DUNKELKAMMER

Here is where AI projects are made

A small, silent computer on your desk with Claude Code installed. You talk to it from your own laptop or tablet. Your texts, offers, invoices and website live in your own home, not in someone else's cloud.

What's in the box

Everything is decided and identical on every unit, so it just works and stays cheap to support.

The computer

Lenovo ThinkCentre Tiny, refurbished: about one litre in size, silent, around 10 W at idle. 16 GB RAM, fast NVMe SSD. Comes with its power brick and an Ethernet cable.

The software

Debian Linux with Claude Code ready to go. You reach it from any browser on your Mac, PC or iPad; a remote desktop is there for the rare times you need a window. Security updates install themselves.

Your data stays here

A labelled 64 GB backup stick in the box: every night the machine copies your files onto it. Nothing of yours is stored with us.

A starting point

Project folders with example prompts for texts, offers and invoices, plus a short note describing your business so the AI knows who it works for from the first minute. A one-page printed quick guide.

Not included: monitor, keyboard, mouse. The box has no screen of its own by design; you work from the devices you already have.

How it goes

From the first e-mail to your first real project in about two weeks.

You write

A short mail: your first name, what your business does in three lines, and whether you work on a Mac, Windows or iPad. We reply with a fixed quote.

We build

Your unit gets the image, your name and your starter folders, runs an hour of tests, gets its sticker and ships. Or you pick it up in person.

Session one

Two hours on a video call: plug it in, log in, connect your Claude account, first three prompts, Wi-Fi if you want it. You set your own password.

Session two

One week later, another two hours: your real task. A website change, a set of documents, an offer template. Then four weeks of small questions by mail, included.

Want someone to keep an eye on it afterwards? A care plan for 24 € per month covers monthly check-ins, updates and half an hour of help. Optional, cancel any time.

Who it's for

People who run something small and want an assistant that lives with them, not in a browser tab.

Tradespeople and solo businesses

Offers, invoices, e-mails, the odd letter to the tax office. Dictate the gist, get a finished document, keep the customer data at home.

Owners of a small website

Change a text, add a page, fix a typo, without waiting for the agency. If we built your site, the box comes with it already checked out and ready to publish.

The curious

You have heard what these tools can do and want to try it properly, with someone explaining the first steps and a machine that is yours.

Not for

Gaming, video editing or running large AI models locally. This is a small office computer built to be quiet and reliable, not a graphics workstation.

Questions

The ones we get asked first.

Why a separate computer? I could run this on my laptop.

You could. The box exists so the setup is done once, done right, and stays out of your way: it is on all the time, it does not slow your laptop, nothing breaks when you update your own machine, and your files are in one place with a nightly backup. It is also much easier to explain over a video call when every unit is identical.

Do I need to know Linux or the command line?

No. You open a browser tab, type in plain German or English, and the AI does the file work. The two sessions cover everything you need for daily use, and the quick guide covers the rest. If you get stuck, you write us.

What does it cost per month?

A Claude subscription on your own account, from about 20 € per month, paid directly to Anthropic. We never resell AI usage. Our optional care plan is 24 € per month and can be cancelled any time. Electricity is roughly one euro per month.

Where does my data go?

Your files stay on the box and on the backup stick in your home. What you type into the AI is sent to Anthropic for processing, like with any AI service; that part is between you and them. We hold nothing of yours after the sessions.

Can you get into my machine?

Only during the sessions and only with a remote link you can switch off with one command, which is printed on the quick guide. The browser terminal is password-protected and not reachable from the internet.

Can I just buy the computer without the sessions?

Ask. The setup is the same either way; the sessions are what makes it work for people who have never used a tool like this. If you already have, we can quote just the box and setup.

Three units are being prepared. Put your name on the waiting list, or write us a line with your questions.
