2. Make the chat interface intuitive: Users should be able to easily navigate the chat interface and find the information they need.

3. Use clear and concise language: Avoid using technical jargon or complex language that users may not understand.

4. Personalize the experience: Tailor the app's responses to the individual user's preferences and behaviors.

5. Provide helpful recommendations: Use the AI technology to provide relevant suggestions and solutions to the user's inquiries.

6. Test and refine: Continuously test the app's performance and user experience, and make necessary improvements based on user feedback.
