Claude Duet
NexusAi Summary: Claude Duet is a proactive professional agent built on Claude Opus 5.5 that monitors connected apps, executes background multi-step workflows in a sandbox, and requests approval for consequential actions to reduce context switching for professionals.
NexusAi Overview
Work starts with a single ongoing thread: type or speak a task, and Duet runs the appropriate steps in the background. It consolidates context from connected apps, prepares drafts and action plans, and notifies you only when your review or a decision is required, reducing manual triage and context switching.
Core capabilities
Ideal users are professionals and small teams who juggle email, calendar, CRM, billing, and storefront tools—product managers, operators, consultants, and small-business owners who need continuous monitoring and multi-step automation without losing final control. Early testers used Duet to catch calendar mistakes, assemble client briefs on the go, reconcile invoices across locations, and automate repetitive marketing and support tasks, demonstrating measurable time savings for workflows spanning multiple systems.
- Delivers a concise morning brief of prioritized items across connected apps.
- Runs multi-step background workflows inside a sandboxed virtual machine for unattended tasks.
- Drafts messages and prepares documents, then waits for explicit user approval.
- Integrates with accounting, CRM, payroll, and commerce tools via Marketplace connectors.
- Uses a safety classifier and approval gates to protect strict-sensitive information.
Why it matters
Who it's for
To begin, sign in with a Claude account and join the Duet research preview on Pro or Max plans. Setup transfers your Claude memory and lets you grant tokenized connector access for selected apps; Duet requests the minimum permissions it needs. Configure notification cadence and approval preferences, and use the single-thread interface or voice to assign tasks. Documentation details connector permissions, sandbox behavior, safety classifiers, and steps for revoking access or auditing activity for teams and enterprises.

Claude Duet is a research-preview app that turns Claude into a proactive, judgment-driven assistant for professionals and small businesses. Running on Claude Opus 5.5, Duet uses a sandboxed virtual machine and browser to perform background checks, coordinate connectors, and assemble multi-step workflows without requiring a user’s device to remain active. It delivers a concise morning brief, watches calendars, email, billing, and storefronts, and drafts or prepares work while preserving user control: payments, signatures, and publishing require explicit approval. Credential handling uses tokenized flows and virtual cards to avoid exposing raw secrets, and a dedicated safety classifier plus an auto-mode approval layer guard against leaks and unintended actions. Duet emphasizes calibrated notifications, broad connector coverage, and enterprise-grade auditability during the research preview.
