I will integrate ai chatbot or llm into your website or app with fastapi

Add a working AI chatbot to your website or app, without weeks of setup.

I integrate OpenAI, Anthropic Claude or Google Gemini into your project with a clean FastAPI backend and a streaming chat interface, so answers appear word by word like in ChatGPT.

WHAT I CAN BUILD

Streaming chat widget or a full chat page (React)

Your choice of provider: OpenAI, Claude or Gemini

Custom system prompt, so the bot speaks in your brands voice

User login and saved chat history

Rate limits and usage limits to control costs

Secure API key handling (keys are never exposed in the browser)

HOW IT WORKS

1. Tell me about your project and your AI provider
2. I confirm scope and timeline
3. I build it and test it with your test API key
4. You receive the source code and setup notes

You provide your own API key from the provider. Searching your own documents (RAG) is not included in the packages, message me first if you need it.
