A Cowboy's Guide to Setting Up Your Own Garage AI Agent

Vol. I · Guide to Local AI

📖 By Marcus Eigh 🔒 Privacy-First ⚡ DRM-Free

The Problem

Cloud AI is Watching You.

Every prompt you type into ChatGPT, Gemini, or Claude goes to a server you don't control, gets logged, and potentially used to train their next model. If you work in healthcare, law, finance, or any field with confidential data — that's a serious problem.

Even if privacy isn't your main concern, those subscriptions add up fast. $20/mo per employee across a team of 10 is $2,400 a year for something you could run free on hardware you already own.

"The best AI setup is the one that runs on your hardware, uses your data, and never phones home. This book is your step-by-step blueprint to get there — even if you've never touched a terminal."

Common Questions

FAQ

Do I need a powerful computer? +

Not necessarily. The book covers what hardware you need for different model sizes. An M1 Mac with 8GB RAM can run very capable models. The book helps you match the right model to your hardware so you're never running something your machine can't handle.

Is this for Mac, Windows, or Linux? +

All three. Ollama runs on macOS, Windows, and Linux. The book's primary examples use macOS (Apple Silicon), but all core concepts and commands apply across operating systems. Windows and Linux notes are included throughout.

Do I need to know how to code? +

No coding required for the core setup chapters. You'll use the terminal (command line), but every command is spelled out. The RAG and MCP chapters involve some configuration files, but nothing that requires programming knowledge.

What formats does the download come in? +

PDF (great for desktop reading and printing) and EPUB (great for e-readers like Kindle, Kobo, or the Books app on iPhone/Mac). Both are DRM-free — download them once and keep them forever.

Is this the same as the Amazon version? +

Yes — same content, direct from the author. Buying here keeps 100% of the revenue with Cowboy AI LLC rather than splitting it with Amazon. You also get DRM-free files you can use on any device.
