🚀 Built a Private AI Customer Support Chatbot using Phi-3, Python, .NET, and SQL Server.
The chatbot answers customer queries using a company's internal FAQs, documentation, and support knowledge base without relying on expensive external AI APIs.
⚙️ How it works
• Knowledge base converted into vector embeddings using sentence-transformers
• User query processed via .NET Core API
• Python service performs semantic search to find relevant answers
• Context sent to Phi-3 LLM to generate a response
• Instant reply returned to the chat interface
✅ Fully self-hosted AI solution
✅ Works with private company data
✅ Low operational cost
✅ Easy integration with websites or apps
Excited about building AI-powered support systems and private LLM solutions for businesses.

An AI customer support chatbot for a fictional Nigerian food delivery business, Lagos Fresh Kitchen. It runs on n8n Cloud and uses Claude Haiku 5.5 as the AI model. The workflow is three nodes: a chat trigger receives the customer’s message, an AI Agent processes it, and the Anthropic Chat Model writes the answer.
How it behaves
The AI Agent has a system message that sets the rules. It must answer only from the business information, never invent prices, areas, hours or policies, and use a fixed fallback line when the answer isn’t there: “I don’t have enough information to answer that accurately. Please contact our support team.”
The business information it knows
Open Monday to Saturday, 9 AM to 8 PM, closed Sundays
Delivers to Lagos Mainland (Ikeja, Yaba, Surulere, Maryland, Ojota, Gbagada) and Island areas (Victoria Island, Ikoyi, Lekki), not outside Lagos
Delivery takes 30 to 60 minutes, with fees from ₦1,000
Menu of jollof rice, fried rice, rice and stew, pounded yam with egusi, grilled chicken, suya and soft drinks
Payments by card, transfer and cash on delivery
Cancellation allowed before cooking starts
No Sunday orders or Sunday delivery, and no event catering
Refunds, complaints and order status go to support
AI can build your website.
It cannot understand who you are, how you are different and how to explain that to people through a website.
A clear story takes judgment.
