ModusBrain turns scattered company knowledge into a **shared, searchable brain** for people and AI agents. It keeps the source material, the context behind it, and the work based on it in one place.

Instead of asking an agent to guess from a folder of documents, you give it current context, clear operating guidance, and an audit trail for important actions.

## How it fits together

1. **Bring in your source material.** Add Markdown files, repositories, meeting notes, and connected data sources.
2. **Build a usable knowledge layer.** ModusBrain indexes content, extracts links and facts, and keeps pages connected over time.
3. **Give agents the right context.** Agents can search, reason over, and follow the approved guidance in your brain.
