Employee time tracking system with GPT-4o reports & Gmail notifications

Overview This workflow acts as an AI-powered smart time tracker for employees or personal use. It records work sessions via a webhook, logs start/end/break times into n8n Data Tables, and uses OpenAI to automatically summarize working patterns and send reminders or monthly reports via Gmail.

How It Works 1. Webhook /track-time → Receives a POST request with a method (start, break, or end) and duration if applicable. 2. Switch Logic → Directs the request to create or update the appropriate record in your Data Table. 3. Data Tables → Store timestamps, break durations, and worker IDs in a secure local table. 4. Schedule Triggers - Daily (10:00) → Checks if today’s shift was not started and sends a reminder. - Monthly (Day 1, 06:00) → Compiles last month’s working data and sends an AI report to management. 5. OpenAI Analysis - Summarizes working hours and productivity trends. - Detects missed clock-ins or irregular patterns. 6. Gmail Integration → Sends formatted daily or monthly reports to both employees and supervisors.
