I will build a custom ai chatbot using rag and llm


About this gig
Looking for a smart AI chatbot that actually understands your customers, not just a scripted bot that breaks on the third question?
I build custom AI chatbots using RAG (Retrieval Augmented Generation) and LLMs like GPT and Claude, trained on your own documents, FAQs, or business data so it gives accurate, context aware answers instead of generic responses.
I've built and deployed a similar AI system in production, handling real user queries end to end, from intent detection to accurate response generation. I also worked on RAG based document retrieval during a software engineering internship, so this isn't my first time shipping AI to real users.
What you get:
- Custom RAG pipeline built on your data (docs, FAQs, product info, etc)
- Integration with your preferred LLM (OpenAI GPT, Claude, or others)
- Clean, working chatbot ready to connect to your website
- Clear documentation so you're not stuck if you want changes later
Tech I use: Python, LangChain, OpenAI API, Angular, Node.js, MongoDB

FAQ
Do I need to provide the AI model or API key myself?
No, I can set it up using OpenAI or Claude, and you'll just need your own API key for ongoing usage costs. I'll guide you through getting one if you don't have it already.
Can the chatbot answer questions from my own documents or website content?
Yes, that's exactly what RAG is for. Send me your FAQs, product info, or documents and the chatbot will pull accurate answers directly from them.
How long does it take to get a working chatbot?
Basic delivers in 3 days, Standard in 5 days, and Premium in 7 days. Rush delivery is available as an extra if you need it sooner.
Do I get the source code?
Yes, source code is included in every package so you're never locked into working with me alone.
What if I'm not sure which package I need?
Message me with a quick description of what you want the chatbot to do and I'll tell you honestly which package fits, no upselling.
