The written version of this session, with the commands and templates to copy.
This is session 1 of Computer Control and Cowork, and it is free. If you have only ever typed into Claude's Chat tab, you have been doing half the job by hand: pasting files in, copying answers out. Cowork is the tab built to close that gap. This session covers what it is, what it is good for, how to hand it a task without babysitting it, and where its job stops and your coding agent's starts.
Claude Desktop has three tabs: Chat, Cowork, and Code. Chat is for conversation, Code is for software development, and Cowork sits between them. Anthropic describes it as a tool that "completes tasks you can steer from anywhere," working "directly in folders and tools you choose" and running the task through to something you review.
The difference from Chat matters most. In Chat, Claude answers you but cannot touch your files. In Cowork, Claude has permission to read, edit, and create files in the folders you specify, and it carries a multi-step task through to a finished result instead of describing the steps back to you.
Cowork runs on web, desktop, and mobile (web and mobile in beta), plus the Claude in Chrome side panel. Local file access, the built-in browser, and computer use still need the Desktop app open on your machine, even for sessions that otherwise run in Anthropic's cloud.
Cowork is built for real, multi-step office work, not one-off questions. For a business: a recurring weekly or monthly status report from existing files, scheduled to run on its own; a budget reconciled against actuals, returned as a formatted Excel file with variances flagged; call notes turned into a sales pipeline summary; a competitive scan pulled from your files and the web.
The same shapes carry over for a nonprofit: a donation ledger reconciled against a bank export instead of a budget, donor call notes turned into a pipeline analysis instead of a sales one, a funder landscape scan instead of a competitive one, a grant or vendor contract reviewed against your own playbook.
Four things make a Cowork task land well. Scope the folder: point it at the specific files the job needs, not your whole drive. State the outcome, not the steps, Anthropic's own framing is "tell Claude what you need, not how." Describe what done looks like: a file, a format, a place to save it. And review before you trust it. Cowork shows its work as it goes, the files it opens, the choices it makes, and it runs in one of three modes: Manual (asks before each action), Auto (approves with checks), or Skip (no approval). Start in Manual until you know what it does with a task like yours.
Pick one folder and try this, in Manual mode:
"In the folder I've shared, reconcile this month's budget spreadsheet against the bank export. Flag any line where they differ by more than $50, and give me back a formatted Excel file with the variances highlighted."
Watch the steps as they happen. Read the result before you act on it.
Cowork is for documents, spreadsheets, research, and ops work. The Code tab is explicitly for software development. If the job is "build me a tool" or "fix this app," that is your coding agent's work, even though both can run unattended in the same desktop app. They hand off cleanly: a Cowork research task can produce the brief you feed your coding agent to build; a script your coding agent ships can become one more file Cowork works from later.
Only give Cowork the folder a task actually needs, Anthropic's own safety guidance recommends a dedicated working folder over broad access. Some sensitive apps, investment and trading platforms, cryptocurrency, are blocked by default when computer use is on, and its guidance discourages pointing it at financial accounts, legal documents, or medical information. The docs do not spell out a rule for customer or donor personal data specifically, so treat it the same way: check your own plan's terms and your organization's data policy before handing Cowork a file full of customer or donor records, and when in doubt, do not.
You can explain, in one sentence, what Cowork does that Chat cannot. You have run one real task in Manual mode, watched the steps, and reviewed the result before acting on it. And you know which jobs are Cowork's, documents, spreadsheets, research, and which ones you hand to your coding agent instead.
Template included: Get the one-page task brief (folder, outcome, done-when, review step) and a starter list of ten Cowork tasks split for business and nonprofit use. Find it in your member dashboard under Templates.
Short on time? Agentic Quarks will implement this end to end, wired into your stack, and hand you the keys.
If you have only used Claude's Chat tab, you have been doing half the job by hand, pasting files in, copying answers out. Cowork is the tab built to close that gap: it carries a task through to a finished result. Free, session one.

Pick one folder and try this in Manual mode: reconcile this month's budget against the bank export, and flag anything off by more than fifty dollars. Watch the steps as they happen, then read the result before you act on it.
Cowork is for documents, spreadsheets, research, and ops work. The Code tab is for software development, build me a tool, or fix this app. They hand off cleanly: a Cowork research task can become the brief your coding agent builds from.

You are done when you can explain, in one sentence, what Cowork does that Chat cannot. You ran one real task in Manual mode, watched the steps, and reviewed the result. Members get the task brief and ten starter tasks in the template vault.
Cowork closes the gap between asking for help and getting the work done, right in your own folders. You have run one real task and know when to reach for it instead of your coding agent. Session two goes further: computer-use tools like Grok Bot.
