FAQ
Do you use OpenAI or Anthropic?
Either—your choice. I can set up provider fallback and budget caps.
Can you add RAG using my private data?
Yes—secure ingestion and a vector database so answers come from your docs.
What do you need to start?
Feature list, designs (if any), API keys/provider account, and your store accounts.
Do I own the source code?
Yes, 100%.
How do you handle privacy & costs?
I document data flows, apply content safety, and add token usage limits to avoid surprises.
