Use Case

Make internal knowledge instantly findable.

Your company's knowledge is scattered across wikis, documents, tickets, and legacy systems. A RAG search answers questions in natural language, with source citations and full respect for access permissions.

Interactive demo

See it running, not just described.

In the Belegcenter, our interactive demo, you can put questions to 47 freshly posted documents from accounting, ERP, and the warehouse: the answers are computed live over the data, connect the systems, and cite their sources. That is exactly how a knowledge search works over your own data.

  1. 47 documents from three sources
  2. Read out, check, post to the right system
  3. Ask across systems

01

What is RAG?

RAG (Retrieval-Augmented Generation) combines a search across your own content with a language model. The answer is based on sources found in your data, so every statement is backed by a source. That keeps it verifiable and current.

02

Quality features

  • Every answer comes with a source citation, backed up and traceable
  • Access control: everyone sees only what they are allowed to see
  • New documents are searchable immediately; the search keeps itself current
  • Data quality as a prerequisite: we help clean up the sources

Sources

Typical knowledge sources we connect

One search across what you already have.

  • Wikis and Confluence
  • SharePoint and file storage
  • Manuals, guidelines, and technical documentation
  • Tickets, emails, and service cases
  • Legacy systems and databases

Approach

Our approach

How we build a knowledge search that gives dependable answers.

  1. 01

    Connect and prepare the sources.

    We connect your wikis, file storage, and legacy systems, clean up the content, and prepare it for search.

  2. 02

    Retrieval with a permission filter.

    For every question, the system pulls the relevant passages from your sources, and only the ones the user is cleared for.

  3. 03

    Answer with a source citation.

    The language model formulates the answer from the passages it found and points to the source, so every statement can be verified.

  4. 04

    Evaluation and operation.

    We measure answer quality against real questions, tune it, and keep the search current in operation.

03

RAG or fine-tuning?

For internal knowledge search, RAG is almost always the right choice: cheaper, easy to keep current, and with source citations. Fine-tuning pays off more for style and format, not for factual knowledge.

Experience

Why appDev

The appDev team has been building backend and integration software for over 15 years, including for health insurers, banks, and industry. Bringing together data from many systems, mapping permissions cleanly, and working in a way that stays traceable is everyday business there.

That is exactly what a knowledge search needs to earn trust inside a company. You speak directly with the permanently employed senior engineers who build your solution.

FAQ

Frequently asked questions

What is RAG?

RAG connects a search across your own documents with a language model. The answer draws on the sources it finds, which makes it backed up and current.

RAG or fine-tuning, which is better?

For factual knowledge and internal search, RAG is usually better: cheaper, easy to keep current, and with source citations. Fine-tuning is more suited to a fixed style or format.

Does everyone see all content?

No. Access control makes sure users only see sources they are cleared for.

How do you handle hallucinations?

Every answer draws on documented passages from your sources and cites them, so you can check them. If the source coverage is too thin, the system makes that clear. That keeps the search dependable.

Which sources can you connect?

Wikis, SharePoint, file storage, manuals, tickets, and legacy systems. We clarify which ones matter for you at the start.

How long does the rollout take?

A first, useful knowledge search is ready in the pilot within six to eight weeks. We scope the exact extent precisely up front.

Getting started

How you get started

You start with a Discovery for €1,900, creditable. We look at your sources and sharpen the use case. You get a binding fixed-price quote. The pilot then brings the search into production in six to eight weeks, from €39,000.
