Frequently Asked Questions:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Do I need accounts for all three services?
You'll need an OpenAI account for ChatGPT (platform.openai.com), an Anthropic account for Claude (console.anthropic.com), and/or an X.AI account for GROK (console.x.ai).

Is this extension free?
The extension itself is completely free. You only pay for API usage according to OpenAI, Anthropic, and X.AI pricing.

Is it safe to use my API keys?
Yes, your API keys are stored locally in your browser and used exclusively for direct connections to official servers.

How is this extension different from others?
We don't use intermediate servers, don't collect your data, and don't show ads. This provides direct and secure connections to ChatGPT, Claude, and GROK APIs.

What does "GROK in test mode" mean?
GROK integration is fully functional but marked as test mode as X.AI's API is relatively new. All features work as expected.
