Repurpose a Blog Post into Social Media Content with AI

You wrote a solid article. Maybe it took you three hours. Maybe it took you three days. Either way, it is sitting on your blog while LinkedIn, your newsletter, and three other platforms your audience actually checks daily get nothing. The math on that is bad.

The fix is not to write more. It is to get more out of what you already wrote. One article should produce a LinkedIn post, a Twitter thread, an Instagram caption, and a newsletter blurb. Usually it does not, because rewriting the same content four times for four different platforms is tedious enough that most people skip it.

This prompt does the rewriting in about thirty seconds.

Getting the Input Ready

The input is your article. That is it.

You can paste the full text directly into the Cowork prompt box. Plain text works fine. HTML or Markdown is fine too. If your blog post is already published and you want to grab clean text, use your browser’s reader mode or paste from your CMS editor.

A few things that help:

• Include your article title. Claude will use it when crafting hooks.
• If you have one particular angle you want emphasized (the stat in paragraph four, the story in the intro), say so at the top before the article text: “Lead with the finding in paragraph four.”
• If your LinkedIn voice is more formal than your Twitter voice, note that. The default prompt calibrates for each platform, but a quick note overrides the defaults.

One thing to be realistic about: the output is a first draft. The LinkedIn post will be competent. With a small edit or two, it can be genuinely good. Plan for a five-minute review pass on each piece, and the total time is still well under an hour.

The Prompt

With your article ready to paste:

You are a social media strategist and content writer. I will paste a blog post or article. Turn it into a complete social media content pack.

Deliver each of the following:

**1. LinkedIn Post**
Length: 150-250 words
Tone: Professional but human -- written by a real person sharing a genuine insight, not a brand announcement
Format: Start with a strong first line (no 'I'm excited to share' openers). Use short paragraphs. End with one clear question or call to action.

**2. X (Twitter) Thread -- 5 tweets**
Tweet 1: Hook (the most surprising or counterintuitive point from the article)
Tweets 2-4: One key insight per tweet, each under 280 characters
Tweet 5: Takeaway + link placeholder ([LINK])

**3. Instagram Caption**
Length: 100-150 words
Tone: Conversational and direct
End with 5 relevant hashtags

**4. Newsletter Blurb**
Length: 60-80 words
Format: 1-2 sentence tease + 'Read more: [LINK]'
Tone: Matches the newsletter of someone who knows their audience well -- not promotional

Rules:
- Pull insights directly from the article -- do not invent claims not found in the original
- Vary the angle for each platform; do not just copy-paste the same sentence four times
- Avoid marketing buzzwords and AI cliches

The rule about varying the angle per platform is the most important line in the prompt. Without it, you get the same two sentences reformatted four different ways. With it, the LinkedIn post leads with a professional observation, the Twitter thread leads with the most counterintuitive claim, and the Instagram caption goes for something more immediate and human.

What You Get Back

The output arrives in four clearly labeled sections. Here is what to expect from each.

The LinkedIn post will open strong (the prompt bans the usual weak openers), use short paragraphs for mobile readability, and end with a question or call to action. Read it out loud. If it sounds like a press release, soften one or two sentences.

The Twitter thread will front-load the hook. Tweet one is almost always usable without editing. Tweets two through four each carry a single point from the article. Tweet five is the closer with a link placeholder. Replace [LINK] with your URL before posting.

The Instagram caption will be shorter than you think you want and probably the right length. Instagram is not a reading platform. The five hashtags at the end are suggestions; replace any that feel generic with ones specific to your niche.

The newsletter blurb is intentionally brief. It is designed to tease, not explain. If your article has a good second hook that did not make the LinkedIn post, add it here manually.

One Extra Pass Worth Making

Before posting anything, run a quick check on the LinkedIn post and Twitter thread for facts. The prompt instructs Claude to pull directly from the article and not invent claims. That instruction works well, but Claude can occasionally restate a nuanced finding with more confidence than the original warranted. If you made a careful “this suggests X” argument in the article, check that the social versions did not flatten it into “X is true.”

This is a two-minute check that protects you from having to post a correction.

Extending the Workflow

If you want a YouTube description or a short-form video script intro added to the pack, append the request to the prompt before the article text. Something like: “Also produce a 5. YouTube Description (150 words, include three keyword-rich phrases relevant to the topic).”

The same approach works for podcast show notes, press release summaries, or any other format your content distribution needs. Specify the format, length, and tone. Claude will produce it from the same source material.

For teams that publish frequently, this workflow is worth standardizing. One shared prompt template, one folder, a consistent five-minute review step. Most content teams get two or three times the platform coverage from each piece of content without adding meaningful time to the process.
