I will build langchain website chatbot openai chatbot ai assistant customer support
Gael Santamaria
About this gig
A useful customer support chatbot needs more than a good prompt. It needs the right information, a sensible retrieval strategy, and a workflow designed around the questions your customers ask.
I'm Gael Santamaría, and I develop LangChain-based website chatbots for businesses that need more flexibility than a basic chatbot integration can provide.
Depending on your requirements, I can help build an assistant that retrieves relevant information from your knowledge sources, maintains conversation context, and generates responses using an appropriate language model.
WHAT I CAN BUILD
- LangChain chatbot development
- Retrieval-augmented generation (RAG) setup, where appropriate
- Integration with an approved document or knowledge source
- Vector database or retrieval configuration, where required
- Conversation history and contextual responses
- Model and prompt configuration
- Website chatbot or API integration
- Basic error handling and response testing
- Technical handover documentation
LET'S BUILD A CHATBOT THAT FITS YOUR WORKFLOW.
Message me with your project idea, and I'll review the technical needs and recommend a suitable starting point.

FAQ
What is the difference between LangChain and a regular AI chatbot?
LangChain is a framework for building applications around language models. It can help connect models to data sources, retrieval systems, tools, and workflows. A simple website chatbot may not need it, but a more customized solution sometimes benefits from the additional flexibility.
What is RAG?
Retrieval-augmented generation allows a chatbot to retrieve relevant information from an external knowledge source before generating an answer. It can improve the relevance of responses but does not guarantee accuracy.
Can you connect my chatbot to a vector database?
Yes, if the selected database is compatible with the agreed architecture. One supported retrieval backend is included in the Standard and Premium packages.
Can you deploy the chatbot to my server?
Deployment assistance to one agreed environment is included in Premium. Hosting configuration, server provisioning, advanced DevOps, and production infrastructure may require a separate quote.
Can I use OpenAI or another language model?
Yes, subject to provider compatibility and the agreed implementation. Please specify your preferred model and whether you already have the required API access.
Is this suitable for a large enterprise knowledge system?
It can be a starting point, but enterprise systems often require additional security controls, access permissions, monitoring, evaluation, and scalability work. Those requirements should be assessed before ordering.
