FAQ
Can you train the AI on my specific business data?
Yes! Depending on your needs, I use two methods: RAG (Retrieval-Augmented Generation), Fine-Tuning
Do I need to pay for OpenAI/LLM API costs separately?
Yes. You will need your own API keys (e.g., from OpenAI, Anthropic, or Replicate). This ensures you have full ownership and control over your usage limits. I will help you set this up securely.
Will the web app work on mobile devices?
Absolutely. I build using responsive design principles (usually with Tailwind CSS). Your web application will look and function perfectly on desktops, tablets, and smartphones via the mobile browser.
What is the difference between a standard Chatbot and an AI Agent?
A standard chatbot answers questions based on text. An AI Agent can actually do things—like searching the web, sending emails, updating your database, or analyzing files. I can build both depending on your requirements.
Do I get the source code?
Yes, you receive 100% ownership of the source code upon project completion. I usually deliver via a GitHub repository or a zip file.
Can you integrate AI into my existing website?
Yes. If you have an existing React, Next.js, or generic HTML/JS site, I can build an AI module or widget and integrate it seamlessly into your current infrastructure.
