So here's the thing - Claude's desktop app has three modes, but most designers I talk to only ever use Chat. Which is fine! But you're leaving a lot on the table. Let me walk you through what each mode actually does, when to use which, and (honestly) when to just stick with Chat.

The 30-second version

• Chat = Quick back-and-forth. Questions, brainstorming, drafts. What you're used to.
• Cowork = Hand off a task and walk away. It works with your files directly.
• Code = Build software. Works in the desktop app, VS Code, or terminal. For when you're ready to prototype.

All three use the same Claude brain. The difference is what Claude can access and do.

Which One Should I Use?

Don't overthink this. Here's the decision tree:

<aside> 🎯

Are you asking a quick question or having a conversation?

→ Use Chat

Do you need Claude to work with files on your computer?

(Organize folders, create real Excel/PowerPoint, process multiple documents)

→ Use Cowork

Are you building something with code?

(Prototypes, components, working in a codebase)

→ Use Code

Still not sure? Honestly, just start with Chat. You can always level up later - there's no wrong door here.

🤯 10 Things you didn't know you could do

Okay before I bore you with the technical stuff, let me show you what actually gets designers excited. These are the "wait, it can do THAT?" moments.

With Chat (Free)

• 1. Screenshot any app and ask "what's wrong with this UI?"
• 2. Voice-ramble your way to a spec
• 3. Generate user personas from real data (not made-up ones)

With Cowork ($20/mo Pro)

• 4. Batch-analyze 10 user interviews in one session
• 5. Turn a messy Miro board export into a structured spec
• 6. Create a presentation from scattered notes across multiple files
• 7. Competitive audit with actual web research
