# Introduction

> What contracts.io does, in the order you meet it — and the four rules it will not break.

contracts.io is the simplest way to make a contract. You describe the deal in one
field, in your own words, and a whole contract is drafted from it in plain
language. Then you decide what happens next.

There is one field on the front page and no model behind it. Nothing is emailed,
nothing is signed, and no model reads your words until there is an account for
the work to belong to.

## What is built, and what is written down

<Columns cols={2}>
  <Card title="Live on contracts.io" icon="check">
    The door, the governing-law picker, the template catalogue, a page for every
    legal unit, and the blog.
  </Card>

  <Card title="Designed, not built" icon="pencil-ruler">
    Everything past the door's gate: the account, Lex, the room, redlines and guest
    signing — plus the whole [API](/api/introduction) and MCP surface.
  </Card>
</Columns>

Pages about the second half say so at the top. The rules below are rules the
product is built to; none of them is a claim about a date.

## The four rules

These are rules rather than features. They are true of the product wherever you
meet it, and every page in these docs is written to obey them.

<CardGroup cols={2}>
  <Card title="No AI before sign-in" icon="lock" href="/the-door">
    Your sentence is read in your own browser, by static wordlists and a handful
    of patterns. The model only ever reads your words once there is an account
    for the work to belong to.
  </Card>

  <Card title="Accepting is not signing" icon="pen-line" href="/accept-is-not-signing">
    Agreeing to the terms and putting your name to them are two acts. The paper
    always says which of the two has happened, and who did it.
  </Card>

  <Card title="Lex writes, and only writes" icon="sparkles" href="/lex">
    Lex is designed to draft, propose and explain — and never to send and never to
    sign. It reports what it <b>found</b> rather than claiming to have read
    anything.
  </Card>

  <Card title="The other side never pays" icon="users" href="/redlines-and-the-room">
    They open the paper in a browser, reply to a clause and put their name to it.
    No account to make, no fee to pay, nothing to install.
  </Card>

## What this is not

Nothing on contracts.io or in these docs is legal advice. We make paper. If your
deal needs an opinion, it needs a lawyer, and no page here will pretend
otherwise.

There are no customer logos, no testimonials and no numbers on these pages beyond
the ones the product's own data gives — how many places are in the picker, how
many kinds are in the catalogue, how many of those the door can name. We have not
earned the others yet.

<Card title="Create contract" icon="arrow-right" href="https://contracts.io" horizontal>
  The field on the homepage is the real one — the control the app mounts, not a
  picture of it.
