Long, long ago, back in October 2024, I spoke to you about the launch of of Claude 3.7 Sonnet, an AI capable of “using a computer just as a person would. This means it can move the cursor, click buttons, type text, and navigate through screens.” It was a true revolution that, in light of the latest announcement from its creator, Anthropic, has already become a nostalgic exercise in naivety. The reason is that the latest evolution of Claude Cowork has surpassed it. By far.
If 2024 was the year to learn how to chat with AI, 2026 seems poised to become the year when, definitively, we will begin to delegate our day-to-day task execution into the hands of AI. Amid a sea of voices beginning to herald the advent of SaaScalipisis, Anthropic has announced the launch of a new suite of plugins for Claude Cowork and its advanced financial integration, marking a new phase in the era of agentic collaborators. These agents are capable of autonomously utilizing our everyday marketing and sales tools.
Claude Cowork represents Anthropic’s AI commitment to an agentic working environment, designed not only for chatting but for autonomously executing tasks by integrating directly with your professional tools.
Unlike conventional chat interfaces, it operates through a desktop application that allows it to interact with local files and utilize an ecosystem of plugins (called the MCP protocol) to function within widely-used business applications, such as Slack, Notion, or HubSpot. In this way, Claude takes on the capabilities of a true team member, able to plan multi-step processes, perform complex financial analyses, and manage marketing or sales workflows without the user having to manually copy and paste information.
The primary difference in this version of Claude Cowork compared to its predecessors is its capacity for action. Thanks to the MCP protocol mentioned earlier (Model Context Protocol), Claude can access your most frequently used tools (third-party tools, as previously discussed) and work with them based on the data available in your work environment.
Thus, through the new desktop application, Claude can read and process files located in your local folders, connect to databases, and employ plugins to perform actions in day-to-day tools. In this manner, Claude’s AI can process a report in Excel, cross-reference it with sales data, and, autonomously, draft campaign proposals in Gmail.
Among the new plugins and connectors already available are:
Additionally, companies such as Salesforce’s Slack have also created add-ons for use by their clients. Naturally, these plugins currently have limited capabilities: they do not yet allow you to send an email from Gmail (if that is what you were thinking of), nor to create content directly in WordPress.
For example, in the case of Google Workspace, its functions are limited to tasks such as “finding key information in email threads,” “drafting a response to the supplier’s pricing proposal, delaying the deadline but accepting the quote,” or “finding a time when Sarah, James, and I are all available in Calendar this week and sending a 30-minute invitation with a Meet link.” Conversely, others feature broader capabilities, such as Docusign: “Create a contract from our Master Service Agreement template, complete the commercial details, and send it to the Legal department for review.”
Without a doubt, one of the most notable features is the integration with Excel and PowerPoint. The latter, PowerPoint, appears poised to be especially useful for quickly creating presentations that are coherent with the companies’ branding, as Claude can read and analyze data from an Excel sheet, for example, and inject those findings into presentations that respect the brand’s templates, colors, and corporate typefaces. However, integration of Claude with Excel and PowerPoint is currently only available in a preliminary research version for paid plans.
Furthermore, Anthropic has announced the release of advanced financial analysis tools, which further expand its capabilities in this area. As explained by Anthropic itself:
“Finance work is carried out across many different places. A memorandum draws information from a model, a model draws from data, and these are incorporated into a presentation. Claude can now switch between Excel and PowerPoint without losing context: it retrieves data, updates models, and generates deliverables as a seamless, continuous task. An equity analyst can ask Claude to analyze earnings, update a financial model, and create a summary presentation, all without changing tools. When input data changes, Claude automatically updates the rest of the workflow.”
Anthropic has also announced a library of predefined plugin templates created in partnership with “professionals from the respective fields, ensuring that workflows, terminology, and outcomes reflect how the work is actually performed.” The new plugins are organized into two major categories:
Anthropic has democratized access to the interface, but retains advanced features for its subscription plans:
