SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Create social posts, newsletters, and short-form video briefs that are calibrated to a creator's voice and the mechanics of each platform, removing guesswork about truncation points, hashtag strategy, safe zones, and hook placement.

Core Features & Use Cases

  • Voice analysis: Extracts cadence, sentence length, emoji density, POV, and signature phrases from example posts to match tone and style.
  • Platform mechanics & validation: Produces content tailored to LinkedIn, X, Instagram (feed and Stories), TikTok, and newsletters with checks for truncation windows, character limits, hashtag guidance, and one-CTA rules.
  • Production & repurposing: Generates scene briefs for 9:16 TikTok videos with FFmpeg composition guidance, plus a repurposing waterfall to turn long-form posts into threads, carousels, stories, and video assets.
  • Use Case: Turn a 1,500-word article into an X thread, an 800-char LinkedIn post, an Instagram carousel outline, and a 20–30s TikTok scene brief with FFmpeg composition notes.

Quick Start

Generate a platform-optimized LinkedIn hook, a 6-tweet X thread, an Instagram caption with a 125-character visible hook, and a 4-scene TikTok scene brief from my 1,500-word article.
