Prompt vs Product vs Assistant vs Agent
Every car needs an engine, a co-pilot, and a blueprint. On Sigrix, each listing type plays a different role in your AI journey.
The car analogy
The big picture
Every concept on Sigrix maps to a part of a car. Here's the full picture.
In detail
Prompt / Persona
The core instruction that powers everything. Without it, nothing moves.
A prompt is a single-shot instruction that returns an answer or draft. A persona shapes the tone and behavior. Together, they're the engine under the hood—the raw power that every assistant and agent depends on.
Assistant
Guides you during the ride. You stay in control while it handles navigation.
An assistant is a guided flow where you stay in the loop. It follows your steps, asks for approvals at key moments, and adds instructions for tone or guardrails. Think of it as someone in the passenger seat helping you navigate—you're still driving.
Agent
You set the destination. It handles the rest.
An agent is a composed AI system that runs from point A to point B with minimal user interaction. It bundles persona, prompts, and routing into one deployable configuration. Just like a self-driving car—you say where to go, and it gets you there.
Product
A ready-made plan. Follow it and receive a fully assembled car.
A product bundles instructions, tools, and assets into one packaged experience. Think of it as a blueprint—someone has already designed the car. You just follow the plan and get a working result, no engineering required.
