Hey Product Hunt — I’m Brett, the solo builder behind CyWire. I built CyWire because I kept running into the same problem while adding AI features to web apps: prompts were easy to write once, but hard to reuse reliably. CyWire lets you build Master Prompts — reusable prompt blueprints that define the inputs, instructions, constraints, and JSON output structure for an AI feature. The idea is simple: you build the AI-powered site, tool, agent, or workflow. Your users interact with it. CyWire gives the AI feature a stronger foundation so the output stays structured, bounded, and usable by your app. My first real test was PushPad, an education prototype that uses CyWire-generated Master Prompts to create micro-lessons and course scaffolds from user input. That helped prove the core idea: one strong structured prompt with a clear output contract can often be cheaper, faster, and more consistent than a long multi-step prompt chain. CyWire is still early, but free accounts are open. I’d especially love feedback from developers, agencies, product teams, and builders working on AI features, agents, structured outputs, or JSON-based workflows. Would love to hear what feels useful, confusing, or missing.
