I generated a really good tone of voice guide for myself today. All it took was 5 months of constant writing.

The guide says things like: "frequent mid-thought corrections," "questions that hang in the air," "comfortable stating observations as facts." I couldn't have told you that was my style before I spent all this time exploring.

I will probably not even use it, however we've started using AI in a similar way in our accounting startup these last weeks, after a year of manual work to learn about our users. That’s a way more interesting use case.
