Automatically categorize & sort Gmail emails using AI

This AI-powered Gmail organizer automatically categorizes and sorts incoming emails using advanced natural language processing.

Users can define custom categories (like Orders, Support, Invoices, etc.) in a Google Sheet, and the workflow will analyze email content, assign the appropriate label, and apply it to the corresponding messages in the user's Gmail account. The workflow runs on a schedule, processing a configurable number of unread emails each time. It integrates with Gmail, Google Sheets, and the OpenRouter AI service to enable this intelligent email sorting and organization.

Automate Outlook email responses with OpenAI ChatGPT

This solution helps save time and effort on composing email replies, particularly for high-volume or repetitive inquiries.
