Feature 2 of 5 in our Launch Week series

Crafting effective prompts for LLM-based agents can often feel unclear or overly complex. Many developers waste valuable time iterating through trial-and-error, struggling to get their agents to behave consistently. That’s why we built the AI Prompt Composer—helping you quickly build prompts that produce reliable, predictable agent behaviors.

Why It Matters

Prompt creation shouldn’t feel like guesswork. With the Prompt Composer, you can:

  • Rapidly Build Prompts: Create and iterate on prompts quickly, directly within the dashboard, saving you hours in experimentation.
  • Leverage Built-in Expertise: Access proven best practices without needing to dig through extensive documentation.
  • Refine with Precision: Easily adjust and fine-tune prompts, making it straightforward to shape your agent's responses clearly and effectively.

What's New

The Prompt Composer is just our first step in simplifying prompt engineering. Looking ahead, we're already iterating on new enhancements:

  • Expanding to automate other key dashboard tasks.
  • Integrating Prompt Composer closely with test suites, automatically surfacing suggestions for improvements based on real-world test outcomes.

Why It Matters to Us

We build tools that solve real problems faced by developers and users. Every feature we ship, including the Prompt Composer, starts with feedback from the community. We aim to simplify complexity and provide clarity, enabling you to build agents more effectively.

Getting Started

  1. Log in to your Vapi Dashboard and create your Vapi Assistant
  2. Use Vapi AI Prompt Composer and see how the prompt changes
  3. Review our Docs for more detailed instructions and best practices.

Stay curious, keep iterating, and let’s build something real together.
