FAQ
What is a RAG chatbot and how is it different from a normal chatbot?
A normal chatbot gives generic answers. A RAG chatbot reads your actual business documents and gives accurate, specific answers based on your real data.
What file types can I provide as my knowledge base?
You can provide PDFs, DOCX, Excel sheets, plain text files, or even a website URL. I'll handle the rest.
Which AI model will be used for my chatbot?
our choice — OpenAI (GPT-4), Claude, Gemini, or Groq. I'll recommend the best one based on your budget and use case.
Will I own the source code after delivery?
Yes, 100%. Full source code is delivered with every package — it's yours forever.
Can I update or add new documents to the chatbot later?
Yes. Standard and Premium packages include an admin panel so you can add, update, or remove documents anytime without my help.
Do you offer support after delivery?
Yes. I offer maintenance and upgrades after delivery. Message me and we'll work out a plan that fits your needs.
