Module 4 · Build #2: The Client Hub
What you're building: your client memory
Remember the Client Bio One-Pager we pitched back in the Client Management pillar of Automate Your Business with AI? This is the module where you actually build it — a private hub that remembers every client, every note, every appointment, and briefs you before you walk into the room.

What REALLY Happens When You Type Localhost?
The problem this fixes
Think about where everything you know about a client actually lives right now. A few emails in your inbox. A scribbled line in a notes app. A detail their partner mentioned once that you’re fairly sure you’ll remember. And then the meeting arrives, they sit down, and you get that small cold moment of walking in blank — scrambling to recall what you talked about last time, what you promised, what matters to them.
It’s not a memory problem. It’s a storage problem. The information exists; it’s just scattered across five places and none of them talk to each other. That’s exactly what we’re going to fix.
What you’re building
A small private app that runs on your own computer, with three simple views:
TODAY
Who you’re seeing, key facts at a glance.
CLIENTS
Everyone, searchable in two seconds.
CLIENT PAGE
One person, everything, newest first.
And the part you’ll use most: a big paste-box on each client’s page. After a meeting you dump your messy notes into it — typos, half-sentences, whatever — hit save, and move on. No forms, no fields to fill in, no friction.
Where your data lives — and why that matters
Here’s the important part. All of this client information lives in plain, readable files inside your own folder on your own computer. Not on someone’s server. Not in a company’s database. No account, no login, no monthly fee. You can back the whole thing up by copying one folder, and you can open the files and read them yourself if you ever want to.
If you’re a therapist, lawyer, doctor, financial adviser — anyone bound by client confidentiality — this design is a real advantage. Here’s the honest, precise version of why. Your data is stored only on your own machine: no company database, no account to log into, no server that can be breached and dumped online. That alone is far harder to say about most cloud tools built for the same job.
One distinction worth being straight about: when you ask Claude to read a client’s file to write a briefing, the words in that file are sent to Anthropic’s servers to be processed — the same as every other time you’ve used Claude in this course. It’s not stored there as a product database, but it is processed there. On the consumer Claude plans, chats can also be used to improve future models unless you turn that off — so if you handle privileged information, open Settings → Privacy and switch off the “help improve Claude” option.
And the plain-language rule for confidentiality-bound work: before you put privileged client details anywhere an AI reads them, check your professional obligations — exactly as you would for any cloud tool. Local-first storage removes the biggest risk; it doesn’t remove your duty to think.
The new idea in this build: memory
Your first real tool — the proposal builder in Build #1 — made something fresh every time you asked, then forgot everything the moment it finished. This one is different: it remembers. It stores data and keeps it, meeting after meeting, month after month. That’s the one genuinely new concept in this module — a tool with memory — and once you’ve got it, a huge range of business tools open up to you.
Set up the folder
- Inside your
my-toolsfolder, create a new folder namedclient-hub(lowercase, no spaces). - Open Claude Code and point it at that
client-hubfolder. - Turn permissions on, the same way you did in the setup module, so Claude can build without stopping to ask on every step.
You have an empty my-tools/client-hub folder open in Claude Code, permissions on, chat box ready. Next lesson, one prompt turns it into a working app.
