The era of half-cracking a laptop to keep AI agents running comes to a close. On Tuesday, Anthropic announced that Claude Cowork, its AI agent designed to perform digital tasks for you, is expanding beyond the desktop app.

You don’t need to leave your device active, aka laptop cracked open, to keep the agent going and run scheduled tasks overnight. Anthropic also announced limited versions of Cowork for users to interact with via its existing Claude smartphone app or the web browser, sans the formerly required desktop connection.

In the launch video for this feature, Anthropic shows someone asking for help with a business deal renewal scheduled for the following day. In a single prompt, the user asks Cowork to pull together data from email threads, Slack channels, meeting transcripts, and recent online chatter. Then the user asks Cowork to use that info to generate a reference document for the meeting and a prewritten email. Cowork could previously do all of that while your desktop session was active, at least. Now, the agent can run even after you clock out, catching those late-night incoming messages.

The agent wasn’t perfect, and it still exposed me to the risk of prompt injections or other security breaches, yet Cowork felt like a step change in how everyday users could interact with their devices.

This isn’t the first time Claude users have been able to interact with Anthropic’s agents on their mobile devices. Previously, users could pair their smartphone app with their desktop through the “Dispatch” feature. This enabled users to send task requests from their phone, no matter where they were. But this approach ...
