I will build a voice ai agent with rag langchain and finetuning


Acerca de este Servicio
YOUR AI CALLS EVERY LEAD. BOOKS EVERY APPOINTMENT. 24/7.
Most businesses lose 70% of leads from slow follow-up. I build Voice AI Agents that call leads within 60 seconds, answer questions via RAG, handle objections, and auto-book appointments.

FAQ
What is the difference between your packages?
Basic is a simple Voice AI agent. Standard includes full RAG + LangChain + CRM integration (most popular). Premium adds LLM Fine-Tuning, Multi-Agent system, advanced backend and 30 days support.
What is RAG and why is it important?
RAG (Retrieval-Augmented Generation) allows the Voice AI to read your documents, PDFs, and knowledge base in real-time during calls so it never says “I don’t know” and always gives accurate answers.
Do you do LLM Fine-Tuning?
Yes. I prepare custom training data from your scripts/transcripts and fine-tune the model so it speaks your exact industry language and brand tone.
Which industries do you work with?
Real Estate, Medical Clinics, Agencies, Coaches, and SaaS businesses are my main niches.
Do you provide source code?
Yes, full source code is included in Standard and Premium packages (or as an extra).
What do I need to get started?
Just tell me your industry, use case (inbound/outbound), CRM, and any documents for RAG. I handle everything else.
