Follow-ups, coordination, reminders, tasks bouncing across chats. By the time you look up, the day is gone and the important work never got touched.

The problem
Your day runs you
You run the company, but operations run your calendar. Sound familiar:
Nothing is written down where it can be found
Decisions live in your head, in voice notes, and in scattered docs. Every time someone asks "what did we agree on?", you lose twenty minutes reconstructing it.
Delegating to AI feels risky
You are not going to let a bot email your clients unsupervised. Rightly so. The problem is not AI: it is the missing human approval gate.
How it works
From zero to operating in 24 hours
No migrations, no training sessions, no new software to learn. Your channel is WhatsApp.
Cortex learns your world
One 15-minute interview: your team, your clients, your priorities, how you make decisions. That seeds your private brain.
Your first briefing arrives
The next morning, before your first coffee: today's agenda, the hot items, and one single priority. Forty seconds to read.
You delegate, approve, it executes
You text it on WhatsApp like you would your chief of staff. Cortex proposes, you approve with one tap, it executes and reports back.
The system
Three pieces. One system.
Not a chatbot. An agent that executes, a memory you own, and a cockpit where you stay in command.
Agent
Always on · WhatsApp firstWorks while you sleep. Prepares briefings, drafts, follows up, and flags issues before they become fires.
- Daily briefing at 6:30 AM
- Executes work, not just replies
- Reports everything it does
Brain
Your second brain · SovereignEvery decision, contact, and agreement is written into a knowledge base you own. Export it anytime.
- Your data, your property
- Exportable in open formats
- Connects via MCP to Claude, ChatGPT, and Notion
OS
Your cockpit · Full controlA web app where you see everything the agent does and approve every external action with one tap. Nothing ships without your OK.
- One-tap approvals
- Tasks, agenda, and follow-ups in one place
- Full audit trail of every action
Your data lives in your brain
Not in someone else's model. Your knowledge is yours, and it leaves with you whenever you want.
Human approval on every external action
No email, message, or change goes out into the world without your tap of approval.
Zero payments executed by the agent
Cortex never moves money. It can prepare, remind, and alert; paying is always human.

FAQ
What every executive asks before joining
What happens to my data?
It lives in your private brain, a knowledge base isolated per customer. It is never used to train third-party models and never shared. You decide what goes in and what comes out.
Can I export my brain?
Yes, it is yours. Export the whole thing in open formats anytime. It also connects via MCP to Claude, ChatGPT, or Notion, so your knowledge works outside Cortex too.
What does Cortex NOT do?
It never executes payments. It never sends external emails or messages without your approval. It does not decide for you: it proposes, you decide, it executes.
Which apps does it connect to?
Today: Google (Gmail and Calendar), WhatsApp, and Notion. On the roadmap: monday and Asana. If your critical tool is missing, tell us in the form; the first 20 members shape the roadmap.
What are Cortex Credits?
They cover the AI model usage behind your agent. Every plan includes a generous monthly allowance. Run out and you can top up, or connect your own API keys (BYOK) and pay only the subscription.
