for macOS · lives on your desktop
A small hand.
A long memory.
Kai wanders your screen, listens when you hold it down and talk, and remembers what you’re building — so it can bring the right thing back before you ask.
where it lives
Not another window.
A small one, always open.
Kai sits in your menu bar and wanders the edge of your desktop. Flip its palm open for chat, notes, tasks, meetings, and memory — then it tucks itself away again.
presence
It's there. It notices you're there too.
Kai isn't a window you open — it's a small creature that wanders the edges of your screen on its own. Get close and it hesitates. Move fast and it flees. Poke it and it reacts, in one of dozens of small gestures. Less an app, more a housemate.
push to talk
Hold it down. Say what you need.
Press and hold the Hand, talk, let go. It transcribes on-device, thinks out loud in a small floating reply, and streams the answer back while it’s still forming the thought — no spinner, no waiting out a round trip in silence.
memory
It remembers what you’re building.
Every meeting, every calendar event, every Claude Code session becomes part of a running memory — threads that track what you’re actually working on, not just what you typed five minutes ago. While you’re away, it quietly reviews what it’s seen, names the threads that matter, and nudges you back toward the ones that have gone quiet.

the palm

Chat
Ask it anything, right from the palm. Same conversation whether you type or talk.
Flip its palm open and this is what’s there — six faces, one for each thing it does. Keep scrolling to turn it.
for teams · what’s next
One Hand per person.
One memory for the team.
Every Kai on a team can, with permission, contribute to a shared organizational memory — so when someone changes roles or leaves, what they knew doesn’t leave with them. This is where Kai is headed next: not just a personal assistant, but the thing that makes a team’s institutional memory outlast any one person’s tenure.
