About this gig
Summary:
Heres a 1200-character SEO-optimized Fiverr gig description for your LangChain + RAG AI chatbot service.
I build advanced AI chatbots using LangChain and Retrieval-Augmented Generation (RAG) that can understand and respond based on your custom data such as PDFs, websites, or databases. These chatbots are designed to provide accurate, context-aware answers powered by modern LLMs.
I primarily use open-source models for flexibility and cost efficiency, and I can also integrate premium models like OpenAI GPT based on your project requirements. This ensures the best balance between performance, scalability, and budget.
What I offer includes custom AI chatbot development, RAG-based knowledge systems, API integration using FastAPI, and deployment-ready solutions. These systems are ideal for customer support, document Q&A, business automation, and SaaS applications.
You will receive clean, scalable, and production-ready code tailored to your needs. Whether you need a simple chatbot or a full AI-powered system, I can build a solution that fits your use case.
Lets build a powerful AI system for your business.
