Stop typing to Google.
Start talking to a consultant.

Why AI misunderstands you — and why it's your fault

Think back to the last time AI gave you an answer that was... okay. Generic. Useful in the same way a Wikipedia article is useful — correct, but not helpful for your specific situation.

Why did that happen? Most likely because you asked the question the way you'd type a Google search.

To Google

To AI

The problem: AI is not a search engine. It's a conversation partner. And a conversation partner needs context to give you a good answer.

Think of it this way: you call a consultant who is an expert in everything. If you just say "ceo letter quarterly report template" — what do they respond? "Which industry? How did the quarter go? Who is reading this? What's the tone?" They ask for context. Not because they're difficult — because they want to give you a good answer. AI does the same thing, but silently. If you don't provide context — it assumes. And the assumptions are always generic.

The five elements of a prompt that always works

You don't need to remember all five every time. But the more you include, the better the answer.

  1. CONTEXT — Who are you? Tell AI who you are and what you do. "I'm the CEO of a 12-person consulting firm in Gothenburg." That's all it takes.
  2. TASK — What needs to be done? Be specific about the task. Not "help me with a letter" but "write a draft quarterly letter to our board."
  3. BACKGROUND — Why and what? Provide the relevant background. "We had a tough Q1 (-15% vs Q4 last year) but have a concrete plan for Q2."
  4. FORMAT — What should it look like? Specify length, tone, structure. "400 words max. Tone: direct but not panicked. No bullets — flowing prose."
  5. EXAMPLE — What should it sound like? If you have an example of the tone or style you want — paste it in.

The comparison that shows everything

Bad prompt
Write a CEO letter about Q1
Good prompt
I'm the CEO of a 12-person IT consulting firm in Gothenburg. We had a tough Q1 — revenue fell 15% vs Q4 last year, primarily because a large project was delayed to Q2. We have strong order intake and a realistic plan going forward.

Write a quarterly letter to our board (5 people, experienced business executives). The tone should be direct and accountable — acknowledge the challenge without sounding panicked. Focus on the Q2 plan. Max 400 words, flowing prose, no bullet points.

The difference in the answers? Night and day.

Exercise — 15 minutes

Choose a task you actually have on your plate today — an email you need to write, a document you need to summarize, a text you need to produce. Write a prompt with all five elements. Paste it into Claude. Compare with what you would have gotten if you had just written the task without context. Save both answers. You'll never go back.

Lesson 02 Open

The Power of Context — give AI the right background without writing a novel

Why "write an email" always fails

There's a common mistake even experienced AI users make: they ask AI to do the job without giving it the raw material.

"Write a follow-up email to a potential client."

Which email? Which client? What was the meeting about? What do you want them to do next? What's the tone of your relationship? AI writes something. It looks like an email. It's useless.

The key is to understand: AI is only as good as the information it has to work with. Garbage in, garbage out — just better written.

Three levels of context

Level 1 — Minimal
I run an accounting firm. A client is late on payment for the third month.
Level 2 — Standard
I run an accounting firm. The client Lars Andersson at Andersson & Co is late on payment for the third month — total debt 45,000 SEK. We want to keep the relationship but need to get paid. I've sent two previous reminders.
Level 3 — Full
...The email should be professional but firm. Not aggressive. Give him one last chance with a concrete deadline (10 days). Don't mention that we're considering debt collection — that's the next step if he doesn't respond. Max 150 words.

The technique: paste in raw material

One of the most powerful things you can do: give AI the actual raw material and let it work with it.

Instead of "Summarize the most important things from the meeting" — do this: "Here are my notes from the meeting: [paste notes]. Write a structured summary with: 1) Decisions, 2) Action items with owner, 3) Open questions. Max half an A4."

It takes 30 seconds to paste the notes. The result is ten times better.

The same principle applies to: email threads you need to reply to, contracts you need to understand, reports you need to summarize, articles you need to analyze.

Exercise

Find a task you used AI for previously and were unhappy with the result. Rewrite the prompt with full context. Run it. Note the difference.

Lesson 03 Open

Iterate, Iterate, Iterate — AI is a conversation, not an oracle

The most common mistake after getting an answer

You ask for something. You get an answer. It's 70% right. And you... accept it, or start over from scratch with a new prompt.

Wrong on both counts.

AI is designed for conversation. The best answer almost never comes on the first try — it emerges through dialogue.

Three ways to improve an answer

1 · Specific adjustments
Good foundation. Make the third paragraph shorter — it repeats itself. And the tone in the opening is too formal for our relationship with this client.
2 · Counter-example
This sounds too corporate. Here's an email I'm happy with: [paste it]. Rewrite with that tone.
3 · Follow-up questions
You mention three alternatives. Which do you recommend for a company in our situation and why?

Conversation memory is your superpower

AI remembers everything you've said in the conversation — until you start a new one. This means you can build up context iteratively without repeating yourself.

Example of an effective workflow:

  1. "I'm the CEO of X. We have problem Y. Help me think through it."
  2. AI reasons. You adjust: "What you're calling problem A isn't actually a problem — it's solved. Focus on B and C."
  3. AI adjusts. "Now give me a concrete action plan for B."
  4. "Good. Now write a draft email to the board based on what we've worked out."

Four messages. The result is tailored to your situation in a way that a single large prompt can never be.

When to start over vs. continue

Continue in the same conversation when: the answer is on the right track but needs adjustment, you want to build on what has been said, the tasks are related.

Start a new conversation when: the conversation has become long and sprawling (50+ messages), you're switching to a completely new topic, you want a "fresh" perspective without previous assumptions.

Exercise

Take an AI answer you got previously that was okay but not great. Write three iterations of follow-up prompts. Note how the answer changes. Most people find that answer number three is noticeably better than answer number one.

Lesson 04 Requires Email

System Prompts and Persona — build your personal AI assistant

One instruction you set once. AI that always knows who you are.

What is a system prompt?

A system prompt is the hidden instructions given to an AI model before the conversation begins. When you use Claude.ai, it's Anthropic's system prompt that controls how Claude behaves. But when you build with the API — or use Claude's Projects feature — you can set your own.

System prompt = AI's base identity for that session.

Why it matters for you

Imagine having a virtual assistant that always knows: who you are and what company you run, your communication style and tone, which topics it should be extra careful about, which format you prefer for answers.

Without a system prompt: you explain this in every conversation. With a system prompt: it's there from the start, every time.

Build your first system prompt

PART 1 — Your identity and context
You assist [YOUR NAME], founder of [YOUR COMPANY].
[Brief description of what you do and who you are.]
PART 2 — Communication preferences
Always respond in English unless otherwise specified.
Be direct and concrete — no unnecessary introductions or conclusions.
Avoid filler phrases like "That's a great question" or "Absolutely".
Format: flowing prose unless otherwise requested. Bullet points only when genuinely more appropriate than text.
PART 3 — Areas of expertise to prioritize
[YOUR NAME] is an expert in: [your areas of competence].
Treat them as a knowledgeable conversation partner — don't explain basic things they already know unless explicitly asked.
PART 4 — Specific instructions
If [YOUR NAME] asks for feedback on a text: be honest and specific about what isn't working.
If [YOUR NAME] asks for code: write production-ready code with comments.
If the question is unclear: ask ONE clarifying question, not several.

Where to put your system prompt

Claude Projects (easiest): Create a Project in Claude.ai, add the instructions to "Project instructions". Applies to all conversations in the project.

Claude API: Send the system prompt as a system field in your API request.

ChatGPT Custom Instructions: Settings → "Customize ChatGPT" → add the instructions there.

Exercise

Write your personal system prompt with the four parts above. Create a Project in Claude and add it. Start a conversation and compare with how Claude responds without the instructions.

Advanced Techniques — chain of thought, few-shot and role prompting

The tools that separate good AI users from truly great AI users

Chain of thought — force reasoning

Standard
What is the best price for our service?
With CoT
Think through pricing step by step: analyze our cost base, comparable market pricing, our positioning, and customers' willingness to pay. Then present a recommendation with justification.

Why it works: the model is forced to build up its reasoning step by step instead of jumping to a conclusion. The intermediate steps are visible — you can see where the reasoning might break down.

Key phrases that activate CoT: "Think through this step by step" · "Analyze each alternative before recommending" · "Show your reasoning" · "Go through pros and cons systematically"

Few-shot prompting — teach AI with examples

You want headlines in a specific style. Instead of describing the style — show it.

Few-shot
Write ten headlines in the style of these three:
- "What happens to your job? An honest analysis without hysteria"
- "AI is not a search tool — it's a thinking partner"
- "Stop using AI like Google"

Topic: AI and the future labor market.

The result matches the style. There's no magic — the model identifies the pattern in the examples and applies it.

Role prompting — give AI an expert identity

"You are an experienced CFO with 20 years of experience in growth companies."

Does it work? Yes — but not for magical reasons. The model activates patterns in training data associated with that role: CFO tone, CFO perspective, CFO priorities.

Use it for perspective, not for facts. An AI playing CFO gives you the CFO mindset — but can still have the wrong numbers.

Effective roles: "You are an experienced copywriter specializing in B2B SaaS" · "You are a senior lawyer focusing on contract law" · "You are a critical reader looking for weaknesses in arguments" · "You are a potential customer who is skeptical of the product"

Combine all five elements

The fully equipped prompt
[ROLE] You are an experienced business lawyer.

[CONTEXT] I run a 15-person tech company in Stockholm. We are about to enter a collaboration agreement with a German company for joint product development.

[TASK] Go through the following contract draft and identify the three most important risks for us as the Swedish party.

[FORMAT] Present each risk as: 1) What the risk is, 2) Where in the contract it is found (refer to the clause), 3) How serious it is, 4) Suggested solution.

[CHAIN OF THOUGHT] Analyze the contract systematically — read each clause and note potential problems before ranking the three most important.

[CONTRACT:]
[paste contract]

That prompt produces an answer a lawyer charges 5,000 SEK per hour to produce. You get it in 30 seconds.

Final Exercise

Choose a real, complex task you have right now. Write a prompt that uses a clear role, full context, specific task, desired format, chain of thought where relevant, and at least one example if you have one. Run it. That's how you work with AI from now on.
