What do you actually get?

Eleven questions, about five minutes, and a folder of files at the end. One is a brand voice guide a person can read. The rest are the same rules written in the exact formats that ChatGPT custom instructions, Claude project instructions, Gemini, Copilot, Cursor and the Vale style checker each read on their own.

The paste versions come in five lengths, one for every published limit we could find: 500 characters for Canva, 1,500 for ChatGPT on the free tier, 3,000 for Claude, 5,000 for ChatGPT on a paid tier, 8,000 for Perplexity projects and Microsoft 365 agents. None of them is a longer version cut short. Each is rendered to fit.

Why a file rather than a prompt?

Describing your voice in a conversation works until that conversation ends. The next one starts cold, and you cannot teach an assistant to remember. You can hand it the same short briefing every time, and this makes the briefing.

There is a second reason most people never hear. Attaching a file to a project does not make an assistant follow it. OpenAI's own model specification says attachments carry no authority by default and are treated as information rather than instructions, unless you delegate that authority in your own words. Your download includes the line that does it.

What will it not do?

It will not hide that you used AI. Nothing does, and anybody promising otherwise is selling something that does not exist. What it does is make the writing sound like you rather than like the default.

It is a first draft, and it says so on its face. It lists what you left unsettled instead of guessing, and it caps at fifteen binding rules, because compliance with a set of constraints falls from about ninety-six per cent to as low as twenty as those constraints stack from one to twenty.

Where do the answers go?

Your answers stay with you. The questions are answered in your browser, the files are built in your browser, and none of that is transmitted to us. There is no account and no email gate. Page views are counted separately, and the notice at the foot of the page turns that off in one click.
