Cowork
Cowork is an autonomous AI agent built into the Claude Desktop application for macOS and Windows. Rather than answering questions in a chat interface, Cowork takes a goal from the user and works through it independently — reading and writing local files, moving between applications, and synthesizing information across multiple sources — then returns a finished deliverable. The user does not need to coordinate each step.
Cowork brings the agentic capabilities found in Claude Code to general knowledge work. It is designed for tasks like reorganizing file systems, assembling reports from scattered source documents, extracting and structuring data from PDFs or images, and running multi-step workflows across local tools. Users can follow along through progress indicators, steer the task mid-run, or assign work remotely via the Dispatch feature from the Claude mobile app.
Cowork launched as a research preview in January 2026 and is available to paid plan subscribers (Pro, Max, Team, and Enterprise). Team and Enterprise admins can enable or disable Cowork organization-wide from Organization settings. Conversation history and task data are stored locally on each user's device and are not captured in Anthropic's Compliance API at this time.
When you’d use it
- ◆File Organization and Cleanup — A user's Downloads folder has accumulated years of unnamed screenshots, duplicate PDFs, and outdated drafts. They point Cowork at the folder and ask it to rename files based on content, deduplicate assets, sort by type and date, and archive old items into labeled subfolders — without touching anything manually.
- ◆Report Assembly from Multiple Sources — A consultant has 40 PDFs, meeting notes, and raw data CSVs spread across a project folder. They ask Cowork to read the entire set, synthesize the key findings, and produce a formatted Word document with an executive summary, section headers, and source citations — handling the assembly so the user only needs to review and refine.
- ◆Receipt and Invoice Data Extraction — A finance team member has 30 scanned receipt images and unstructured invoice PDFs. Cowork uses OCR to extract vendor name, date, amount, and tax from each file, populates a structured Excel spreadsheet with category totals, and moves the processed source files into an Archive subfolder.
- ◆Financial Reconciliation and Anomaly Flagging — A controller has bank statement PDFs and a committed expenses spreadsheet. They ask Cowork to cross-reference every transaction against the budget, flag items over a threshold that lack a matching budgeted line, and produce a reconciliation report with conditional formatting — ready for CFO review without manual row-by-row checking.
- ◆Remote Background Workflows via Dispatch — An analyst sets up a recurring task in Cowork and uses Dispatch to trigger it from their phone while away from the desk. Cowork runs on the local machine, processes new files that arrived overnight, and sends a completion notification so the analyst returns to finished work rather than a queue.
