How this works
This workflow helps creators, solopreneurs, SaaS founders and agencies generate and publish social media posts across Instagram, Facebook, LinkedIn and X without manual drafting each time. It pulls brand guidelines from a connected Google Sheet, uses OpenAI to develop ideas into platform-specific captions and images, then posts directly through the official APIs. The key step is the AI agent that turns a brief into structured, ready-to-publish content for multiple channels.
Use it for regular posting schedules where brand tone stays consistent and you need ideas refreshed weekly. Skip it if your content requires heavy custom visuals or immediate crisis responses, as the flow works best with pre-approved brand briefs and scheduled batches rather than real-time tweaks.
