The Problem
Manually reviewing dozens of daily emails is time-consuming and leads to missed important messages. Researchers and professionals need a way to get quick, intelligent summaries delivered to a platform they already use.
The Solution
This n8n workflow runs on an hourly schedule, fetches new emails from Gmail, aggregates them, passes the content through an OpenAI-powered AI agent with conversational memory, and sends a clean summary to a private Telegram chat, all fully autonomous.
