I will integrate openai and build rag chatbots for your web app
Yurii K
About this gig
I add focused AI features to web applications using OpenAI or Anthropic APIs.
Basic covers one text-based API function in your existing app, such as summarization. Standard is a RAG API that answers questions using up to 20 text documents, 200 pages total, with source citations. Premium adds a React chat interface, authentication and chat history to the same document scope.
I've worked on RAG-based document generation, retrieval, citations and document integrations in production software. We'll agree on the inputs, expected outputs and citation format before starting.
You'll receive source code, setup instructions and checks for the agreed behavior. Model usage fees, hosting, deployment, scanned-document processing and maintenance are separate. Revisions cover the original scope; new features need a separate offer.
Message me with your use case and current stack before ordering.
