What This Workflow Does
This workflow scans Gmail inbox every minute to catch new emails quickly.
It takes the email’s subject, recipient, body, and headers and organizes them clearly.
The email’s HTML content is turned into a screenshot image using the hcti.io API.
ChatGPT-4 AI analyzes the email to check if it might be phishing using the LangChain node.
Then the workflow makes a Jira ticket with all extracted info and the screenshot attached.
This helps security teams act fast on suspicious emails with full text and visuals.
