About this gig

Turn your PDFs, business documents, website content, and internal knowledge into an intelligent AI assistant.


I will build a custom Retrieval-Augmented Generation, or RAG, chatbot that answers questions using your own information. The assistant can retrieve relevant content, generate accurate responses, and display source citations so users can verify where each answer came from.


This service is ideal for companies, consultants, schools, legal teams, HR departments, SaaS businesses, and knowledge-based organisations.

The solution may include document ingestion, text chunking, embeddings, vector database integration, conversational memory, source citations, API development, and a simple web interface.


Depending on your requirements, I can work with OpenAI, LangChain, LangGraph, FastAPI, PostgreSQL, Pinecone, Chroma, Qdrant, or similar technologies.

You will receive clean source code, setup instructions, and a solution designed around your specific documents and business use case.


Please contact me before ordering to discuss your data sources, required features, and deployment needs.
