## What is CornerLetter?

[Find Your Peace in a Noisy World]
In an era flooded with instant messaging, Corner offers a quiet sanctuary for your thoughts. It is an asynchronous "slow mail" and diary app designed to help you slow down.
No read receipts, no instant replies—just the warmth of traditional letter writing.

[Key Features]
Slow Mail, Sincere Words
Delivery time depends on the actual distance between penpals. A letter from New York to Paris might take days. We turn waiting into beautiful anticipation.

The Art of Letter Writing
Select textured stationeries, custom postmarks, and even attach a background melody to your letter. Here, writing is a solemn and beautiful experience.

Stamps & The World
A small stamp is your ticket to a distant place. Collect limited-edition stamps from around the globe and attach them to your letters.

Diary & Inspiration
Save your fleeting thoughts, a photo of a cloud, or a daily mood in your "Diary". They will become the perfect inspiration when you sit down to write.

Find True Penpals
Connect with people who still appreciate the art of reading and writing long letters. Sincerity between the lines is the only way to build a healthy penpal relationship here.

### 5/5 — 挺不错的，真心推荐

*2026-01-06*

真的很喜欢一隅的氛围，安安静静的，没有乱七八糟的社交推荐和广告。每次看到信件显示“在途”，心里居然真的会有那种小时候等信的期待感。在这个快节奏的时候，能慢下来写点东西挺不容易的。提个小建议： 希望以后信纸的样式能再多一点，现在的虽然好看，但写多了感觉选择稍微有点少。会一直支持的，加油
