# Build a newsletter summarizer that cuts weekly reading to 30 minutes

Consultant Justin Tan, a self-described low-coder, used Replit Agent over three days to build an app that pulls newsletters from Gmail, removes duplicate stories, summarizes them and archives the emails. His weekly newsletter reading dropped from 2-3 hours to two 15-minute sessions.

### Steps

1. Describe the app to Replit Agent: connect Gmail, find newsletters, summarize them
2. Connect your Google account and an AI model API key when it asks
3. Test on a week of real newsletters and point out duplicate or missed stories
4. Add an archive step so processed emails leave your inbox
5. Run it on a schedule, such as twice a week

### Prompt

```
Build a web app that connects to my Gmail, finds emails with the label 'Newsletters' from the last 7 days, extracts the main stories, merges stories that several newsletters cover, and shows a single digest with a 2-sentence summary and source link for each story. Add a button that archives all the processed emails. Use a simple login so only I can use it.
