Stop writing 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 entry is useful — correct, but not helpful for your specific situation.

Why did that happen? Most likely because you phrased the question as if you were doing a Google search.

To Google

To AI
vd-letter quarterly report template

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

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

The five elements of a prompt that always work

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 them who you are and what you do. "I am the CEO of a consulting firm with 12 employees in Gothenburg." That is all that's needed.
  2. TASK — What needs to be done? Be specific about the task. Not "help me with a letter" but "write a draft of a quarterly letter to our board."
  3. BACKGROUND — Why and what? Give it the relevant background. "We had a tough Q1 (-15% compared to Q4 last year) but have a concrete plan for Q2."
  4. FORMAT — What should it look like? Specify length, tone, structure. "Max 400 words. Tone: direct but not panicked. No bullet points — running text."
  5. EXAMPLE — How should it sound? 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 am the CEO of a 12-person IT consulting firm in Gothenburg. We had a tough Q1 — revenue fell by 15% compared to Q4 last year, primarily because a large project was delayed until Q2. We have a strong pipeline and a realistic plan moving forward.

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

The difference in the responses? 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 it with what you would have received if you had only written the task without context. Save both responses. You will 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 is a common mistake that even experienced AI users make: they ask the AI to do the job without providing the raw material.

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

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

The key is to understand: AI is only as good as the information it has to work with. Garbage in, garbage out — just more well-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 in a row — total debt 45,000 SEK. We want to maintain the relationship but must get paid. I have 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). Do not mention that we are considering debt collection — that is the next step if he doesn't respond. Max 150 words.

The technique: Paste the raw material

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

Instead of "Summarize the main points from the meeting" — do: "Here are my notes from the meeting: [paste notes]. Write a structured summary including: 1) Decisions, 2) Action items with responsible parties, 3) Open questions. Max half an A4 page."

It takes you 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 have used AI for before and were dissatisfied 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 receiving an answer

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

Wrong in both cases.

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's repetitive. And the tone in the introduction is too formal for our relationship with this customer.
2 · Counterexamples
This sounds too corporate. Here is an email I am happy with: [klistra in]. Rewrite it using that tone.
3 · Follow-up questions
You mention three options. Which one 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 flow:

  1. "I am the CEO of X. We have problem Y. Help me think through it."
  2. AI reasons. You adjust: "What you call problem A is actually not 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 come up with."

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 was said, the tasks are related.

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

Exercise

Take an AI response you received earlier that was okay but not great. Write three iterations of follow-up prompts. Note how the answer changes. Most notice that response number three is noticeably better than response number one.

Lesson 04 Requires email

System prompts and persona — build your personal AI assistant

One instruction you set once. The 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 is Anthropic's system prompt that governs how Claude behaves. But when you build with the API — or use Claude's Projects feature — you can set your own.

System prompt = the AI's core identity for that session.

Why it matters for you

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

Without a system prompt: you have to tell it 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 are assisting [DITT NAMN], founder of [DITT BOLAG].
[Brief description of what you do and who you are.]
PART 2 — Communication preferences
Always respond in Swedish unless otherwise specified.
Be direct and concrete — no unnecessary introductions or conclusions.
Avoid clichés like "That's a great question" or "Absolutely".
Format: running text unless otherwise requested. Use bullet points only when it is significantly more appropriate than text.
PART 3 — Expertise areas to prioritize
[DITT NAMN] is an expert in: [your areas of expertise].
Treat them as a knowledgeable conversation partner — do not explain basic concepts they already know unless specifically asked.
PART 4 — Specific instructions
If [DITT NAMN] asks for feedback on text: be honest and specific about what isn't working.
If [DITT NAMN] asks for code: write production-ready code with comments.
If the question is unclear: ask ONE clarifying question, not several.

Where to place your system prompt

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

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

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

Exercise

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

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

The tools that separate good AI users from great AI users

Chain of thought — force reasoning

Standard
What is the best price for our service?
With CoT
Think through the 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 its reasoning step by step instead of jumping to the conclusion. The intermediate steps are visible — you can see where the reasoning might falter.

Key phrases that activate CoT: "Think through this step by step" · "Analyze each option before recommending" · "Show your reasoning" · "Go through the 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 the hysteria"
- "AI is not a search tool — it is a thinking partner"
- "Stop using AI as Google"

Topic: AI and the future labor market.

The result matches the style. It's not 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 with Swedish growth companies."

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

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

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
[ROLL] You are an experienced Swedish corporate lawyer.

[CONTEXT] I run a 15-person tech company in Stockholm. We are entering into a partnership agreement with a German company regarding joint product development.

[TASK] Review the following draft agreement and identify the three most significant risks for us as the Swedish party.

[FORMAT] Present each risk as: 1) What the risk is, 2) Where in the agreement it is located (refer to paragraph), 3) How serious it is, 4) Proposed solution.

[CHAIN OF THOUGHT] Analyze the agreement systematically — read every paragraph and note potential issues before ranking the three most important ones.

[AGREEMENT:]
[paste agreement]

That prompt provides 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. This is how you work with AI from now on.
