It taps you when someone is waiting.
A small orb lives by the notch. When a message asks something of you, a card slides out with who, what and by when.

At the top of your screen
A small orb lives by the notch. When a message asks something of you, a card slides out 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 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 8 GB of free space for the local model.
