Conjuring digital companions: How I'm thinking better through AI

This last weekend I created another LLM-powered tool, Impersonaid (all puns intended). It’s a docs user simulator: you provide the URL of a document (or its Markdown source), select the virtual persona, and start a conversation about the content. Right after I released it, I realized that I had been talking to an imaginary friend to create more fictional interlocutors to interact with. It’s not as bad as it sounds, though. In fact, I would argue this is what writers are meant to do.
