What is look?

Look is a keyboard first launcher for macOS, Windows, and Linux that lets you open apps, files, folders, clipboard history, and quick commands without touching the mouse. It works as a lightweight alternative to Spotlight on Mac or Raycast, and it runs entirely on your own machine. Once installed, you press a hotkey such as Cmd+Space on Mac or Alt+Space on Windows and Linux, type what you want, and press Enter. Beyond opening apps and files, Look can do inline math like square roots and percentages, kill a running process by its port number with a confirmation step, search your clipboard history for something you copied earlier, translate or look up a word, and run scoped searches by regex, file path, or file kind. Everything runs locally. Search candidates are indexed in a local file on your computer, and the only times Look reaches the internet are when you explicitly ask it to, such as running a web search or a translation lookup. There is no account to create and no telemetry being collected. The project is built to be fast and small. Typical searches complete in under a millisecond on a few thousand indexed items, and it ships as a single native app rather than a heavier framework like Electron, so there is no background daemon eating resources. It comes with sensible presets for common apps out of the box, and you can add more through a configuration file if you want to customize it further. Installation differs by platform: Homebrew on macOS, package managers or an install script on Linux distributions including Arch, Ubuntu, and NixOS, and a PowerShell one-liner on Windows.
