In today’s issue, we cover:

1. What is OpenAI Agent Builder

2. Where ChatKit Fits In And Why It’s a Big Deal

3. Lovable Prompt Template: How to Combine Agent Builder & ChatKit

4. How to Implement Client Tools for Agents to Control Your App Step-by-Step

This guide will help you:

• Understand what’s feasible.

• Suggest better ideas for your product.

• Build a unique solution for your AI PM portfolio.

During the upcoming Office Hours (on Tuesday, always recorded) we will:

• Briefly discuss using agents as tools in n8n (the old topic).

• Build a chatbot from scratch using Agent Builder and ChatKit step-by-step.

This is a premium issue. I haven’t seen anyone demonstrating this setup. And lost a few hairs building templates that actually work, so you do not have to code.
