FAQ
Do I need to provide my own AI API Key?
Yes, you must provide your own API Key (Gemini/OpenAI). I will guide you step-by-step to get it from Google AI Studio and configure it safely using environment variables (.env) to protect your account.
What does "Cross-Platform" mean for my project?
It means I build a single optimized codebase that works flawlessly on both mobile (Android/iOS) and desktop (Web App). This saves you over 50% in development costs and future maintenance time.
Will the AI assistant remember past messages?
Yes! In the Standard and Premium packages, I implement a structured conversational history. The AI reads previous messages to deliver continuous, coherent, and fully natural interactions.
Can you add AI features to my existing application?
Absolutely! I can review your current codebase, integrate the AI layer by connecting the required API, and adapt your existing user interface to support the new features smoothly.
Is the visual design of the application customized?
Completely. I create high-end premium interfaces with modern dark modes, fluid micro-interactions, and responsive layouts. No cheap templates; everything is tailored to your business identity.
