Automated customer support with GPT-4o-mini AI triage for Google Forms & Gmail

How it works

When someone submits your Google Form, this workflow:

• Triggers instantly from new Google Sheets row
• Analyzes with AI to determine urgency (low/medium/high), category (technical/sales/support/billing), and sentiment (positive/neutral/negative)
• Routes intelligently based on priority level to appropriate response template
• Generates personalized reply using OpenAI, tailored to urgency and sentiment
• Sends auto-reply via Gmail with professional formatting
• Alerts your team on Slack for high-priority cases requiring human follow-up
• Logs everything to tracking sheet for analytics and audit trail

Modify response templates:

Customize the three response generation nodes to match your brand voice. Add company-specific information, policies, or FAQ links. Adjust tone from formal to casual based on your audience.
