• Seamless Side Panel Integration: Chat with AI while browsing without switching contexts or tabs
• Custom Configuration: Configure your own preferred models and API settings
• Conversation History: Review your chat history within the panel
• Dark Mode Support: Toggle between light and dark themes for comfortable viewing
• Markdown Support: View AI responses with proper formatting, code blocks, and more

How to Get Started:
