KinLetter is a private way to keep your inner circle in the loop — the warmth of a newsletter for the people who matter. Share what's going on in your life, and KinLetter shapes it into a post, note, or full letter. No public profiles. No followers. No likes. No algorithms. Just you, and the ones who want to hear from you.
Currently in review. Sign up the day we launch.
Think of it as a small, private newsletter — one that goes only to your parents, your siblings, the cousin you used to see every summer, and the two or three friends who've been around forever. The people who'd actually want to know that the dog won't stop staring at the ceiling fan, that you finally beat your dad at chess, that the baby slept through.
Jot a few notes whenever the mood strikes. KinLetter shapes them into a warm, personal letter — the kind you'd write to your grandmother if you had three more hours in the day — and sends it out, privately, to the handful of people you've invited.
That's it. That's the whole product.
Type a few notes, or just talk — KinLetter listens. Speech stays on your device.
Your notes become a warm, personal update written in your voice. Edit it freely before sending.
Only the people you've invited can read it. No public link, no shareable URL, no audience.
Every choice in KinLetter is in service of one thing: that it should feel like a letter to family and close friends, not a feed.
KinLetter remembers the recurring parts of your life — your dog's name, your kids' ages, your move last March — so you don't have to re-explain them every time you write.
Walking, driving, cooking — talk into the app and the words become a letter. Speech-to-text runs on-device. The audio never leaves your phone.
Only the people you've invited can read your letters — no public link, no shareable URL, no audience beyond your circle. We don't sell your personal information or share it with advertisers.
Each letter can include a single photo — optional, but never more than one. No albums, no photo dumps, no carousels. Just one image that captures the moment, or none at all.
No streak counters, no nudges, no "you haven't posted in 3 days." Write when there's something worth saying — once a month, twice a week, whenever.
Letters live as letters. If someone wants to react, they text you — like the friend they are.
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.
KinLetter is launching soon on iPhone and Android. We'll let you know the moment it's ready.
