AI-Based Chatbot SaaS Platform

The challenge

Businesses needed intelligent chatbots that could answer customer questions about their specific services and FAQ.

What I built

Built a SaaS platform where users can subscribe to AI chatbots configured with their business information using vector databases for accurate, contextual responses.

Results

• Deployed intelligent chatbots for multiple clients
• Automated customer support with contextual responses
• Subscription-based revenue model implemented
• Reduced customer service workload significantly

Tech stack

• Next.js
• OpenAI API
• n8n
• PostgreSQL
• Vector Database

Code sketch

A simplified illustration of the core logic, not production code.

// AI Chatbot with Vector Database
const processChatMessage = async (message, clientId) => {
  // Retrieve client-specific knowledge base
  const clientKnowledge = await vectorDB.query({
    vector: await embedMessage(message),
    filter: { client_id: clientId },
    topK: 5
  });
  
  // Generate response using OpenAI with context
  const response = await openai.createCompletion({
    model: "gpt-3.5-turbo",
    messages: [
      { role: "system", content: `You are a helpful assistant for ${clientKnowledge.company}` },
      { role: "user", content: message }
    ],
    context: clientKnowledge.documents
  });
  
  return response.choices[0].message.content;
};
