FAQ
What information do I need to provide to get started?
Please share your PDF documents and describe the type of questions your users will ask. The more context you provide about the use case, the better I can tailor the chatbot.
Can I use my own LLM API key (OpenAI, Anthropic, etc.)?
Yes. I can integrate any LLM provider you prefer. If you don't have a preference, I will use Groq (Llama) by default because it is fast and cost-efficient.
Can you deploy the chatbot for me?
Yes. Deployment is included in the Standard and Premium packages. I will deploy it to a platform like Render or Streamlit Cloud and provide you with a live URL.
Will I own the source code?
Yes. For the Standard and Premium packages, you receive full ownership of the source code and documentation.
How many PDF documents can the chatbot handle?
The Basic package is designed for small collections (up to 50 PDFs). For larger document sets or complex archives, please choose the Standard or Premium package.
