+
+Interactive TUI for browsing your LanceDB database.
+
+## Installation
+
+```bash
+# For haiku.rag-slim

+haiku-rag inspect --db /path/to/database.lancedb
+```
+
+## Interface
+
+![Inspector with search](img/inspector-search.png)
+
+Three panels display your data:
+
+- **Documents** (left) - All documents in the database
+- **Chunks** (top right) - Chunks for the selected document
+- **Detail View** (bottom right) - Full content and metadata
+
+## Navigation
+
+**Keyboard:**
+
+- `Tab` - Cycle between panels
+- `↑` / `↓` - Navigate lists
+- `/` - Open search modal
+- `q` - Quit
+
+**Mouse:** Click to select, scroll to view content
+
+## Search
+
+Press `/` to open the full-screen search modal:
+
+- Enter your query and press `Enter` to search
+- **Left panel**: Search results with relevance scores `[0.95] content preview`
+- **Right panel**: Full chunk content and metadata
+- Use `↑` / `↓` to navigate results - detail view updates in real-time
+- Press `Enter` on a result to close search and navigate to that document/chunk
+- Press `Esc` to close search without selecting
+
+Search uses hybrid (vector + full-text) search across all chunks. Content is rendered as markdown with syntax highlighting.
