A free tool that turns a single announcement into native posts for LinkedIn, X, TikTok, Instagram, Threads, and Facebook — each in the voice that platform rewards, with hashtags and posting times. One command in Claude, or one paste into any AI.
The one job, done
/cross-post does exactly that.
Give Claude one announcement and it writes all six posts — each tuned to the platform, with hashtags and a suggested posting time. No blank page, no rewriting the same news six ways.
Turn one announcement into native posts for six platforms — LinkedIn, X, TikTok, Instagram, Threads, and Facebook — each written in the voice that platform rewards, with hashtags and posting times. No blank page, no rewriting the same news six ways.
Two ways to run it:
• On a paid Claude plan? Install the free Social Media Manager plugin and type /cross-post. One command, done.
• Any other AI — free Claude, ChatGPT, Gemini? Copy the built-in prompt (a sample cross-post sheet is prefilled), paste it in, swap your details.
Inside: the full prompt with a sample cross-post sheet, the one-command Claude path, built-in accuracy rails, and a two-minute setup walkthrough. Opens in your browser.
AI writes a fresh cross-post sheet every time — read it before it goes out. The rails keep it on track, not replace your review.
Want the rest of your content workflow handled — content calendars, caption batches, engagement replies, campaign recaps? The Social Media Manager AI Prompts pack is the full system: 38 ready-to-run skills. This free tool is a real slice of it.
