Draft Gmail replies with OpenAI and OpenRouter for an inbox-zero workflow

Automatically draft email replies using AI. This workflow monitors your Gmail inbox, filters out automated emails (newsletters, receipts, notifications), and uses AI to create draft responses only for emails that genuinely need your attention.

Who is this for?
Freelancers, consultants, and business owners who want to reduce email response time while maintaining quality responses.

How it works

AI Classification (OpenRouter) determines if the email needs a human response - automatically filters out newsletters, receipts, system notifications, and marketing emails
Email Draft Agent (OpenAI) generates a contextual draft reply matching your writing style
Gmail saves the draft to your drafts folder
Telegram sends you a notification when drafts are created
