AI Chatbot with Conditional Execution for Cost Efficiency

Description

This n8n workflow implements an AI-powered chatbot that only runs when a chat is initiated on a website. By introducing a conditional step, the workflow ensures that AI tokens are not consumed unnecessarily, making it a cost-efficient and resource-optimized solution.

The chatbot, named Sophia, serves as an interactive assistant for SyncBricks. It helps users with guest posting services, YouTube review videos, IT consultancy, and online courses while collecting user details step by step. The chatbot ensures that inquiries are properly logged and confirmed before proceeding to AI-driven responses.

This template is ideal for businesses, service providers, and content creators who want to optimize AI token usage while delivering personalized, interactive engagement with their users.

Features

1. Conditional Execution – The AI chatbot only activates when a chat is initiated, avoiding unnecessary API calls.
2. AI-Powered Conversations – Uses Google Gemini AI to generate human-like responses.
3. Step-by-Step Data Collection – Ensures structured user input, requesting name, email, and request type sequentially.
4. Memory Buffer for Context Awareness – Maintains conversation context using a window buffer memory system.
5. Multiple Service Offerings – Supports inquiries related to:
   • Guest Posting Services
   • YouTube Review Videos
   • Online Courses on Udemy
   • IT Consultancy Services
6. Automated Confirmation Messages – After collecting user details, sends a confirmation message summarizing the request.

How It Works

1. Chat Message Trigger

   • The workflow starts only when a chat message is received from the website.
   • This ensures no AI token is consumed unless a user initiates a chat.

2. Condition Check: Is Chat Input Provided?

   • The workflow checks if chat input is non-empty.
   • If the chat input is empty, the workflow stops, ensuring no unnecessary API usage.
   • If a message is detected, the chatbot continues processing.

3. AI-Powered Chat Response

   • The chatbot, Sophia, generates personalized responses using Google Gemini AI.
   • AI ensures structured conversation flow by collecting:
     • User’s Full Name
     • Email ID
     • Request Type

4. Memory Buffer for Context Retention

   • A Window Buffer Memory system stores chat history and retrieves previous responses to ensure context-aware conversations.

5. Response Optimization

   • Checks memory to avoid asking the same question twice.
   • If details are already provided, Sophia moves directly to processing the request.

6. Confirmation & User Engagement

   • After collecting the required details, Sophia summarizes the request as follows:
     • "Got it [Name], your request is [Request Type]. I will be sending the details to your email ID: [Email]. Hold on while I send confirmation."

7. Final Confirmation Message

   • Ensures the user receives a proper acknowledgment of their inquiry.
