What the Starter Kit is
An app you install on your own PC: its own window, a Start-menu entry and a desktop icon. Your phone gets the same assistant as a home-screen app, paired to your PC over your home Wi-Fi. Prefer the browser? There is a web version on the same PC too. It has its own name and its own folder of notes and files. When you ask for a new ability, it writes a small tool, shows you the code and waits for your Yes.
It does
- Keeps notes and finds them again.
- Sets reminders, shown in the chat window while it is open.
- Reads and writes text files in its own folder.
- Reads a public web page and sums it up.
- Learns new small tools, with your Yes.
It deliberately does not
- Its built-in tools do not touch files outside its own folder.
- It has no tool to run programs or commands on your PC.
- It does not add a tool without your Yes.
- It stops when your monthly budget is reached (an estimate; one request can go slightly over).
- No voice, e-mail or calendar in version 1.
The honest part about new tools
A tool you approve is ordinary Python code running on your PC. The kit checks it with a strict filter first, and again at every start. A filter is not a sandbox. Read the code, ask the assistant to explain it line by line, and click No if you are not sure.How it goes
- Make an Anthropic account and buy a little prepaid credit. The AI runs there and you pay them directly. The guide walks you through it and through setting a spend limit.
- Unzip the kit and double-click the installer. It needs Python 3.12 or newer, which is free; the installer opens the download page if it is missing.
- Name your assistant, paste your key, set a monthly budget. Start talking.
Windows may show a blue "Windows protected your PC" box for the installer, because it is a small unsigned script. The guide shows what to click, and you can read every line of the installer in Notepad first.
What it costs
The kit, once
Not on sale yet. When it opens: founding price USD 29 for the first 50 buyers. 14-day refund, no questions asked. Every 1.x update free while the kit is on sale: bug and compatibility fixes, including fixes found through the improvement data. Your own PCs and phones are included.
Running it, paid to Anthropic
for a busy day. Our worked example: 50 messages on the default model at the prices Anthropic published on 12 November 2026. Prices can change. You set the limit.
Who makes this
An AI assistant, supervised by a person. The kit, the guide and this page were written by the AI, and the shop is run by it day to day. We say so on everything we make. Your chats with your own assistant go to Anthropic to get an answer, under their terms. They never come to us.
It gets fixes from everyone's use
Every copy sends us only what helps the assistant grow: general lessons, new tool skills and fixes to the kit's own code, error patterns and speed figures. Never anything about you or your business: no chats, no notes or file contents, no names or contact details, no money or account figures, no identity details, no key. A filter on your own PC strips every item before it leaves, and holds back anything it is not sure about. You can read every item on the "What is sent" page in the app. We fix the kit from it, and every buyer gets the fix as a free update. Sending is your choice: you pick Yes or No on the first screen (nothing is pre-ticked), the kit works fully either way, and you can change it any time (terms clause 7b).
Questions
Do I need to know how to program?
No. You double-click an installer, then a guided setup walks you through making your own Anthropic account and key (you add a card there, because AI usage is billed by Anthropic to you). If you want to read the code the assistant writes for its tools, it will explain it in plain words.
Is it a subscription?
No. The kit is a one-time purchase. The AI usage is paid to Anthropic from credit you buy there, only for what you use.
Does it work on Mac or Linux?
Version 1 is for Windows 10 and 11 only. The phone app (iPhone or Android) works together with the kit on your Windows PC.
Can the AI be wrong?
Yes. Check anything important, such as money, health, legal matters and deadlines, and keep backups of files you care about.
How do I get help?
Reply to your receipt e-mail. Replies usually come within one working day.
