Kaku

Kaku is an open source terminal emulator for Mac with an AI assistant built in. It is designed to work as soon as it is installed, with fonts, themes, shortcuts and shell integration preconfigured so there is no config file to write first. No account is required. The terminal provides tabs and split panes with familiar shortcuts, restores windows, panes and working directories on relaunch, and uses a GPU accelerated native core. It bundles a terminal file manager, Git diffs through Lazygit, a Yazi file manager integration, remote file mounting in SSH sessions and smart tab completion. Configuration is done in Lua. Kaku Assistant suggests a fix when a command fails, which the user can paste at the prompt with a shortcut and nothing runs automatically. It also turns a plain English description into a shell command and opens an AI chat panel. The assistant connects to a user supplied OpenAI compatible service and model, or a Codex CLI login, which the user sets up with the kaku ai command. Kaku is for developers who work in the command line and want a terminal with AI help included. It installs from a DMG or through Homebrew. The site publishes it as free, and structured data on the site lists a price of zero. The site also offers a comparison with iTerm2, Warp, Ghostty and WezTerm.
