Post Writer Sms

This is a platform-native social media post writer that handles LinkedIn, Twitter/X, Threads, Bluesky, Facebook, Instagram, TikTok, Pinterest, and YouTube Community posts. It pulls from a voice context file to match your actual writing style, then generates posts with the right structure, character count, and cultural norms for each platform. The guidance is detailed: LinkedIn gets hook-body-CTA with line breaks every 1-2 sentences, Twitter stays under 280 with zero fluff, Threads reads like texting a smart friend. It knows where hashtags help and where they kill reach, when links suppress distribution, and how truncation works on mobile. Use it when you need a single standalone post, not a thread or carousel.
