knowledge booster

I want to build a fully branded AI that carries the name I choose and lives inside a mobile app. Its very first responsibility is simple yet important: answer user questions in a smooth, conversational style—just like any modern chatbot—but with deep expertise in a single knowledge domain. Whether that domain ends up being health, learning, finance, or another specialised field, the emphasis is depth rather than general chit-chat.

Here’s what I need from you: take me from concept to a published Android / iOS app. That means selecting or fine-tuning an LLM (OpenAI, Llama, etc.), integrating it into a React Native or Flutter front-end, and setting up a back-end that lets me refresh the knowledge base without shipping a whole new version. The bot must recognise and respond to its custom name, maintain fast response times, and keep user data private.

Deliverables
• Compiled iOS & Android app installs featuring the named chatbot, ready for store submission
• Clean, well-commented source code plus model files or configuration scripts
• Admin interface for updating FAQs, documents, or training data
• Short screen-recorded demo that walks through setup, renaming, and future retraining

Acceptance criteria
– Average latency ≤ 2 s for typical queries
– ≥ 90 % correct answers on a 50-question test drawn from the chosen subject
– Conforms to App Store and Google Play review guidelines

If you can guide me through hosting choices, wake-word options, and ongoing optimisation, let’s get started.
