The fastest way to experience PolyChat-AI is through our live demo. No installation required.

Get Started in 3 Steps

1

Open PolyChat-AI

Configure Your API Key

On first launch, you’ll see an onboarding modal. Here’s how to get your free OpenRouter API key:
  1. Visit OpenRouter.ai
  2. Sign up for a free account
  3. Navigate to Keys in your dashboard
  4. Click Create Key to generate your API key
  5. Copy the key and paste it into the PolyChat-AI onboarding modal
OpenRouter offers a generous free tier to get started. Your API key is stored securely in your browser’s localStorage and never sent anywhere except to OpenRouter.
3

Start Your First Conversation

After entering your API key:
  1. Select your preferred model (we recommend GPT-4o or Claude 4 Sonnet to start)
  2. Click New Conversation or use the keyboard shortcut Ctrl/Cmd + N
  3. Type your message in the chat input
  4. Press Enter or click the send button
  5. Watch as the AI responds in real-time with streaming text
Your first message may take a few seconds as the model initializes. Subsequent messages will be faster.
