Writing prompts for Grok

Copy-ready prompts for everyday writing: shorter drafts, calmer messages, cleaner structure and letters that get a reply. Fill in the brackets and send.

Most writing at work and at home is not literature. It is the email that has to say no without starting a feud, the report nobody will read past the first paragraph, the cover note, the apology, the complaint. The twenty prompts below are built for that kind of text: shortening a draft, fixing the tone of a message you wrote while annoyed, turning scattered notes into a structure, writing letters that get answered, and explaining a technical subject to people outside your field.

Each prompt has blanks in square brackets. Replace them with your own details before sending, because the more specific the context, the less generic the result. Grok 4.20, the default model in our chat, is quick and handles nearly all of these well. One prompt suggests Grok 4.3 Thinking, which reasons before answering and is better at restructuring a long, tangled document. Another uses image understanding: attach a clear photo of handwritten notes and Grok will type them up and tidy them, marking words it could not read.

A few cautions. Grok writes fluent text even when a fact is wrong, so check names, dates and figures before anything goes out. It cannot see the internet, so it does not know your company's latest policy or this week's news unless you paste them in. Keep passwords, account numbers and other people's private details out of your messages.

How to adapt these prompts

  • Name the reader: "my landlord", "a hiring manager", "the whole team".
  • Paste a sample of your own writing when the voice matters, and ask Grok to match it.
  • Set a hard length, such as "under 120 words", rather than "short".
  • Ask for two versions in different tones and combine the best lines.
  • Reply with what's wrong, such as "too stiff" or "the second paragraph is weak", instead of starting over.

    Cut a draft by a third

    Shorten the text below by about a third without losing any fact, figure or deadline. Remove repetition and warm-up sentences first, keep my tone, and then tell me in one line what you removed so I can put anything important back: [paste text]

    Say no without burning the bridge

    Put the conclusion first

    Here is a report I wrote: [paste report]. Most readers will only read the opening. Write a new first paragraph of no more than four sentences that states the conclusion, the main reason for it and what I am asking the reader to do. Then suggest which sections could move to an appendix.

    Restructure a long, tangled document

    The document below grew over months and now jumps between topics: [paste document]. Propose a new structure with headings in a logical order, show where each existing paragraph should move, and point out duplicated or contradictory passages. Don't rewrite the text yet.

    Type up handwritten notes

    I've attached a photo of my handwritten notes about [topic]. Type them up word for word first, then give me a tidy version with headings and bullet points. Where you can't read a word, write three question marks instead of guessing.

    Explain a technical topic to outsiders

    I work in [field] and need to explain [technical topic] to [audience, e.g. parents at a school meeting]. Write a 200-word explanation with one everyday comparison and no jargon, ending with a sentence on why it matters to them. Then list the two questions they are most likely to ask.

    Write a complaint that gets a reply

    Write a complaint to [company] about [problem]. Facts: [order number, dates, what happened, what I already tried]. State clearly what I want, [refund, repair or replacement], and by when. Stay polite and factual, and keep it under 200 words so a busy support agent reads all of it.

  9. 09

    Apologise properly

    Help me write an apology to [person] for [what I did]. Name the mistake specifically, skip excuses and the phrase 'if anyone was offended', say what I will do differently, and make it sound like a person, not a press release. Keep it short.

  10. 10

    Write a cover email for a document

    Write a short email to send [document] to [recipient]. In three or four sentences, say what the document is, the one part they should look at first, and what I need from them by [date]. Friendly, but brief enough to read on a phone.

    Turn bullet points into flowing prose

    Turn these bullet points into one or two well-linked paragraphs for [purpose, e.g. a newsletter]. Add connecting words so the logic flows, keep every point, and don't add claims I didn't make: [paste bullet points]

    Send a reminder that assumes good faith

    Write a toast people will remember

    Write a [length]-minute speech for [occasion, e.g. my sister's wedding]. Weave in these memories: [two or three stories]. Mix warmth with a couple of gentle jokes, avoid stories only three guests would understand, and end with a line everyone can raise a glass to.

    Write instructions a beginner can follow

    Write step-by-step instructions for [task] for someone who has never done it. Number the steps, begin each with a verb, warn about the most common mistake at the step where it happens, and finish with a short check that tells them they're done.
