I will build a private local ai knowledge system


About this gig
Your AI. Your documents. Your computer. Nothing leaves your house. I build private AI knowledge systems that answer questions from YOUR documents contracts, manuals, notes, research running 100% locally on your machine. No cloud, no monthly API fees, no data leaks. Perfect for lawyers, consultants, doctors, authors and any business that takes privacy seriously (GDPR-friendly by design). Why me? I'm a German engineer & author. I run my own publishing business on exactly this system 25,000+ document chunks, answering in seconds. I don't sell theory. I sell what I use every day. Everything is set up remotely via Zoom. You need ZERO technical knowledge you watch, I build, you learn. WHAT YOU GET - Ollama installed with the right AI models for your hardware - RAG system indexing your documents (PDF, Word, Markdown and more) - Clean chat interface to talk to your knowledge base (Standard/Premium) - Documentation + handover session Your data never leaves your computer. Not even I can see it after setup. Not sure which package fits? Message me first I'll tell you honestly, even if the smaller one is enough.

FAQ
What do I need on my side?
A computer with at least 8GB RAM (16GB recommended) and your documents in digital form. Send me your specs before ordering — I'll confirm honestly if your machine can handle it.
Which document formats work?
PDF, Word, Markdown, plain text and more. If you have a special format, message me first.
Is my data safe?
Yes — that's the whole point. Everything runs locally on YOUR machine. Your documents never touch a cloud server, and after the handover I have no access to anything.
What's the difference to your $40 gig?
The $40 gig installs the AI engine only. This gig adds the full knowledge system: your documents get indexed and the AI answers from them. This is the complete setup.
Do you offer ongoing support?
Premium includes 30 days of support. After that, you can book me again anytime — but the documentation is written so you won't need me.
