Nothing. Once per person per day. You get the file as a download and as a copy by email.
A Markdown text file that briefs your AI completely: positioning with headline ideas, audience, goal, offers, tone with example lines, a color palette with hex values, typography, imagery, a homepage blueprint, the site structure, SEO starters and build instructions for the agent.
No. The file works with any AI, whether Claude, ChatGPT or Gemini, and with any website project. An AI Website Template gets the most out of it, because its built-in skills read the file on their own and skip the four interview rounds.
Your answers go to Claude from Anthropic once for the distilling, and we store you as a contact to send you the file. Details are in the privacy policy, unsubscribing takes one click.
About three minutes for the nine questions, then around fifteen seconds for the distilling. The file grows live while you answer.
Yes, it is your file. Markdown can be edited with any editor, and you can create a fresh version any day.

Reference
Not because it builds badly, but because it lacks the decisions that come before building. A Website DNA is the file that records those decisions before the first line exists.
Tell an AI “modern, clean, professional” and you get the average of every site ever described that way. It only becomes usable with a decision that rules something out: who the site is for, what it does not offer, and which action should stand at the end.
The sentence names the offer and the audience and fits on one line. It is the only part of the brief that later appears almost word for word on the site, usually as the subtitle in the opening. If it needs two clauses, the positioning is not finished.
Calls, appointments, enquiries, purchases or applications. Each of these leads to a different structure, a different first screen and a different button. Name all four and you get a site that does none of them well.
The boundary prevents the most common kind of error: an AI generously adds what is usual in your field. A tax practice then gets a page about legal advice it is not allowed to give.
Sober, warm, direct, playful, premium, down-to-earth, technical, personal, bold. More than three cancel each other out, and the file ends up describing every website. Two opposing words together are allowed, by the way, and often the most interesting choice.
Every AI reads Markdown without a detour, it opens in any editor, and it survives any change of tooling. You hand your AI the file and tell it to read it before building. After that every change is one sentence in chat instead of a fresh explanation from scratch.
Put the file next to the code and your AI finds it again in every later session. In the AI Website Templates that place is Knowledge/, and the built-in skills read it on their own.
We shortened the form several times. What is left are the details an AI would otherwise have to guess. Everything else it can decide itself, and for font sizes, spacing and the order of sections its decision is usually better than a specification.
The DNA describes what the website should be. It says nothing about whether the effort is worth it and who carries it. That stays a decision you make, and it comes easier once the file shows how much substance is actually there.
Each answers one question about your website, in under a minute, without an account.
