Draft five LinkedIn posts in one sitting
The core of the pack. A three-step sequence that turns five chosen ideas into five finished posts in your voice, then edits them as a set so the week does not feel repetitive.
What you'll fill in
- [voice sample] 2-3 things you have written that sound like you (posts, emails, even Slack messages) e.g. “Paste 150-400 words of your own writing”
- [five ideas] The five post ideas for the week, one per line, with format e.g. “Mon - story - profitable vs cash...”
- [audience] Who the posts are for e.g. “Small service business owners”
- [call to action] The soft action you want readers to take, if any e.g. “Reply "checklist" and I will send the weekly cash check”
Copy the prompt
Step 1 — Teach it your voice
I am going to have you write LinkedIn posts for me this week. First, learn how I write.
Here are samples of my writing:
"""
[voice sample]
"""
Analyze the samples and describe my voice in a short checklist: sentence length, how I open, words and phrases I use often, things I never do (for example jargon, exclamation marks, emojis), how formal I am, and how I use humor if at all. Keep it to 8-10 bullets.
Do not write any posts yet. End by asking me to confirm or correct the checklist.
Step 2 — Draft all five posts
Using my voice checklist (with my corrections), write five LinkedIn posts for [audience], one for each idea below: [five ideas] For every post: - Hook in the first line, under 150 characters, that makes someone tap "see more". - 120-250 words. Short paragraphs of 1-2 sentences, with white space between them. - One clear point per post. Cut anything that does not serve it. - Use concrete details from my ideas. Where a detail is missing, write [ADD: what's needed] rather than inventing it. Never invent numbers, clients or results. - End with either a question that invites a real answer or this call to action, used in at most two posts: [call to action] - No hashtags in the body. Suggest up to 3 relevant hashtags under each post separately. Label each post with its day and format.
Step 3 — Edit the week as a set
Now act as a strict editor reviewing all five posts together, the way a reader would experience them across one week. Check and fix: 1. Repetition: same opening structure, same words, same ending style. Vary them. 2. Voice drift: any sentence that does not sound like my checklist. Rewrite it. 3. Fluff: cut filler words and any line that only restates the previous one. Aim to cut 10-15% of words. 4. Promise vs payoff: does each post deliver what its hook promises within the first 3-4 lines? 5. Placeholders: list every [ADD: ...] I still need to fill. Output the five final posts, ready to paste, followed by a short change log (3-5 bullets) and the list of placeholders.
How to use it
- Open a new chat in Claude (the others work too).
- Paste step 1 and replace every [bracket] with your details.
- When it replies, paste the next step in the same chat.
- Review the output, check any facts, and edit to taste.
Why Claude: Claude handles a long writing sample and keeps your voice consistent across five drafts; ChatGPT works well if you keep the sample short.
Tips
- Your best voice sample is something you wrote quickly to a real person, not your polished About page.
- Fill the [ADD: ...] placeholders with real details. They are what make a post feel lived-in.
- Schedule posts for the mornings your audience is at their desks, and change the order if a timely topic comes up.
Example output
Voice checklist (confirmed)
- Short sentences, often under 12 words.
- Opens with a moment or a plain statement, never a question.
- Uses "honestly" and "here's what we did".
- No exclamation marks, no emojis.

MONDAY - Story
Best sales month ever. Nearly missed payroll.
A client called me on a Tuesday afternoon. Her revenue report looked fantastic. Her bank balance did not.
Here's what happened: she had invoiced a lot of work in March. Almost none of it had been paid yet. Payroll was due Friday.
Profit is what you earned. Cash is what you can spend. In a growing business those two drift apart fast.
We fixed it with two changes: deposits up front on new projects, and a weekly 10-minute look at money coming in versus money going out.
She made payroll. [ADD: one line on how she felt / what she said]
If sales are up and money feels tighter, you are not imagining it. Reply "checklist" and I'll send the weekly cash check we use.
Suggested hashtags: #smallbusiness #cashflow #bookkeeping
Change log
- Varied openings: Tuesday's post now starts with a list item instead of a scene.
- Cut 41 words across the week.

What do I need to fill in?
Replace each bracket with your own details: [voice sample], [five ideas], [audience], [call to action]. The more specific your input, the more useful the result.
Is this prompt free?
Yes. Copy it above and use it as often as you like. It is one of the free samples from the A week of LinkedIn posts in one session pack.
