FAQ
What kind of files can you support?
I support PDF, DOCX, TXT, CSV, and scraped website content.
Is my data safe?
100% — your data is processed securely and stays private unless you request deployment.
Will the chatbot work offline?
The basic version does not require online calls, but GPT-based models require internet access.
Do I need an OpenAI API key to use this?
Yes, for the GPT-based chatbot (Standard and Premium), you'll need your own OpenAI API key. I’ll guide you through getting it if you don’t have one.
Can I update the chatbot with new documents later?
Definitely! I’ll show you how to add or update documents so your chatbot stays current.
Can this chatbot be embedded in my website?
Yes — in the Premium package, I can deliver the chatbot as a standalone web app or an embeddable widget for your site.
Can I use a different AI model like Claude or LLaMA?
Yes! I can integrate open-source or third-party models if available through API or local inference. Let me know your preferences before ordering.
What tech stack will you use?
Typically LangChain or LlamaIndex for orchestration, ChromaDB or Pinecone for vector storage, and OpenAI or HuggingFace for LLMs. The frontend is usually in Streamlit, React, or Next.js — depending on your needs.
Can you deploy the bot for me?
Yes — deployment to platforms like Vercel, Render, or DigitalOcean is included in the Premium package. I also offer custom deployment as a gig extra if needed.
Does this support multilingual documents?
Yes! The chatbot can handle and respond in multiple languages if the underlying model supports it (e.g., GPT-4 or Claude).
