FAQ
What kind of data can the chatbot use?
The chatbot can work with PDFs, DOCX files, websites, FAQs, text files, knowledge bases, and custom business documents. I can also integrate multiple data sources based on your requirements.
Which AI models do you support?
I can integrate OpenAI GPT models, Gemini, Hugging Face models, Llama models, and other AI APIs depending on your project needs.

Yes. All packages include clean, documented source code unless otherwise specified in the project requirements.
Can you integrate the chatbot into my existing website or application?
Yes. I can integrate AI chatbots into existing web applications, dashboards, customer support systems, and business platforms.

Yes. I can assist with deployment on cloud platforms, VPS servers, Render, Railway, Hugging Face Spaces, or your own hosting environment.
What technologies do you use?
I primarily use Python, FastAPI, LangChain, OpenAI, Gemini, FAISS, Pinecone, ChromaDB, Streamlit, and Hugging Face technologies.
