What this site is

Cases are grouped by scenario: personal assistant, workflow, writing, research, data, and coding. Open a case, read the limits, and copy the prompt.

The same twenty-three pages are written in English, Traditional Chinese, Russian, and Japanese. Nineteen are workflow cases. Four research pages: one restates the public X profile of karan ahuja and two posts about Claude Duet, one maps Anthropic’s 2026-10-23 article on safety, privacy, and credentials, one restates public pages on Claude Duet as a personal always-on agent, including the free lead of Dan Shipper’s Every Vibe Check, and one maps the US Pro and Max waitlist, shared usage limits, and the one full limit reset available until 30 November 2026. The product names stay in Latin script.

The contact email for this site is hellovibecoder@proton.me.

Anthropic’s 2026-10-23 article on approvals, sensitive-information checks, and credentials is mapped on Claude Duet safety, privacy, and credentials. That page is an unofficial summary, not a security audit.

What Claude Duet is

Anthropic describes Claude Duet as a proactive agent you message by text or voice. It uses the memory, skills, and connectors already on your Claude account, and it keeps working on a cloud computer after you close the app.

Each morning it can brief you from email and calendar. Through the day it checks connected accounts every few hours, not continuously. Finished files such as a brief, a financial model, a deck, or a dashboard show up in the Make tab. The Tasks tab shows work that needs you. Only you can mark a task complete.

It can use connectors you connect yourself, including Gmail, Google Calendar, Google Drive, Slack, QuickBooks, HubSpot, Docusign, and Calendly. The launch post also names Gusto payroll, LinkedIn job posts, Canva campaigns, Shopify, and purchases through Link or Shop Pay. Slack has limits. Microsoft 365 is not available yet.

Named connectors, and which of them have a case on this site, are listed on the Claude Duet connectors page. Google Drive is named in the help center and has a case for finding a file and handing the result back.

How to get Claude Duet

  2. 2Open the Claude Duet product page and choose Join the waitlist. Use the email on your Claude account.
  3. 3Choose your plan and phone type, then submit. Invitations go out in waves and do not promise a date.

Claude Duet product page

Limits that apply to every case

During the research preview you cannot choose a model: Claude Duet runs on Claude Opus 5.5. You cannot watch its browser. It cannot see the files on your computer. Background checks count toward your plan limits. It is designed to ask before sending, paying, signing, or deleting, and some actions stay off limits even with approval, including trading securities and moving money between accounts. It can misread a thread. Review drafts before you confirm them.

What this batch does not claim

  • Named early users in the launch post — Jess Provencher, Amin Ebrahimi, and Mya Dalton — are Anthropic’s own tester stories. This site did not find independent public write-ups to add on top of that.
  • Gmail inbox triage and the morning brief, a Google Calendar page for events and open time, scheduling with Calendly, missed Slack messages, a QuickBooks page for connected books and drafts, QuickBooks and Stripe invoice reminders, HubSpot follow-ups, Docusign agreements, Gusto payroll, LinkedIn job posts, Canva campaigns, Shopify store setup, purchases through Link or Shop Pay, and finding a file in Google Drive are cases on this site.
  • A richer Shopify visual editor and 1Password sign-in are described as coming soon. They are not written up as available.
  • The scripted café dashboard on the product page is marketing. This site does not treat a 5:30 a.m. auto-refresh as a documented feature.
  • Category blurbs on the home page follow the scenarios Claude Duet is actually described as doing. They are narrower than a generic “review any pull request” coding guide, because that workflow is not in the Claude Duet sources.

FAQ

Is this an official Anthropic site?

No. duetcases.com is an unofficial community site. It is not affiliated with Anthropic, and it is not a way to contact Anthropic.

Where do the cases come from?

Each page cites a public source: the Claude Duet launch article, the help center article “Get started with Claude Duet,” the product page, or Anthropic’s 2026-10-23 safety article. The karan ahuja page cites public X posts. The personal-agent page also cites the free lead of Dan Shipper’s Every Vibe Check (2026-10-21) and Every’s Context Window (2026-10-25). Prompts on this site are community templates written to match those descriptions. They are not official Anthropic prompts.

Can anyone use Claude Duet today?

Not from this site. Anthropic says the research preview is a waitlist for Pro and Max subscribers in the US. Team and Enterprise plans are not included yet. Invitations go out in waves.

Will these prompts send email or spend money on their own?

The templates tell Claude Duet to wait. Anthropic says Claude Duet is designed to show you what it is about to do and wait before it sends a message, makes a payment, signs a document, or deletes anything. You still have to read the draft. It can be wrong.
