FAQ
Do I need an OpenAI API key?
Yes, you'll need your own OpenAI API key (takes 5 minutes to get at platform.openai.com). I'll guide you through the setup. Monthly API costs are typically $5–$20 for most small business chatbots.
Can the chatbot be trained on my company's documents and website content?
Absolutely — that's the whole point. I build RAG (Retrieval-Augmented Generation) systems that train the chatbot on your PDFs, docs, URLs, or custom database so it answers questions specific to your business, not generic responses
What platforms can the chatbot be added to?
Any website (React, Next.js, WordPress, Webflow, plain HTML), mobile apps, WhatsApp (Standard/Premium), Slack, or any platform with an API. If you're unsure, message me and I'll confirm.
Will I own the source code?
Yes. You get the complete, clean, documented source code. No black boxes, no vendor lock-in. You can take it to any developer to maintain or expand it later.
What if I need changes after delivery?
Each package includes revision rounds. I also offer 7-day post-delivery support on Standard and Premium to fix any bugs or make small adjustments. For ongoing updates, add the monthly maintenance package.
