Getting Started

Duplex is a free, browser-only AI frontend. No installation, no backend, no account required.

What you need

• A modern browser (Chrome, Firefox, Safari, Edge)
• At least one API key OR a local model server (Ollama, LM Studio)
• Internet connection (for cloud providers; local-only works offline)

Quick start

1. Launch the app: Go to the chat interface.
2. Add endpoints: Paste your API keys or configure your local server.
3. Toggle them on: Enable the endpoints you want to use.
4. Send a prompt: Type your message and watch all models respond simultaneously.

That's it. No configuration files, no environment variables, no backend setup.
