People spend a long time trying to tell AI how they write. Warm but direct. Concise. Not stiff. It's hard to describe your own voice, and the description never quite lands.
You don't have to describe it. You've already shown it. Your sent folder is thousands of examples of exactly how you write, to clients, to your team, to partners. It's the richest sample of your voice that exists, and it's sitting right there.
So instead of explaining your tone, hand over the evidence. Pull a handful of emails you'd be happy to have written again. A client update, a tough message you got right, a note that sounded like you on a good day. Give those to AI and ask it to write the next one in the same voice.
The difference is immediate. Described tone comes back generic, because an adjective leaves too much room. Shown tone comes back close, because the pattern is already in the examples. Your sentence length, your openings, the way you soften a hard ask, the words you reach for and the ones you never use. None of that survives a description. All of it survives a sample.
A few things to keep in mind. Use your own sent mail, not someone else's. Keep anything client-confidential out of a personal account. And read what comes back, because close is not the same as right, and your name is still the one on it.
This is the smallest possible version of a real idea. AI gets good at your work when you give it your work. You don't start by explaining yourself. You start by showing it what good already looked like, and you have a folder full of that.
