01 · Tabs & panes
Tabs and splits that feel like the rest of macOS.
New tabs, split panes, and navigation use the shortcuts you already expect. Broadcast input across panes when you want to drive several at once.
02 · Assistant
A failed command should be more than red text.
When a command fails, Kaku drafts a fix for review. Press Cmd + Shift + E to paste it back, and nothing dangerous runs on its own. Type # plus a sentence to turn plain language into a command.

05 · Why Kaku
A terminal should let you start working first.
I live in the terminal. I used Alacritty for years for its speed, then wanted stronger tabs and panes as my work shifted toward AI coding. Kaku builds on a fast, proven engine, adds practical defaults and shell tools, and puts an assistant within reach, all in one fast, quiet macOS app.

06 · Questions
Common questions
- How do I install Kaku?
- Download the DMG from GitHub Releases, or use the Homebrew tap:
brew install tw93/tap/kakuku. An unrelatedkakupackage exists, so the tap avoids the wrong one. - How is Kaku different from iTerm2?
- iTerm2 is a mature macOS terminal. Kaku is a lighter, faster alternative with practical defaults, fast tabs and panes, a curated shell suite, and an AI assistant, ready out of the box.
- How is Kaku different from Warp?
- Warp is closed source and built around a cloud account. Kaku is MIT open source, requires no account, and AI requests only go to the Provider you configure.
- Is Kaku paid?
- No, Kaku is an MIT-licensed open source project.
- Does Kaku run on Windows or Linux?
- Not yet, the current focus is getting the native macOS experience solid first.
