CleanExpo/Synthex — reverse-engineered prompt

Build me SYNTHEX, a polished AI powered social media agency platform for businesses, creators, influencers, and marketing agencies.

I want users to sign in, connect their social accounts, define their brand voice, generate platform specific posts with AI, schedule them on a visual content calendar, and track performance in a clean analytics dashboard. It should feel like one place to plan campaigns across Instagram, TikTok, X, LinkedIn, Facebook, YouTube, Pinterest, Reddit, and Threads.

Include useful features like trend and hashtag ideas, competitor insights, approval workflows for teams, client visibility, reports, dark and light mode, subscriptions, and a professional responsive design that works well on desktop and mobile. The experience should feel modern, trustworthy, and agency grade, not like a basic scheduler.

Use the existing TypeScript Next.js style stack from this repo, with Supabase or Postgres, AI integrations, auth, billing, and background jobs where needed. Look up current docs online if you need to.
