A password manager built for AI

Every AI wants its own sign-in to Gmail, GitHub and the rest. Connect each account to GBrain once, and Claude, ChatGPT, Claude Code, Codex and a terminal use it without ever seeing a password.

Get Tools, $19 a month

Two-minute setup. Cancel any time.

Connect an account once, then plug it into every AI you use

Pick from Gmail, GitHub, Notion and many more. Claude Code, Codex and Cursor use them from the command line. Every AI gets a permission level on every application, an end date, and one press to turn it off, and a daily limit on every tool.

1. Connect an account once

Gmail, GitHub, Stripe and many more. GBrain holds every sign-in, so no AI ever sees a password.

A full command line, included

GBrain gives every app you connect a command line, including the ones that never had one. Script it, pipe it, or hand it to Claude Code and Codex, under the same permission levels as every other AI. It works with every app GBrain connects.

How paying for Tools works

Worth knowing before you start.

One price for one person

$19 a month, for every application and every AI you use. There is no second tier, and nothing costs more because you use it more.

Cancel from your Billing page

Manage billing, on your Billing page, opens Stripe, which holds the card and the invoices. Cancel there, and the AIs and terminals stop reaching the applications at the end of the period you paid for.

More questions

Connect your first application in two minutes

Get Tools, add Gmail or the calendar, and say whether an AI may read it or change it. Every AI you plug in can use it on its very next call, and you can change any of it, or take all of it back, whenever you want.
