OpenAI-Powered Chatbot — GPT Assistant for Website or App

I will build a GPT-powered AI chatbot for your website or application — integrating the OpenAI API with a custom system prompt defining your bot's persona and knowledge boundaries, conversation history management within the context window, streaming response rendering, and a clean chat interface. Unlike rule-based bots, an OpenAI-powered chatbot can handle natural language variation and unscripted questions, but only when the system prompt is engineered correctly to keep responses on-topic, on-brand, and within appropriate knowledge boundaries — a generic system prompt produces a bot that hallucinates or wanders off-topic.

The build covers OpenAI API integration with secure backend proxy (protecting your API key), system prompt engineering for persona and scope, conversation history management with token budget handling, streaming response UI, and a chat widget interface for your website or app.

This service suits businesses wanting a more flexible, natural-feeling chatbot than rule-based logic provides, for general assistance, light support, or engagement use cases without requiring deep integration with proprietary data.
