How it works

Five steps,
over and over.

CORA watches how people use your product, fixes what gets in their way, and proves the fix worked. This page is the whole thing — nothing else is happening behind it.

Build something newWatch CORA work
01

It watches

Where customers hesitate, where they give up, how fast things load, where the system is exposed. You choose what it can see — turn anything off and it stops looking there.

Customer records, messages, anything you mark private: closed by default.
02

It spots the problem

It tells you what it found, why, and what fixing it should gain — in plain words you can disagree with. Being able to argue with it is the point.

03

It builds the fix

On a copy, away from your live product, tested against your rules. Fail a check and it goes no further.

04

You approve it

Nothing reaches customers until you say yes.

Just tell me

It finds and explains. You decide what gets built.

Build it and show me

It arrives finished. You press go.

Handle the small stuff

You name what it may ship alone.

Four things are never automatic: prices, policies, who can access what, and anything touching customer data.

05

It checks the result

The new version goes to a slice of real customers and is compared on the exact thing it was meant to improve. Win, and it stays. Lose, and it comes out — and CORA remembers why.

One exchange

All five steps, the way you’d see them.

The name

Continuous Observation,
Recursive Advancement.

It watches without stopping, and every improvement builds on the one before it. That combination — always watching, always building on itself — is what makes CORA an RSI Agent rather than another coding assistant. CORA is not sold on its own — it is the part of ZB Stack that makes your software improve.

Undo

Anything it does
can be undone.

One click and the previous version is back — every change, however long ago it shipped. What can’t be unsent — an email, a payment — CORA never touches alone; those sit with the four things that always wait for a person.

And every change is written down: found, built, approved, and what happened after. The whole history, readable by you and any engineer you hire.

A real one, about this website

Most improvements are small.
That’s the point.

What we saw
On five pages, the top image was told to load last. On slow connections, visitors saw a blank space first.
Why it happened
A “load later” setting — right further down a page, wrong for the first thing on screen. Copied onto every page built after it.
What we already knew
The largest image on the first screen should never wait. The kind of rule CORA carries from one system to the next.
What we changed
All five images now load immediately.
Who said yes
[SLOT: name] — 22 July 2026.
What happened
The image loads the moment the page does. We didn’t measure it against live traffic, so we won’t quote you a number.
Who found it
A person, during a review. Not CORA.

Every change to this site is recorded this way

Five pages shipped with the same mistake — not carelessness, just improvement waiting for a person with time. That is what CORA replaces. The next record here will be one it found itself.

what it needs next.
