KakuchiPick your plan
Claude Pro or Max works through Claude Code, Anthropic's own tool. ChatGPT Plus or Pro works through Codex, OpenAI's tool, which also comes with the Codex app. A Google account works through Antigravity.
Kakuchi runs the official tool on your Mac. You sign in through that tool, so Kakuchi never sees or stores your sign-in.
Connect it
- 1Open Settings › AI and choose Subscription.
- 2Pick Claude Code, Codex or Antigravity as the provider. The Connection section shows whether the tool is installed and signed in.
- 3If it isn't signed in yet, sign in once using the tool's own flow, then choose Check Again.
- 4Click Test Connection. It sends one small request to make sure everything works.
Build a widget
- 1Click Create Widget and describe what you want in plain words, like “a countdown to my holiday with a photo”.
- 2The builder writes the widget, looks at a preview of it and fixes what it gets wrong. You see each version as it goes.
- 3Click Add to Desktop (or Add to Menu Bar) when you like it. To change a widget later, right-click it and choose Edit Widget, then Change Design with AI.
Questions
- Does this cost extra?
- Not from Kakuchi. Building widgets counts toward your plan's usage limits, the same as using the tool yourself.
- Do I need an API key?
- No. A subscription needs no key. If you'd rather use one, choose API Key in Settings › AI instead.
- Can every plan see the widget's preview?
- Claude Code and Codex look at a picture of the widget to check how it looks. Antigravity works from text only, so it gets the widget's errors and details instead.
