FAQ
What data formats do you support?
I can ingest PDFs, Word docs (.docx), Excel files, CSVs, plain text, websites/URLs, Notion pages, and SQL databases. Let me know your format before ordering.
Do I need an OpenAI API key?
Yes, you'll need your own API key (OpenAI, Anthropic, or Google). This keeps your data private and gives you full control over costs. I'll guide you through the setup.
Will the chatbot hallucinate or make up answers?
RAG chatbots are specifically designed to answer only from your documents — greatly reducing hallucinations. I also add source citations so users can verify answers.
Can I embed it in my website?
Yes! The Standard and Premium packages include a deployable web app. The Premium package includes a React chat widget you can embed directly into any website.
Do you provide the source code?
Absolutely. You receive all source code, a README, and setup instructions. You own everything delivered.
