I will integrate a rag ai chatbot into your web app using openai, langchain


About this gig
Want your app to answer questions from your own data, without making things up?
That's what I build. I'm Saif, a full-stack developer with 5 years of experience in React, Next.js and Node. Most of my work now is adding RAG-based AI to real products.
You send me your data (PDFs, docs, website pages or your database). I turn it into an AI chatbot or smart search that lives inside your app and shows where every answer came from.
What you get:
- Full RAG pipeline: chunking, embeddings, vector search
- OpenAI, Claude or an open-source LLM
- pgvector, Supabase, Pinecone or another vector database
- Chat UI in React / Next.js, or a clean API you plug in yourself
- Source citations, so users can trust the answers
- Clean, documented code and a walkthrough video
Works with SaaS products, internal tools, customer support sites, and mobile apps through an API.
Not sure if your project fits? Message me before ordering. Tell me what data you have and what you want the AI to do, and I'll reply with an honest plan and the package that makes sense.

FAQ
I'm not technical - will I understand what you're building?
Absolutely. I explain everything in plain English. You'll understand exactly what you're getting and how it helps your business.
How long until I see results?
Most clients see working solutions within 1-2 weeks. Full implementations depend on complexity, but you'll see progress every few days.
What if my business changes?
Everything I build can be modified later. Your business isn't static; your tools shouldn't be either.
Do I need to know what technologies to use?
Nope. You tell me the business problem, I handle all the technical decisions. That's my job
Can you integrate with tools we already use?
Usually yes. Most common business tools have ways to connect. We'll discuss your specific setup.
