FAQ
What is a RAG chatbot?
A RAG (Retrieval-Augmented Generation) chatbot connects an LLM like Gemini to your private data (websites, PDFs), ensuring it answers only based on the specific information you provide.
How does the knowledge base stay updated?
I set up automated GitHub Actions (Cron jobs) that scrape your data sources and rebuild the vector database weekly, ensuring your AI never provides outdated information.
Are there high monthly costs for the LLM?
No. I specialize in zero-cost architectures. By leveraging the free tiers of Google AI Studio and Hugging Face, you can run a production-ready bot with zero monthly API fees.
Is it easy to integrate into my existing website?
Absolutely. You will receive a simple HTML snippet. You just need to paste it into your website's code to have the chat widget live instantly.
