MEET KAI · YOUR DEFAULT AGENT

It notices before
you have to ask.

Kai watches the mail, chat and calendar you choose. When a flight lands in your inbox, it sorts the boring parts and asks about the rest.

You pick what it watchesMail, chat, calendar, orders and trips. Each source has its own switch.
Handle, ask me, or ignoreSet it once per kind of thing. Check-ins it just does. Replies wait for you.
Quiet when you wantQuiet hours hold everything but approvals. Sending, paying and deleting always ask first.

BETWEEN YOU AND THE MODEL

We don't trust
the model's promise.

A Zero Data Retention badge means the provider says they won't keep the prompt. They still have to read it to answer. We don't treat that as privacy.

K-AI sits in the middle, on your machine. Cards, passwords, keys, ID numbers, addresses, emails and phone numbers are swapped for placeholders before a cloud model sees the request. The map stays on your disk. The answer comes back through the same door, and the real values are put back here, so the agent can still fill the form.

A model running on your machine never makes that trip. Names stay, so it knows who you mean. A picture sent to a vision model is not covered. The full account.

K-AI COMPUTER

Its own computer.
Inside yours.

Other agents run your errands on a machine in someone else's data center. K-AI's machine boots on your laptop, with its own browser, terminal and files, and your screen stays yours.

Everything in this frame stays on your machine.

An agent with your card
should answer to you.

Not to an ad business. Not to a transaction fee.

Asks before it pays
Paying, submitting, sending: it stops with the exact amount and waits for your answer.
Wallet stays local
Cards and addresses never sync. The agent fills them in; the numbers never enter its prompt.
Every step on record
Each run keeps its step list: what it searched, clicked and filled.
Memory you can read
What it knows about you sits on your disk. Edit or delete any of it.

Same idea. Different owner.

Fair questions.

What happens when it gets stuck?
It asks you, with options to pick from, then carries on. It doesn't guess on things that matter.
Where does its computer actually run?
On your laptop, as a small Linux virtual machine. The first run downloads the disk image; after that it starts locally.
Do I need to be technical?
No. Download, sign in, pick a model.
Can I use it without the cloud?
Yes. The local app is free and works with local models. Cloud only adds sync and browser access. The agent runs on your device.
Does a cloud model see my card?
Not the number. Before the request leaves your machine, cards, passwords, keys and similar values are replaced with placeholders. The map stays on your disk. Names are not stripped, and a picture you send a vision model goes through as you sent it.

What would you hand off first?
