AI search for large specialist corpora: to the right source with chapter and version

Associations, professional societies and public bodies have thousands of pages - and visitors who cannot find the right one. The knowledge navigator understands the intent and routes to the right source, the right chapter, the current version. It formulates solely on the basis of sources it has found.

The situation

The answer is on your site. Nobody finds it.

The common pattern: the answer has long been in your corpus - nobody finds it because the question is phrased differently from the heading.

  • Visitors ask in their own words

    Full-text search finds pages that contain words. Without the technical term you get twelve hits or none and have to sort them yourself.

  • Superseded versions turn up too

    The most common practical failure in specialist corpora is not the wrong answer but the outdated one. An archived version that merely ranks lower resurfaces on the next search.

  • The questions land with people

    Whatever is not found in the corpus arrives as an email or call at the office or the support desk, often the same question yet again.

A real classification

What an answer looks like

The assistant in the bottom right of this site runs on the same machinery, indexed on our own corpus. Below is its unedited output for a real question - nothing about it has been touched up.

What the visitor typed

„We want to migrate from VMware to Proxmox and secure operations.“

What the system does with it

  1. Understand the request
  2. Match offer building blocks
  3. Search the site knowledge
  4. Produce the classification

Classification

WZ-IT reads your project as a strategic migration from a VMware environment to Proxmox VE, to reduce licence costs and regain control over virtualisation. This is not only about the technical move but also about securing operations through high availability, backup and disaster recovery.

The main solution combines the migration itself with building a stable operational base. Proxmox VE handles virtualisation, while backup, monitoring and network infrastructure secure stability. The migration runs in stages: analysis of the current environment, test migration, cutover and final operational hardening.

WZ-IT delivers planning and architecture, including risk analysis and rollback strategy. In operations we take on monitoring, CVE watching, backups and updates.

Matching building blocks

  • MigrationVMware to Proxmox migration

    Direct fit for migrating VMware ESXi/vSphere to Proxmox VE, focused on planning, test migration, cutover and operational hardening.

  • InfrastructureProxmox & private cloud

    Supports building a Proxmox-based private cloud with high availability, backup and disaster recovery as the target architecture.

  • OperationsManaged operations

    Securing operations after the migration through monitoring, backups and updates is central to the project.

So we can start where it matters

  1. 01

    How many ESXi hosts and VMs are currently in use?

  2. 02

    What are the requirements for high availability, backup and disaster recovery?

  3. 03

    Should workloads be migrated one to one or restructured?

The assistant handles these projects too - ask it yourself:

The assistant is in beta and can classify a request wrongly, which is why every classification carries a route to a human. For knowledge corpora, the sourced passage with chapter and version replaces the offer building blocks.

Use cases

What a knowledge navigator is built for

Product catalogue

Visitor asks

I need something that meets a specific requirement - which of these fits?

Navigator

The navigator clarifies the decisive attributes in one or two follow-up questions, routes to the matching catalogue entries and links the data sheet and the contact.

Funding database

Visitor asks

Is there any funding for our project?

Navigator

It narrows down by region, project type and eligibility and routes to the matching programme - with deadline, version and a link to the application. It never promises an approval.

Guidelines and expert knowledge

Visitor asks

What does the current version say on this topic?

Navigator

It routes to the right chapter of the valid version, names the version date and flags superseded editions. Judging the individual case stays with the professional.

Support knowledge

Visitor asks

Why does this not work for me?

Navigator

It routes to the matching help article or how-to - and where nothing fits, straight into the contact form instead of sending the visitor further through the archive.

Internal policies

Visitor asks

How is this handled here?

Navigator

It routes to the valid policy or form template including its version, instead of an outdated PDF that is still linked somewhere.

Members and audiences

Visitor asks

What applies to my case?

Navigator

It distinguishes audiences - member, professional, press, general public - and routes each into the right area, including the contact and booking path.

Approach

How the knowledge navigator comes about

The effort is not in the model, it is in the structure: what belongs to the corpus, what is archive, and which intent leads where?

  1. 01

    Corpus analysis

    Inventory from the sitemap, samples per content type, exclusion rules for archived versions. The result is a written assessment with the number of processable documents, the outliers and what should be tidied up first.

  2. 02

    Connect the sources

    Sitemap, CMS API and document stores are opened up. First we clarify what belongs to the valid corpus, what is archive and who owns which area editorially.

  3. 03

    Structure the content

    Content is split by chapter and enriched with metadata: area, language, date, version. Archived editions are excluded, not merely ranked lower.

  4. 04

    Define the guided paths

    A curated catalogue defines which intent leads where, where a follow-up question is asked and where a human takes over. That is editorial work, not model selection.

  5. 05

    Verify answer quality

    We test with real questions from your actual intake and check every answer against the cited source. Wrong paths are corrected in the catalogue, not talked away in the prompt.

  6. 06

    Operations and upkeep

    A daily diff keeps the index current. The unanswered questions are the most valuable output: they show where the corpus is missing content.

What associations, professional bodies and public authorities additionally need

  • Accessibility: The widget has to be operable by keyboard and screen reader; since 28 June 2025 the German accessibility act applies to many digital services. We check focus order, labels, contrast and status messages and document the state.
  • Multilingualism: Separate corpora per language rather than machine translation at runtime. If content exists only in German, the navigator says so and links the German version.
  • Audience separation: Members, professionals, press and the general public need different slices of the same corpus.
  • DPA and technical measures: The data processing agreement and the description of measures exist before the project starts, not after.
  • Exit: If you switch, you get catalogue, configuration and index out, in a documented format.

Guardrails

What the navigator may do - and what it may not

With public expert knowledge, a wrong answer costs more than a missing one. That is why the limits are architecture, not phrasing, anchored in the index rather than in the prompt.

GuardrailHow it is enforced
Answers only from cited sourcesWithout a hit in the corpus there is no answer, only a handover. Free model knowledge is not an admissible source of answers.
Citation is mandatoryEvery statement carries a link, chapter and version date. An answer without evidence is discarded rather than delivered.
The valid version comes firstWhat currently applies is found first; archive is excluded from the search space. If a version has been superseded, the navigator names both and says which one applies.
Escalation to a humanIf nothing fits or the question becomes case-specific, the navigator visibly routes to the contact form or booking page - not into an endless loop.
No legal, medical or financial adviceCase-specific assessments are rejected before the model call. Inputs are checked for personal data beforehand. The navigator names the authoritative source and the way to the responsible professional.
LoggingQuery type, chosen path, source and result are logged - without storing personal input as raw text. The log lives in your system; you decide who may see it.
Switchable off at any timeThe navigator is a component of your site, not a replacement for it. It can be disabled per area or entirely without making content unreachable - important while a corpus is being revised.

Result

What you have at the end

Not access to a platform, but a system that belongs to you and whose parts you can name.

  • Connected sources

    Your corpora, connected through a CMS interface, sitemap or file storage - documented as to which areas are included and which are deliberately not.
  • Structured content

    Split by chapter, with title, section, date and audience in the metadata. That is the basis of every sourced answer.
  • Defined guided paths

    Which requests lead to which areas and where the navigator hands over. We build the catalogue and train your editors; changing paths afterwards is a task in your system, not a ticket to us.
  • Answer quality report

    Share of sourced answers, share of handovers, unanswered requests by topic and most cited sources - measured against test questions from your real enquiry traffic. The unanswered topics are your editorial backlog.
  • Embedded widget

    Integrated into your site, in your visual identity, without rebuilding your CMS.
  • Operations documentation

    How re-indexing works, where the configuration lives, what you get out if you switch providers.

The corpus analysis regularly surfaces problems that have nothing to do with AI: broken sitemap references, unreachable files, duplicates between language versions. You get told about those whether or not the project happens.

Price

What determines the price

The build costs from €14,900 excl. VAT. We name the fixed price for your corpus and ongoing operations with index maintenance and reporting after the corpus analysis. These six points determine it:

  • The number of sources and their formats - a CMS with a clean interface is a different matter from twenty years of grown file storage.
  • The share of PDFs and how structured they are. A PDF with an outline is processable; a scanned one needs OCR first.
  • Whether versioning already exists in the CMS or has to be established first.
  • The number of audiences and languages, because each means its own view of the same corpus.
  • Connection through a CMS interface or only through the sitemap - the former is more stable and cheaper to operate.
  • Operating model: with us, with you, or handover after acceptance.

Limits

What the navigator is not

A guided navigator is deliberately narrower than a chatbot. That narrowness is exactly why you can point it at public expert knowledge.

  • Not a replacement for your support

    It takes the always-identical paths off your desk and hands over the rest cleanly. Anyone who needs a real answer reaches a human faster - not less often.
  • Not an open-ended chatbot

    Topics outside the corpus are declined rather than answered creatively. That is what separates it from a generic website bot.
  • No advice on individual cases

    It shows what your sources say and who is responsible. Assessing a concrete case stays with you.
  • No search across protected documents

    The navigator works on released content. For internal stores with permissions, the internal assistant is the right build - it enforces permissions before retrieval. See the internal assistant →

Page count alone does not justify a navigator. What matters is whether the corpus is versioned, whether different audiences need different parts of it, and what a wrong answer costs. Three hundred heavily versioned guidelines are a case for it; two thousand flat pages often are not, and there a good search is cheaper.

Where we stand: the navigator is currently being built in a pilot project on a large medical knowledge corpus. We will publish figures and results once the project is finished and cleared.

What clients say about working with us

From a knowledge base with an AI assistant and local AI integration to data sovereignty and ongoing operations.

AI Platform

We were looking for a secure yet easy-to-use alternative to the large American providers and came across WZ-IT. WZ-IT advised us on choosing the right models and implemented the integration for us. Beforehand, we were able to try everything out calmly on a test instance. Today WZ-IT runs Open WebUI for us on our own domain, with a convenient Microsoft login and open-source models hosted by a German provider. Our team can now work productively with AI without resorting to external tools or shadow AI. Working together is straightforward, and questions are answered quickly and clearly. With WZ-IT we also have a partner at our side for further AI projects. (translated)

Knowledge Management & AI

The knowledge from many years in the solar industry lived in the head of our former managing director, and it still lives in the heads of our employees today. We wanted to secure it, not as a folder full of notes, but in a way that lets us ask questions in daily work and get reliable answers. WZ-IT advised us from the start and weighed different approaches and knowledge management systems against each other with us before we decided. What was built is a custom knowledge base with an AI assistant that brings together conversations, notes, documentation and manuals: from the platform through onboarding our team to support in operation. Conversations are transcribed and facts are extracted; we review and correct everything ourselves before it is stored, because we do not want to trust an AI blindly. The system runs in our own environment, and the data stays with us. What surprised us was how efficient it was: WZ-IT used existing open-source software and extended it specifically for our requirements, instead of selling an expensive custom build from scratch, as is often usual with IT service providers. Timo and Robin understood our actual problem, preserving knowledge during the generational handover, and implemented it step by step: from the proof of concept through setup and validation with our own data to productive operation, explaining everything clearly along the way. Next, we want to extend this to the knowledge of our employees, so that this does not depend on individual people either.
