Two days of unread mail, from the terminal or from an AI running the same command.

What Command line does

Gmail and Calendar, as commands

Search mail, list the day, draft a reply. Each command is one action on a connected account, at the level that account allows.

One vocabulary for every account

List, search, read, write. A new account joins the same small set of verbs, so the email commands teach the calendar ones and the rest.

Connect once; the keys stay on GBrain

Connecting is a page in the browser and one command. The terminal holds a GBrain key; the Gmail and Calendar keys never leave the server.

What you get with Tools

Everything in Tools

The same tools in every AI that speaks MCP

One address, pasted once into ChatGPT, Claude, Claude Code or Cursor. Each gets the same accounts and rules.

See how it works

Passwords and API keys never reach the AI

Connected accounts are held by GBrain. An AI gets the result of a call, never the key.

See how it works

A permission level for every application an AI can reach

Gmail has four levels, Calendar two, web search is on or off. Set per application, for each AI.

See how it works

A circuit breaker on every tool, for when an AI goes haywire

Every tool on every account has a daily line. Cross it and that tool trips; nothing else does.

See how it works

A log of every action an AI takes with connected accounts

One row per action. Who asked, which AI, which account, what it did, whether it was allowed.

See how it works

Access that ends when you say, and on a date you pick

Turn an AI off and its next request is refused. Every AI's access also has an end date.
