You will get a custom RAG chatbot for your documents using Node.js and Next.js


Project details
Turn your PDFs, policies, manuals, reports, or internal documents into a searchable AI assistant.
I will build a custom RAG chatbot in JavaScript and TypeScript using Node.js, Next.js, LangChain.js, an agreed LLM provider, and a suitable vector database. Depending on your package, the solution can include document ingestion, semantic search, grounded answers, source references, a responsive chat interface, authentication, persistent chat history, document management, and deployment.
This project is suitable for internal knowledge bases, customer support, product documentation, employee handbooks, education, and research.
You will receive the source code, setup files, and documentation included in your selected package. API usage, hosting, and third-party service fees are not included.
Please contact me before ordering if you need complex integrations, scanned PDF OCR, unusual file formats, or integration into an existing application.
