About this gig
Looking for a smart RAG AI chatbot for your website, SaaS, support system, or internal knowledge base?
I will build a custom RAG AI chatbot using MERN stack, Node.js, Express, vector database, and LLM integration. Your chatbot can retrieve accurate answers from PDFs, documents, websites, FAQs, or business data and respond in a fast, user-friendly chat interface.
What I can build:
- MERN based chatbot dashboard and frontend
- Node.js and Express backend APIs
- RAG pipeline with document retrieval
- Vector database integration
- LLM integration
- Chat UI for website or admin panel
- File or knowledge base ingestion
- Source-aware answers
- Authentication and role-based access if needed
- Deployment support
Best for:
customer support, company knowledge base, SaaS assistant, document Q&A, internal team chatbot, and AI support tools.
I focus on clean architecture, scalable backend logic, and a professional chatbot experience that fits real business use.
Message me before ordering if you need a custom scope.
