The whole team's memory, skills and accounts, in every AI they use
One memory for the team, skills for its daily work, and its Gmail, calendar and Slack, inside Claude, ChatGPT and Cursor.

The deal context from sales, the launch plan from marketing, the decision from Tuesday's meeting: written down once, available to everyone's AI, including the new hire. Plain files the team owns, not a black box.
Gmail, the calendar, the web. Connect one for the whole team, and GBrain holds the sign-in and hands an AI the result of a call, never the password. Each AI gets a permission level, and every action lands on one record. Keep a personal account out of it with a second workspace of your own.
Gmail, Outlook, Stripe and many more are on the list. Not on it? Add an MCP server on the web by its address; the official MCP registry lists more than 10,000.
Pick a skill, answer a couple of questions, and GBrain takes that part of the week: the time-consuming jobs and the tedious ones, run every morning or just once. Read what came back, and get on with the bigger thing.
How the business is doing, and where you're dropping the ball. One email a day, from whatever you're paid through, your own product, and the team's mail, calendar and code.
