FAQ
Can the chatbot answer questions from multiple PDFs or large document sets?
Yes! The chatbot can handle multiple files and long documents using vector databases like Pinecone, FAISS, or ChromaDB.
Can you use other LLMs like Claude, Gemini, or open-source models?
Absolutely. I can integrate Claude, Gemini, Mistral, LLaMA 3, or free/open-source models if you prefer not to use OpenAI.
Can I upload new documents later?
Yes. If included in your plan, you’ll get an admin panel to easily upload new files and retrain your chatbot anytime.
Do I need to provide anything to get started?
Just your documents, OpenAI API key (if you want), and a short brief. I will handle the rest.
