A Practical Course
Claude Cowork for Desk Work
Learn what Cowork actually does well, where it fails, and how to use it on the tasks you do every week.
Reconciliation. Triage. Reporting. Briefs. Compliance prep.
What this course teaches
- Set up Cowork with the right permissions and folder access
- Write structured prompts that produce usable Excel, Word, and PowerPoint files
- Recognize hallucinated data, broken formulas, and misclassified output before sharing it
- Connect Cowork to Jira, Slack, OneDrive, and Outlook for live data
- Build role-specific workflows for chargebacks, support, sales, compliance, or finance
- Set up recurring automations — and know when they're worth the effort
This course does not teach AI theory, prompt engineering tricks, or how to "10x your productivity." It teaches you how to use one specific tool for one specific kind of work: structured, repetitive desk tasks where the input is messy and the output needs to be organized.
This course is for you if...
- You spend hours on structured, repetitive tasks: reconciliation, triage, formatting, reporting
- You work in operations, support, sales, compliance, finance, or admin
- You are not a developer and don't want to write code
- You want to understand what AI automation can and cannot do before committing
This is probably not for you if...
- You need guaranteed accuracy without human review
- You work with raw PCI data or unredacted PII
- You want fully autonomous automation with no oversight
- You expect polished output that doesn't need checking

Where it breaks
Cowork is a research preview. These are current realities, not edge cases.
Outbound communication
Cowork can draft emails, Slack messages, and reports. It should never send them without your review. One wrong email to a merchant or regulator is worse than no email.
Math and formulas
LLMs do not calculate — they predict what numbers look right. Cowork will produce formulas in Excel, but the formulas may reference wrong cells or miss edge cases. Always verify independently.
Compliance and audit
Anthropic explicitly states that Cowork activity is not captured in audit logs or compliance APIs. Use it for first-draft preparation, not final decisions on KYC, AML, or chargeback rulings.
Security: prompt injection
Prompt injection via uploaded documents is a demonstrated attack vector (PromptArmor, January 2026; "Claudy Day," March 2026). Treat any external document as potentially containing hidden instructions.
The Course
6 modules. Each is 45 minutes with hands-on exercises using practice data packs. Every module ends with copy-paste prompts you can use immediately.

Producing Excel, Word, and PowerPoint from Raw Data
Turn CSVs and notes into formatted business documents
Connecting Cowork to Your Tools
Jira, Slack, Confluence, HubSpot — live data instead of CSV exports
Building Workflows for Your Role
A complete automation sprint for your department
Scheduling Recurring Tasks and Measuring Results
Automations that run on a schedule. Honest ROI tracking.
What you need before starting
Pro is about £18/month. Max is £80–160/month. Cowork consumes significantly more tokens than regular chat — heavy users on Pro report hitting limits within days. Max is more practical for daily use.
Mac is more stable as of March 2026. Windows support launched February 2026 and users report more friction.
Never grant Cowork access to Desktop, Documents, Downloads, or your home folder. Smaller scope means smaller blast radius.
Each module is a self-contained session with hands-on exercises. You can do one per day or one per week.
No coding knowledge required. No terminal. No developer tools. You write plain-English prompts and work with files.
How the course works
- Each module is 45 minutes with hands-on exercises using practice data packs (CSVs, text files, exports)
- Exercises have role-specific variants: chargebacks, sales, support, compliance, finance, operations
- Every module ends with copy-paste prompts you can use on your real work immediately
- Every workflow includes failure modes and a review checklist — so you know what to check
Frequently Asked Questions
Do I need to know how to code?
No. The entire course uses Cowork's desktop interface. You write plain-English prompts and work with files (CSV, Excel, Word, PowerPoint). No terminal, no scripts, no developer tools.
Will this work on Windows?
Yes, but with caveats. Windows support launched February 2026 and is less stable than Mac. Users report API connection failures and NAT range conflicts. The course works on both platforms, but expect more friction on Windows.
How much does Cowork cost?
Claude Pro is about £18/month. Max is £80–160/month. Cowork consumes significantly more tokens than regular chat. Heavy users on Pro report hitting limits within days. Max is more practical for daily use.
Is my data safe?
Cowork runs in a sandboxed VM and only accesses the folder you grant. However, prompt injection via uploaded documents is a demonstrated attack vector (PromptArmor, January 2026; "Claudy Day," March 2026). The course covers security practices in every module. This is a research preview — Anthropic's privacy practices are still evolving.
How much time will I actually save?
It depends on the task. Settlement reconciliation (30-60 min manually) can be generated in 2-3 minutes but requires 5-10 min of review. Some workflows save 20+ minutes per run. Others save nothing once you account for prompt iteration and error checking. The course teaches you to measure before you claim.
Can I take just the modules relevant to my role?
Modules 1 and 2 are prerequisites for everyone (setup and verification skills). After that, jump to whichever modules match your work. Module 5 has role-specific tracks for chargebacks, sales, support, compliance, finance, and operations.
My company already uses Glean / Copilot — do I still need this?
Yes. Enterprise AI platforms are great at searching your company's knowledge and answering questions. This course teaches you to BUILD things — Excel reports, Word documents, scheduled automations. Different tools, different jobs.
Start with Module 1
45 minutes. By the end, you'll have Cowork set up, completed a settlement reconciliation from two CSV files, and learned the prompting framework you'll use for the rest of the course.
No prerequisites. No code. Just a Claude Pro or Max subscription and an empty folder on your computer.
