How to Generate OpenAI API Key

Learn how to create and configure your custom OpenAI API key for use with VoxWrite.

Why Use a Custom API Key?

Using your own OpenAI API key gives you:

  • Pay-as-you-go pricing: Only pay for what you use
  • Higher rate limits: Access more powerful models
  • Direct billing: Transparent usage tracking
  • No subscription needed: No monthly fees from VoxWrite

Getting Your API Key

Step 1: Create OpenAI Account

  1. Go to platform.openai.com
  2. Click "Sign Up" or "Log In" if you have an account
  3. Complete the registration process

Step 2: Generate API Key

  1. Navigate to API Keys section (or visit platform.openai.com/api-keys)
  2. Click "Create new secret key"
  3. Give your key a descriptive name (e.g., "VoxWrite Extension")
  4. Click "Create secret key"
  5. Important: Copy the key immediately - you won't be able to see it again!

Step 3: Add Key to VoxWrite

  1. Open VoxWrite settings. To do this, click the VoxWrite extension icon in your browser toolbar, then click the gear icon in the top-right corner.
    Open VoxWrite settings
  2. Navigate to "API Keys" section
    API Keys section

Key Security

Best Practices

  • ✅ Never share your API key publicly
  • ✅ Store securely: Keep it in a password manager
  • ✅ Use unique keys: Create different keys for different apps
  • ✅ Monitor usage: Check your OpenAI dashboard regularly
  • ✅ Set spending limits: Configure billing alerts in OpenAI

What to Do If Compromised

  1. Revoke immediately: Delete the compromised key in OpenAI dashboard
  2. Create new key: Generate a fresh API key
  3. Update VoxWrite: Add the new key to your settings
  4. Check billing: Review your usage for any unusual activity

Usage & Billing

  • OpenAI charges based on tokens used (input + output)
  • Pricing varies by model (GPT-3.5 is cheaper than GPT-4)
  • You can set monthly spending limits in OpenAI's billing settings
  • View detailed usage in the OpenAI dashboard

Troubleshooting

"Invalid API Key" Error

  • Verify you copied the entire key (starts with sk-)
  • Check for extra spaces or characters
  • Ensure the key hasn't been revoked
  • Try generating a new key

Connection Issues

  • Check your internet connection
  • Verify OpenAI's service status
  • Ensure you have billing set up in OpenAI
  • Check if you've exceeded rate limits
