# Newsletter summariser app

Replit Agent built a Gmail newsletter summariser for a low-coder, with batch summaries, deduplication, archiving and export, over three days.

Result: The author shipped a working summariser targeting a cut from 2-3 weekly hours of newsletter reading to 30 minutes.

## How it was set up

Replit Agent, driven by natural language prompts, connected to Gmail. The author has basic Python knowledge.

## Worth knowing

Needs a Google email account, and the author notes clear limitations of the tool. Time saved is the target, not a measured result.

## Prompt

```text
Develop a simple [app type] with a clean, responsive interface and [number] main functions: [function 1], [function 2], [function 3]. Save data locally so it persists between sessions.
```

## Evidence note

Author's account with screenshots; no repo, app shared on request
