# 🔀 Chat Switchboard

A sleek, OpenAI-compatible chat interface with per-conversation model switching, collapsible thinking blocks, and full chat history management.

## Features

- **Multi-Model Support**: Switch models per-chat via quick selector
- **Thinking Blocks**: Collapsible `<thinking>` tags with distinct styling
- **Streaming Responses**: Real-time token streaming with stop button
- **Chat History**: Persistent storage with export (Markdown/JSON/Text)
- **Keyboard Shortcuts**: `Enter` send, `Shift+Enter` newline, `Esc` stop, `Ctrl+B` sidebar, `Ctrl+,` settings
- **Code Highlighting**: Syntax-aware code blocks with copy buttons
- **Regenerate**: Re-run last response with one click
- **Dark Theme**: Easy on the eyes

## Quick Start

### Standalone (No Build Required)

```bash
# Build the single-file version
./build.sh

# Open in browser
xdg-open standalone/index.html
# or
python3 -m http.server 8080 --directory standalone
```

### Development

```bash
# Serve src/ directory for development
python3 -m http.server 8080 --directory src
```

```

## Backend (Planned)

The project is structured to support a full backend with:

- **Go server** with Gin/Echo
- **PostgreSQL** for persistent storage
- **User authentication** (optional)
- **API key management** per user
- **Chat syncing** across devices

### Database Schema

See `migrations/001_initial.sql` for the initial PostgreSQL schema.

### Running with Docker

```bash
docker-compose up -d
```

## Configuration

Settings are stored in `localStorage`:

| Key | Description |
|-----|-------------|
| `chatSwitchboard_settings` | API endpoint, model, parameters |
| `chatSwitchboard_models` | Cached model list |
| `chatSwitchboard_chats` | Chat history |

## API Compatibility

Works with any OpenAI-compatible API:

- OpenAI
- Anthropic (via proxy)
- Ollama (`http://localhost:11434/v1`)
- LM Studio
- LocalAI
- vLLM
