About this gig

Does your team spend too much time searching through PDFs, manuals, policies, or internal documents to find simple answers?


I can build a document chatbot that uses vector search and retrieval-augmented generation (RAG) to find relevant information from your approved documents and use it to answer questions. Instead of manually searching through files, your team can ask questions in plain language and retrieve relevant passages more easily.


What I can build for you:

  • AI chatbots for PDFs and other supported documents
  • Document processing and text extraction
  • Vector database setup and semantic search
  • RAG pipelines for document-based answers
  • Custom question-and-answer behavior
  • Source references or citations where supported
  • API integration and a simple chat interface
  • Testing with sample questions and documents


Whether you need an internal knowledge assistant or a document chatbot for your users, I can help define and build a solution around your actual information.


Send me a sample of your documents and explain what users need to find. We can start with a clear, manageable scope.
