# Welcome to Stratta

> Query Swiss civil-engineering norms (SIA, Eurocodes) directly from Claude — with exact, verifiable citations.

Stratta lets structural and civil engineers consult Swiss building norms — SIA standards
and Eurocodes — straight from a conversation with Claude. You ask a question in plain
language; Claude reads the relevant norms and answers with a precise citation to the exact
section and page.

It works through a small program called an **MCP server** that you install once in your
Claude client. After that, the norms become part of every conversation.

## What you get

<CardGroup cols={2}>
  <Card title="Exact citations" icon="quote-left">
    Every technical claim is backed by `[Norm path, p. XX]` — pointing to a section Claude
    actually opened, never invented.
  </Card>

  <Card title="No AI background needed" icon="user-check">
    Talk to Claude the way you already do. Stratta gives it the norms; you read the answer.
  </Card>

  <Card title="Cross-norm reasoning" icon="link">
    SIA distributes a rule across several norms (260 / 261 / domain). Claude follows the
    cross-references so the answer is complete.
  </Card>

  <Card title="Your norms stay private" icon="lock">
    Norms are scoped to your organization. You bring the documents you are licensed for;
    no one else sees them.

## How a session looks

<Steps>
  <Step title="You ask">
    "According to SIA 261, which variable loads apply to an office floor, and how do I combine
    them at ULS?"
  </Step>

  <Step title="Claude navigates">
    Claude lists the available norms, opens the table of contents, reads the relevant sections,
    and follows cross-references to SIA 260 for the load combinations.
  </Step>

  <Step title="You get a cited answer">
    A clear answer with the governing values and a citation like `[SIA 261, 8.2, p. 44]` you can
    open in the printed norm to verify.
  </Step>
</Steps>

## Who Stratta is for

Stratta is built for practising **civil and structural engineers** in Switzerland who work
with SIA norms and Eurocodes daily — and want a faster, verifiable way to look things up
without losing the audit trail back to the source document.
