I will build a custom ai chatbot with rag over your documents


About this gig
Do you have documents, PDFs, or a knowledge base that customers or your team constantly need to query? I'll build you a custom AI chatbot that answers questions accurately using only YOUR data, not generic internet knowledge.
This is called RAG (Retrieval-Augmented Generation): the chatbot retrieves the exact relevant content from your documents before generating a response. No hallucinations. No made-up answers.
What I deliver:
- AI chatbot connected to your documents or knowledge base
- FastAPI backend ready to embed in your website or app
- Vector database for fast, accurate retrieval
- Clean source code, fully documented
- Deployed and tested end-to-end
Built with Python, LlamaIndex, and OpenAI. Same stack behind Mentor CEAM (mentorceam.com), a live medical AI platform.
