From “I should” to “hey!”
Three keys, from any app. Kin is there when you think of someone, and gone when you’re done.
Tab peeks at someone first. ⌘K has the rest: call, email, add a note, star.

Say hi
Opens your conversation in Messages.
The right people, already there.
Open Kin and up to eight people are waiting, each with one line that says why. Nothing to sort, nothing to remember.

It’s been a while. Kin notices when someone drifts.
Texting and meetings come from Messages and Calendar, once you connect them.
Catch up before you say hi.
Press Tab on anyone to peek: what you noted, what Kin picked up from your texts, and the last thing they said.
Jot a note the way you’d say it, like she’s at Stripe now
, and Kin keeps their details up to date.
What Kin does with AI
Kin picks out details like a new job or a move from a note you save, and learns about people from your texts on your Mac, so it can suggest a reply or something to bring up next. It never texts anyone as you. Anything Kin changes can be undone for 30 days.
- Runs on your Mac with Apple Intelligence, or with your own Claude key.
- Every change Kin makes can be undone for 30 days.
- Any person can be kept off cloud AI.
- Nothing goes to a cloud model until you set one up.
Questions
Something else? Write to Michael, who makes Kin.
Does Kin cost anything?
No. Kin is free to download and use, and every feature is included. There’s no trial, no plan and no account.
Does Kin need an account?
No. Kin has no accounts. Your contact records live in Apple Contacts and a local file on your Mac.
Where is my data stored?
Contacts stay in Apple Contacts. Kin’s own notes, tags, links, and timeline are in a JSON file in Kin’s container. Settings › Data can export or reset it.
Which Macs does it run on?
macOS 15 Sequoia or later, Apple silicon and Intel. On-device AI needs macOS 26 with Apple Intelligence.
Does Kin change my contacts?
Only when you edit a person in Kin. It never writes to a contact you did not touch, and it never deletes contacts on its own.
What does the AI send, and where?
Nothing unless you turn AI on. On-device AI never leaves your Mac. With your own Claude key, Kin sends what a feature needs when it runs: the person and the message you are replying to, with the chat’s recent messages and your texting style, or a note you just saved. Anyone you mark “Don’t help with” is never sent.
How do updates work?
Kin checks a small update feed and offers new versions in the app. You can turn the automatic check off in Settings › About.
