FAQ
Do I need my own OpenAI API key?
Yes, you'll need your own OpenAI API key for usage costs. I'll guide you through getting one if you don't have it.
Can the chatbot answer from my own documents or website?
Yes — that's what the RAG-based package is for. I connect the bot to your PDFs, docs, or database so it answers using your content.
What platforms can this be integrated into?
Websites, web apps, Slack, Telegram, or your existing SaaS product — just tell me your platform in the requirements.
Do I get the source code?
Yes, full source code is included and yours to keep, host, and modify.
What if I need changes after delivery?
Each package includes revisions. For ongoing support beyond that, I offer maintenance as a custom add-on.
