The simplest way to build an AI voice agent. Just write your instructions in plain language — no flowcharts, no nodes, no complexity. Your agent follows your prompt and handles any conversation naturally.
Single Prompt is the fastest way to create an AI agent. Instead of building complex conversation flows, you simply describe how your agent should behave in natural language.

Include exact details like business hours, pricing, and common questions with their answers.
Tell the agent what to do when it doesn't know something. "If unsure, offer to transfer to a human..."
