Claude Duet's waitlist is now clear. On November 13, 2026, Karan Ahuja, Anthropic's product lead for Claude Duet, announced that every US Pro, Max and Ultra subscriber who was on the waitlist as of November 12 has now been invited. The Claude Duet research preview opened on October 21, and this is the first time it has opened to all eligible paying users in the US — anyone who has been waiting for over three weeks can start using it right away.
What this round of invitations covers
Duet is not a mode inside a chat window but a standalone app: it proactively goes through your email, calendar and invoices, hands you a morning brief first thing, pauses to ask before any important action that needs your confirmation, and keeps working in the background the rest of the time. This round covers all three paid tiers — Pro, Max and Ultra — with Ultra added on November 13 as part of an update to the product page and help docs. Newly invited users also get usage-limit resets: three on Pro and one each on Max and Ultra, and any unused reset expires on December 15. The Free plan and Team and Enterprise plans are still out of scope, and users outside the US still have to wait; Ahuja said only that more countries would open 'very soon', with no specific date.
Who still has to wait, and what to do next
US users already on the list who have not received an invitation yet should first check that the email they left on the waitlist matches their Claude account email — invitations only go to that address. US Pro, Max or Ultra users who have not joined the waitlist yet will still have to queue: Anthropic sends invitations in waves and has promised no specific waiting time. Duet is still a research preview running on Claude Opus 5.5, and its features and limit rules may keep changing; for anyone handing their inbox and calendar to an AI, the real test only starts once the invitation arrives.
