Write Once: Markdown for Multiple Social Platforms

Why a single markdown draft beats rewriting the same post twelve times—and how to respect each network’s limits.

Cross-posting the same copy everywhere sounds efficient until Instagram strips your bold, LinkedIn wants a professional tone, and Discord expects markdown literally. One markdown source can still be the right hub—you just need per-platform export.

Start with a platform-agnostic draft

Draft the core message in markdown: headline idea, three bullets, call to action. Avoid platform-specific jokes until you branch. That core becomes the seed for LinkedIn, X, Threads, and others.

Adapt instead of duplicate

Trim for X; expand examples for LinkedIn.
Remove unsupported formatting for Instagram and TikTok captions.
Use Discord or Reddit formatters when code blocks matter.

Markdown2Social keeps separate previews and counters per network so you are not guessing whether the paste will break. Guest mode keeps drafts in the browser; sign in when you want the same posts synced across devices.
