Libraries like BotUI, React, or Vue.js can simplify the development process and offer more advanced features.

How do I make my chatbot responsive?

Use CSS media queries and flexible layout techniques (like flexbox or grid) to ensure your chatbot adapts to different screen sizes.

Is it possible to add voice recognition to my chatbot?

Yes. You can integrate Web Speech API or third-party services like Google Speech-to-Text to add voice capabilities.
