How to write AI prompts — the practical guide
Most bad AI answers aren't the model's fault, they're the prompt's. Four moves change almost everything — no "prompt engineering" course, no 47-euro pack needed.
A good language model is like a capable intern: the clearer the instruction, the less you correct afterwards. A vague request gives you the average of half the internet — correct, but interchangeable. These four moves raise quality more than any tool switch.
The four moves to a usable prompt
1 Say who you are and who the text is for
"Write a text about taxes" is a dice roll. "I'm an accountant writing for self-employed tradespeople with little time — explain the small-business scheme in plain words" gives you something usable. Context isn't an extra, it's half the instruction.
2 Set the format
Say what should come out: five bullets, a table, a paragraph under a hundred words, an email with a subject line. Without a format you get prose you then have to take apart again.
3 Show an example
A single example of your style says more than three paragraphs of explanation. Attach an old post, an earlier email or a phrasing that sounds like you, and say: "in this tone". The model imitates — so give it something good to imitate.
4 Iterate instead of rolling again
The first answer is a draft, not a finished product. Say specifically what's off: "too salesy", "shorter", "the second point is wrong, cut it". Two or three targeted corrections get you further than ten "do it again".
The difference in one example
Same typing effort, a night-and-day difference in the result. The strong prompt contains role, audience, tone, format, length and topic — exactly the things the model would otherwise have to guess.
Five mistakes that make prompts weak
- No context: "Write me X" with no role or audience. The model guesses — and guesses average.
- Several tasks at once: research, write and shorten in one prompt. Split the steps.
- No format: you get prose where you wanted bullet points.
- Politeness padding: long preambles don't help. Clarity beats filler.
- Giving up instead of refining: switching tools at the first mediocre answer instead of giving a specific correction.
Copy template to adapt

These six lines replace most bought prompt packs. You tell the model once who you are and what you want — it does the rest.
Do you need a ready-made prompt pack?
Usually not. Ready-made prompts save typing time but don't replace understanding — and many expensive packs are nicely wrapped obvious advice. If you still want a collection of tested German prompts to copy quickly, I've put together an honest one.
