Why Kakuchi

Light, private, and yours to keep.

What Kakuchi promises, and the short facts people ask about first: price, requirements, AI, data and installation.

LightEasy on your battery

A widget only reads data while it’s on screen, and everything rests when your display sleeps.

PrivateStays on your Mac

No account. Widgets list the sites they talk to, and your AI key and widget secrets live in your Keychain.

Multi-displayEvery screen

Choose the main display, all displays or a specific one, and the notch shelf follows your pointer.

FamiliarBring your widgets

Have a folder of classic desktop widgets? Drop it in and they run as they are.

No lock-inPay once

Kakuchi is a one-time purchase. There's no subscription, and the AI uses your own key, so there's no monthly AI fee.

CarefulAsks first

Anything that runs commands, uses the network or reads files is listed for your approval. Previews never run commands.

OpenWorks with your tools

A built-in MCP server gives compatible assistants and coding tools 15 ways to build, preview and place widgets for you.

NativeLooks like the Mac

Liquid Glass on macOS 26, light and dark, ten themes, and a settings form for every widget.
