Everything I know about your work, in one place you can see.

It builds itself.

A notebook waits for you to write in it. I read what you already wrote. Connect your mail, your calendar and your LinkedIn network, and the people, companies, meetings and promises arrive on their own, already joined up. You never file anything.

What's in it.

People

Everyone you write to, meet or are connected with, and how warm each relationship is.

Companies

Where they work, who else you know there, what you last discussed.

Emails and meetings

Short records with their dates. The full message stays in your mailbox.

Promises and tasks

What you said you would do, for whom, by when.

Notes and files

Thoughts you capture and documents you add, filed under the right person or project.

Memories

Lasting things you tell me about yourself and how you work.

Projects and ventures

Each venture's people and work, kept apart from the others.

Everything is joined.

A person belongs to a company. An email belongs to a person. A promise comes from an email and points at a project. That is why I can answer “who do I know at Northwind?” or “what did I promise Sam?” in a second: I follow the lines; I don't search a pile.

You can see it.

Open the brain map in the app and your working life is on one screen. Filter it to people, companies, projects, notes or memories. Tap anything to see what it is joined to. Prefer a list? It is one tap away.

You can teach it, and correct it.

Tell me something once and I keep it as a memory, with its date. Tell me something newer and the newer one wins. When I think two things belong together I draw a dotted line and wait: nothing is joined, merged or changed until you say so.

Every answer shows where it came from.

Each thing I know carries its source and its date: the email, the meeting, the note. When something is more than a few weeks old I say so, and when two sources disagree I go with the newer one and tell you about the older.

Some things stay out. Some stay private.

Put an employer, a client or a word on your Never-read list and nothing that mentions it is read, stored or shown. Health, family and money are marked private: they stay off the map and out of answers until you ask for them. What I won't do

One brain, wherever you ask.

Ask in the Twoself app, ask inside Claude, or let your team of doubles work from it overnight. It is the same brain each time, and it belongs to you, not to the AI model. Your memory and your AI Meet the team

It's yours to take, and yours to erase.

Your brain is stored in Sydney. Export all of it whenever you like, as plain files any program can open: text you can read, spreadsheets, and complete records for moving to another tool. Delete your account and every connection is cut at once; after 30 days everything is erased.
