Anthropic is opening a research preview of Claude Duet, a proactive agent app that runs on Opus 5.5 and asks for your approval before sensitive actions. Access starts by waitlist for US Pro and Max subscribers, according to Anthropic.

Duet updated a 12-slide deck with Q3 data, pulled 25 of 26 documents into a data room, and drafted answers to expected questions from Harbor Ventures partners before their Thursday 10 a.m. meeting.
Duet built Marlo Pulse, which pulls data from point-of-sale systems, Shopify, CRM, support inbox, payroll, and bank accounts.
