AI agents & RAG
Assistants that search your own documents and cite the source in every answer, with per-document permission checks.
AI agency, GermanyYour AI. Local, not in someone else’s cloud.
As an AI agency we build AI agents, RAG search and custom models – with our own code since 1999. On request everything runs on-premise, so your data stays in-house.
01
An agency with its own code
Many AI agencies just chain together third-party cloud services and bill per request. We take the other route: we write the code ourselves and, where it fits, use local models that run on your own hardware.
That means full data control, predictable cost and no lock-in to one provider. In the end the source code, the documentation and all access details belong to you.
What we build in detail is on the services page. This page is about AI in particular.
02 · What we build as an AI agency
AI that fits your data.
Local AI models
A language model running on your own hardware instead of someone else’s cloud. Your data never leaves the house.
Custom models & training
A small model trained on your task – fast, cheap to run and with no token billing.
AI automation
Recurring steps – classifying, summarising, routing – handled by AI, with a human approving the critical ones.
03 · Why Quell-Code
The difference from a cloud agency.
Our own code, not a kit
We write the code ourselves, understand it and stand behind it. No subscription platform, no black-box kit – in the end it all belongs to you.
Local & on-premise
Your AI runs on your hardware or your server. That is the difference from agencies that only chain together third-party cloud services.
Data sovereignty & GDPR
Company data stays in-house. Especially for documents with personal data, that is the calmer route legally and for security.
Honestly sized
We measure up front what your hardware can do instead of promising speed. If what you have is not enough, we say so.

Questions first
What does an AI agency do?
An AI agency plans, builds and operates AI solutions for companies – from AI agents and RAG search to custom models and automation. At Quell-Code the code is written in-house and can run entirely on-premise.
Does our AI have to run in the cloud?
No. We focus on local and on-premise models that run on your own hardware, so you keep full control of your data.
Who does Quell-Code work for?
Mainly SMEs in Germany, Austria and Switzerland – mostly remotely, on site when needed.
Do we own the solution in the end?
Yes. You receive the source code, the documentation and all access details. There is no dependency on a subscription platform.
