--- title: Vimputer description: A Mac app for building Karabiner-Elements configs as layers, then writing a real karabiner.json. icon: keyboard --- Vimputer is an editor for [Karabiner-Elements](https://karabiner-elements.pqrs.org). You build layers of key bindings, scope them to apps, and Vimputer writes the `karabiner.json` Karabiner runs. While you use a layer, a which-key HUD lists its keys. Everything runs on your Mac. There is no account and nothing is sent anywhere. **[Get started](/docs/start)** Build a Vim-style navigation layer for Chrome. **[Authoring model](/docs/authoring/model)** Layers, bindings, and variables. **[Recipes](/docs/recipes)** Tap and hold, chords, leader keys, per-app layers. **[Plugins](/docs/integrations/plugins)** Raycast, Paseo, OBS, Shottr, and more. ## What it does One key can act on press, tap, hold, release, after a pause, or when another key goes down, and a trigger can be a chord, a sequence, or a double-tap. Modes are entered with a key; groups follow an app or a condition. Actions go past keystrokes: open apps and URLs, press menu items, and run plugin commands. Already have a `karabiner.json`? [Import it](/docs/integrations/karabiner). Parts the editor can't show yet are kept and written back.
