FAQ
What do I need to provide to get started?
Just share your documents, PDFs, URLs, or a description of what your chatbot should know and how it should respond. I handle everything else from there.
Can the chatbot be trained on my own business data?
Yes. That is exactly what RAG does. I feed your documents into a vector database so the chatbot answers only from your content with high accuracy.
What platform will the chatbot be deployed on?
I deliver a Streamlit web app or FastAPI backend depending on your package. Both are easy to run locally or deploy on any cloud platform.
Will I own the source code?
Yes. You receive complete source code, fully documented with no restrictions. It is yours to modify, extend, or deploy however you need.
Does it work in languages other than English?
Yes. OpenAI models support multiple languages. If you need Urdu, Arabic, French, or any other language just mention it before ordering.
