FAQ
Do you offer refunds?
Yes, we offer refunds if we fail to deliver satisfactory results.
Is my business data safe with your AI solution?
Absolutely. Security is my top priority. I use secure API connections and store all vector embeddings in private databases like PostgreSQL with pgvector or MongoDB Atlas Vector Search. Your data remains fully isolated it's never used for training external models, and I implement strict access contro
Can the AI bot read and process our real-time data?
Yes! I design systems that can sync with live MongoDB collections and other databases in real-time. Whether you need hourly updates or continuous streaming, I implement change data capture (CDC) patterns to keep your AI's knowledge current with your latest documents, customer data
Do I need to provide my own API keys?
I offer flexible options. For development and testing, I can use my managed API keys. For production, I strongly recommend you provide your own OpenAI or Anthropic account for maximum security and billing control. I'll guide you through secure key management best practices.
How do you prevent AI hallucinations in responses?
Through carefully engineered RAG (Retrieval-Augmented Generation) architecture. Every answer is grounded in your actual documents with source citations. I implement multiple verification layers including confidence scoring, cross-referencing, and fallback protocols to ensure hallucination-free answe
What is RAG and how is it different from regular ChatGPT?
RAG (Retrieval-Augmented Generation) lets AI search your documents, PDFs, databases, and websites before answering. Unlike regular ChatGPT, it provides accurate, business-specific responses based on your own data.
Can you integrate this into my existing website or app?
Yes. I can integrate the RAG AI chatbot into your website, SaaS platform, web app, customer portal, or internal system using APIs, widgets, or custom UI components.
What data sources do you support?
I support PDFs, Word files, websites, FAQs, PostgreSQL, MySQL, cloud storage, APIs, and custom knowledge bases. Most digital data sources can be connected to your chatbot.
Do I need an OpenAI API key?
Yes, in most cases. Using your own OpenAI API key gives you full control over usage, billing, and ownership. I can guide you through the setup if needed.
Will my data be secure?
Yes. Your data remains confidential and is used only for development and testing. Secure architectures, private databases, access controls, and NDA support are available upon request.
