Join the waitlist

Built for professionals who multiply their impact with AI.

Why you need one

Draft an email in one line

Without the brain: you paste the thread and explain who Marie is. With it: “reply to Marie” and it already knows her role, your history, the project state, and your voice.

Walk into every meeting prepped

It knows who you are seeing, what you agreed last time, and what is still open. The brief writes itself from your own record, not from LinkedIn.

Never drop a promise

Commitments made in meetings and email are captured as they happen. Ask “what do I owe people this week” and get a real answer.

Write your weekly update in two minutes

It happened in your meetings and mail, so the brain already has it. The update is a draft to edit, not a memory exercise.

Delegate recurring work to AI for real

Your way of doing a task is written down as a procedure, so an assistant runs it your way instead of a generic way.

Make a decision with your own history behind it

“What did we decide about pricing and why” returns your reasoning from ten months ago, not a fresh guess.

Intro two people without homework

It knows both, what they care about, and the last time you spoke. The intro drafts itself with real context.

Onboard a new tool or assistant in one connection

New AI, same brain. Zero re-explaining, day one.

Why a second brain, when Claude and ChatGPT already have memory?

Privacy

Pick what you want Claude and ChatGPT to see, and what you don’t.

Portability

Your memory is not locked inside one company. Change tools and it comes with you.

Accuracy

Easily spot and correct inaccuracies.

Action-oriented

Built to support actual use cases for business professionals.

How it works: auto‑capture and organize

Your workmail · meetings · documentsYour second brainpeople · projects · decisionsClaude · ChatGPTact with your context
  1. Connect your email, calendar, meeting notes, and Claude and ChatGPT transcripts.
  2. It organizes everything automatically into people, companies, projects, and the rest.
  3. It augments what it hears with external sources.
  4. You review it in the brain’s own browser, or right where you are: a person’s profile appears on their LinkedIn page.
  5. You flag what is private.
  6. Connect your brain to ChatGPT and Claude, and show only what you want.

It is yours

Take everything out whenever you want, in an open format, without a subscription to unlock your own words.

It is not tied to one AI company. Change tools next year and your memory comes with you.

It is not tied to your employer either. You will change jobs. This does not stay behind.

We do not train models on your memory. Your memory is private.

What would you want it to do?
