FAQ
Do you need access to my data or systems?
Only what is needed. For RAG I need your documents or website URL. For API builds I need your API keys. Everything stays confidential I can sign an NDA.
What are the ongoing API costs after delivery?
My fee covers building the system. You will need your own OpenAI API key. Typical small-business usage is $5–30 per month. I help you set this up.
Can you add the chatbot to my existing website?
Yes. I embed it as a chat widget via a JS snippet for any site WordPress, Webflow, Next.js, or HTML.
Do I get the source code?
Always. Full source code, clean comments, and a README with setup steps. You own everything I build.
What if my project is more complex?
Send me the details and I will send a custom offer. Complex LangGraph multi-agent systems are welcome.
