100% On-premises · No cloud · Your data stays in-house

Your company knowledge.
Instantly available.

Many employees already turn to ChatGPT – and unintentionally upload internal documents to the cloud. Our AI assistant answers the same questions from your own documents: with a source you can check, on a machine in your own building.

€0
Subscription & per-user fees
No license subscriptions, no per-user fees: you pay once for the setup, at a fixed price. Updates and maintenance are available through an optional support contract.
Seconds
instead of digging through folders
The answer appears word by word, with a source you can check. How long it takes depends on hardware, AI model and the scope of the question — in the free demo you will see it live with your own documents.

data in the cloud

Sound familiar?

Knowledge is your company's most valuable resource – but hardly anyone can find it when they need it.

⏳

Hours spent searching

Minutes, analyses and reports are scattered across folders and network drives. According to the McKinsey Global Institute (2012), knowledge workers spend nearly 20% of their working time looking for internal information or the right colleagues.

🚪

Knowledge walks out the door

When experienced employees leave, they take their knowledge with them. New hires need months to get up to speed.

⚠️

Shadow AI at work

Anyone who needs an answer fast pastes contracts or minutes into public AI services. A real GDPR risk – and management usually never finds out.

The solution: your own AI assistant

Ask questions, get answers – with source references, in seconds, right in the browser.

💬

Natural chat

Employees ask questions in plain language. The AI answers with substance and cites its sources.

🎯

Answers only from your documents

In the default strict mode, the AI relies solely on your documents. If something isn't in there, it says so instead of guessing. A traffic light on every answer shows how well the passages match.

🔍

Semantic search

Understands meaning, not just keywords. Finds "budget cut" even when the document says "cost-saving measure".

📄

Common document types

PDF, Word, Excel, PowerPoint, CSV, text and Markdown – and even audio recordings are transcribed and indexed automatically.

🏠

100% on-premises

Runs on your own server. No data ever leaves your network. No cloud, no external APIs.

🛡️

Privacy built in

Audit log, personal-data anonymization, deletion concept and GDPR documentation – designed for GDPR-compliant operation and ready for your data protection officer.

👥

Multi-user

All employees access it through the browser. An admin manages users, roles and — if you wish — who gets to see which documents.

🔄

Swappable models

New AI models are installed with a single command. No dependency on any single vendor.

🎓

Faster onboarding

New employees ask the AI instead of their colleagues – from internal procedures to machine manuals. Onboarding gets noticeably faster.

📥

Watched folders

New files are detected, processed and indexed automatically – without anyone having to think about it.

What it looks like in practice

Ask a question, get an answer with its source – and an honest “not in your documents” when they don't contain the answer.

Real screenshot of Real KI Systems in strict mode (German interface): asked about the budget decision in the Q3 meeting, the AI answers with its source and a confidence light; asked about the marketing budget for 2028, it replies that this information is not contained in the documents.

It's that simple

Installed and configured on site in one day – depending on volume, your documents are fully searchable within one to two days.

1

Feed in knowledge

Your documents, minutes and analyses are indexed once. New files are added with a click.

2

Ask a question

Employees open the browser, type their question and get a precise answer – with a reference to the original source.

3

Knowledge grows

Every new document becomes part of the knowledge base. The more you feed in, the more valuable the system becomes.

Why not ChatGPT?

The crucial difference: your data stays with you.

More than AI: software & automation

The AI assistant is often just the beginning. Wherever workflows eat up time, systems don't talk to each other or the right software simply doesn't exist, we make your business more efficient – with solutions tailored exactly to the way you work.

🛠️

Custom software development

Tailor-made applications instead of Excel sprawl and isolated point solutions: internal tools, desktop and web applications – built around the way you work, not the other way round.

⚙️

Workflow automation

Eliminate recurring manual work: generating reports, transferring data, processing documents – it runs automatically, reliably, even at three in the morning.

🔗

Interfaces & integration

Your systems finally talk to each other: we connect ERP, databases, Office and industry software – no more duplicate data entry and copy-paste.

📊

Data analysis & reporting

Scattered data becomes a solid basis for decisions: automatically updated evaluations and dashboards instead of hours of copying things together.

🤖

AI in your processes

Use AI where it really saves time: analyzing, classifying and transcribing documents – locally on your hardware and privacy-friendly, integrated into your existing workflows.

🧭

IT consulting & process analysis

We look at your workflows, find the time sinks and prioritize by benefit. Honest recommendations instead of buzzword bingo – even when the answer is "you don't need that".

How we work

No off-the-shelf projects – but always the same reliable process.

1

Analysis

Free initial consultation: where is time being lost? Which workflows are painful? We listen and take a close look.

2

Concept

4

Ongoing care

We don't leave you alone after go-live: training, documentation and, if you wish, ongoing support under a maintenance contract.

⚡ Automated report delivery 📑 PDF data extraction into your ERP 🧾 Quote & invoice generator ✅ Digital checklists & forms 🏭 Warehouse, maintenance & inspection tools 🔄 Legacy data migration

Typical projects – many can be delivered within a few days.

Frequently asked questions

Answers to the most important questions from IT managers and executives.

Do we need our own server for this?

A normal desktop PC with an NVIDIA GPU is enough. No server room or rack required – a quiet PC under a desk will do. Cost: currently approx. €1,600–2,000 depending on configuration and market prices.

Does it also work without an internet connection?

Yes, completely. After the one-time installation (downloading the models), no internet connection is needed anymore. Ideal for companies with strict network policies.

How long does the setup take?

On-site installation: one day. Processing your documents: one to two days, depending on volume. Then acceptance test, introduction and sign-off – you are usually productive within a week.

Does the system also help with onboarding new employees?

Yes – this is one of the biggest practical benefits. New employees ask the AI directly and get answers from your own documents, with source references to read up on. This takes pressure off experienced colleagues and shortens onboarding considerably.

What if an employee asks something they shouldn't?

Employees only see their own conversations; the administrator can view all of them. Logins, chat usage (without the content of questions), uploads and admin actions such as user and permission changes, deletions and backups are recorded in the audit log. The admin can remove accounts, reset passwords and control who sees which documents.

Can every employee query everything – including salaries or personnel files?

Not if you don't want them to. You group documents into areas, such as HR or management, and block those areas for individual employees. Blocked content then appears neither in their answers nor in sources, search or file view. Administrators still see everything; every change to the restrictions is recorded in the audit log.

Our files are on a network drive – do we have to move anything?

No. The system mirrors the folders you choose at regular intervals and processes new files automatically – your filing structure stays as it is. SharePoint content can be included via export, Markdown notes (e.g. from Obsidian) can be imported. Other systems can be connected via the programming interface.

How many employees can use the system?

There is no limit on user accounts. How many employees can ask at the same time without waiting depends on the GPU: several questions are answered in parallel, further ones queue briefly. We size the hardware to your headcount in the initial consultation – and the pilot shows it with your real users.

Does the AI ever make things up?

It can be wrong – which is why, by default (strict mode), it relies solely on your documents and says openly when they contain nothing on the subject. In our test, it declined every question the documents could not answer instead of guessing. Every answer shows the original source and a traffic light indicating how well the passages match; you can check important statements with one click. Try it in the demo: ask something your documents don't cover. (Technically, the search combines meaning and keywords and re-sorts the hits with a reranker.)

Do you also take on smaller automation projects?

Gladly – it's often the small automations (reports, data transfers, document processing) that bring the fastest time savings. After a free initial consultation you receive a fixed-price quote; many of these projects can be delivered within a few days.

We already have an IT department – is that a good fit?

Yes. We complement your team on a per-project basis wherever time or specialist knowledge is short. Software we develop specifically for you is handed over cleanly with documentation, source code and training – your IT can keep working on it. The AI assistant comes with a perpetual license and keeps running even without a maintenance contract.
