Last issue was about using AI to build — a website, a newsletter, a brand from scratch in a weekend.
This issue is about the next layer: using AI to write. Specifically, to write in your voice — not the generic output that makes every brand sound like a press release with line breaks. The brief concept carries over. But a build brief and a voice brief are different things. Here's the second one.
AI copy is generic because the input is generic.
Most people use AI like a search engine. Type a request, get an answer, wonder why it sounds like everyone else. Then they edit it into something usable and tell themselves the AI is "pretty good."
The problem is not the model. It's the input.
AI doesn't know you. It knows everything about everyone. The brief is the filter that narrows "everyone's voice" down to yours. Without it, you're asking a stranger to write as you — and being surprised when it doesn't land.
Write this for your account. Paste it before every AI content request. That's the system.
Four lines. Written once. Works every session after that.
Every AI session starts cold. No memory of your last post, your tone, or what you've told it before. The brief makes every session start warm.
It works because specificity is compression. "Avoid hype words" is vague. "Avoid: game-changer, revolutionary, mind-blowing, unlock your potential" is instruction. The model can act on instruction. It can't act on vague.
Four lines of context cuts revision time in half. V1 is usually close enough to ship.
"Here are 5 amazing AI tools that will revolutionize your workflow and boost your productivity to the next level!"
"5 tools. One workflow. No noise. Here's what's actually working."
One of those gets saved. One gets scrolled past. You already know which.
Most people write a brief once, get better output, iterate a few times — and then throw it away. They re-explain themselves next session. And the one after that.
The brief is reusable. Save it. Name it by account or platform. It's the asset — the thing that makes every session start from the right place instead of from scratch.
This is the exact system we're automating. Write the brief once — and the tool handles everything after that.
V4 prompt, with brief: shipped
It's the brief.
Write your brief this week. Four lines. Name the file. The next time you open AI to write a caption, paste it first — and notice how much less editing you do after.
See you next Tuesday.
