Is Claude Duet just scheduled Cowork?
This is the most common question about Claude Duet vs Cowork, and it is fair. Cowork already has scheduled tasks that run in the cloud, so you can set up a daily summary of your inbox today. The difference is in three places.
Who starts the work
A Cowork scheduled task does the exact job you wrote, at the time you chose. Claude Duet decides for itself whether anything is worth your attention. If nothing changed, it stays quiet; if a contract renewal is suddenly due, it raises it without being told to look for renewals.
Where it runs
Duet always works on its own private cloud computer, and logins and approvals happen there too. Claude Cowork can also work with files on your computer through the desktop app, which Duet cannot.
How it reaches you
Duet is phone-first: push notifications, one continuous thread, voice input. Cowork results land in the Claude app when the task is done, and you go and look.
Where Claude Duet beats Cowork
Phone-first
If most of your day is away from a desk, Duet fits better. You approve a drafted reply from a notification and move on. The iPhone and Android apps are built for that.
Laptop can be closed
Duet's watching never depends on your machine being awake. It keeps checking your apps every few hours wherever you are.
Things you did not think to ask about
The launch demo's best moment is Duet noticing that a health permit had not been filed for a new location opening in 26 days. That is not a task anyone would schedule. Proactive noticing is the whole point, and it is why the morning brief matters.
Where Cowork beats Claude Duet
Local files
Claude Cowork can work with folders on your computer through Claude Desktop. Duet runs only in the cloud and has no local mode.
Team plans
Cowork is available on Team and Enterprise. Duet is limited to personal US Pro and Max accounts during the preview. If Claude is a work tool provided by your company, Cowork is the agent you can actually use today.
Long desk sessions
For a long piece of work you want to steer closely, such as a research report, a spreadsheet model or a slide deck, Cowork in the Claude app is the better fit. You can pick the model, watch progress and iterate in one sitting.
Which one should you open first?
A quick way to choose is to look at the shape of the job rather than the size of it.
| If the job is… | Reach for | Why |
|---|---|---|
| Ongoing and unpredictable (inbox, invoices, renewals) | Duet | It decides when something is worth raising |
| Fixed and recurring (Monday report, weekly digest) | Cowork scheduled task | Same output, same time, no judgment needed |
| Big and one-off (research report, financial model, deck) | Cowork | You steer it closely in one sitting |
| Involves files on your laptop | Cowork | Duet has no access to local files |
| Needs a decision while you are out | Duet | Phone notification with approve or decline |
| For your employer on a Team plan | Cowork | Duet is personal Pro and Max only for now |
In practice the split becomes obvious after a week. People tend to keep one or two scheduled tasks for things they never want to change, hand the messy middle of their day to Duet, and open the Claude app when they sit down to make something substantial. If you find yourself writing very detailed instructions to Duet about exactly when and how to run a report, that is a sign the job belongs in a scheduled task instead. If a scheduled task keeps producing output you ignore, that is a sign Duet's judgment would serve you better.
Claude Duet vs Claude Code
Different jobs
Claude Code is Anthropic's coding agent for developers: it reads and edits code in a repository and runs commands. Duet is a personal agent for inbox, calendar and business apps. They do not overlap much. A developer might use Claude Code all day and Duet to keep on top of email between sessions.
Use Claude Duet and Cowork together
Because both agents share your Claude memory, skills and connectors, they work well as a pair.
Handoff patterns
- Duet notices, Cowork builds. Duet flags in the morning brief that quarterly numbers are due; you open Claude and have Cowork build the full report from your files.
- Cowork schedules the fixed jobs, Duet watches the rest. Keep the Monday KPI report as a Cowork scheduled task, and let Duet handle the unpredictable things.
- Watch usage. Both draw on the same plan limits, so heavy use of one leaves less for the other. See Claude Duet pricing.
