Privacy

Your desktop is personal.

This PC only

This PC only is on

Stays on your PC.

Your PC, your data

Events, history and settings live on this machine. Online services are used only for what you turn on.

This PC only

One switch keeps a chat on a local model. It still answers with Wi-Fi off.

Keys stay locked

API keys go to Windows Credential Manager, never a plain file. Copied secrets clear from the clipboard in 30 seconds.

Asks first

Safe actions can run on their own. Everything else waits for one click, and anything destructive always asks.

Read the privacy notes

Voice

Just say it.

Two reviews are waiting, and your standup notes are half done. Want me to draft them?

Speech runs on your PC. Talk over a reply to stop it, and answer without the wake word.

Any brain you like

Not technical? Low on specs? Fine.

Meet the creature

A little fur. A lot of feelings.

And so much more

A drawer full of little things.

Small moments where one click saves five. Switch any of them on, off or to automatic, or teach it new ones in YAML.

Morning brief

The first time you sit down: meetings, reviews waiting on you, and the apps you always open. Open all, and you are ready.
