My Portfolio
FAQ
Which AI chatbot providers do you work with?
I primarily integrate OpenAI (GPT models), Anthropic's Claude, and Google's Gemini. I can recommend the best fit based on your budget and use case if you're not sure.
Do I need my own API key for the AI chatbot?
Yes, you'll need your own API key from OpenAI, Anthropic, or your chosen provider. This keeps your usage costs and data under your own account. I'll guide you through getting one if you don't already have it.
Can the AI chatbot be trained on my own content or documents?
Yes, I build RAG-based (Retrieval-Augmented Generation) assistants that answer using your documentation, product data, or knowledge base instead of generic responses.
How much will the AI API cost to run each month?
This depends on your usage volume and which model you choose. I'll help you estimate expected costs upfront and can recommend cheaper models (like Gemini or GPT-4o-mini) if budget is a concern.
Will the AI chatbot work with my existing app?
Yes, I can integrate AI chatbot features into an existing React, Next.js, or Node.js app, or build a new one from scratch.
Which databases do you use for storing chat history or context?
I typically use MongoDB or a vector database like Pinecone for RAG-based context, and can connect to PostgreSQL or your existing database if needed.
What if my project needs more than what's listed in the packages?
Message me with your requirements before ordering and I'll create a custom offer.
How do you handle data privacy and security with AI APIs?
User data sent to OpenAI, Claude, or Gemini follows that provider's own data policies, which I'll explain upfront. I avoid storing conversation data beyond what's needed, and can add safeguards like anonymization if your project requires it.
Is this compliant with regulations like GDPR?
I can build with GDPR-friendly practices in mind, such as minimal data retention and clear user consent flows, but I'm not a lawyer. For projects with strict compliance requirements (healthcare, finance), I'd recommend having your own legal review before launch.
Do you offer maintenance after the chatbot is live?
Yes, all packages include a short post-delivery support window for bugs related to the original scope. For ongoing maintenance, monitoring, or feature updates beyond that, I can offer a separate maintenance arrangement — message me to discuss.
