How it works
It reads once, writes down what it learned, and never guesses at read time.
A search box spends its effort when you ask. Nemosyne spends it when a document arrives, so what comes back is a typed fact with a citation — not a ranked list of passages to read yourself.

And it keeps listening
One document, close up
What it keeps from one page of minutes.
When a document like these minutes arrives, Nemosyne reads it once and keeps what it says, each item citing the passage it came from.
Investment Committee
Minutes of the sitting of 12 March
Item 2 — Meridian Holdings
Meridian1 reports ARR of €12.4m for FY20252. Its top two customers account for 31% of revenue, and the committee named customer concentration3 as its principal concern.
The Committee approved the investment, on condition of a second customer above 10% by Q34.
- Entity Meridian Holdings, a company. Your CRM calls it Meridian Holdings Ltd; Nemosyne resolves both names to one company, so every document that names it either way meets in one place.
- Fact ARR: €12.4m, FY2025. Kept as a figure with its period, citing this passage.
- Memory The committee’s principal concern, kept in the minutes’ own words and citing them.
- Memory The condition of approval, kept in the committee’s own words, with its deadline.
Many documents, one picture
Every document adds to one connected picture.
As documents arrive, Nemosyne connects the companies, people, decisions and concerns they name, and keeps what was said about each in the source’s own words.

Across your systems
Each system holds a fragment. Nemosyne holds the company.
One company shows up as a folder in one system, an account in another, an org in your CRM and a model on somebody’s drive — under four slightly different names. None of those systems knows the others exist. Nemosyne reads all of them and resolves them into one company, with the people, the deals and the numbers attached to it.
What each system holds
- SharePoint /Deals/Meridian Holdings/ — 28 files calls it “MERIDIAN HOLDINGS LIMITED”
- Salesforce Account & open opportunity calls it “Meridian Holdings Ltd”
- Affinity Org, owner J. Rivera calls it “Meridian”
- Google Drive meridian-model-v7.xlsx calls it “meridian-model-v7”

What no single document says
Written down as a note of its own, citing every document it drew on.
Some things are in no single document. Nemosyne looks for several of them on a regular sweep and writes each down as its own note; others your team can ask for.
The same concern, again
When the same concern turns up in several separate documents within a period your practice sets, Nemosyne writes that down as its own cited note.
Customer concentration at Meridian, raised in the CIM, a lender’s letter and the CFO’s email within three months. 3 documents
How a concern is framed
When a concern recurs, Nemosyne also keeps how each document describes it, in that document’s own terms.
“Top two at 31%” in the model; “one anchor client” on a management call. model v7 · call notes
A case that looks like an earlier one
Ask “have we seen this before?” and Nemosyne shows earlier decisions whose recorded reasoning reads like this one, labelled as resemblance, never advice, and cited.
Falcon, declined in 2024, turned on the same concentration. falcon §8.1
Where the record disagrees
Where two sources disagree on a number, Nemosyne keeps both, cited, says which it settled on and why, and lists the open disagreements in one place.
The certificate says €14.2m, the audited accounts €11.9m: both kept, each cited, with the reason one leads. certificate · accounts
A date that passed
When a date your documents set passes and no later document restates it, Nemosyne notes it, with the due date and the day it checked.
The Q3 covenant test on the €60m facility, due 15 September; no later document restates it. Checked 22 September. facility · sched. 9
What you expected, next to what happened
Ask how a forecast turned out and Nemosyne pairs it with the reported figure: same company, same year, same currency. It never says the decision was wrong.
The base case at approval said €8.0m revenue; the accounts say €7.1m. ic memo · FY accounts
Each note states what the documents say and which documents say it. It does not judge severity, and it does not recommend. Which kinds apply depends on your practice’s vocabulary.
Take it with you
Works with the AI you already use.
Connect Nemosyne to Claude, ChatGPT, your internal copilots or your own agents. The memory goes where you work — and your AI stops being a brilliant stranger.
See the disagreement, not the average
When two documents state different values, both stand — each with the source that asserted it and the authority that source carries for that kind of fact. Your assistant is told the answer is contested rather than handed a blended number nobody wrote.
Reach the source in one step
Every fact cites the passage it came from, and each one can be opened. An answer that cites names the documents it drew on.

As your firm changes
Your firm’s memory isn’t frozen at setup.
As your team and its AI use Nemosyne, recurring questions and missing capabilities become signals. When the same need keeps appearing, Nemosyne can propose an addition to your firm’s vocabulary, memory or workflow — with the evidence that caused the proposal.
Nothing changes itself. An administrator sees what people were trying to do, why the memory as it stands could not do it, and exactly what would change. Your firm decides whether to adopt it. Learning from use is in preview.
Everything it knows was written down.
If you would rather have the boundary than the mechanism, read what we enforce — and what we do not do yet, in our own words.
