The situation
The problem addressed, the context, the people involved and the known constraints.
Cortex · Experience memory for your AI tools Your AI tools can change.
Your AI tools can change.
Your experience stays.
Cortex helps you pick up the thread.
Cortex follows the conversations you entrust to it, keeps track of decisions, open questions and useful learnings, then returns the right context where you work.
You control what is kept, transmitted and reused.
Beta · Windows x64
Beyond history
A history keeps messages. Cortex keeps the experience that can serve again.
A history can be re-read. A file can be found again.
But resuming work requires something else: knowing what had been understood, why a decision was made, what has changed since and what remains to be resolved.
Cortex maintains that trajectory across your sessions, subjects, tools and its integrated agent.
A trajectory, not a copy of the chat
Each step remains understandable later.
The open questions
What remains uncertain, contradictory or blocked, so a conclusion is not reused too quickly.
The decisions
The conclusion retained, the elements supporting it and the options set aside.
The outcomes
What actually happened after the decision and what that experience allows to revisit.
At the next resume, Cortex does not return the whole history. It prepares only the useful context, with sources.
In your usual tools
Your usual tools receive context at the right moment.
Cortex supports the tools you already use: Claude Code, Codex, Kimi Code, OpenClaw, Hermes, Antigravity, Cursor and web conversations captured by the Chrome extension.

Cortex inside your tools · on your machine Workspace · Product Subject · Contractor access
An organisation that follows the work
Cortex organises without asking you to classify everything.
The Workspace defines the boundary of your environment: a company, a product, a client or an activity.
Inside it, Cortex links sessions to existing Subjects, keeps general memory when no subject fits, and waits for your choice when the attachment deserves review.
- create a Subject
- explicitly choose where to attach a piece of work
- rename
- move
- correct Cortex
Customisation remains possible. It is no longer required for it to work.

Finding context again
Your tools can retrieve the useful memory.
Cortex can return context into the tool when you resume, or let a compatible tool consult memory read-only.
Context at the right time
Decisions, blockers and open questions return when you need them.
Tool search
A compatible tool can search memory without changing it.
Visible trace
You see what was transmitted or consulted.
Cortex distinguishes what was handed to a tool from what that tool actually did with it.
You stay in control
Cortex automates simple cases and brings sensitive decisions back to you.
A learning can be proposed without being used right away.
You choose the control level: validate everything, let routine cases pass, or limit requests to sensitive points.
Cortex notably checks
whether the information is sensitivewhether it contradicts an active elementwhere the information comes fromwhether it truly helps the current workwhether it must wait for your decision
The past does not become an eternal rule
What is no longer true does not keep deciding.
Information may have been correct six months ago and no longer be so today. An experience may be useful in one team and inapplicable in another. A conclusion may be reinforced, limited, challenged or revoked.

Revision
What is no longer valid can lose its influence without being erased.
Cortex preserves the history without automatically granting every old piece of information the right to influence the present.
Sessions, subjects and general memory
One conversation can feed several subjects without being lost.
You choose the conversations Cortex follows. You can pause them, decline them, attach them later or stop them.
When a general discussion shifts toward a project, each part joins the right subject or general memory.
Without forcing you to file everything by hand.

Cortex Agent
The Cortex Agent works with the same memory.
You can ask Cortex to resume a subject, explain a decision or prepare an action. Writes and commands follow the approval level you chose.

Each conversation keeps its settings: memory used, services opened, voice and action level.
Your environment stays yours
Your experience stays visible and revisable.
Cortex keeps its memory on your machine. Recognisable secrets are masked before being memorised, transmitted or returned to tools.
AI processing uses the connections you choose. The cockpit shows what is kept, proposed, corrected, revoked or transmitted.

A view of links between subjects, knowledge, sessions and sources to understand where a decision comes from.

A space to observe what Cortex understands and transmits, without changing your memory.
Editions
A local version for one machine, and a self-hosted version for organisations.
Your experience, at work for your AI tools
Cortex learns from real work without rewriting history.
Cortex links objectives, decisions, outcomes, corrections and open questions. A revoked element keeps its history, but no longer influences what follows.
The goal is simple: resume work with its history, sources, uncertainties and possible next step.
