FAQ
What is a RAG chatbot, and do I need one?
A RAG chatbot answers questions using your own data, such as PDFs, documents, or website content, instead of generic AI knowledge. It's ideal for customer support, internal knowledge bases, and any business that wants accurate, data-driven answers.
Which AI models do you work with?
I work with OpenAI (GPT), Claude, Gemini, Llama, and open-source models from Hugging Face. I'll recommend the best model for your budget, speed, and accuracy needs.
Can you integrate the chatbot into my website or app?
Yes. I can integrate your AI chatbot or agent into websites, WordPress, mobile apps, WhatsApp, Slack, Telegram, or your existing backend through APIs.
What do I need to provide before we start?
Your project goals, the data or documents the AI should use, any API keys (OpenAI, Claude, etc.), and access details for where it will be integrated. If you're unsure, I offer a free consultation to plan it together.
Who pays for the AI API costs?
API usage costs (OpenAI, Claude, Gemini, vector databases) are billed by those providers to your own account. I'll set it up to keep costs as low as possible and explain expected monthly usage.
Is my data safe and private?
Yes. Your data is only used for your project, stored in your own accounts and databases, and never shared. I can also sign an NDA if needed.
Can you build AI agents that automate tasks?
Yes. I build AI agents that can search the web, read documents, call APIs, update databases, send emails, and automate multi-step workflows using LangChain, LangGraph, and custom tools.
Do you provide support after delivery?
Yes. I offer post-launch support for bug fixes and minor adjustments, plus documentation so you understand how everything works. Ongoing maintenance and new features can be arranged as a custom offer.
Can you fix or improve my existing AI project?
Yes. I can debug, optimize, or upgrade existing chatbots, AI agents, and LLM apps, including improving answer accuracy, speed, and API costs.
Not sure which package fits my project?
Send me a message before ordering. I'll review your requirements and suggest the right package or create a custom offer for you.
