my client” (which gets you a generic placeholder) to a prompt that produces something close to what you’d actually send. The difference is dramatic.
The basic template
Steal this and adjust:
I’m [who you are]. I’m [what you’re doing] for [who the audience is]. The situation: [what’s happened, relevant context]. I want the result to: [what good looks like, things to include]. Avoid: [things to skip]. Format: [length, tone, structure]. Here’s what I have so far: [if any] / Here’s the relevant input: [paste anything you want it to work with].
Most of your prompts won’t need every field. But running through this list mentally before you hit send will catch the missing piece nine times out of ten.
10 templates you can copy
Each of these works for the named task. Replace the bracketed parts with your specifics.
1. Reply to a tricky email
Help me reply to this email. The sender is [relationship]. Their main ask seems to be [your read]. I want to: [agree / decline / negotiate / buy time]. Keep it under [N] words. Tone: [warm and casual / direct and professional / friendly but firm]. Don’t [things to avoid]. Email below: [paste]
2. Summarize a long document
Summarize this document for me. Audience: [who will read the summary]. Length: [N words / N bullet points]. Focus on: [what matters most for that audience]. Skip: [what doesn’t matter]. Document below: [paste]
3. Brainstorm options
I’m trying to [your goal]. The constraints are: [list them]. I’ve already considered [what you’ve thought of]. Give me [N] options I might not have thought of. For each, include: 1) the idea in one sentence, 2) why it might work, 3) the biggest risk.
4. Explain something complicated
Explain [topic] to me. I [your background — beginner / know X but not Y / total novice]. Use [analogies / examples from daily life / no jargon]. Length: [a paragraph / a page / as long as needed]. Start with the most important point.
5. Plan a project
I want to [the goal]. I have [time / budget / resources available]. The deadline is [when]. Constraints: [list]. Walk me through this in [N] steps, with rough time estimates for each step and what the risk is at each step.
6. Write to a difficult person
Help me write [a message / email / text] to [relationship + brief description]. I’m trying to [your real goal]. The history is [what’s happened]. I want to come across as [adjectives — calm, firm, etc.]. They tend to react badly to [what to avoid]. Keep it [length and format].
7. Practice for an interview / hard conversation
Pretend you’re [the person — interviewer, my boss, etc.]. The context is [background]. I’m going to ask you something — respond the way that person realistically would, including their actual concerns and pushback. Don’t go easy on me. Ready?
8. Improve something I wrote
Edit this for [purpose — clarity, brevity, professional tone, etc.]. Audience: [who will read it]. Things to keep: [voice, key points, jargon they expect]. Length goal: [N words or shorter than original]. Mark what you changed and why. Original below: [paste]
9. Decide between options
I’m trying to decide between [options]. My priorities are [list, ranked if you can]. Things I’m worried about with each: [list]. Walk me through the strongest case for each option, then give me your recommendation and why. Don’t try to be balanced — pick one.
10. Learn something step by step
Teach me [topic] in [N] short lessons. I [your background]. After each lesson, give me a quick check-for-understanding question. Don’t move to the next lesson until I’ve tried to answer. Start when I say “ready.”
The single-most-effective improvement
If you change exactly one thing about how you use AI, change this:
Some of the best AI users barely write long prompts at all — they write short ones and iterate fast. Both styles work. The key is the iteration.
Common mistakes that kill answers
Build your own template library
The most useful thing you can do over time is save prompts that worked. Keep a small text file or note titled “Prompts that worked.” When you find a phrasing that produces consistently good results — for emails, summaries, planning, whatever — save it. Within a few months you’ll have a personal library that’s worth more than any prompt course you could buy.
Where to start
Open ChatGPT or Claude right now. Pick something you’ve actually been meaning to do — write a difficult email, plan a trip, summarize a long article, decide between two options. Use template #1, #4, or #9 above. See what changes.
The whole article is shorter than the time it’ll take you to do that one thing — and at the end of it, you’ll know more about prompting than 90% of people who use AI.
