FAQ
Which AI models can you integrate?
OpenAI, Anthropic Claude and Google Gemini. For answers from your own documents I add RAG with a vector database such as Pinecone, Chroma, FAISS or Qdrant.
Can you add AI to my existing web app?
Yes. I can add an AI chat, search or automation feature to an existing React, Next.js, Node.js or Laravel app through a clean API.
Do I own the source code?
Yes. You get the full source code and documentation. I can also deploy the app with Docker on your server or cloud account.
What do you need from me to start?
Your idea or feature list, any designs or examples you like, and access to existing code or API keys if needed. I confirm scope and timeline before starting.
