Writing separately for nine social platforms is a full-time job. This guide shows you a systematic approach to writing once and adapting efficiently — so your content performs on LinkedIn, Twitter/X, Instagram, TikTok, Facebook, Bluesky, Threads, Pinterest, and YouTube without starting from scratch each time.

Write the source version in your natural form
Start by writing the complete, unformatted version of your content — the full thought, the full story, or the full explanation — without worrying about any specific platform. This is your source content. It might be 500 words, a set of bullet points, or a series of observations. The goal at this stage is completeness and accuracy, not format. Do not trim for Twitter or expand for LinkedIn yet.
Identify the core message in one sentence
Distill your entire source content into a single declarative sentence. This is your platform-agnostic core message. Everything you post on every platform is a different expression of this sentence. Having this single-sentence version prevents the problem where different platform versions drift away from each other in meaning.
Understand the structural conventions of each platform
LinkedIn: open with a hook, develop with structured points or narrative, close with a question or call to action. Keep lines short with spaces between paragraphs. Twitter/X: open with your most interesting claim, use 1–3 sentences per tweet in a thread, number threads. Instagram: hook in the first 125 characters, use line breaks, end with a call to action, hashtags after the main copy. TikTok: curiosity-gap opener, direct address ("You might not know this..."), very short sentences. YouTube: keyword-first title, information-dense description with keywords in the first paragraph.
Write the LinkedIn version first
LinkedIn typically requires the most developed version of your content — a full 200–500 word post with a hook, body, and close. Writing this version first forces you to develop the argument fully. This version becomes the richest source for extracting all other platform versions.
Compress the LinkedIn version for Twitter/X
Take your LinkedIn post and identify its 3–7 most standalone points. Each becomes one tweet in a thread. The opening tweet is your sharpest, most striking claim. Subsequent tweets expand each point. The closing tweet is your takeaway or call to action. Threads should not simply be a cut-up version of the LinkedIn post — rewrite each tweet to function independently and to flow sequentially.
Restructure for Instagram and TikTok
For Instagram, take the core message and rewrite it in second person with a direct hook: "Here's what most people get wrong about [topic]." Use line breaks after every 1–2 sentences. End with a clear call to action. For TikTok, strip everything to a curiosity-driving opener that works as a standalone hook — this is what goes in the caption. The actual TikTok content (if it is a video) is a separate format question from the caption.
Build a personal style guide for each platform
After writing for multiple platforms for 4–6 weeks, review which of your posts performed best on each platform. Identify the structural and stylistic patterns in the high-performers. Document them in a short personal style guide — 5–10 rules per platform. Use this guide as a quality check before scheduling any post. Over time, these patterns become intuitive and the adaptation process gets faster.

Paste your source content into Postprism. Click "Adapt for all platforms." The AI generates a Facebook post, Instagram caption, Twitter/X thread, Bluesky post, Threads update, LinkedIn post, TikTok caption, YouTube description, and Pinterest pin simultaneously — each following the structural conventions of the platform.
Character limits tracked in real time per platform
The Postprism editor shows character counts for every platform simultaneously. See exactly how much space you have left on each platform and where each version will be truncated in the feed.
