See what your work says about you.
Coredence reads what you have already written, distils it into rules about how you actually work, and keeps every one of them pointed at the evidence it came from.

What it produces
One rule, and the reason it exists
The engine reads what you have already written and writes down what keeps being true. Every rule carries the moments it was drawn from, so you can disagree with it about something specific.
This one turns up in seventeen of eighteen subjects. It is not about a project — it is about a person.
“Reaches for a formula before a fixed number, even when the number would do”
Drawn from
- “let’s not hardcode 40 here, make it scale with the level”
- “replace the magic numbers with a curve we can tune”
- “why is this a constant? it should come out of the formula”
- Measured, not remembered
- Rules come out of evidence, not out of you telling it about yourself.
- Every claim has a source
- Open any rule and read the messages it was drawn from.
- Stays on your machine
- One SQLite file in your home directory. No account, no server.
What it measures
Five kinds of claim, kept apart
A preference and a value are not the same thing, and a passing mood is neither. Collapsing them is how a memory feature ends up telling your assistant that you dislike a library you complained about once, on a bad afternoon, two years ago.
Values
What you will not trade away, however inconvenient.
“Would rather cut the scope than lower the standard”
Patterns
What you do again and again, whether or not you would claim it.
“Finishes the main path before touching the polish”
Voice
How you say things — length, directness, what you refuse to pad.
“Says the uncomfortable version first and softens it after”
Preferences
What you reach for first when nothing forces your hand.
“Prefers the boring dependency maintained for a decade”
Current state
What is true this month and will not be true next year.
“Is deep in a launch and guarding the scope hard”
How it works
Download it, point it at your work, look
- 1
You point it at your work
Conversations, commits, the corrections you made when something was wrong. It asks before it connects anything, and nothing is sent anywhere — all of it is read on your own machine.
- 2
It distils rules, and holds back what it cannot support
Anything seen once is kept as a draft until it happens again. Two rules that contradict each other become a question for you, not a silent decision.
- 3
You look at the result
The whole identity as one picture. Every rule opens onto the evidence it came from, and you can hide it, merge it, or argue with it.
Why you can trust it
What it refuses to do
The engine would rather say less about you than say something it cannot defend. Most of what follows is a decision to stay quiet.
It will not keep a rule it has seen once.
One sighting is a coincidence. It waits.
It will not resolve a contradiction on its own.
Two rules that disagree become a question you answer.
It will not write a rule it cannot show you the reason for.
Every rule keeps its evidence or it does not exist.
It will not guess to fill a gap.
A thin identity is honest. A padded one is not.
It will not send anything anywhere.
There is nothing to send it to.
Where it lives
One file, on your machine
The identity is a SQLite database in your home directory. There is no account, no server and nothing to sign in to. You can copy it, back it up, open it with any SQLite browser, or delete it.
The app that draws the picture opens that file read-only. It cannot change what it shows you, and that is a property of the file handle rather than a policy.
You never have to take that on faith. While it is running, ask the operating system what it has open: the answer is one database and no network connections at all.
The first command should print nothing. The second prints your whole identity, in a tool nobody here wrote.
Where this is going
What ships today, and what does not
The whole point of the product is that it only says what it can support. The same applies to the page you are reading.
01
Shipping now
The engine and the macOS app: read your work, distil it, look at the result.
02
Being built
A connection to the assistants you already use, so a new conversation starts knowing how you work.
03
After that
Windows, and a view of how the identity changes over months rather than one snapshot.
Get it
One download, no terminal
The engine that reads your work ships inside the app. Nothing to clone, no Python to install, no command to run — open it and it asks what it may read.
macOS 14 or later · Apple silicon and Intel · Notarised by Apple
Open it
It asks which sources it may read, and connects nothing until you agree.
Leave it a couple of minutes
The first pass reads a few hundred events. After that it keeps up on its own, or waits until you ask.
Look
The whole identity as one picture, every rule opening onto the evidence behind it.
A Windows version is planned. An identity is one file and moves between machines with you.
Questions
Before you install anything
- Does anything leave my machine?
- No. The engine reads local files and writes a local database. There is no account and no server component — the app has nothing to talk to even if it wanted to.
- What exactly does it read?
- The sources you connect during setup, and only those — it asks first and connects nothing until you agree. While it runs you can check that it holds no network connections at all, with one command on the privacy page.
- Can I disagree with a rule?
- Yes, and that is the point of keeping the evidence. You can open a rule, read what produced it, and hide it, merge it, or answer the question the engine raised about it.
- Does it work with my AI assistant yet?
- Not yet. Today it shows you the identity; the connection to assistants is the next piece being built. What you can download reads and draws, nothing more.
- Is it macOS only?
- It is where we started, not where it stops — a Windows version is planned. The part that reads your work is already portable and an identity moves between machines as one file; it is the window that has to be rebuilt.
- What does it cost?
- Nothing has been decided. What exists today is free, and any future paid piece would be an addition rather than a wall around what you already have.
