AI knowledge assistant for document collections

Answers from your own documents. With the source attached.[1]

DocumentChat answers questions from your own document collection - collective labour agreements (cao's), schemes, policy, handbooks - and backs every answer with clickable references to document and page. Not general AI knowledge, but what your documents actually say.

How it fits together

A document assistant is more than a chat window.

What it does

Built for people who need to be able to trust the answer.

  • Answers with evidence

    Footnotes on every answer point to the exact document and the page. No loose claims: the source is always attached, one click away.

  • Guided intake

    The assistant recognises what you want - answering, summarising or comparing - and if in doubt asks one specific follow-up question first.

  • Comparison at any scale

    Two documents side by side, or the whole collection at once in a readable table. Useful for schemes that differ slightly from one document to the next.

  • Documents processed properly

    New documents are read, split and enriched automatically. Tables stay intact, with their heading and context attached.

  • Full administration

    Usage, cost, quality and access: all of it can be followed and steered centrally from admin screens. No black box.

  • Safe inside your own environment

    Runs entirely inside your own cloud environment, with sign-in through your organisation account and access per role.

Trust and administration

Enterprise-grade, from day one.

An assistant that works with internal documents has to do more than answer well. DocumentChat was built from the start on what an organisation requires: secure access, auditable usage and administration without a developer in the loop.

  • Sign-in with your own organisation account (single sign-on)
  • Access per role: you decide who may see and manage what
  • Personal data in log files is masked as far as possible
  • Usage and cost per period visible to administrators
  • Runs inside your own cloud environment, the AI models included

In practice

Hundreds of cao's, thousands of pages, one place to ask.

For a Dutch trade union, DocumentChat runs in production over a large collection of collective labour agreements. Staff find in seconds what used to take minutes or hours of searching through PDFs - and always see the source alongside, so the answer also holds up in a conversation with a member or an employer.
