In this episode of Business Brain, we get into when to stop using chat and move to Cowork. Chat is a great place to start — it’s just not where we should live. Dave’s signals: more than five back-and-forths, or constantly pasting in screenshots, log files, and PDFs. That’s the tell. Point Cowork at the folder instead and stop copying and pasting. His trick is to ask the chat directly whether it’s time to move, and to have it write the handoff prompt for the Cowork session, since Cowork doesn’t inherit the full context. Flip the default: assume you’re going to Cowork, then convince yourself why you should stay in chat. We also untangle chats vs. projects vs. Cowork vs. Claude Code — and the one real reason to stay put, which is cloud sync across devices.

Then Dave walks us through a wild experiment: handing $10K of found money to Claude to run as a 90-day trading portfolio. He planned it in chat with Fable, executed in Cowork with Opus, and let it pick platforms with API and MCP access — Kraken for crypto, Alpaca for securities. It insisted on a seven-day paper trading run first, keys live in a 1Password vault instead of the session, and there’s a kill switch on his phone. No options, so the floor is zero. Whatever happens, it’s tuition. Real story: Claude didn’t earn the money — it just got him far enough through the process to actually collect it. Get out of the chat, and keep living that Charmed Life.
