FAQ
What is an AI chatbot with RAG, and why do I need it?
A standard chatbot often "hallucinates" or gives generic answers. By using RAG (Retrieval-Augmented Generation), I connect your ai chatbot to your specific business data (PDFs, URLs, or databases), ensuring it provides accurate, context-aware responses grounded in your private information.
How does LangChain improve my chatbot?
LangChain is a powerful framework that allows me to build "chains" of thought for your bot. As your ai engineer, I use it to give your chatbot long-term memory, the ability to query multiple data sources, and complex reasoning capabilities that basic platforms can't offer.
Can you integrate the chatbot with the WhatsApp API?
Yes. I can deploy your custom langchain agent as a whatsapp ai chatbot. This allows your customers to interact with your business 24/7 on their favorite messaging app with the full power of your custom AI.
Is my private business data secure with an AI chatbot?
Absolutely. Your data is used only as context for the ai chatbot to answer questions. Depending on your needs, I can use local vector databases or secure cloud solutions like Pinecone to ensure your information remains private and protected.
What do I need to provide to get started?
I typically need your OpenAI API key (or a preferred LLM provider) and the documents you want the bot to learn from (PDFs, CSVs, or website links). If we are building a whatsapp ai chatbot, you will also need a verified Meta Business account.
