What Duet does
Duet runs in its own app and connects to services such as work email, a calendar, Google Docs, and Slack. It presents suggestions as cards that a person can accept or dismiss. In testing, Duet linked a staff meeting summary sent by email with a direct message in Slack and identified a manager through a shared document used for weekly meetings.
The agent opened each morning with a short message and highlights for the day. It reminded the tester to pack an item for a video shoot before a flight and proposed tasks including drafting messages or adding notes to an agenda. Duet also spotted a scheduling conflict that left only a few working days before a large draft deadline. It proposed a plan, offered to update a shared Google Doc, and drafted a Slack message to flag the change. The draft mirrored the tester's lowercase style and used a team abbreviation, but it shortened "signature" to "sig," a word the tester does not use. Slack labeled the message as sent with Claude.
