FAQ
What type of AI chatbots can you build?
I can build RAG chatbots, custom GPTs, AI assistants, multi-agent systems, PDF/document chatbots, voicebots, and fully local/private AI chatbots. They can run on OpenAI, Llama, DeepSeek, Gemini, LangChain, LlamaIndex, n8n, Vector DBs, and more depending on your needs.
Do I need to provide my own API keys or data?
Yes, you will need to provide your OpenAI / Llama / Gemini API key (or any LLM provider you prefer). For RAG chatbots, you will also provide the documents, files, or knowledge base you want the chatbot to learn from. If you don’t have anything ready, I can guide you.
Can you deploy the chatbot to my website, app, or internal system?
Absolutely. I can deploy your chatbot. I also support embedding scripts, API integration, and secure authentication depending on the package you choose.
