FAQ
Can you build the AI app for both Android and iOS?
Yes, I use Flutter so one codebase ships to both stores, cutting your cost and timeline in half.
Which AI models can you integrate?
ChatGPT (GPT-4, GPT-4o), Claude, Gemini, DeepSeek, Whisper (voice), DALL-E and Stable Diffusion (image), ElevenLabs (TTS). I'll recommend the best one for your use case.
Do I need my own OpenAI / API key?
Yes, you'll need your own API keys for production so usage costs go directly to you. I'll guide you through setting them up.
Can you handle backend, authentication, and payments?
Absolutely. I'm full-stack — I build the backend (Node.js, Firebase, Supabase), handle auth, and integrate payments (Stripe, RevenueCat, and many more).
Will I own the source code?
100%. You receive the full Flutter project, documentation, and deployment instructions.
Do you submit the app to App Store and Play Store?
Yes, included in Premium. You'll need your own developer accounts
Can you sign an NDA?
Of course. I respect client confidentiality and sign NDAs on request.
What if I only have an idea — no design or specs?
That's fine. I'll help you scope the MVP, suggest features, and recommend a design approach during our first call.
