Review: Claude Duet, Anthropic's Always-On Personal Agent

Every tested Claude Duet, Anthropic's always-on personal agent launching today in research preview, and found it the first personal agent worth calling a pro tool. Duet runs on Opus 5.5 in its own iOS, Android and web app separate from Claude, splits recurring topics into channels, tracks what it is working on and what it needs from the user, and edits docs, slides, designs and dashboards in place. The reviewer still flags gaps: it can see but not direct Claude sessions on the computer, its email drafts trail OpenAI's Dot, scheduled runs cannot reach custom connectors, and there is no real voice mode yet, only transcription.
