Office AI agents: Cowork, ChatGPT Work, and more
By Philipp Kant 5 min read
Office AI agents are assistants that do the work instead of only answering: they read your inbox, calendar, and files, operate programs in the browser, and deliver finished documents. Since summer 2026, such agents ship inside the subscriptions of Anthropic, OpenAI, and Perplexity. October and November 2026 brought the next steps, and the question for companies is no longer whether, but for what.
As of November 9, 2026, from the vendors’ announcements and the coverage around them. Features and plans change monthly.
What changed in autumn 2026
| Date | Vendor | What is new |
|---|---|---|
| July 9, 2026 | OpenAI | ChatGPT Work: an agent across connected apps such as email, Slack, Google Drive, and CRM, with scheduled tasks |
| October 21, 2026 | Anthropic | Claude Duet as a preview: an agent that reaches out on its own and asks before sending, paying, signing, or deleting |
| Late October 2026 | Anthropic | Cowork merges into the regular Claude chat; for Enterprise the combined view becomes the default on November 16 |
| November 4, 2026 | Perplexity | Teammates: long-running agents, reachable in Slack, in the Max plan at 200 US dollars a month |
The direction is the same everywhere: away from the chat window, toward an agent that stays on a task for hours and delivers results. Duet is aimed explicitly at professionals and small businesses.
What an office agent does today
- Inbox and calendar: sorting mail, drafting replies, scheduling meetings, through connectors to Outlook or Gmail.
- Documents: reports, spreadsheets, and slides built from connected files.
- Programs in the browser: operating web applications such as accounting or a ticket system, through a browser extension.
- Recurring tasks: running at fixed times, for example sorting the inbox every morning.
How such an agent works step by step, and when it hands over to a person, is shown in the live demo on our home page.
Where office agents still fail
The marketing shows the successful run. Three data points from the last few weeks show the rest:
- Multi-step professional work: in Surge AI’s DAYJOB: Tax benchmark (October 27, 2026), agents worked on 50 real tax assignments with 1,789 client files. The best, Claude Sonnet 5.5, passed 10.8 percent. The failures were judgment errors, not arithmetic.
- Reliability: “For anything multi-step, it feels like a roll of the dice whether it completes the task right or quietly breaks on step three,” one user wrote in r/AI_Agents (October 2026).
- Cost: according to the KPMG Global AI Pulse (Q2 2026), 49 percent of surveyed leaders delayed or scaled back an agent once its costs outgrew its value.
An office agent is strong where a person looks at the result anyway: a draft, a summary, a proposal. It is weak where it writes, unsupervised, into a system that does not forgive a mistake.
Subscription agent or agent in ERP, PIM, and CRM
| Office agent (subscription) | Agent in your systems | |
|---|---|---|
| Works for | one person | one workflow in the company |
| Access | that person’s accounts | the ERP, PIM, and CRM interfaces, with its own permissions |
| Approvals | asks the user | rules per workflow, approval by the responsible role |
| Log | chat history | every step with its source, reportable |
| Cost | subscription per seat | one-time build, running cost per task |
The two do not exclude each other. The office agent helps one person with email and documents. A workflow like entering orders from email, which runs dozens of times a day and writes into the ERP, needs an agent with fixed rules, permissions, and a log. The difference is also explained in What is an AI agent?.
Data protection: which plan for company data
Sending emails with customer data through an agent requires a data processing agreement (DPA) with the vendor. At Anthropic it applies through the commercial terms for Team, Enterprise, and the API, not for the consumer plans Pro and Max. Claude Duet launched only for Pro and Max in the US, so it is not yet an option for company data in the EU. Check for every vendor which plan the DPA covers before the first real task runs through it.
How many companies already use agents
A YouGov survey for the German retail association bevh and Alibaba.com among 438 decision makers (September 2026) found that 24 percent use AI agents, and about 45 percent of companies with ten or more employees. The biggest obstacles are lack of trust (32 percent) and unclear value (31 percent). A subscription solves neither; a first workflow with a number before and after does. How to choose it is covered in 10 questions before your first AI agent project.
FAQ
What is Claude Cowork? Cowork is the working mode of Claude in which the agent completes tasks on its own with files, connectors, and programs. Since late October 2026 it is part of the regular Claude chat rather than a separate view.
Is ChatGPT Work the same as Claude Cowork? Both are agents that finish tasks across connected apps, with scheduled tasks. They differ in their connectors, their plans, and how usage is billed.
Does an office agent replace a custom-built agent? For personal work, often yes. For workflows that write into the ERP or PIM and need approvals, permissions, and a log, no. There an agent works through the systems’ interfaces, as described in MCP or API.
How do I start? With a workflow that happens often and whose mistakes are cheap, such as pre-sorting the inbox. How an agent classifies a real email is shown in the free AI Inbox Triage.
