Zero Kelvin Auto Yield (0KAY) is a lightweight, AI-powered social media automation kit designed specifically for makers, farmers, scientists, and small businesses. Built on Make.com, Google, and OpenAI, 0KAY lets you design posts in your voice, schedule content across up to 4 platforms, and approve each post before it goes live—all without subscription fees or black‑box systems. The DIY version is entirely free, while the fully hosted service is available for $10/month after a 30‑day free trial—you only pay after you’ve used it. Expandable, transparent, and built for doers.
