FAQ
I only have an AI idea. Can you help me turn it into an MVP?
Yes. Send your idea, target users, key features, and any reference app. You do not need a finished specification; I can help turn your idea into a clear MVP scope before development starts.
What technologies do you use to build the AI MVP?
I use Next.js and React for the frontend, Supabase for database/auth, and OpenAI for AI features. I can also work with APIs such as Stripe and other AI providers when your scope requires them.
Do I need to provide my own OpenAI API key?
Yes. You can provide your own OpenAI/API keys so usage stays under your control. I will guide you through the setup and keep credentials out of the source code.
What is your step-by-step process for building my MVP?
Yes. The process is: review your requirements → define the MVP scope → plan the architecture → build the UI and core features → integrate AI/APIs → test and fix issues → deploy and hand over the project.
What results can I realistically expect from an AI MVP?
An MVP is designed to validate the core idea, not include every future feature. You can expect a functional AI product within the agreed scope, with the foundation ready for future improvements.
What if I need features that are not included in my package?
The package limits are based on features and complexity. Extra features, advanced AI agents, RAG, complex APIs, large dashboards, or major changes outside the agreed scope require a separate quote.
Will I receive the source code after the AI MVP is completed?
Yes. You receive the completed project and source code included in the agreed package. I build with maintainable structure so you can continue improving the MVP after delivery.
