Workflow Name

Product Satisfaction Survey Chatbot — DJI Mini 2 Survey Assistant

Key Features and Highlights

This workflow utilizes a Telegram chatbot to automatically guide users through a satisfaction survey for the DJI Mini 2 drone. It integrates Google Sheets to store survey questions and user responses, employs Redis for state management and session tracking, and incorporates the OpenAI GPT model to intelligently generate in-depth follow-up questions. This combination significantly enhances the interactivity and depth of the survey. Users can control the survey flow with simple commands such as skipping questions or resetting the survey, ensuring a flexible and user-friendly experience.

Core Problems Addressed

Traditional online surveys often lack interactivity, leading to user drop-off and difficulty in uncovering genuine insights. This workflow leverages a chatbot combined with AI-driven intelligent Q&A to dynamically follow up on user answers, automatically determining when deeper probing is needed, thereby improving survey quality and user engagement. Additionally, Redis supports concurrent multi-user state management, ensuring data consistency and smooth process flow.

Application Scenarios

  • Product satisfaction surveys
  • User feedback collection
  • Market research and demand exploration
  • Customer service experience evaluation
  • Any online survey scenario requiring structured and in-depth interviews

Main Process Steps

  1. Users initiate or continue the survey by sending commands (e.g., /start or /next) via the Telegram bot.
  2. The workflow reads the current list of survey questions and user progress from Google Sheets.
  3. Redis stores and updates the user’s current Q&A state to manage sessions.
  4. The bot sends the current question to the user and receives their response.
  5. A text classifier determines whether the answer requires an in-depth follow-up.
  6. If follow-up is needed, the OpenAI GPT intelligent AI agent generates subsequent questions for deeper interaction.
  7. User responses and AI-generated interactions are synchronized back to Google Sheets, updating the user’s survey record.
  8. Upon completion of all questions, the bot sends a survey completion notification and supports restarting the survey.
