The answer, and where it came from.
edda reads the documents your company already has, answers questions in the tool your team already uses, and names the source behind every sentence. Document, page, revision. If it cannot find a source, it says so instead of guessing.
An answer nobody can check gets checked anyway.
A maintenance engineer asks an assistant for the torque on a flange connection. A number comes back, immediately, in full sentences, with the calm tone of a system that is sure of itself. They pick up the wrench, pause, and ask the hall: does anyone know if that is right?
From that moment the project is in trouble. Not because the number is wrong, it usually is not. Because the system raised a question it did not answer: where from. The engineer walks to the folder, looks it up, finds the same number, and has taken twice as long as without the assistant. The third time, they go straight to the folder.
The rollback is quiet. Usage drops over a few weeks until a figure appears in a review that nobody has to argue with, and someone says the team was not ready. What was not carried was the burden of proof, and it was sitting with the user.
Three commitments, built in rather than promised.
The citation itself
Document, page, section, revision date. Not “according to the maintenance manual”, but the exact place someone can open in ten seconds and read for themselves. Every answer, including the short ones.
Permissions from the source
What a person may not see does not appear in their answer, not even as a summary. Rights are read live from the source systems rather than copied into a second list that drifts out of date within a quarter.
Silence when there is nothing
No source, no answer. “I do not know” is uncomfortable in a demo and it is the reason the system is still running six months later, when the plausible-sounding alternative would have been caught out once and abandoned.
Three questions for any vendor, including us.
Ask something you already know the answer to
Then ask for the source. You are checking whether the citation is real and specific, or a plausible-looking reference to a document that does not contain the claim.
Ask something only one department may answer
Use the account of someone who does not have that access. If the answer appears anyway, the permission model is decorative.
Ask something your company has never documented
This is the one that decides it. A system that produces something plausible here will produce something plausibly wrong in production, and nobody will notice until a line stops or an auditor asks.

Questions
How is this different from Microsoft Copilot or ChatGPT Enterprise?
Both are good at general work and weak at your estate. edda is built around the sourcing requirement above: it indexes your specific systems, enforces your specific permissions, and refuses rather than improvises. Several of our clients run Copilot alongside it for drafting and email, and edda for anything where being wrong has a cost.
Does it work with German documents and English questions?
Yes, in both directions. The citation always points at the original document in its original language, so the person checking sees the real source rather than a translation of it.
What does it need from our IT team?
Read access to the systems in scope and someone who can answer questions about how the estate is organised. For a two-week pilot that is typically two or three hours of their time in total.
Where does the data sit?
Germany by default, elsewhere in the EU or the UK on request, or entirely on your own infrastructure. Source documents are never used to train models that other clients touch.
What happens after the pilot?
You get the number and the method. If you continue, the rollout goes department by department rather than company-wide, because adoption fails in different ways in different teams and it is cheaper to learn that on one of them.
See it against your own documents.
A demo on our data tells you very little. Bring three questions from your own operation and we will show you what the answers and the citations look like.
