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.
