FAQ
Will the AI chatbot work seamlessly on both Web and Mobile apps?
Yes! I build unified backend endpoints and cross-platform UI components in React and React Native. This ensures your AI chatbot maintains consistent logic, performance, and user experience across Web, iOS, and Android platforms.
Can the AI chatbot be trained on my company's custom data and PDFs?
Absolutely. Using RAG (Retrieval-Augmented Generation) and vector databases like Supabase, Firebase, or Pinecone, I can train your AI assistant to read your documentation, website content, and FAQs to answer user queries accurately.
Can you publish the React Native mobile app to the App Store and Google Play?
I handle the complete cross-platform app build and build files (IPA/APK/AAB). If you need assistance uploading to Apple App Store or Google Play Store, we can add that as a Gig Extra!
