AI-Driven Infinite Loop User Interview System

This workflow utilizes an AI language model to automate user interviews, capable of generating open-ended questions and recording user responses in real-time. Users initiate the interview through a form, and the interview data is stored in a Redis database and synchronized to Google Sheets for easy data analysis and sharing. Users can end the interview at any time, and the interview records can be accessed via a Webhook, ensuring data security and efficient management. This system is suitable for market research, user experience studies, and academic surveys, greatly enhancing the flexibility and efficiency of interviews.

Core Problems Addressed

Traditional user interviews are often time-consuming, labor-intensive, and costly to prepare and execute. This workflow automates the interview process through an AI-driven interviewing agent, reducing human resource demands while enhancing flexibility and efficiency. Real-time data storage and export simplify team analysis and data sharing.

Use Cases

  • Market Research: Gather in-depth user feedback on products or services.
  • User Experience Research: Understand users’ genuine feelings and needs when using products.
  • Academic Surveys: Automate questionnaire-style interviews to collect qualitative data.
  • Remote Interviews: Enable users to participate online anytime without face-to-face interaction.
  • Product Validation: Continuously probe user pain points and improvement suggestions through ongoing questioning.

Main Process Steps

  1. Start Interview: User inputs their name via a web form, triggering the interview process and generating a unique session ID.
  2. Set Interview Topic: The system sets the interview theme (e.g., “Real Driving Test Experience in the UK”).
  3. AI Questioning: The AI interview agent automatically generates the next open-ended question based on the user’s previous answer.
  4. Collect Answers: User responds via the form or inputs “STOP” to end the interview.
  5. Record Data: Each question and answer pair is written in real-time to the Redis session list and simultaneously saved to Google Sheets.
  6. End Interview: Upon detecting the user’s end request, session data is cleared and the user is redirected to the interview completion page.
  7. Display Interview Record: Via Webhook access, users and teams can view a web-based presentation of the complete interview transcript.

Involved Systems and Services

  • n8n Form Trigger: Initiates the interview and collects user input.
