About AIBussin

Build useful systems with modern AI.

AI is becoming part of the interface between people, software and information. AIBussin is where I build and test practical systems around that shift — then write down what survives contact with reality.

What AIBussin is

A working surface, not a blog

AIBussin is not primarily a news blog or a tutorial feed. It is the place where practical AI ideas are developed into working systems, reusable solutions, experiments, technical books, tools, prompts and articles — with each form feeding the others.

01

Solutions

Ideas packaged around real problems with working implementations, from prompt systems to browser-native AI.

02

Books

Long-form, first-principles treatments of agents, context, memory, language, retrieval and AI engineering.

03

Tools

Interactive applications — prompt libraries, builders and working sessions — for doing the work, not just reading about it.

04

Articles

Experiments, technical notes and ongoing explorations that support the larger systems and books.

How the work develops

From question to working result

Not every project follows a rigid process, but a recurring pattern connects most of the work here: prototype an idea, test it against reality, keep what the evidence supports, and turn the durable result into something other people can use.

01

Question

Start from a precise question about how an AI mechanism behaves, not from a tool looking for a use.

02

Experiment

Prototype with code, measure what happens, and revise. Failures are recorded, not hidden.

03

System

Turn what works into a working system with explicit state, boundaries and observable behavior.

04

Solution, book or tool

Publish the durable result in the form that fits: a solution page, a book chapter, or a tool.

Books

The books work through difficult subjects — agents, context, memory, language, embeddings, browser AI, debugging — from first principles. Each one is developed alongside the experiments and systems it describes.

Featured book

Applied AI

Engineering Intelligence Into a Reliable Process

How does model intelligence become reliable engineering?

Build from a callable model to explicit context, durable state, controlled actions, independent verification, and a deterministic runtime that decides what happens next.

Browser AI From First Principles cover
Featured book

Browser AI From First Principles

What happens when the browser itself becomes the AI runtime?

Build browser-native AI from the capability boundary upward: local models, observability, WebMCP tools, agent security, and a user-owned browser policy engine.

Solutions

Where ideas become usable

Solutions are the differentiator of this site: each one connects a real problem to its mechanism, implementation and supporting evidence.

The site

Different entry points into the same work

Start from the depth you need, then move between explanation and application.

About the author

Ernan Hughes

I am a programmer and independent author. I build and test AI systems, then write about what survives contact with reality — working from first principles and keeping the evidence separate from the claims.

“I believe AI will become the primary way we interact with information and technology.”
The wider ecosystem

Three sites, one body of work

AIBussin is part of a small ecosystem of independent sites. They overlap deliberately — each exists because it answers a different question.
