INSIDE CHITRAGUPTA

One brain, a team,
and the last word.

Your mail, files, calendar and notes become memories — and a graph of the people and projects inside them — in a folder on your Mac you can open, copy or delete. A roster of agents reads from that one brain, so you explain a client once. Anything that would leave your machine stops at a card you can edit, until you press Confirm.

“One sentence here, in their own words, about the thing they stopped having to explain over again every single morning.”
CONNECT

Imagine what it knows
once everything is
connected.

It reads the apps you already use, speaks MCP to anything else, and runs on whichever model you bring. Nothing is wired to one vendor — including us.

THE ROSTER

A team, not a
chat box.

Each agent keeps its own tools, its own permissions and its own way of working — and every one of them reads the same brain. Tell one of them something and you have told all of them.

BEYOND THE CHAT

Most of it happens
while you are away

Not everything is a conversation. Some of it starts on a trigger, some of it needs a real browser because there is no API — and all of it needs a way back if something goes wrong.

Automations

Work that starts on a trigger,
not on a timer you babysit

When a message lands in Gmail ↓ And it is from someone you listed ↓ Then draft a reply — and wait
Interrupted runs resume where they stopped

The browser

When a site has no API,
it uses the site

shop.example.com Changes allowed
news.example.com Read only
Refused — placing an order is never a click. It becomes a card with the shop’s own total.
