# Build Your Own Jarvis

The memory-first AI system that remembers you, works while you sleep, and builds its own tools

Everyone wants Jarvis. Almost everyone builds the wrong thing. The memory-first system from someone who actually runs one: nearly 1500 sessions, real accidents, real guardrails. No code.

[Buy on Amazon.com →](https://www.amazon.com/dp/B0H8JMF7V7)$8.99

The book is in English.

## Why I wrote it

This is the book closest to what you see on the rest of this site. Jarvis is not a voice toy, it is a system: an AI assistant with memory that remembers you, works in the background and builds its own tools. I run one, and this book is what that actually looks like, including the mistakes and the guardrails that came out of them. Concept and practice, without a line of code.

## What is inside

How a memory-first AI system is built, why most Jarvis attempts fail, and the guardrails that came out of nearly 1500 real sessions. Concept and practice, no code.
