Build Your Own Trinity

An Easy To Follow, Step by Step Guide to Building a Personal AI Agent

Build your first useful personal AI assistant, starting with one clear task and a step-by-step plan.

What is inside?

Define your assistant’s instructions, organize useful information, set boundaries, and test its work. Visual checkpoints help you compare your progress with an example. Choose a no-code assistant in an existing AI product or a starter Python agent with one controlled, read-only tool.

By Justin Alan DeWitt and Darleen DeWitt-Palmer.

The Python route requires a computer, an API account, and setup. The no-code route uses an existing AI product. Provider subscriptions or API usage may have separate costs. This guide does not promise a fully autonomous system. See Amazon for current price and availability.
