If you are just getting started, pick one of the three systems (ChatGPT, Claude, or Gemini), pay the $20, and select the advanced model. The advice from my book still holds: invite AI to everything you do. Start using it for real work. Upload a document you’re actually working on. Give the AI a very complex task in the form of an RFP or SOP. Have a back-and-forth conversation and push it. This alone will teach you more than any guide. If you are already comfortable with chatbots, try the specific apps. NotebookLM is free and easy to use, which makes it a good starting place. If you want to go deeper, Anthropic offers the most powerful package in Claude Code, Claude Cowork (both accessible through Claude Desktop) as well as the specialized PowerPoint and Excel Plugins. Give them a try. Again, not as a demo, but with something you actually need done. Watch what it does. Steer it when it goes wrong. You aren’t prompting, you are (as I wrote in my last piece) managing.
