About this gig

Looking for a custom AI chatbot that can answer questions using your own documents or business data?

I will build a professional Generative AI chatbot using Python, RAG (Retrieval-Augmented Generation), LangChain, and modern LLM technologies.

I can create AI assistants for PDFs, documents, knowledge bases, websites, internal business information, FAQs, and other custom data sources.

What I can provide:

Custom RAG chatbot development

Python and LangChain implementation

Document/PDF knowledge-base integration

Vector database integration

LLM/API integration

Conversational AI workflows

Integration with an existing web application (Standard/Premium)

Clean source code

Custom functionality based on your requirements

Every project is different, so the final architecture and integrations will depend on your requirements and selected package.

Please message me before ordering for complex or custom projects so we can confirm the scope, integrations, timeline, and best package.
