Claude Duet was introduced on 21 October 2026 as a research preview, initially by waitlist for US Pro and Max subscribers. Its inclusion in those plans does not mean it creates a second independent allowance: the announcement says it uses the same usage limits as the rest of Claude.
As checked on 30 October, the official announcement still describes a waitlisted research preview starting with US Pro and Max. It lists iOS, Android and claude.ai. This guide revisits that nine-day-old launch to plan shared usage; it does not announce a new access expansion today. If the feature is absent, confirm eligibility and the invitation rather than buying another plan on the assumption of extra capacity.
Plan the whole day’s work
Before handing it an ongoing task, check your actual access and current usage information. A waitlist entry is not activated access. Do not budget one full allowance for ordinary conversations and another for Duet simply because it has a separate app.
For example, if you want an overnight research brief and also need an interactive editing session, prioritize the work and decide what can wait. The interface and documented limits are better evidence than the number of app icons on your phone.
Check what actually finished
Read the brief and open its cited materials or saved result. If the task pauses, preserve its progress and inspect the stated reason before restarting. A pause is not automatically a reset failure, and a restart may consume more usage. The preview’s availability and behavior can change; recheck the current announcement and account rather than treating this dated launch as general access everywhere.
