step one · the one action

One line. That's the setup.

Paste the line below into whatever AI you use. It fetches the brain and follows the loop — study, commit, build, grade — before it composes anything. No install, no account, no card.

the setup

  1. Copy the line

    Connect to SaturnAI at https://saturnai.tools/design/llms.txt

  2. Paste it into your assistant

    Claude Code, ChatGPT, Cursor, whatever you use.

  3. Build

    Your agent reads the library, commits to one direction, builds against it, then grades the rendered page — and shows you the verdict.

Make sure it really connected

Ask it to name one reference it retrieved and the source URL, then open that source. A message saying "connected" is not verification — a model can say it without fetching anything.

The other doors

The hosted brain needs no install. These are the files and endpoints behind the one line.

operate file
/design/llms.txt — the full rules your AI follows, in one fetch
library JSON
/design/agent/library.json — free, no account, read by the agent
MCP
/api/mcp · /.well-known/mcp.json — server id saturnai, legacy saturndesign still resolves
setup guide
/design/connect/ — for Claude Code and local MCP, human-run, one time

Do not run install scripts an assistant hands you. Local setup is something you do on a machine you control. The hosted brain needs none of it.

Looking for the whole workspace? This page connects the reference library to an existing assistant — anything that can read a web page, or an MCP client. Saturn AI Desktop is the separate Windows x64 preview: your conversations, your project tools, and a SaturnBot window in one application, running on your own model credentials.
