Remote sessions: work continues when you're away
One of the biggest advantages of web Cowork is that remote sessions keep running even after you close your browser or shut down your computer.
How remote sessions work
- You describe a task to web Cowork.
- Claude starts work on Anthropic's servers.
- You can close your browser, go offline, or sleep.
- The session continues running and completes the work.
- When you return to claude.ai, you see the results and history.
This is ideal for long-running tasks that would otherwise require keeping your computer awake.
