FAQ
Do I need my own OpenAI or Anthropic API key, and who pays for usage?
Yes, you will need your own OpenAI, Claude, or Gemini developer account and API key. The API usage costs are paid directly by you to the provider, ensuring you retain 100% privacy and control over your data.
Can you protect my API key and prevent users from abusing my token quota?
Absolutely. Your API keys are kept strictly on the secure backend (never exposed to the client browser). I also implement user credit/token limits and rate-limiting so users cannot spam or abuse your API balance.
How can I monetize this AI web application?
I can integrate Stripe to enable recurring monthly/annual subscription plans, one-time credit top-ups, or pay-per-generation pricing models directly on your platform.
Do I own the source code after the project is completed?
Yes, 100%. Upon completion, the entire GitHub repository and all deployment configurations are transferred directly to you. You retain full commercial ownership of your product.
