FAQ
What do you need from me to start?
I will need a clear overview of your application idea, any preferred UI styles or branding preferences, and your OpenAI or Gemini database credentials. If you have custom data for the RAG component (like PDFs or spreadsheets), please prepare those as well!
Do I need my own OpenAI or Gemini API Keys?
Yes, you will need to provide your own API keys. Don't worry if you don't have them yet—I will guide you step-by-step on how to obtain them securely and explain how to add them as environment variables.
What is a RAG (Retrieval-Augmented Generation) application?
A RAG system connects the AI model (like Gemini or GPT) directly to your own custom knowledge base (PDFs, sites, or databases). This ensures the chatbot answers user queries strictly using your accurate, personalized business data rather than generic web information.
Will you assist with hosting and deployment?
Absolutely! I will guide you through or directly assist with deploying your front-end (on Vercel, Netlify) and your server-side API (on Railway, Render) so that your application is live and accessible online.
Is the source code fully included?
Yes, full ownership and clean, well-commented source code are delivered with the Standard and Premium packages, or can be added as a custom gig extra.
