NO INSTALL. NO DAEMON. JUST PRESS THE KEY.

Press ⌘0

Then click anything below. Retype the copy, nudge the padding, recolor a button, delete a card. This is the real CmdZero overlay — the same one that rewrites your source.

On Windows and Linux, press Ctrl+0
BUTTONS

Select one and use the style dock on the left — size, padding, radius, colour.

BADGES

Small targets. Try retyping one, or bumping its radius to a pill.

CARDS

Delete one with the trash icon, or drag the grip to reorder. ⌘Z puts it back.

Retyping a headline is a string splice in an AST. No model needs to read your file to do that, so none does.

Padding, radius, colour and size resolve to a deterministic rewrite. The overlay updates the DOM before the write even lands.

Everything else
69%cheaper than an agent

Ambiguous changes route to a model sized for the job, scoped to the one file your element actually lives in.

NATURAL LANGUAGE

Select the panel below, press ⌘0 again, and describe a change. In the sandbox the model call is scripted — locally it runs headless Claude against the one mapped file.

Sandbox: edits are applied in your browser and reset on reload — nothing is written to disk and no model is called. Install CmdZero locally and the same overlay rewrites your real source files.
