J.A.R.V.I.S.
How I built my personal AI assistant in 4 days with Claude Code

One ZIP package, right after payment
The “J.A.R.V.I.S.” e-book
PDF, A4, about 60 pages, in German, Italian or English – your choice. 12 chapters with the original prompts, the mistakes I made and a checklist for every chapter – plus the whole architecture on one page, an honest A/B/C/D status, a 30-day plan and a glossary.
Prompt Pack for Claude Code
26 copy-ready prompts (in the language of your e-book) – the 15 from the prompt library plus the 11 original prompts from the chapters, numbered, each with a title and a “when to use it” note. As Markdown (.md) and as a short PDF in the same black-and-gold style.
Quick guide (README.txt)
Where to start, how to handle secrets, personal licence, contact – in the language you choose.
Version 1.0, October 2026. This is not software to install and not the complete source code: it is a hands-on book with code excerpts and prompts you use to build your own system with Claude Code.
Five things the book walks you through, step by step
Deploying with Docker and 7 checks (gates) – any failure rolls back automatically to the previous version.
Login with scrypt + TOTP, and a router that blocks payments, signatures and outgoing messages until you give an explicit yes.
Running Claude Code “headless” with read-only rights – with a voice that answers sentence by sentence and can be interrupted mid-sentence (barge-in).
Telegram around the clock, encrypted backups and a watchdog – with no extra running costs.
15 ready-made prompts (the prompt library) and a 30-day plan to rebuild everything yourself.

Who it's for – and who it isn't
It's a fit if …
- You run a business or freelance without a dev team and want an assistant of your own.
- You already use Claude Code – or want to start – and want to see a real project from the inside.
- You take security seriously: approvals, secrets, backups, no autopilot where money is involved.
- You read German, Italian or English – you pick the language at checkout.
It's not a fit if …
- You expect a finished app to install.
- You're looking for passive-income promises – there are none here.
- You never want to touch a terminal or a server.

Frequently asked questions
What format does the package come in?
A ZIP file (about 7 MB) with the e-book as a PDF (A4, about 60 pages), the Prompt Pack as Markdown and PDF, plus a quick guide (README.txt) – all in the language you choose at checkout. Readable on any computer, tablet or phone.
What language is the e-book in?
Available in German, Italian and English – you choose the language at checkout. The Prompt Pack and the quick guide come in the same language as the e-book.
Do I need to know how to code?
No – but you shouldn't be afraid of a terminal. Claude Code writes the code; you decide, check and approve. For the server part, basic knowledge of VPS and Docker helps – the book explains every step in plain language.
What does Claude cost on top?
Claude Code requires your own Anthropic account (subscription or API credit), which is not included in the price. Check current pricing with Anthropic. In the book everything ran on a subscription and a server I already had, with no extra running costs – that is a first-hand account, not a guarantee.
