# Stellaris Companion Field Manual

Stellaris Companion turns a changing Stellaris campaign into context that humans can inspect and AI agents can reason over. This manual explains the system from the first save import to advisor briefings, Chronicle stories, and local MCP connections.

## Start in three steps

1. **[Install Stellaris Companion](/docs/start-here/install):** download the desktop app for macOS, Windows, or Linux.
2. **[Connect your first save](/docs/start-here/connect-your-first-save):** let the Companion discover a campaign or import a `.sav` file.
3. **[Ask your first question](/docs/start-here/ask-your-first-question):** use the Advisor or connect an AI app once your campaign is ready.

Completing those three steps is enough to get a campaign-grounded answer. Everything else in the manual is optional depth.

## Other routes

- **Connecting an AI app?** See the [AI app connection guide](/docs/ai-app-connections).
- **Trying to understand the architecture?** Read [how Stellaris Companion works](/docs/how-it-works).
- **Solving an in-game problem?** Browse the [strategy guides](/guides).

## One platform, two reading modes

Every manual page has an HTML version for people and a clean Markdown twin for agents. Agents can discover the complete corpus through [`/llms.txt`](https://galacticfilingcabinet.com/llms.txt) or fetch a single page through its **Read as Markdown** link.

## What the Companion does

1. Watches or imports local Stellaris saves.
2. Parses campaign state into a local historical archive.
3. Produces focused, perspective-aware briefings.
4. Lets supported AI clients request those briefings through a local MCP bridge.
5. Helps you turn campaign events into a readable Chronicle.

Raw save files remain on your computer. See [privacy and data flow](/docs/how-it-works/privacy-and-data-flow) for the exact boundary.
