A personal operating system

Your working life, in working order.

Tasks, notes, meetings, and the people behind them — one fast, private workspace. With an AI layer that briefs you in the morning, writes up your meetings, and remembers what you agreed to.

01 — The system TASKS · NOTES · MEETINGS · PEOPLE

One system, not seven apps.

Your to-do list doesn't know about your meetings. Your notes don't know about your projects. Cortex keeps it all in one place — so everything you capture makes everything else more useful.

01

Tasks

Inbox, today, upcoming, someday — and a logbook that closes the loop. Capture in two keystrokes, triage when you choose to.

02

Daily notes

A page for every day. What you wrote, what you decided, what happened — anchored to the date it happened on.

03

Meetings

Synced from your calendar, recorded on your Mac, transcribed and summarized before you reach your desk.

04

People

Every stakeholder with their history attached: meetings shared, promises made, threads still open.

05

Projects

Tasks, notes, meetings, and people, gathered around the work they belong to. One page tells you where it stands.

06

Search

Keyword plus semantic, across everything you have ever put in. Ask for the idea, not the exact words.

02 — Meetings RECORD · TRANSCRIBE · SUMMARIZE

Walk out of the meeting with the notes already written.

Cortex records on your Mac, transcribes with speaker names, and turns an hour of talking into something you can act on.

a
Native capture One click in the menu bar records system audio and your mic — no bot joining your call.
b
Speakers, named Diarized transcripts mapped to the actual people in the room — not "Speaker 2".
c
Decisions and action items Summaries that separate what was decided from what was said. Action items flow straight into your inbox.
d
Coaching, if you want it Private feedback on how you ran the room: talk time, questions asked, commitments made.

Johannes
We still need an owner for the rollout. I can take staging, but production needs someone closer to infra.

Klaudia
I'll own production. Let's gate it on the budget review though — that has to land first.

What did Klaudia and I actually agree on for the rollout?
Cortex

Klaudia owns the production rollout and you cover staging — agreed in Tuesday's platform standup. It's gated on the Q3 budget review, which is still open and assigned to you, due today.

MCP server — works with Claude and any MCP client

AI that knows your context, not the internet's.

Everything you capture becomes context. The AI layer reads from your meetings, tasks, notes, and people — and answers with receipts.

a
Morning and weekly briefings What's scheduled, what's due, what's slipping — composed from your actual data before you sit down.
b
Meeting prep Walk in knowing what you discussed last time, what's still open, and what you promised.
c
An MCP server built in Connect Claude — or any MCP client — to your workspace. Your assistant finally knows what you're working on.
d
Your own keys Bring your own API keys. You choose the models; usage stays on your accounts.
04 — Ownership SELF-HOSTED · PER-USER ISOLATION

Private by construction, not by policy.

I Invite-only

Cortex is in private beta for a small group of people. No waitlist theater — just a door.

II Your infrastructure

Runs on your own server, against your own Postgres. Your working life never becomes a data point.

III Isolated by construction

Every query is scoped to its owner — isolation enforced in the data layer, not promised in a policy.

IV Signed and notarized

A native macOS app, Apple-notarized, with signed automatic updates. No Electron shell around a website.

Bring your work to order.

Cortex is in private beta. If you have an invite, sign in and the download is yours.
