Key Features and Highlights

This workflow leverages an AI language model to engage in real-time natural language conversations with customers. It intelligently recognizes and extracts dish names, quantities, and table numbers from orders, automatically validates and confirms order details, and finally structures the order data for batch writing into Google Sheets. This enables automated and digitalized order processing and management.

Core Problems Addressed

  • Traditional ordering processes are prone to data entry errors, missing quantities or table numbers, resulting in low service efficiency.
  • Diverse colloquial expressions and spelling mistakes pose challenges for accurate order recognition.
  • The need to rapidly convert unstructured text orders into data formats usable by backend systems.
  • Automating order data archiving and enabling real-time tracking to facilitate operational management.

Application Scenarios

Ideal for restaurants, cafes, bars, and other food and beverage establishments. The chatbot assists waitstaff in communicating with customers to take orders, enabling automatic parsing and electronic storage of orders. Particularly beneficial during peak hours to improve order efficiency and reduce human errors.

Main Workflow Steps

  1. Receive Customer Chat Messages: Capture customer order text via chat trigger nodes.
  2. AI Intelligent Dialogue Interaction: Use AI agent nodes to guide customers in confirming orders, handling missing information and correcting spelling errors.
  3. Information Extraction: Employ LangChain extraction nodes to identify dishes, quantities, and table numbers from orders.
  4. Conditional Check: Verify if extraction results are empty; if so, skip processing.
  5. Python Code Processing: Split the extracted raw JSON order data into individual order items.
  6. Loop Batch Processing: Process each order item iteratively.
  7. Write Data to Google Sheets: Append each order record (including dish, quantity, table number, and timestamp) to a specified Google Sheet.
  8. Invoke Sub-Workflow (optional): Pass processed order data to downstream workflows such as the restaurant POS system.
