Capabilities
What Anthropic says Duet can do during the research preview.
- Sends a morning brief across email, calendar, and connected apps, and can start first steps such as drafting replies. [2]
- Monitors connected apps through the day and messages you when something needs you; follows up on threads that have gone quiet. [2]
- Handles admin tasks such as scheduling meetings, unpaid invoices in QuickBooks or Stripe, payroll in Gusto, and agreements through Docusign after you approve. [1]
- Builds dashboards, forecasts, prototypes, and web apps; buys through Stripe Link or Shop Pay after approval. [1] Uses its cloud browser for sites with no connector. [2]
Strengths
Where Anthropic's published design stands out against the other tools on this page.
- Most explicit hard never list for money: no trades, no transfers between accounts, and no access to someone else's account, even with your approval. [2]
- Dedicated classifier and safety prompt for the strictest tier of sensitive information, with health and finance details only on your explicit instruction. [1]
- CLAIM · Largest stated connector catalogue: 6,000+. [1]
- REPORTED · Every called it the first personal agent they would call a pro tool, with strong channels and task list, but said email drafts are worse than Dot's. [3]
Connectors
Apps and services Duet can use.
- Uses connectors you already set up in Claude, such as Gmail, Google Calendar, Google Drive, Slack, QuickBooks, HubSpot, Docusign, and Calendly. [2]
- Supports plugins, including a small business plugin. [2]
- Partner services: Stripe, Link, and Shop Pay. Link and Shop Pay are Duet-only for now. Slack works with limits. Microsoft 365 is not available yet. [2]
Approval and safety
When Duet must stop and show you the action first.
- Before it sends a message, makes a payment, signs a document, or deletes anything, it shows you exactly what it will do and waits for approval. [1]
- If you cannot approve right away, it finishes the rest of the task and brings the approval back later. [2]
- Actions are checked by Anthropic's auto mode classifier. [1]
- Link asks you to approve the spend. [1] Each purchase uses a one-time card. [2]
Proactive behaviour
When Duet reaches out without a fresh prompt from you.
Memory
What carries over between sessions.
Limits
Hard stops Anthropic documents.
- Won't trade securities, move money between accounts, or access someone else's account, even with your approval. [2]
- Doesn't make phone calls or text other people. Can read your Claude work but can't change it. Can't show its browser. [2]
- Personal errands, such as booking tickets, are weaker. Bigger tasks use more of your plan limits. [1]
Privacy
How credentials and sensitive data are handled.
- Never directly sees your passwords or sign-in tokens, following the Claude Managed Agents design. [1]
- When a site asks for a password, you type it into a separate form on your device, and the form sends it straight to the browser. [2]
- Tested by red teams and an external penetration-test firm, and covered by the public bug bounty. [1]
- Whether Duet data is used for training is not described on these pages. [2]
