CyWire is a B2B platform for businesses and developers who build AI-powered products. You use our Master Prompts to guide the AI features on your site or tool—so your end users consistently get reliable, structured output.
Our Master Prompts are a structured JSON instruction system with defined variables, rules, and output schemas that get consistent, machine-readable output from your AI models—on any platform, for any user.
CyWire master prompts are structured JSON blueprints that give every AI feature a defined set of instructions, constraints, and output rules — so your AI returns results in the same structure every time.
Most AI will not know your rules. That is a process problem that CyWire solves.
What Is a CyWire Master Prompt?
Master prompts are structured JSON blueprints that give every AI feature a defined set of instructions, constraints, and output rules — before the model ever runs. Not an entire site engine or chat prompt. A single feature blueprint your AI follows every time. What is a master prompt? Full definition and example
