ChatGPT that knows your company, on your phone too.

ChatGPT in a browser or in your pocket holds no key, and it does not need one: the open area of your brain is markdown our server reads on purpose, so ChatGPT reaches it wherever you are. The encrypted area stays out of its reach, by design.

askedOn the train. A prospect asks if single sign-on is on the starter plan. Is it?
chatgpt, reading the pageNo. playbook/objections.md: single sign-on is on the team plan. Offer the two-week trial of it; that is the line that has closed this objection twice.
Who can read itChatGPT on the web or on a phone, signed in as you, and every other agent of a person the playbook folder is shared with.
the connection

A connector, and a sign-in you do once.

ChatGPT reaches MCP servers through connectors. The brain is one: give ChatGPT its address, sign in when it asks, and the connector follows your account to the web and to the phone app.

  1. Add the connector. In ChatGPT, open Settings, then Connectors, and add one with the brain's address: https://brain.instibrain.ai/mcp.
  2. Sign in once. ChatGPT opens the brain's sign-in. Approve it as yourself, and it reads the pages you may read.
  3. Ask from anywhere. The connector is on your account, so the phone app has it too. ChatGPT searches the brain and reads the page before it answers.

what it reaches

The open area, from anywhere. The encrypted area, never.

The line is drawn by the key, and ChatGPT's servers hold none.

The open area

Every page of an open brain shared with you. Our server holds it as markdown, which is exactly what lets a surface with no key read it.

Not the encrypted area

An encrypted-area page opens only on a device holding the folder's key, and ChatGPT runs on servers that hold none. No prompt changes that: there is nothing on its side to decrypt with.

The phone, the web, the same brain

The connector lives on your ChatGPT account, so the answer you get on the train is the answer your laptop gets.

Recorded in the cockpit

Each read and each write is made under the connector's own credential, so the cockpit's access log shows what ChatGPT read, and when.

before you add it

What to know before the connector goes in.

Can ChatGPT on my phone read our encrypted pages?
No, and nothing you type changes that. The key for an encrypted folder lives on admitted devices running the sync client; ChatGPT's servers are not among them.
Can ChatGPT write to the brain?
Yes, once you approve writing, which is a second approval after the sign-in. Each write is recorded under the connector's credential, and the tool reference lists the seven writing tools.
Does each person on the team connect their own?
Yes. Each person adds the connector and signs in as themselves, so ChatGPT reads for each of them only the folders shared with them.

The brain in your pocket, with the encrypted part left at home.

Connect once, from the web, and the phone app has it too.
