Overview

Stop digging through execution logs to find out why a workflow failed. This template provides a "set-it-and-forget-it" monitoring system that uses AI to automatically debug your n8n workflows.

Instead of just getting a simple error message, you'll receive a detailed email notification with a root cause analysis and a step-by-step suggested fix from a Gemini-powered AI agent. This saves you valuable time, helps you resolve issues faster, and ensures your critical automations are always running smoothly.
