The 20 Most Popular Prompts – how to use them

The prompts on this page cover the requests people make most often at home and at work: writing an email, summarising a long text, understanding a topic in plain language, polishing a CV, finding an Excel formula. Each one contains the four parts of a good prompt: context, a clear task, limits and the format you want.

Do not leave the bracketed fields empty; the AI fills missing information with its own guesses. The sample outputs were produced with Claude and are only there to give you an idea. Your result will vary between tools and over time; always check figures, dates and names yourself.

  • Say who the output is for and why.
  • Ask for a length and format: bullet points, three paragraphs, a table.
  • If the first result is off, ask for a small correction instead of starting over.
  • Do not include personal data, passwords or confidential company information.

Example: a weak prompt and a strong prompt

Weak prompt

Write me an email.

Strong prompt

Write a short email telling a customer their order will be two days late because of a courier backlog. Tone: apologetic but professional. New delivery date: 24 October. At most 100 words. Suggest a subject line too.

Sample output generated with Claude

Hi [Customer name],

Because of a backlog at our courier, your order will arrive two days later than planned. The new estimated delivery date is 24 October.

We are sorry for the delay. Your order is packed, and we will send you the tracking number as soon as it ships.

If you have any questions, just reply to this email.

Thank you for your patience.

Kind regards,
