Your company's second brain

It takes two: you and Duet

Duet reads your email, meetings, Slack and docs, and remembers what the company owes, decided and knows, so you can think while it remembers. Every answer cites its source; everyone sees only what they already could.

Two players, one company

You

Decide, promise, ask

You do the work that needs judgment: you talk to customers, make the calls and change your mind when the facts change.

Duet

Read, remember, cite

Duet reads everything you connect, keeps every promise, decision and fact with its source, and answers you or your agents in seconds.

From scattered messages to one memory

1
Connect your sources
Gmail, Calendar, Drive, Slack, Notion and meeting notes. Read-only; each person connects their own.
2
Duet keeps the record
Every promise, decision and fact it reads becomes a record with its owner, date and the message it came from.
3
Ask it anything
In Duet, in Slack or from Claude, ChatGPT and Cursor. Answers cite their sources and respect who may see what.

What Duet remembers

Every commitment

Who owes what to whom, by when, and whether it happened, found in the mail, meetings and threads where it was made.

Every decision, with its why

What was decided, who decided it, the alternatives it closed and the message or document that shows it.

Permissions respected

You see only what your own sources already let you see. So does every agent that asks Duet as you.

Your AI tools ask Duet, as you

Duet is an MCP server. Claude, ChatGPT, Cursor or any MCP client signs in as you, reads only what you can, and every call is logged where you can see it.
