Like the rest of the world, I’ve embraced chatting to large language models (LLMs) as part of my professional and personal life. I rarely use their output directly, but they help me think and brainstorm, give me ideas, and force me to write out my own thoughts, clarifying and refining them in the process (much like writing articles like this one does, by the way). These thoughts-in-writing are important to me, and that’s why I keep a history of them on my own machine. A conversational diary, so to speak. And so should you.
