## Using Evidence Lab

Now that you have Docker running (`docker compose up -d --build`), open your browser and navigate to:

**[http://localhost:3000](http://localhost:3000)**

This is the Evidence Lab user interface. From here you can search your document corpus, build research trees, create heatmap visualizations, and rate AI-generated content.

Use the navigation bar at the top to switch between the main features:

- **Search** — find documents using natural language queries with AI-powered summaries
- **Heatmapper** — visualize document distribution across attributes
- **Research Trees** — drill down into topics with structured, multi-level research
- **Research Assistant** — chat-based AI agent that searches, analyzes, and synthesizes findings with inline citations, multi-turn conversations, and an optional Deep Research mode for thorough investigations
- **Monitor** — track pipeline performance and corpus statistics (admin)

The guides in this section walk you through each feature in detail.
