Anthropic’s Claude Chrome Extension Automates Browser Workflows
Anthropic released a Chrome extension that embeds its Claude model as a sidebar inside the browser, enabling the model to read pages, click buttons, fill forms, navigate tabs, and run tasks on a schedule. The newsletter documents real-world uses including an autonomous negotiation that yielded a $100 AT&T billing credit, scheduled recurring workflows, Gmail and calendar triage, and reorganizing 900 Google Drive files. Claude can read grouped tabs for multi-site competitive intelligence and produce structured outputs or full spreadsheets when paired with Cowork.Build. A developer integration allows Claude Code to write in the terminal while the extension tests in the browser. The author highlights practical limitations for large, data-heavy jobs and recommends breaking workflows into subtasks; four prompt templates for safe automation are included.
Embedding an LLM as an interactive, schedulable browser agent enables practical automation (customer service, inbox/drive cleanup, multi-tab intel) and developer workflows, which can change how teams automate web tasks and extract cross-site data — relevant to MarTech automation and data collection, though not a platform-level policy change.

Anthropic’s Claude Cowork Automates Office Workflows
Anthropic released a Chrome extension that embeds Claude as a sidebar inside the Chrome browser, enabling the model to read pages, click buttons, fill forms, navigate tabs, and run scheduled automations. The extension turns recorded workflows into recurring tasks and can operate across multiple logged-in sessions and tabs, enabling use cases such as negotiating a $100 billing credit with AT&T autonomously, organizing 900 Google Drive files, inbox triage, and multi-tab competitive intelligence that can produce structured spreadsheets when paired with Cowork.Build. Developer workflows are supported via integration with Claude Code so agents can write in terminals while the extension tests in the browser. The author notes real-world limitations—particularly for data-heavy tasks that should be split into subtasks—and includes prompts and safety checks for building automations. This follows Anthropic product updates (Cowork features, plugins, scheduled tasks and browser automation) and demonstrates agentic browser automation moving from demo to deployed workflows.
Anthropic rolls out Claude Cowork on Web and Mobile
Anthropic has begun rolling out Claude Cowork for web and mobile, enabling its agent-mode to continue working in the background and across devices. Users can start a task on a laptop, let the Claude agent run timed or long-running workflows (research, briefings, email drafts, meeting follow-ups) and later retrieve results on a smartphone. The beta will first be available to Max subscription customers, with other plans to follow. Anthropic also extended doubled Cowork usage limits through August 5 to support larger delegated tasks. Projects, documents and Live Artifacts remain synchronized across devices and Claude will only execute actions with user approval.
Anthropic launches Claude Cowork for non-technical tasks
This LastWeekIn.ai podcast episode (recorded 2026-01-16, hosted by Andrey Kurenkov and Jeremie Harris) covers Anthropic’s new Cowork desktop agent and broader AI industry moves. Anthropic’s Cowork — a desktop agentic tool tied to Claude Code — was discussed alongside reports that Anthropic is raising $10 billion at a $350 billion valuation. The episode also reviews large funding rounds (xAI reportedly raising $20 billion), OpenAI’s compute deals, and infrastructure strains: NVIDIA faces supply bottlenecks for H200 chips driven by strong demand from China. Policy debates over U.S. export controls and their industry implications featured contributions referencing Alibaba leader Justin Lin and Jake Sullivan (former national security advisor). The episode mixes product news, major funding announcements, research items (including Deep Delta Learning), and infrastructure and policy developments affecting the AI ecosystem.
