Momor knowledge graph
Knowledge you can question.
Most AI remembers what was said. Momor’s work has to stand up to disagreement, change and audit, so we built a knowledge graph where every fact can answer for itself. Ask this one.

Two independent sources agree, so the fact is held strongly.
Why we built it
We didn’t set out to build a knowledge graph. Our work needed one.
A Momor workflow can wait days for a decision while the world moves underneath it. A supplier changes a date, a regulator changes a rule, two documents stop agreeing. Remembering what was said isn’t enough. The work has to know what changed, what depended on it, who said so, and how sure anyone can be.
So that’s what we built. Here are the questions we think anyone should ask of AI that remembers, and how Momor answers them.
Question 1
When two sources disagree, who wins?
The evidence does, not the date.
A newer statement doesn’t quietly replace an older one. Knowledge stays as it is until a supported correction changes it; a weaker contradiction stands beside it as an attributed claim. Momor weighs authority, evidence and what is at stake, then carries on, looks further, flags it, or asks a person.
Question 2
How sure is it?
As sure as its independent sources.
Every fact carries how strong its evidence is. Each independent source adds its own reliability, so stronger sources count for more and a page repeating another adds nothing. That also means one source can’t make something true by saying it in many places.

Question 3
Can it add things up?
Yes, because a fact knows its parts.
A fact is linked to who, with whom, what, when and how much. So a question that spans many documents becomes a walk through what is already known, and every number traces to where it was read.
Question 4
Is it still true?
It knows when it was true.
Readings have a window. A price goes stale; a company’s country doesn’t. Dates are stored as dates and put into words only when read, so “in two weeks” always means two weeks from today.

- Quote expiresSupplier quoteStored as 2026-10-31Read today as “4 days ago”
Question 5
What did the answer actually use?
It records the difference.
Reading a fact isn’t relying on it. Each answer names the facts it stood on, and only finished work adds what it learned, so you can check the facts that mattered.
- ReadLooked at while working. Reading alone changes nothing.9 facts
- Relied onWhat the answer stood on, each tagged with what it supplied: the amount, the date, who decided. Facts that are relied on rank higher next time.3 facts
- LearnedWritten once the work finished: the new toll, with its start date and sources.1 fact
Question 6
Where did it come from, exactly?
Back to the moment it was read.
Every source points into the record of the work that read it, kept by Durable Events. Open it and you see the page, file or message, and the step that read it.

Question 7
Who can see what?
Three graphs, kept apart.
What the organization knows, what is known about a person, and what one run has found are separate, and nothing is copied between them. Each run reads and writes only the graphs it is allowed to.
- World graphWhat the organization knows beyond any one person or run.Stays inside the organization.
- User graphWhat is known about one person: what they prefer, what they already know.Goes with that person to every organization they belong to. Never shown to any of them.
- Flow graphWhat one run has found.Kept with the run.
Not for sale
There’s no price for it. It comes with the work.
The knowledge graph isn’t a separate product to buy or wire up. It is how Momor knows things, in every product that needs to.
