I will build rag ai chatbot with langchain for website and whatsapp
Abdul Basit
About this gig
Still answering the same customer questions manually? And generic AI chatbots just make up answers about your business.
I build custom RAG (Retrieval-Augmented Generation) chatbots that read your PDFs, manuals, and website in real time and answer strictly from your data. No hallucinations, no guessing.
What your AI assistant does:
- Trains on your PDFs, Word docs, manuals, and website URLs
- Embeds on your website or connects to WhatsApp
- Remembers context across long conversations
- Answers only from your approved data never invents facts
- Hands off to a human agent when things get complex
Built with Python, FastAPI, LangChain, and vector databases (Pinecone/Chroma). You get clean documented code and full ownership no platform lock-in.
Packages: Doc-Trained Demo Website AI Assistant Omni-Channel AI Agent.
Message me before ordering with a sample document and I'll build a quick proof-of-concept for you to test.

Tired of AI voice bots that break under real call volume?
I build production-grade AI Voice Agents, calling bots, and full-stack web apps—not basic wrappers. I engineer custom telephony systems (Asterisk/ViciDial) with real-time LLM, STT, and TTS pipelines. Currently in production: sub-1.5s AI latency, 98% natural voice output, and high-concurrency call handling with zero lag. You get scalable MERN/FastAPI backends, clean code, and 24/7 automated call workflows you fully own. No per-minute platform lock-in.
Message me to build a system that actually works.

FAQ
What is RAG and why do I need it?
Standard AI chatbots make things up (hallucinate). RAG forces the AI to search your specific documents first and only answer based on those facts. It guarantees accuracy for your business.
Can it read my entire website?
Yes. For Standard and Premium packages, I can scrape and index your website URLs alongside your uploaded PDFs and Notion docs.
Do I need to pay for AI APIs?
Yes, you will need an OpenAI or Groq API key to power the brain. They are very cheap (fractions of a cent per chat). I will guide you through setting it up.
What do you need from me to start?
The PDFs, Word docs, manuals, or Notion links you want the bot to learn from, plus where you want it embedded (website or WhatsApp).
