What you settled, and should not have to settle again next time.

Remembering is not rereading.
When a conversation ends, not everything in it matters the same for what comes next. Finding what was said is not the same as remembering what matters today.
Cortex does not reread your old conversations. It keeps what matters for what comes next.
What you took back, refined or put straight along the way.
taken backWhat the work revealed, and will still hold in six months.
discoveredWhat cost you once, and is better not done twice.
to avoidWhat you tried then set aside — and does not need trying again.
set asideThe rest can be forgotten. What Cortex hands back to your agents is what still matters.
The memory cannot be hidden.
If a piece of information can influence your agents, you must be able to see it and correct it.
Where the work stands, without rereading it.
You come back to a project several days later. What was decided is there, what is blocking is stated, what needs your view is flagged. Nothing to reread.
What you keep apart stays apart.
What it keeps, what it learns, and where it comes from.
What you said does not get mixed with what Cortex inferred about the way you work. Every piece of information says where it comes from, and you can correct it, flag that it is no longer true, or remove it.
Information you remove stops influencing your agents.
A system that claims to remember without showing it is worthless.
Cortex tells you how many sessions it kept, what still contradicts itself, what is waiting for your view. Never an "all good" with nothing behind it.
If something is missing, Cortex says so and shows you what to do.
You keep the subscriptions you already have.
Your ChatGPT, your Claude Pro or Max, a coding plan. Cortex adds no subscription: it uses what you already pay for, and only says it is ready once it has checked.
Your credentials stay in your machine's vault.


You decide what it consumes.
Routine work, background work and hard calls do not need the same model. You choose which serves what, and what takes over if it fails.
If something stops answering, Cortex tells you instead of pretending.
You will not spend your days approving things.
Cortex works while you work. It comes to you when a decision genuinely deserves your attention, not for every piece of information.
What cannot be undone always requires a gesture from you.
The same context, where you work.
You switch tools or subjects. Decisions, reasons and open questions stay available.
Claude Code
context comes back inside the toolYou start in the morning, a decision is made. Nothing to do on your side: it is kept.
Codex
context comes back inside the toolIn the afternoon, you carry on elsewhere. The morning's decision is there, with nothing to explain again.
Your web conversations
sessions are keptChatGPT, Claude.ai, Gemini, Antigravity: what you choose to follow joins your memory. Cortex then helps you find it again from the cockpit or the Cortex Agent.
A session only enters Cortex if you allow it.
You choose the conversations Cortex uses, and you can go back on that decision. Nothing enters memory without your consent.
On a given conversation, you allow Cortex to follow it. Until you do, nothing is kept.
The conversation comes across as it goes. Nothing to copy, nothing to file.
The session is offered to you. You are the one who attaches it to a project, or sets it aside.
The gesture is identical for Claude Code and Codex. Your memory stays under your control, and you also choose which AI services Cortex uses to understand, consolidate and answer.
Picking work back up without starting over.
Without rereading
The decisions made, what is still blocking, what remains open. Without reopening the conversation.
Without explaining again
The project's context comes back to your agent when it needs it. You do not have to lay it out again.
Without repeating
Your ways of working, once confirmed, follow you from one project to the next. You can see them and correct them.
Cortex helps you work with your memory, without replacing your tools.
- Claude, Codex, ChatGPT or Gemini. You keep using them when they are the right tools.
- A manual note filing system. Cortex organises what it understands and lets you correct it.
- A notebook you have to file yourself.
- A memory that learns silently. You see, correct, revoke and limit what can be used.
- Experience memory for the AI conversations you choose to follow.
- A cockpit to see what is kept, what awaits your review and what goes back to your tools.
- A Cortex Agent that resumes a subject with the same memory, by text or voice.
- A control frame: you choose followed conversations and the approval level required.
Ask Cortex to resume a piece of work.
The Cortex Agent uses the same memory as the cockpit. It can explain a decision, prepare an action or retrieve open points, then ask your approval before writing or acting.
It is not a parallel memory: the cockpit and the agent read the same history.
Resume your subjects with their history.
Install Cortex, choose the conversations to follow and find decisions, sources and open questions when you need them.
