Watch one get built.

One sentence goes in. The analysis sets the brand, the plan writes itself against a real market, the deck inherits the positioning, and the page ships. Pick an idea and follow it through.

The market is not short of sitters

The UK pet-care market reached £8.2bn in 2025. Sitting and boarding is the fastest-growing segment at 14% CAGR — but supply was never the constraint. Trust is.

Narrowing to verified sitting and boarding gives a defensible £1.4bn SAM, which is the figure an investor will actually press on.

The obvious worry

Two founders, same brief, different site.

You are right to assume a generator produces one template with your name dropped in. So the page composition is drawn from a seed derived from your idea itself — your layout is stable across regenerations and unlike anyone else's. The copy has a banned-words list, which is why you will not read the word “revolutionary” on anything this makes.

After the first eight minutes

It keeps working on the thing you built.

Ask it anything and it answers with your business in context — your market, your stage, the numbers already in your plan. Or switch it to agent, describe a change, and it edits the document itself. Every edit is undoable.

Chat
Asks and answers. Nothing changes on the page.
Agent
Edits the document in place, and tells you what it touched.
Memory
Your team, your tone, your no-go zones — in every prompt.

The TAM reads inflated. Tighten it and cite the source.

Narrowed from the full £8.2bn market to sitting and boarding only. That gives a defensible £1.4bn SAM with a citation an investor can check — which is what they will press you on first.

What it costs

Including what it costs us.

There is no logo bar on this page, because there is not an honest one to show yet. So here is the arithmetic instead. You are metered in credits, one credit is about a penny of real model spend, and a complete project — idea read, plan written, deck designed and rendered, page built and published — is roughly 100 of them.

You start with 130. That is a whole project, plus room to argue with it afterwards, before anyone asks you for a card.

A failed generation is refunded automatically — you are not charged for something we did not deliver. Uploaded documents are parsed locally and cost nothing.

Before you start

The fair questions.

Do I own what it makes?

As between you and us, yes — what you generate is yours to use. Treat it as a strong first draft rather than a finished document: verify the figures before a plan goes in front of an investor, and a legal-style template is not a substitute for a lawyer. The terms say this in full.

Where does my idea actually go?

To generate anything, the text you provide is sent to third-party model providers through our routing provider, and only what the request needs is sent. Your workspace is private to your account, and nothing is public until you publish a page yourself. Don't paste secrets — passwords, keys, card numbers — into a generation. The privacy policy is specific about this.

Is the landing page really live, or just a preview?

Live. Publishing puts it on a real address you can send to anyone, served over HTTPS, with its own slug. You can unpublish it again whenever you like, and republish to the same URL. On the free plan it carries a small attribution badge; paid plans don't.

What if it gets something wrong?

You edit it — every document, slide and section is yours to change. Or you tell your co-founder what is wrong: in chat it answers with your business in context, and in agent mode it rewrites the document in place, names the sections it touched, and lets you undo the whole edit if you disagree.

Can I get the files out?

Plan documents export as PDF or Word, the deck exports as PDF, and the entire workspace downloads as a single zip. Your landing page is HTML you can host anywhere. Nothing is trapped in here.

What happens when I run out of credits?

Nothing disappears. Everything you have already made stays readable, editable and exportable, and any page you published stays up. Credits only gate new generation — top up or move to a paid plan when you want more.

Someone is going to ask you tomorrow.
