KinLetter is a private way to keep your inner circle in the loop. Share what's going on in your life, and KinLetter shapes it into a note or a full update. No public profiles. No followers. No likes. No algorithms. Just you, and the ones who want to hear from you.
You think about them more often than they hear from you. KinLetter makes staying in touch effortless. Jot a few notes or just talk, and AI turns it into something worth reading. Everything stays private, just between you and your circle.
You talk, AI writes. You ask, Kin catches you up. No effort, no guilt, no falling behind. Just people who care about each other, actually staying in touch.
That's it. That's the whole product.
Type a few notes, add some photos, or just talk. KinLetter listens. Speech stays on your device.
Your notes become a 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 an update for the people you care about, not a feed.
Kin remembers the recurring parts of your life so you never have to re-explain yourself. Talk or type back and forth to stay up to date on your circle, write an update, or just chat about anything.
Send a direct message to anyone in your circle. Completely private, just between the two of you. No group chats, no read receipts. Just a simple, private conversation.
Send a video moment to your circle. Up to 60 seconds, recorded live, just for the people who matter. Video Moments are personal and ephemeral: they disappear after 7 days.
Only the people you've invited can see your updates. Every note and reply passes through an AI content filter before it reaches anyone. No public links, no audience beyond your circle.
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.
