What is Build With Billy?

Build With Billy is a personal brand and community from Billy Lewis — a self-taught builder running AI systems across a handful of small businesses from a farm in New Zealand. It’s a free newsletter, a free monthly community call, practical guides, and a couple of products (the Brain Kit and a cohort) for people who want to build real things with AI rather than just chat with it.

How much does AI consulting cost in New Zealand?

AI consulting in NZ ranges from free community workshops to $297–$497 for an AI Opportunity Map diagnostic, to custom retainers for managed automation. Build With Billy offers a free monthly community call, a time-savings calculator, and paid consulting starting at $297 NZD.

Do I need technical skills to use AI in my business?

No. Most AI tools have free tiers and simple interfaces. Build With Billy’s clients typically start with $0/month tools like Claude, Airtable, Supabase, and Vercel. Everything is explained in plain English for regular people doing meaningful work.

Can a small NZ business afford AI automation?

Yes. Most AI tools have free tiers. Build With Billy’s clients typically start with $0/month tools and only add paid services when the ROI is proven. The AI Quick Wins checklist shows 5 automations you can set up for free today.

A living knowledge base that remembers every decision, insight, and pattern. It grows with your work and gives your AI permanent context. Available as a starter kit from Build With Billy.

FOR PEOPLE WHO LIVE IN THE CHAT, NOT THE TERMINAL

Your AI has amnesia.You don't need to code to fix it.

Give Claude a memory — without ever leaving the chat you already use. No terminal. No “black screen.” No setup headache. About ten minutes. Free.

Get free access

No card. No download. Works in the Claude you're already paying for.

This is for you if…

You do most of your thinking with AI in the chat window — and you like it there.

Every time you open a new chat, you're re-explaining who you are and what you're working on.

People keep telling you to “use Claude Code,” and the terminal feels like a wall you don't want to climb.

You're a creator, coach, founder or operator — not a developer — and you want the leverage without the learning curve.

You tried the “proper” setup once, got overwhelmed, and quietly closed the tab.

If you nodded at even one of those — you're in the right place.

You had a brilliant conversation with your AI on Monday. By Tuesday, it's a stranger again.

Every day, the same quiet tax:

You explain your business, your voice, your offers — again. For the fifth time this week.

You finally got a great answer. The chat ended. It's gone, somewhere in 60 other threads.

You want it to just “know you” — but every conversation starts from zero.

Someone said “just use Claude Code.” You opened a black screen, felt your stomach drop, and closed it.

The cruel part: the more fluent you already are in chat, the harder that jump feels.

Everyone tells you the answer is to “move to Claude Code” — the terminal, the setup, the API keys. For most people who live in the chat, that's a cliff, not a step. So they bounce off, decide AI “isn't for them,” and quietly fall behind.

Here's the thing nobody told you: you don't have to leave chat to give your AI a memory.

MEET BRAIN LITE

The same friendly Claude you already talk to — now with a memory.

Brain Lite runs your brain right inside the Claude chat you already use. You're not learning a new tool or leaving the friend that gets you. You're upgrading it — so it remembers you across every conversation.

Stay in chat

No new app, no terminal, no black screen. If you can talk to Claude, you can do this.

It remembers you

Who you are, what you're building, the decisions you've made — carried across every chat, not lost overnight.

Your apps just work

Whatever you've already connected in Claude comes along for the ride. Nothing to wire up.

WHY THIS EXISTS

“The second I installed the brain, my jaw dropped. If you can speak it and articulate what you want, there's probably a way it can come to be. It's an absolute game changer.”

— G, Build With Billy community

I built Brain Lite overnight after our last community call. Someone sharp — fluent in chat, building a real business — hit the chat-to-code wall and nearly walked away. That felt wrong. The magic shouldn't be locked behind a terminal. So I made the easy door.

It's genuinely this simple

No magic words, no config files. Four small steps, about ten minutes.

Make a Project in Claude

A Project is just a space that remembers — everything in it shares one memory.

Paste in the instructions

One block of plain text turns Claude into your brain. We give it to you.

Start talking

By voice or text. It asks three quick questions, then it knows you.

Your apps come along

Calendar, drive, docs — whatever you've connected already works.

Show me the exact steps — free

Set up your Brain Lite

You'll need Claude (the Pro plan or higher, so you get Projects). That's the only requirement.

GET FREE ACCESS

Tell me a little about you and I'll unlock the full visual setup — it helps me make this genuinely useful for you.

WHEN YOU'RE READY FOR MORE

Brain Lite remembers. The Pro brain gets to work.

Brain Lite lives in chat. The Pro brain lives in Claude Code — it connects your tools, runs your pipelines, and gets things done while you sleep. The leap from AI that answers to AI that does. Most people start here on Lite and graduate when they're ready.

The Brain Starter Kit is $27 today — going up to $54 soon.

Questions you probably have.

Is it really free?

Yes. Brain Lite is free. You set it up inside the Claude you're already paying for — there's no extra subscription, no card, no download. The only ask is a couple of quick questions so I can keep making it genuinely useful.

Do I need to know how to code?

No. That's the whole point. If you can hold a conversation with Claude, you can set up Brain Lite. It's a Project in the chat app, a block of text you paste in, and you're away. No terminal, ever.

What do I actually need?

A Claude account on the Pro plan or higher (so you get Projects), and about ten minutes. That's it.

Where does my data live? Is it private?

It lives in your own Claude account, in your Project — same place your chats already are. Nothing extra is sent anywhere, and no third-party service touches it. It's your memory, in your account.

Will it really remember me between chats?

Yes — that's the difference. A normal chat forgets you the moment it ends. Brain Lite keeps your context in the Project, so every new chat inside it already knows who you are and what you're working on.

How is this different from the $27 kit?

Brain Lite lives in chat and is the easiest possible start — free. The Pro brain (the Starter Kit) lives in Claude Code: it connects your tools and does work on your behalf, even overnight. Same idea, more power. Start on Lite, graduate when you want it doing things for you.

Stop re-explaining yourself
to your AI.

Give Claude a memory tonight — in the chat you already use, in about ten minutes. No code. No risk. Free.
