A private newsletter
for family and close friends.

Write one thoughtful letter, add the photos that matter, and send it to the people who actually want to hear from you. Keep it inside your circle, or share a private read-only link so someone can read one letter without creating an account. No feeds. No followers. No likes.

What is KinLetter?

You think about them more often than they hear from you. KinLetter gives you a simple place to write a private letter about life lately, collect a few photos, and send it without turning it into social media.

It is for weekly updates, family news, trip recaps, kid photos, and the small stories that are too personal for a feed but too meaningful to disappear in a group chat.

That's the product: private letters for the people you choose.

1

Write a private letter

Start with a few notes or a full draft. Add photos and shape it into a Short, Standard, or Long letter.

2

Review it in your own voice

Use gentle writing help when you want it, then edit freely so the final letter still sounds like you.

3

Send, or send and share

Send to your circle in the app, or share a private read-only link for one letter so someone can read it without an account.

Made for letters, not feeds

Every choice in KinLetter supports one loop: write a private letter, send it to your people, hear back, and want to write again.

Letters with room to breathe

Use KinLetter for the kind of update that deserves more than a text: a weekly family note, a life update, a travel recap, or a few photos with context.

Two ways to send

Choose Send to my circle when everyone is already in KinLetter, or Send and share link when you want to include someone who is not signed up yet.

Private previews, no account needed

A shared letter link opens a read-only preview of that one letter, including photos. Links are unguessable and expire after 14 days.

Private & safe by design

There are no public profiles, follower counts, or discovery feeds. Your circle stays private, and shared preview links show only the letter you choose to share.

What KinLetter is not.

The product gets a lot of its character from what we left out. We didn't run out of time on these. We chose not to build them, on purpose.
