At the edge of your screen
A small orb lives at the edge of your screen. When a message asks something of you, a card slides out beside it with who, what and by when.
Done by Kier
You replied, paid, or merged the fix. Kier sees it happen and ticks the card off for you.
Everywhere you talk
Kier reads the apps you already use, in any language, and turns what's owed into one calm list.
Private by design
Your messages never go to our servers. Kier runs its own models on your Mac, so it works with Wi-Fi off, and nothing leaves unless you hand it to your AI yourself.
Works with your AI
One click starts a session with everything Kier knows: the chat around it and what happened since. Your AI can also ask Kier directly.
For builders
When an AI session goes quiet with a pull request still open or changes never committed, Kier remembers it for you.
Kier runs its own models on Apple Silicon. There is no server in between.
Online helpers stay off until you turn them on. Claude or Codex only when you pick them.
Nothing to sign up for, and nothing synced anywhere. It's yours.
Every morning and evening
At eight in the morning and eight at night, Kier sums up what you owe, what's late and what others still owe you. It can read it aloud in a voice that runs on your Mac.
Your people
Kier keeps a short profile of you, the people you talk to most and your group chats. It refreshes every week, and you can correct it.
Owed to you
When you ask someone for something, Kier keeps it, so you know who to nudge and when.
A vault your AI can ask
Kier gives Claude and Codex a private line into your vault. They search it only when you ask, see only what you allow, and every read is logged on your Mac.
Boundaries
Password managers, banking and health apps are skipped. Kier never logs what you type, and anything you ask it to forget is gone.
From anywhere
Press Option Command K over any app and ask: did I reply to Mum? What's due this week? Kier answers from your vault, on your Mac.
Set up in two minutes
Open it like any Mac app. No account, no sign up.
Switch on your chats, mail and calendar. Change your mind any time.
Kier taps the orb when something needs you, and closes what you've done.
Yes. The app, the local models and every feature are free. There is no account to make and nothing to subscribe to.
No. Kier reads and thinks on your Mac, with models that run on your Mac. The only time anything goes out is when you hand a card to Claude or ChatGPT yourself, and then it goes to them, not to us.
WhatsApp, iMessage, Mail, Discord, your calendar, calls, notifications, and your Claude and Codex sessions. You choose what to switch on. It never reads banking, password or health apps, and it never logs what you type.
It looks at what happened after: your reply in the same chat, a payment confirmation, a merged pull request, a call that took place. When the evidence agrees, the card closes itself and you get a quiet chime. Anything it closed can be put back in one click.
No. Kier works on its own. If you use Claude or Codex, it gives them the full context of a card, so you can hand off the work in one click.
A Mac with Apple Silicon on macOS 14 or later, and about 7 GB of free space for the local model.
No. Kier runs its model itself, inside the app. Setup downloads it once, about 6 GB, and nothing else needs installing.
Yes. Kier reads and thinks on your Mac with its own models, so it keeps working with the Wi-Fi off. Online helpers, like asking GitHub whether a pull request was merged, stay off unless you switch them on.
Only when you let it. Claude and Codex can ask Kier through a connection on your Mac, each one sees only the sources you allow, and every read is logged.
Yes. Tell Kier to forget a chat or a message and it leaves the vault. Kier keeps only a fingerprint, so it won't read it again.

Free, private, and ready in two minutes.
